Updated List of Claims about GMD Effectiveness (February 24, 2020)

This is an updated list (previous version was August 20, 2019) of claims by U.S. government officials about the effectiveness of the U.S. Ground-Based Midcourse (GMD) national missile defense system. It adds five additional claims (#s 60, 61, 62, 63, and 64).

A developing theme in recent statements, following the cancellation of the Redesigned Kill Vehicle, is that while the GMD system is currently highly effective, it will start to lose effectiveness in the mid to late 2020s, as the threat increases and the current interceptors age. Thus, the argument goes, there is an urgent need to upgrade the system soon.

(1) September 1, 2000: “… I simply cannot conclude, with the information I have today, that we have enough confidence in the technology and the operational effectiveness of the entire NMD system to move forward to deployment. Therefore, I have decided not to authorize deployment of a national missile defense at this time.” President Bill Clinton, at Georgetown University, September 1, 2000.

(2) March 18, 2003:Effectiveness is in the 90% range.[1]   Edward Aldridge, Undersecretary of Defense for Acquisition, Technology and Logistics.

(3) March 23, 2003:There are a lot of things that go into [determining] effectiveness. Everybody can be right.[2] MDA Director Ronald Kadish, in response to a question about Aldridge’s statement.

(4) July 21, 2005: “We have a better than zero chance of intercepting, I believe, an inbound warhead.” That confidence will improve with time.” MDA Director Lt. General Henry Obering.[3]

(5) March 14, 2006:When the president declares limited defensive operational capability, we are prepared as the shooter, if you will, to execute the mission to defend our country. And I’m very confident in the efficacy of that system.[4] Admiral Timothy Keating, Commander of U.S. Northern Command.

(6) June 2006:(From) what I have seen and what I know about the system and its capabilities I am very confident.[5] MDA Director Lt. Gen. Henry Obering.

(7) July 6, 2006:If it headed to the United States, we’ve got a missile defense system that will defend our country.” President George W. Bush in response to a question on Larry King Live about North Korea’s unsuccessful test of a long-range ballistic missile the day before.

(8) September 1, 2006:I would say that if we had to use the system in an operational mode, it would be very capable.[6] MDA Director Lt. Gen. Henry Obering.

(9) January 29, 2007: “We are Confident The Ballistic Missile Defense System Would Have Operated As Designed Had The Taepo Dong-2 Threatened The U.S.,” MDA Deputy Director Brigadier General Patrick O’Reilly.[7]

(10) October 2, 2007:– does the system work? The answer to that is yes. Is it going to work against more complex threats in the future? We believe it will.” MDA Director Lt. Gen. Henry Obering.[8]

(11) November 2, 2008:I have very high confidence we could defend the United States against that threat.[9] MDA Director Lt. Gen. Henry Obering, about one or two missiles launched from North Korea.

(12) March 27, 2009:And Senator, I’ll tell you, if we felt the North Koreans were going to shoot a ballistic missile at us today, I am comfortable that we would have an effective system able to meet that threat.”[10] General Victor Renaurt, Commander U.S. Northern Command, U.S. Africa Command and U.S. Transportation Command.

(13) June 9, 2009:I think that the judgement and advice I got was that the 30 silos we have now, or are under construction, are fully adequate to protect us against a North Korean threat for a number of years.[11] And “I have confidence that if North Korea launched a long-range missile in the direction of the United States, that we would have a high probability of being able to defend ourselves against it.” Secretary of Defense Robert M. Gates.

(14) June 16, 2009: Confidence that a North Korean missile could be shot down is: “ninety percent plus.”[12] MDA Director Lt. Gen. Patrick O’Reilly.

(15) June 18, 2009 (approximately): “I’d believe we have a reasonable chance” of intercepting a North Korean missile. Director of Operational Test and Evaluation Charles McQueary, in an interview on his last day in the job.[13]

(16) July 28, 2009:Well, we have a very proven missile system in the area of missiles coming out of North Korea.[14] MDA Director Lt. Gen. Patrick O’Reilly.

(17) April 21, 2010:It is the belief of the — of the leaders of this department that we have the capability to defend the United States against the — against an ICBM threat from a rogue nation such as Iran or North Korea. We are confident in the system we have at this point.[15] Geoff Morrell, Pentagon Press Secretary.

(18) December 1, 2010: “…the probability will be well in the high 90s today of the GMD system being able to intercept that today.” MDA Director Patrick O’Reilly in response to a question from Representative Trent Franks about countering “one ICBM coming from Tehran to New York.”[16]

(19) April 13, 2011:The posture we have today is one that has us well-protected against the initial ICBMs that might be deployed by states like North Korea and Iran with — that are few in number, relatively slow and lack sophisticated countermeasures.”[17] Bradley Roberts, Deputy Assistant Secretary of Defense for Nuclear and Missile Defense Policy.

(20) December 12, 2012: “I’m very confident that American defense capabilities are able, no problem, to block a rocket like this one.” U.S. Secretary of Defense Leon Panetta, in response to a question from CNN on the capability of U.S missile defenses, December 12, 2012.[18]

(21) March 7, 2013: “I can tell you that the United States is fully capable of defending against any North Korean ballistic missile attack. And our recent success in returning to testing of the upgraded version of the so-called GBI, or the CE2 missile, will keep us on a good trajectory to improve our defense capability against limited ballistic missile threats such as those from North Korea. But let’s be clear, we are fully capable of dealing with that threat.” White House Press Secretary Jay Carney, in response to a question at White House Daily Press Briefing, March 7, 2013.[19]

(22) March 15, 2013: “We have confidence in our system. And we certainly will not go forward with the additional 14 interceptors until we are sure that we have the complete confidence that we will need. But the American people should be assured that our interceptors are effective.” Secretary of Defense Chuck Hagel, in response to a question at a Pentagon press conference, March 15, 2013.

(23) April 9, 2013:I believe we have a credible ability to defend the homeland, to defend Hawaii, to defend Guam, to defend our forward-deployed forces and defend our allies.” Admiral Samuel Locklear, Commander, U.S. Pacific Command, Senate Armed Services Committee, April 9, 2013 in response to a question about intercepting North Korean missiles.[20]

(24) May 9, 2013:We do have confidence in the ability of the ballistic missile defense system to defend the United States against a limited attack from both North Korea and Iran today and in the near future.” Lt. General Richard Formica, Commander of the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command and Commander of the Joint Functional Component Command for Integrated Missile Defense, in response to a question from Senator Mark Udall about the capability of “our current GMD system to defend all of the United States, including the East Coast, against current and near-term ballistic missile threats from both North Korea and Iran?”[21]

(25) May 9, 2013:The East Coast is well-protected as the result of — well, it was protected before the additional — and this additional ’14 provides additional protection both for anything from North Korea as well as anything from Iran should that threat develop.” Madelyn Creedon, Assistant Defense Secretary for Global Strategic Affairs, in response to a question from Senator Mark Udall (and referring to the recently announced plan to deploy 14 additional interceptors in Alaska).[22]

(26) July 2013: “I stand by my response in the testimony I provided on May 9.” Lt. General Richard Formica, Commander of the U.S. Army Space and Missile Defense Command, when asked about the effectiveness of the GMD System shortly after failure of FTG-07 on July 5, 2013.[23]

(27) July 10, 2013: But we maintain that we have a robust missile defense system in place to defend the United States and our allies from a range of threats.”   “We have a range of assets that can support American missile defense, and we are confident that we can defend this country from the missile threat.” Pentagon Press Secretary George Little , July 9 2013 (four days after the failed FTG-07 intercept test of the GMD system).[24]

(28) Sometime before August 21, 2013: “Of course you’re protected. Yes, you’re protected. We’re proud to protect you.” MDA Director Vice Admiral James Syring, in response to the question “Am I protected where I live?” asked by a person sitting next to him on an airplane.[25]

(29) March 25, 2014: Regarding the GMD system: “We have confidence in the current capability. Do we need to do more? Do we need to continue to do the necessary testing? Yes. But we have confidence in the operational employment, the rules of engagement that we would use that would address maybe some reliability or some uncertainty associated with the system.” Lieutenant General David L. Mann, Commanding General U.S. Army Space and Missile Defense Command/Army Strategic Forces Command and Joint Functional Component Command for Integrated Missile Defense.[26]

(30) March 25, 2014: “As a policy official who is often briefed by those who develop and operate the system, I am confident that the Ground-based Midcourse Defense system can defend the United States against a limited intercontinental ballistic missile attack.” Elaine M. Bunn, Deputy Assistant Secretary for Defense for Nuclear and Missile Defense Policy.[27]

(31) March 19, 2015: Regarding the GMD system: “We have high confidence in the ability of this system to defeat an ICBM strike against the United States from an enemy with limited ICBM capabilities.” Admiral Bill Gortney, Commander North American Aerospace Command and U.S. Northern Command.[28]

(32) March 25, 2015: Regarding the GMD system: “As the Secretary of Defense and various Combatant Commanders have previously testified, the Warfighter remains confident in our ability to protect the Nation against a limited intercontinental ballistic missile attack, even in the face of the changing fiscal environment.” Lieutenant General David L. Mann, Commanding General U.S. Army Space and Missile Defense Command/Army Strategic Forces Command and Joint Functional Component Command for Integrated Missile Defense.[29]

(36) April 14, 2016: In response to a question about the GMD system’s coverage of Hawaii: “We’re prepared to engage and protect Hawaii, Alaska and the rest of the states with the existing system and have high confidence in its success.” Admiral Bill Gortney, Commander North American Aerospace Defense Command and U.S. Northern Command.[33]

(37) December 2016: “Previous assessments of the Ground-based Midcourse Defense (GMD) system remain unchanged. GMD has demonstrated a limited capability to defend the U.S. Homeland from small numbers of simple intermediate-range or Intercontinental ballistic missile threats launched from North Korea or Iran. DOT&E cannot quantitatively assess GMD performance due to lack of ground tests supported by accredited modeling and simulation (M&S).”[34] J. Michael Gilmore, Director, Operational Test and Evaluation.

(38) January 3, 2017: “We have a ballistic missile defense, a missile defense umbrella that we’re confident in for the region and to protect the United States homeland and we’ll continue to be confident in it, given where we are today in the technology and the skill with which our forces are using the – that technology.”[35] Pentagon Press Secretary Peter Cook, in response to a question.

(39) January 9, 2017:I am very confident in the system and procedures” the U.S. Northern Command, which operates the missile shield “will employ to intercept a North Korean ICBM were they to shoot it towards our territory.”[36] MDA Director Vice Admiral James Syring, in response to a question about the DOT&E assessment in (37) above.

(40) April 6, 2017: “I am extremely confident of our capability to defend the United States of America and be able to intercept an ICBM should it reach our homeland” and “Today we have exactly what we need to defend the United States of America against North Korea.” [37] General Lori Robinson, Commander U.S. Northern Command and Commander, North American Aerospace Command.

(41) April 11, 2017: “I’ve read articles, you read it in the paper, ‘Oh it’s only got a 50 percent hit rate.’ I’d take 50 percent.”[38] Major General Jeffrey L. Bannister, Commander, Fort Drum, New York (one of three sites under consideration as a possible east coast GMD deployment site).

(42) April, 2017: The Pentagon “is confident in our ability to defend the homeland against ballistic missile threats.” “… we have made significant improvements over the last several years to ensure the system is able to operate as designed.”[39] Chris Johnson, MDA spokesman.

(43) May 30, 2017. This system is vitally important to the defense of our homeland, and this test demonstrates that we have a capable, credible deterrent against a very real threat.[40] Vice Admiral James Syring, Director of the U.S. Missile Defense Agency, following a successful test of the U.S. GMD national missile defense system.

(44) June 2017. It’s at least as good as a coin toss. (the chance that any individual interceptor could down a warhead at the time the system was set up in 2004).[41] Lt. General (retired) Patrick O’Reilly, former Director of the Missile Defense Agency.

(45) July 22, 2017. The United States military can defend against a limited North Korea attack on Seoul, Japan and the United States.[42] General Joe Dunford, Chairman of the U.S. Joint Chiefs of staff speaking about North Korea’s missile threat.

(46) July 30, 2017. As the commander responsible for defending the homeland, I want to assure our citizens the USNORTHCOM remains unwavering in our confidence that we can fully defend the United States against this ballistic missile threat.[43] General Lori Robinson, Commander of the North American Aerospace Defense Command and U.S. Northern Command, speaking about the North Korean ballistic missile threat.

(47) August 2017. Yes, we believe that the currently deployed ballistic missile defense system can meet today’s threat and we’ve demonstrated that capability through testing.[44] Lt. General Samuel Greaves, Director of the Missile Defense Agency.

(48) August 2017. 100 per cent confidence the missile system would work.[45] Col. Kevin Kick, Commander of the 100th Missile Defense Brigade (Fort Greely and Vandenberg).

(49) September 6, 2017. If your children tonight ask if we’re safe from North Korea, I will tell you we have the strongest defense possible against that threat right now, today.[46] Rear Admiral Jon Hill, Deputy Director of the U.S. Missile Defense Agency.

(50) September 2017. Very confident in the United States’ ability to protect all 50 states.[47] General John Hyten, Commander of U.S. Strategic Command.

(51) October 11, 2017. We have missiles that can knock out a missile in the air 97 percent of the time, and if you send two of them, it’s going to get knocked down.[48] U.S. President Donald Trump discussing the North Korean ICBM threat in an interview with Sean Hannity on Fox News, October 11, 2017.

(52) February 15, 2018. I am 100 percent confident in my ability to defend the United States of America. General Lori Robinson, Commander of U.S. Northern Command in response to the question “So to be clear, do you have confidence in the ability of the GMD system to defend the United States from a North Korean ballistic missile attack?” asked by Senator Deb Fischer.[49]

(53) March 22, 2018. So I believe we are perfectly positioned to defense against today’s threat. Missile Defense Agency Director Lt. General Samuel Greaves in response to a question about the North Korean missile threat asked by Senator Deb Fischer.[50]

(54) April 17, 2018. Senator she has. And I would say with high confidence that I believe that the ground-based midcourse defense system in place today has the ability to defend against a North Korea ballistic missile strike. General Terrence O’Shaughnessy, at the hearing for his nomination to be the next Commander of the U.S. Northern Command when asked by Senator James Inhofe if he had been convinced by the statement by the current Northern Command Commander General Lori Robinson that the GMD system would be 100% effective (see February 15, 2018 quote).[51]

(55) January 17, 2019. The United States is protected against a limited ICBM as a result of investments made in the ground-based mid-course defense (GMD) system, the employment of which is planned and executed by U.S. Northern Command (USNORTHCOM). The GMD system is designed to defnd against a limited ICBM attack from rogue states such as North Kores (see Figure 20), and potentially IRAN, but in the event of conflict, it would be used to defend, to the extent feasible, against a ballistic missile attack on the U.S. homeland from any source[52]. Office of the Secretary of Defense, 2019 Missile Defense Review, January, 2019, p. 41.

(56) April 12, 2019. To me, it’s very simple. If a rogue nation or other entity shoots an ICBM, inter-continental ballistic missile, at us, we intercept it[53]. Major Jason Brewer, chief of missile defense operations with the Colorado Army National Guard’s 100th missile defense brigade (which operates the U.S. GMD national missile defense system).

(57) July 19, 2019. Well I’d say first off, we are in a very good place. I can – I can very confidently say right now we have the ability to defend against the ballistic missile threat, for example, that we face from North Korea, as an example. That is an incredibly important capability to maintain and to continue to advance going forward.[54] General Terrence O’Shaughnessy, Commander U.S. Northern Command and North American Aerospace Defense Command, in response to a question about where he thought we should be headed on ballistic missile defense.

(58) August 13, 2019. I have a great deal of confidence in the technical capabilities of the system. Now if we want more rounds we are—you know as I like to say with all the systems you get to the point where you can’t buy the parts anymore you have parts obsolescence issues. So if we want more rounds, we are going to have to have a redesign kill vehicle, and we are pursuing that. But the system we have in the ground today is—is obviously quite capable[55]. Michael Griffin, Under Secretary of Defense for Research and Engineering in response to a question about his confidence in the GMD national missile defense system during a presentation at the Hudson Institute.

(59) August 13, 2019. We know how to do it with existing technology. It would require buying system that we don’t have today; it would require buying more of some of the systems we do have. So it becomes a—it becomes a budgetary priority. You—you would be spending money on missile defense systems that we today are spending another things so that is a budget priority discussion and it is a deterrence policy which I don’t engage, but it is not a technical issue. We know how to do it[56]. Michael Griffin, Under Secretary of Defense for Research and Engineering in response to a question about whether the policy not to deploy a robust homeland defense against Russia and China was due to technical problems to policy decisions.

(60) October 16, 2019. I have no concerns right now. I am confident in the capability we have right now. Lt. General James Dickinson, commander of the U.S. Army Space and Missile Defense Command, about the U.S. Ground Based Midcourse national missile defense system, following the decision to cancel the Redesigned Kill Vehicle.[57]

(61) January 17, 2020. They are. I have – I have 100 percent confidence. Literally – I don’t say 100 percent very often. I have 100 percent confidence in those capabilities against North Korea. General John E. Hyten, Vice Chairman of the Joint Chiefs of Staff, at the Center for Strategic and International Studies in response to the question “Do you think current missile defense systems of the United States are capable of protecting the United States from North Koreans – North Korea’s new missiles?”[58]

(62) January 28, 2020. According to NORTHCOM, while we can be confident in our current GMD posture to counter a North Korean threat for the next five or six years, at the rate North Korea is developing their capabilities, we must begin assuming increased risk around 2025 and beyond. Representative Doug Lamborn at a hearing of the House Armed Services Committee.[59]

(63) January 28, 2020. I do share that assessment with NORTHCOM. John Rood, Under Secretary of Defense for Policy, at the same House Armed Services Committee hearing.[60]

(64) February 10, 2020. So if you have an existing fleet [of GBI interceptors]like we have today that we’re very confident in, it handles the current threat, we can defend Hawaii, we can defend the continental United States against the threats that — where they stand today. We know they’re going to evolve. So we know that sometime in the mid to late ‘20s, you’ll start to see a fall-off in the ability of that missile to take on those threats, You’ll start to see reliability issues, right? Just kind of normal for any weapons system that’s deployed for that long. Missile Defense Agency Director Vice Admiral Jon A. Hill at a press briefing on the FY 2021 MDA Budget.[61]

And Some Quotes on Defending Guam (also see #23):

(61) April 2017. The chances of any missile or missiles getting though in my calculation is .000001 – that’s five zeros – percent.[62] George Charfauros, Guam’s homeland security advisor.

(62) August 12, 2017. We are with you 1000 percent, you are safe. U.S. President Donald Trump in a phone call to Guam Governor Eddie Calvo.[63]

(63) August 12, 2017. We are all over this…the wonderful island of Guam is very well protected, White House Chief of Staff John Kelly in a phone call to Guam Governor Eddie Calvo.[64]

(64) August 14, 2017. You know, Guam is well protected. U.S. Secretary of Defense Jim Mattis.[65] Online at:

(65) August 2017. Guam is very heavily protected by missile defense systems at sea and also on the ground. They are very proven missile defense systems.[66] Lt. General (retired) Patrick O’Reilly, former Director of the Missile Defense Agency.

(66) September 2017. Guam is very well protected against North Korean missile attack.[67] General John Hyten, Commander of U.S. Strategic Command.

[1] BAYH: Let me withdraw the question and move on. I think you see where I was heading.

Let me ask you Mr. — Secretary Aldridge, about the effectiveness of the system that’s to be deployed in 2004 and 2005 in protecting against this developing North Korean threat — the 10 land-based missiles proposed for the end of fiscal year 2004 — how effective would they be against the North Korean missile if it were, in fact, launched against our country?

ALDRIDGE: Well, we think that it would be effective. Probably shouldn’t go into a lot of details of…

BAYH: Well, how do you define effective — 90 percent success rate — 75 — 50?

ALDRIDGE: Yes, sir — you would — and you — the way you could achieve these rates is you don’t have to fire just one interceptor per target, you could fire two, as we do in PAC-3.

BAYH: Of course.

ALDRIDGE: And so the effectiveness is in the 90 percent range. Of course, we want the effectiveness to be high enough that we never have to use these things. I mean, that’s the ultimate effectiveness is that they’re never used.

BAYH: There are — there are — there are — there are 10 going online in 2004 — 10 in 2005. The radar is not going to be available — when will that go into place — 2006?

ALDRIDGE: Well, General Kadish has probably got the specific dates for all of those. Let him…

KADISH: We’ll have radars online to handle the early warning and usefulness of the system in ’04, when we put the missiles on alert if everything works out all right. We’ll add the sea-based X-band (ph) if it proves out by — the following year — it’s currently scheduled by September of ’05.

BAYH: So, Secretary Aldridge, your testimony is that with the 10 interceptors going in at the end of fiscal year ’04 and the radar that will be online at that time, we would have a 90 percent effectiveness in shooting down a NATO (ph) Dong II?

ALDRIDGE: Well, it depends on — a lot depends on the continuation of the — of the test and the effective — this precise effectiveness numbers. But I would put — you know, as of today, the projected effectiveness would be in the 90 percent range.

[12] SEN Bayh: I’ve bumped up against my time limits here, but there was one final question. You’re briefing the President of the United States. He asks you based on — you know, he’s got to take into consideration what you’re doing in terms of facing these threats. He asks you if there is a rogue launch, what are the percentages that we’re going to be able to hit it and bring it down, what would you tell him?

GEN. O’Reilly: Ninety percent plus.

SEN. Bayh: Ninety percent plus confidence that we could — if there’s a rogue launch from North Korea, let’s say, we could intercept that target and bring it down?

Gen. O’Reilly: Yes. Sir.

The missiles, we actually test them out of Vandenberg, but they’re up at Fort Greely. And then for Hawaii, we have multiple systems (inaudible). A theater high-altitude-area defense system, its an Army mobile system, and then we have the Navy Aegis system.

Updated List of Claims about GMD Effectiveness (August 20, 2019)

This is an updated list (previous version was May 31, 2018)  of claims by U.S. government officials about the effectiveness of the U.S. Ground-Based Midcourse (GMD) national missile defense system.  It adds five additional claims (#s 55, 56, 57, 58 and 59).

(1) September 1, 2000: “… I simply cannot conclude, with the information I have today, that we have enough confidence in the technology and the operational effectiveness of the entire NMD system to move forward to deployment. Therefore, I have decided not to authorize deployment of a national missile defense at this time.”  President Bill Clinton, at Georgetown University, September 1, 2000.

(2) March 18, 2003:  “Effectiveness is in the 90% range.[1]   Edward Aldridge, Undersecretary of Defense for Acquisition, Technology and Logistics.

(3) March 23, 2003:There are a lot of things that go into [determining] effectiveness.  Everybody can be right.[2] MDA Director Ronald Kadish, in response to a question about Aldridge’s statement.

(4) July 21, 2005: “We have a better than zero chance of intercepting, I believe, an inbound warhead.”  That confidence will improve with time.”  MDA Director Lt. General Henry Obering.[3]

(5) March 14, 2006:When the president declares limited defensive operational capability, we are prepared as the shooter, if you will, to execute the mission to defend our country.  And I’m very confident in the efficacy of that system.[4]  Admiral Timothy Keating, Commander of U.S. Northern Command.

(6) June 2006:(From) what I have seen and what I know about the system and its capabilities I am very confident.[5]  MDA Director Lt. Gen. Henry Obering.

(7) July 6, 2006:If it headed to the United States, we’ve got a missile defense system that will defend our country.” President George W. Bush in response to a question on Larry King Live about North Korea’s unsuccessful test of a long-range ballistic missile the day before.

(8) September 1, 2006:I would say that if we had to use the system in an operational mode, it would be very capable.[6] MDA Director Lt. Gen. Henry Obering.

(9) January 29, 2007: “We are Confident The Ballistic Missile Defense System Would Have Operated As Designed Had The Taepo Dong-2 Threatened The U.S.,” MDA Deputy Director Brigadier General Patrick O’Reilly.[7]

(10) October 2, 2007:– does the system work? The answer to that is yes. Is it going to work against more complex threats in the future?  We believe it will.”  MDA Director Lt. Gen. Henry Obering.[8]

(11) November 2, 2008:I have very high confidence we could defend the United States against that threat.[9] MDA Director Lt. Gen. Henry Obering, about one or two missiles launched from North Korea.

(12) March 27, 2009:And Senator, I’ll tell you, if we felt the North Koreans were going to shoot a ballistic missile at us today, I am comfortable that we would have an effective system able to meet that threat.”[10]  General Victor Renaurt, Commander U.S. Northern Command, U.S. Africa Command and U.S. Transportation Command.

(13) June 9, 2009:I think that the judgement and advice I got was that the 30 silos we have now, or are under construction, are fully adequate to protect us against a North Korean threat for a number of years.[11] And “I have confidence that if North Korea launched a long-range missile in the direction of the United States, that we would have a high probability of being able to defend ourselves against it.”  Secretary of Defense Robert M. Gates.

(14) June 16, 2009: Confidence that a North Korean missile could be shot down is: “ninety percent plus.”[12]  MDA Director Lt. Gen. Patrick O’Reilly.

(15) June 18, 2009 (approximately):  “I’d believe we have a reasonable chance” of intercepting a North Korean missile.  Director of Operational Test and Evaluation Charles McQueary, in an interview on his last day in the job.[13]

(16) July 28, 2009:Well, we have a very proven missile system in the area of missiles coming out of North Korea.[14]  MDA Director Lt. Gen. Patrick O’Reilly.

(17) April 21, 2010:It is the belief of the — of the leaders of this department that we have the capability to defend the United States against the — against an ICBM threat from a rogue nation such as Iran or North Korea.  We are confident in the system we have at this point.[15]  Geoff Morrell, Pentagon Press Secretary.

(18) December 1, 2010: “…the probability will be well in the high 90s today of the GMD system being able to intercept that today.” MDA Director Patrick O’Reilly in response to a question from Representative Trent Franks about countering “one ICBM coming from Tehran to New York.”[16]

(19) April 13, 2011:The posture we have today is one that has us well-protected against the initial ICBMs that might be deployed by states like North Korea and Iran with — that are few in number, relatively slow and lack sophisticated countermeasures.”[17]  Bradley Roberts, Deputy Assistant Secretary of Defense for Nuclear and Missile Defense Policy.

(20) December 12, 2012: “I’m very confident that American defense capabilities are able, no problem, to block a rocket like this one.”  U.S. Secretary of Defense Leon Panetta, in response to a question from CNN on the capability of U.S missile defenses, December 12, 2012.[18]

(21) March 7, 2013: “I can tell you that the United States is fully capable of defending against any North Korean ballistic missile attack.  And our recent success in returning to testing of the upgraded version of the so-called GBI, or the CE2 missile, will keep us on a good trajectory to improve our defense capability against limited ballistic missile threats such as those from North Korea.  But let’s be clear, we are fully capable of dealing with that threat.”  White House Press Secretary Jay Carney, in response to a question at White House Daily Press Briefing, March 7, 2013.[19]

(22) March 15, 2013: “We have confidence in our system.  And we certainly will not go forward with the additional 14 interceptors until we are sure that we have the complete confidence that we will need.  But the American people should be assured that our interceptors are effective.”  Secretary of Defense Chuck Hagel, in response to a question at a Pentagon press conference, March 15, 2013.

(23) April 9, 2013:I believe we have a credible ability to defend the homeland, to defend Hawaii, to defend Guam, to defend our forward-deployed forces and defend our allies.”  Admiral Samuel Locklear, Commander, U.S. Pacific Command, Senate Armed Services Committee, April 9, 2013 in response to a question about intercepting North Korean missiles.[20]

(24) May 9, 2013:We do have confidence in the ability of the ballistic missile defense system to defend the United States against a limited attack from both North Korea and Iran today and in the near future.” Lt. General Richard Formica, Commander of the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command and Commander of the Joint Functional Component Command for Integrated Missile Defense, in response to a question from Senator Mark Udall about the capability of “our current GMD system to defend all of the United States, including the East Coast, against current and near-term ballistic missile threats from both North Korea and Iran?”[21]

(25) May 9, 2013:The East Coast is well-protected as the result of — well, it was protected before the additional — and this additional ’14 provides additional protection both for anything from North Korea as well as anything from Iran should that threat develop.”  Madelyn Creedon, Assistant Defense Secretary for Global Strategic Affairs, in response to a question from Senator Mark Udall (and referring to the recently announced plan to deploy 14 additional interceptors in Alaska).[22]

(26) July 2013: “I stand by my response in the testimony I provided on May 9.”  Lt. General Richard Formica, Commander of the U.S. Army Space and Missile Defense Command, when asked about the effectiveness of the GMD System shortly after failure of FTG-07 on July 5, 2013.[23]

(27) July 10, 2013:  But we maintain that we have a robust missile defense system in place to defend the United States and our allies from a range of threats.”   “We have a range of assets that can support American missile defense, and we are confident that we can defend this country from the missile threat.” Pentagon Press Secretary George Little , July 9 2013 (four days after the failed FTG-07 intercept test of the GMD system).[24]

(28) Sometime before August 21, 2013:  “Of course you’re protected. Yes, you’re protected.  We’re proud to protect you.”  MDA Director Vice Admiral James Syring, in response to the question “Am I protected where I live?” asked by a person sitting next to him on an airplane.[25]

(29) March 25, 2014: Regarding the GMD system: “We have confidence in the current capability.  Do we need to do more?  Do we need to continue to do the necessary testing?  Yes. But we have confidence in the operational employment, the rules of engagement that we would use that would address maybe some reliability or some uncertainty associated with the system.” Lieutenant General David L. Mann, Commanding General U.S. Army Space and Missile Defense Command/Army Strategic Forces Command and Joint Functional Component Command for Integrated Missile Defense.[26]

(30) March 25, 2014: “As a policy official who is often briefed by those who develop and operate the system, I am confident that the Ground-based Midcourse Defense system can defend the United States against a limited intercontinental ballistic missile attack.”  Elaine M. Bunn, Deputy Assistant Secretary for Defense for Nuclear and Missile Defense Policy.[27]

(31) March 19, 2015: Regarding the GMD system: “We have high confidence in the ability of this system to defeat an ICBM strike against the United States from an enemy with limited ICBM capabilities.”  Admiral Bill Gortney, Commander North American Aerospace Command and U.S. Northern Command.[28]

(32) March 25, 2015: Regarding the GMD system: “As the Secretary of Defense and various Combatant Commanders have previously testified, the Warfighter remains confident in our ability to protect the Nation against a limited intercontinental ballistic missile attack, even in the face of the changing fiscal environment.” Lieutenant General David L. Mann, Commanding General U.S. Army Space and Missile Defense Command/Army Strategic Forces Command and Joint Functional Component Command for Integrated Missile Defense.[29]

(33) October 7, 2015: Speaking about the North Korean ICBM threat to the U.S. homeland: “We’re ready for him, and we’re ready 24 hours a day if he should be dumb enough to shoot something at us.” Admiral Bill Gortney, Commander North American Aerospace Defense Command and U.S. Northern Command, at an Atlantic Council event, October 7, 2015.[30]

(34) April 13, 2016: In response to a question about missile defense coverage of Hawaii: “The people of Hawaii are protected today from the North Korean threat.” MDA Director Vice Admiral James D. Syring.[31]

(35) April 13, 2016: “The U.S. homeland is currently protected against potential ICBM attacks from States like North Korea and Iran if it was to develop an ICBM in the future.” Brian P. McKeon, Principal Deputy Under Secretary of Defense for Policy.[32]

(36) April 14, 2016: In response to a question about the GMD system’s coverage of Hawaii: “We’re prepared to engage and protect Hawaii, Alaska and the rest of the states with the existing system and have high confidence in its success.” Admiral Bill Gortney, Commander North American Aerospace Defense Command and U.S. Northern Command.[33]

(37) December 2016: “Previous assessments of the Ground-based Midcourse Defense (GMD) system remain unchanged. GMD has demonstrated a limited capability to defend the U.S. Homeland from small numbers of simple intermediate-range or Intercontinental ballistic missile threats launched from North Korea or Iran. DOT&E cannot quantitatively assess GMD performance due to lack of ground tests supported by accredited modeling and simulation (M&S).”[34] J. Michael Gilmore, Director, Operational Test and Evaluation.

(38) January 3, 2017: “We have a ballistic missile defense, a missile defense umbrella that we’re confident in for the region and to protect the United States homeland and we’ll continue to be confident in it, given where we are today in the technology and the skill with which our forces are using the – that technology.”[35]  Pentagon Press Secretary Peter Cook, in response to a question.

(39) January 9, 2017:I am very confident in the system and procedures” the U.S. Northern Command, which operates the missile shield “will employ to intercept a North Korean ICBM were they to shoot it towards our territory.”[36] MDA Director Vice Admiral James Syring, in response to a question about the DOT&E assessment in (37) above.

(40) April 6, 2017: “I am extremely confident of our capability to defend the United States of America and be able to intercept an ICBM should it reach our homeland” and “Today we have exactly what we need to defend the United States of America against North Korea.” [37] General Lori Robinson, Commander U.S. Northern Command and Commander, North American Aerospace Command.

(41) April 11, 2017: “I’ve read articles, you read it in the paper, ‘Oh it’s only got a 50 percent hit rate.’ I’d take 50 percent.”[38] Major General Jeffrey L. Bannister, Commander, Fort Drum, New York (one of three sites under consideration as a possible east coast GMD deployment site).

(42) April, 2017: The Pentagon “is confident in our ability to defend the homeland against ballistic missile threats.” “… we have made significant improvements over the last several years to ensure the system is able to operate as designed.”[39]  Chris Johnson, MDA spokesman.

 (43) May 30, 2017. This system is vitally important to the defense of our homeland, and this test demonstrates that we have a capable, credible deterrent against a very real threat.[40]  Vice Admiral James Syring, Director of the U.S. Missile Defense Agency, following a successful test of the U.S. GMD national missile defense system.

(44) June 2017. It’s at least as good as a coin toss. (the chance that any individual interceptor could down a warhead at the time the system was set up in 2004).[41]  Lt. General (retired) Patrick O’Reilly, former Director of the Missile Defense Agency.

(45) July 22, 2017. The United States military can defend against a limited North Korea attack on Seoul, Japan and the United States.[42]  General Joe Dunford, Chairman of the U.S. Joint Chiefs of staff speaking about North Korea’s missile threat.

(46) July 30, 2017. As the commander responsible for defending the homeland, I want to assure our citizens the USNORTHCOM remains unwavering in our confidence that we can fully defend the United States against this ballistic missile threat.[43]  General Lori Robinson, Commander of the North American Aerospace Defense Command and U.S. Northern Command, speaking about the North Korean ballistic missile threat.

(47) August 2017. Yes, we believe that the currently deployed ballistic missile defense system can meet today’s threat and we’ve demonstrated that capability through testing.[44]  Lt. General  Samuel Greaves, Director of the Missile Defense Agency.

(48) August 2017. 100 per cent confidence the missile system would work.[45] Col. Kevin Kick, Commander of the 100th Missile Defense Brigade (Fort Greely and Vandenberg).

(49) September 6, 2017. If your children tonight ask if we’re safe from North Korea, I will tell you we have the strongest defense possible against that threat right now, today.[46]  Rear Admiral Jon Hill, Deputy Director of the U.S. Missile Defense Agency.

(50) September 2017. Very confident in the United States’ ability to protect all 50 states.[47] General John Hyten, Commander of U.S. Strategic Command.

(51) October 11, 2017.  We have missiles that can knock out a missile in the air 97 percent of the time, and if you send two of them, it’s going to get knocked down.[48]  U.S. President Donald Trump discussing the North Korean ICBM threat in an interview with Sean Hannity on Fox News, October 11, 2017.

(52) February 15, 2018. I am 100 percent confident in my ability to defend the United States of America. General Lori Robinson, Commander of U.S. Northern Command in response to the question “So to be clear, do you have confidence in the ability of the GMD system to defend the United States from a North Korean ballistic missile attack?” asked by Senator Deb Fischer.[49]

(53) March 22, 2018. So I believe we are perfectly positioned to defense against today’s threat. Missile Defense Agency Director Lt. General Samuel Greaves in response to a question about the North Korean missile threat asked by Senator Deb Fischer.[50]

(54) April 17, 2018. Senator she has.  And I would say with high confidence that I believe that the ground-based midcourse defense system in place today has the ability to defend against a North Korea ballistic missile strike. General Terrence O’Shaughnessy, at the hearing for his nomination to be the next Commander of the U.S. Northern Command when asked by Senator  James Inhofe if he had been convinced by the statement by the current Northern Command Commander General Lori Robinson that the GMD system would be 100% effective (see February 15, 2018 quote).[51]

(55) January 17, 2019. The United States is protected against a limited ICBM as a result of investments made in the ground-based mid-course defense (GMD) system, the employment of which is planned and executed by U.S. Northern Command (USNORTHCOM). The GMD system is designed to defend against a limited ICBM attack from rogue states such as North Kores (see Figure 20), and potentially IRAN, but in the event of conflict, it would be used to defend, to the extent feasible, against a ballistic missile attack on the U.S. homeland from any source[52]. Office of the Secretary of Defense, 2019 Missile Defense Review, January, 2019, p. 41.

(56) April 12, 2019. To me, it’s very simple. If a rogue nation or other entity shoots an ICBM, inter-continental ballistic missile, at us, we intercept it[53].  Major Jason Brewer, chief of missile defense operations with the Colorado Army National Guard’s 100th missile defense brigade (which operates the U.S. GMD national missile defense system).

(57) July 19, 2019. Well I’d say first off, we are in a very good place. I can – I can very confidently say right now we have the ability to defend against the ballistic missile threat, for example, that we face from North Korea, as an example. That is an incredibly important capability to maintain and to continue to advance going forward.[54] General Terrence O’Shaughnessy, Commander U.S. Northern Command and North American Aerospace Defense Command, in response to a question about where he thought we should be headed on ballistic missile defense.

(58) August 13, 2019. I have a great deal of confidence in the technical capabilities of the system. Now if we want more rounds we are—you know as I like to say with all the systems you get to the point where you can’t buy the parts anymore you have parts obsolescence issues. So if we want more rounds, we are going to have to have a redesign kill vehicle, and we are pursuing that. But the system we have in the ground today is—is obviously quite capable[55]. Michael Griffin, Under Secretary of Defense for Research and Engineering in response to a question about his confidence in the GMD national missile defense system during a presentation at the Hudson Institute.

(59) August 13, 2019. We know how to do it with existing technology. It would require buying system that we don’t have today; it would require buying more of some of the systems we do have. So it becomes a—it becomes a budgetary priority. You—you would be spending money on missile defense systems that we today are spending another things so that is a budget priority discussion and it is a deterrence policy which I don’t engage, but it is not a technical issue.  We know how to do it[56]. Michael Griffin, Under Secretary of Defense for Research and Engineering in response to a question about whether the policy not to deploy a robust homeland defense against Russia and China was due to technical problems to policy decisions.

[1] BAYH: Let me withdraw the question and move on. I think you see where I was heading.

Let me ask you Mr. — Secretary Aldridge, about the effectiveness of the system that’s to be deployed in 2004 and 2005 in protecting against this developing North Korean threat — the 10 land-based missiles proposed for the end of fiscal year 2004 — how effective would they be against the North Korean missile if it were, in fact, launched against our country?

ALDRIDGE: Well, we think that it would be effective. Probably shouldn’t go into a lot of details of…

BAYH: Well, how do you define effective — 90 percent success rate — 75 — 50?

ALDRIDGE: Yes, sir — you would — and you — the way you could achieve these rates is you don’t have to fire just one interceptor per target, you could fire two, as we do in PAC-3.

BAYH: Of course.

ALDRIDGE: And so the effectiveness is in the 90 percent range. Of course, we want the effectiveness to be high enough that we never have to use these things. I mean, that’s the ultimate effectiveness is that they’re never used.

BAYH: There are — there are — there are — there are 10 going online in 2004 — 10 in 2005. The radar is not going to be available — when will that go into place — 2006?

ALDRIDGE: Well, General Kadish has probably got the specific dates for all of those. Let him…

KADISH: We’ll have radars online to handle the early warning and usefulness of the system in ’04, when we put the missiles on alert if everything works out all right. We’ll add the sea-based X-band (ph) if it proves out by — the following year — it’s currently scheduled by September of ’05.

BAYH: So, Secretary Aldridge, your testimony is that with the 10 interceptors going in at the end of fiscal year ’04 and the radar that will be online at that time, we would have a 90 percent effectiveness in shooting down a NATO (ph) Dong II?

ALDRIDGE: Well, it depends on — a lot depends on the continuation of the — of the test and the effective — this precise effectiveness numbers. But I would put — you know, as of today, the projected effectiveness would be in the 90 percent range.

New Aegis Radar to be 100 Times More Sensitive than Current Radar (May 22, 2019)

New Aegis Radar to be 100 Times More Sensitive than Current Radar (May 22, 2019)

In my post of February 11, 2019, I discussed a number of planned new S-band radars, including the Navy’s Air and Missile Defense Radar (AMDR), which is scheduled to begin deployment on the Navy’s new Flight III Aegis destroyers in about 2023. In that discussion, I used the standard claim that the AMDR, also designated the SPY-6(V)1, would be about 15 dB = 30 times more sensitive than the current SPY-1 radar on U.S. Navy cruisers and destroyers.  I also noted, however, that there were some recent indications the AMDR might be even more sensitive, possibly by a factor of 40-70 over the SPY-1.

Now, following developmental testing of the AMDR, the Navy has validated a Raytheon Company (the manufacturer of the AMDR) assessment that the radar’s actual sensitivity is almost 100 times that of the SPY-1.[1]

The Technical Director of Raytheon’s Seapower Capability Systems, Curt von Braun, explained that “The 30 was an original number. But [during] the test period out at Pacific Missile Range Facility, we’ve been realizing additional sensitivity through our design margins that have now been tested.  So we’re more at liberty to advertise the better performance than was designed in the margins and now those are being officially realized by the radar.”[2]

According to Scott Pence, Raytheon’s Director of Naval Radar Systems, “SPY-6(V)1 is approximately 20 dB more sensitive than the SPY-1 – nearly 100 times – which translates to more than three times the original requirement” and that “SPY-6 also delivers a significant increase in range to the legacy radar.”[3]

Assuming the two radars were operated in exactly the same way (which seems unlikely), a factor of 100 in sensitivity would result in about a 3.2 times range increase against a given target.

What Did FTG-11 Actually Prove? (April 4, 2019)

On March 25, 2019 the U.S. Missile Defense Agency (MDA) conducted FTG-11, a salvo test of the US Ground-based Midcourse Defense (GMD) system in which two interceptors were fired, just under a minute apart, at a single ICBN-range missile.  

In a press release later that day, MDA described the test as follows:

“This test was the first salvo engagement of a threat-representative ICBM target by two Ground Based Interceptors (GBI), which were designated GBI-Lead, and GBI-Trail for the test. The GBI-Lead destroyed the reentry vehicle, as it was designed to do. The GBI-Trail then looked at the resulting debris and remaining objects, and, not finding any other reentry vehicles, selected the next ‘most lethal object’ it could identify, and struck that, precisely as it was designed to do.”

The MDA press release stated that “Initial indications show the test met requirements.”  It also quoted MDA Director Air Force Lt. General Samuel A. Greaves:

“The system worked exactly as it was designed to do, and the results of this test provide evidence of the practicable use of the salvo doctrine within missile defense. The Ground-based Midcourse Defense system is vitally important to the defense of our homeland, and this test demonstrates that we have a capable, credible deterrent against a very real threat.”

At yesterday’s (April 3, 2019) hearing on missile defense before the Strategic Forces Subcommittee of the Senate Armed Services Committee, General Greaves reaffirmed the success of the test.  Asked by Senator Angus King whether the test was a success, General Greaves stated that although there were nine months of data to review, the “initial look says it was a complete success.”

Senator King then asked him to “Define complete success, did the bullet hit the bullet?”

After giving some background information on testing, General Greaves stated:

“But this test was different because we launched within a very short period of time two Ground-Based Interceptors operationally released by the combatant commander using their operational processes –which is very important — and the lead interceptor intercepted the ICBM-representative threat.  But what’s most important is that it created a debris field — and this test has been 10 years or more in the making — and the importance of that was the trailing — the second — interceptor was able to discern the debris from the next most lethal object — I can talk about it in a classified forum — and also intercepted that object. What that means is [an] enemy concept of operations which seeks to confuse our missile defense system by launching junk or debris would not be successful, that’s why it was a success.” [My transcription from the video of the hearing.]

 Both the press release and the General Greaves quote immediately above make it clear that after the first intercept, there remained both debris and at least one other object.  All of these other objects must have had an appearance sufficiently different from the warhead so that the first interceptor could select the warhead.  And at least one of these other objects must have had an appearance sufficiently different from the debris so that the second interceptor could identify it.

So although when Senator Dan Sullivan asked General Greaves if the second interceptor had hit the largest debris fragment, General Greaves replied “Yes, sir,” he immediately clarified this saying that it hit “the next most lethal object” which he defined as ‘the next object that most closely resembles a threat vehicle.”

But what did FTG-15 actually prove?  Did it provide “evidence of the practicable use of the salvo doctrine” as the press release claimed?  Did it demonstrate that such the salvo doctrine would defeat enemy attempts to confuse the system as General Greaves quote suggests? I think it is clear the answer to both questions is “No.”

Strictly speaking, the test did demonstrate that the GMD system could intercept a target resembling a warhead against a field of debris, none of which resembles a warhead.  But why would any enemy try to defeat the system with such an obviously ineffective tactic (unless the warhead was disguised to look like debris)?  Moreover, the debris field that an attacker might deploy along with its warhead likely would look quite different than the debris field produced by an interceptor hitting a warhead or other object.  Finally, there was no need to launch two interceptors to conduct this demonstration.  Debris could have been launched along with the first warhead, and there would have been no need to waste a second $70 million GBI interceptor.

More importantly, the fundamental purpose of the salvo firing doctrine is to compensate for low missile defense system reliability, the interceptor reliability in particular.  For example, if the GBIs were believed to be 60% reliable (although this is slightly higher than its success rate in intercept tests – see table at end of this post — there is not enough test data to know their what actual reliability is), then salvo firing N interceptors gives a probability of killing the target of PKN = 1 – (1-0.6)N.   So for one interceptor PK1 = 0.6, for a two-interceptor salvo PK2 = 0.86, and for a three interceptor salvo PK3 = 0.936.  This is why many observers of the GMD system have speculated that the GMD firing doctrine is at least a three or four interceptor salvo against a single attacking missile.  This assumes that the failure of any one interceptor is statistically independent of the others.

A two interceptor salvo firing doctrine benefits the defense against an attacking missile when the first interceptor fails.  There is no benefit from the second interceptor if the first interceptor destroys the target, as was the case in FTG-11. 

More importantly, when an attacker takes deliberate and effective steps to defeat the defense (countermeasures), the salvo doctrine will be much less effective.  This is because if a countermeasure (and not an interceptor reliability problem) causes the first interceptor to fail, then there is a substantial probability that the countermeasure will also cause subsequent interceptors to fail.  For example, consider a case in which the warhead is disguised to look like a decoy and is accompanied by five credible light-weight decoys.  If the interceptor is unable to distinguish between the disguised warhead and the decoys, it will have to choose one of six potential targets.  Assuming  the interceptor has a same reliability as assumed above, 0.6, the chance of a successful intercept of the warhead with a single interceptor  is only PK1 = 0.6 * (1/6)  = 0.10. In a salvo of two interceptors, if the first interceptor fails to destroy the warhead, the odds for the second one are slightly better, because there is an 60% chance it will see only five targets, so the kill probability for this interceptor is P­K1­ = 0.6*0.6*(1/5) + 0.4*0.6*(1/6) = 0.112, and the overall success rate for the two intercept salvo is only PK2 = 0.201.  The salvo firing doctrine does not solve the countermeasure problem, which has long been recognized as the most important and difficult problem facing an above-the-atmosphere defense such as the GMD system

It is worth noting that FTG-11 was not MDA’s first attempt to intercept a target against a debris field.  On November 1 2015, MDA conducted test FTO-02 event 2.  In this test, a short range ballistic missile target was successfully intercepted by a THAAD interceptor, creating a debris field.  An Aegis SM-3 Block IB TU interceptor then attempted to intercept a medium-range ballistic missile against the background of this debris field.  However, the SM-3 missile failed before it could make the intercept attempt.  The target was then destroyed by a second THAAD interceptor, although it is unclear (to me) if the target was still in the vicinity of the debris field.  However, even prior to FTO-02, MDA had conducted “tests to verify interceptor performance in debris clouds” although these most likely were of systems such as the Aegis SM-3 or THAAD and involved only a single interceptor.

I think FTG-11 is better regarded as two separate intercept tests, albeit separated by less than a minute.  I have accordingly updated my Tables of Intercept Tests post of November 30, 2018, counting both tests as successes.  The GMD table from that post is below:

Estimating the Range of the Long Range Discrimination Radar (April 2, 2019)

In my post of February 11 2019, I discuss what is publicly known about the Long-Range Discrimination Radar (LRDR) now under construction in central Alaska and the closely related Homeland Defense Radars (HDRs) to be built in the Pacific. The post also discussed the new SPY-6 radar to be deployed on new construction U.S. Navy Aegis destroyers starting in about 2023 and the Lockheed Martin Solid State Radar (SSR) to be used in the planned Japanese Aegis Ashore missile defense facilities.

In this post, I attempt to make some estimates about the LRDR’s capabilities, and, by extension, those of the HDRs. This requires making some speculative, although I think reasonable, assumptions.

Only a few technical details are known about the LRDR. It has two antenna faces. Artist renderings of the LRDR suggest that the boresites of the two faces are separated by about 120°, which is consistent with the reported requirement that the LRDR must have a “wide instantaneous field of view to enable wide area defense”(see my post of January 30, 2019).  It is known that the LRDR operates in S-Band, which extends from 2 GHz to 4 GHz. S-Band was chosen over X-Band, which offers superior discrimination capabilities, largely due to cost considerations. It likely has an antenna area of about 280-300 m2 per antenna face.  For convenience, I repeat the part of my February 11 2018 post on which this conclusion about the antenna is based:

“A 2017 article stated that the LRDR will have two 3,000 square-foot antenna arrays (3,000 sq-ft = 279 m2).[1]  According to Chandra Marshall, Lockheed’s LRDR program manager, the LRDR will be about 25 times larger than a SPY-1 antenna.[2] Assuming this comparison applies to each face of the radars, since a SPY-1 antenna face has an aperture of about 12 m2, this gives an aperture of about 300 m2 for the LRDR.”

Based on this information, what can we deduce about the LRDR’s capabilities?  First, I’ll assume the smaller of the of the two antenna areas above, A = 280m2.  Assuming a square antenna, as suggested by the renderings in my February 11 post (the drawing in the January 30 post suggests a circular antenna, but this is likely an older rendering), then the antenna would be D = 16.7 m square.  Assuming that the LRDR operates at a wavelength of about λ = 8.6 cm, corresponding to a frequency of about 3.5 GHz (for comparison, the current Aegis SPY-1 radar operates at 3.1-3.5 GHz), gives an approximate beamwidth of θ ≈ λ/D = 16.7/0.086 = 0.0051 rad = 0.29°.  This gives a beamwidth of about 20 km at a range of 4,000 km.  The gain G of the antenna, assuming it is fully populated with T/R modules, is given by G = 4πA/λ2 = 480,000.

To try to get a rough estimate of the LRDR’s tracking range, I start with a basic form of the radar equation:

RadarEq04022019

Rmax = maximum radar range (m),

ρ = antenna aperture efficiency,

Pav = radar average power (W),

A = antenna area (m2),

G = antenna gain,

td = beam dwell time,

σ = radar cross section of target (m2),

k = Boltzmann’s constant (1.38×10-23 J/K),

T0 = 290 K, FN = receiver noise figure,

(S/N) = signal-to noise ratio required for detection,

LS = system losses.

The problem here is that we do not know the value of many of the quantities in the radar equation, most notably Pav. One possible way around this problem is to compare the LRDR to another radar using similar technology but for which more information is available. The obvious choice here is the Aegis SPY-6.

Both the LRDR and the SPY-6 are active array radars using GaN Transmit/Receive (T/R) modules and both operate in S-Band. Both radars are state-of-the-art in their use of new GaN technology. Raytheon (the maker of the SPY-6) competed with Lockheed Martin for the LRDR, HDR-H and the Japanese Aegis Ashore SSR and won each of these contracts. This suggests that the radar technology used in the LRDR is at least comparable with that used in the SPY-6. So I will assume both radars operate at the same frequency (wavelength), will take ρ/FNLS to be the same for both radars and assume that the T/R modules in each radar have the same average power.

Since both radars operate in S-Band, it is reasonable to assume that the target radar cross section will be the same for both radars. If we then operate both radars using the same dwell time and require the same S/N for tracking, we get:

L4/R64 ≈ PLALGL/P6A6G6,

where the subscript “L” denotes the LRDR and the subscript “6” denotes the SPY-6, and the P is average power. If both radars have the same spacing between modules[3], then the average power per antenna face will be proportional to the antenna area, and since G = 4πA/λ2, we get:

L4/R64 = AL3/A63.

Using 280 m2 for the LRDR antenna area and taking the antenna area for one face of the SPY-6 to be 13.8 m2 (as discussed in my February 11 post), we get:

RL4/R64 ≈ AL3/A63 = 2803/13.83 = 20.33 = 8,370 and RL ≈ 9.6R6.

Thus if the LRDR and SPY-6 were operated in the same way and against the same target, the detection and tracking ranges for the LRDR will be about 9.6 times that of the SPY-6.  In actual practice, the LRDR will likely be operated in a way that will give an even greater range advantage.

However, this still does not give us a numerical range for the LRDR because we don’t know the range of the SPY-6.  However, we do know that the SPY-6 is expected to be at least 15dB ≈ 31.6 times more sensitive than the current Aegis SPY-1radar (see my February 11 2019 post). If the subscript “1” denotes the SPY-1, then we have:

RL4/R14 ≈ 8,370*31.6 = 264,000 and RL ≈ 22.7R1.

My post (along with Theodore Postol) of October 23, 2012 notes the claim that the SPY-1 “can track golf ball-sized targets at ranges in excess of 165 kilometers.”[4]  This claim was not made in the context of ballistic missile defense, but rather for air targets.  A golf ball-size (1.68 inches diameter) metallic sphere corresponds to radar cross section (RCS) of about 0.0025 m2 at 3.3 GHz.  Scaling this to a RCS of 0.03 m2 (for a missile target at S-Band) gives a range in excess of 310 km. Since the Aegis radar must be continually scanning the sky for incoming threats, this range is likely based on a relatively short dwell time.  Using a relatively long dwell time of 0.1 second and S/N = 20 for detection and tracking, we obtained a range of 550 km.  Using these two figures as rough lower and upper bounds on the Aegis radar range, gives upper and lower range estimates for the LRDR of 7,000 to 12,500 km.”

In a missile defense context, such large tracking ranges are not usually obtainable, because at ranges greater than about 4,000 km missile targets on minimum energy trajectories will not rise above the horizon.  However, even using the 7,000 km lower-bound range figure, the LRDR would be able to obtain a S/N on a 0.03 m2 target of nearly 200 at a range of 4,000 km.  Obviously, at shorter ranges the S/N would be much greater.

A high S/N ratio can also be essential for constructing a target object map (TOM) that allows a scene (threat cloud) viewed by a radar to be translated into the scene that would be seen by an infrared-homing kill vehicle.  For a brief discussion of this issue, see Countermeasures, pp. 77-79.[5]

As described by the 2012 National Academy of Sciences report:

“With adequate signal-to-noise ratio, a monopulse tracking radar can limit measurement error to less than 1 percent of its beamwidth. Over extended track periods, the relative positions can be refined by a further order of magnitude.  Along with measurement of relative range to a fraction of a meter, using wideband waveforms, these position data provide a three-dimensional target object map that can be converted to the angular coordinates of a homing seeker, ensuring proper registration of each object in the target cluster.”[6]

However, measuring an angular position to 1 percent of a beamwidth with a monopulse radar requires a very large S/N ratio. For a square antenna with sides D, the angular measurement error is given by:[7]

Δθ = 0.5 (S/N)-0.5 (λ/D)

Since λ/D is the approximate beamwidth, achieving an angular measurement of 1 percent of the beamwidth requires S/N ≈ 2,500.

For the lower-bound and upper-bound estimates above, a S/N of 2,500 would be achieved at ranges of about 2,100 and 3,700 km respectively.

What does the above say about the Homeland Defense Radars (HDRs)?  These are often described as scaled-down versions of the LRDR.  For example, the HDR-H, to be built in Hawaii, fills a role previously proposed for a radar that was to be called the Medium Range Discrimination Radar.  However, the projected costs of the HDRs strongly suggest that they are not much smaller than the LRDR. As discussed in my post of February 11, the HDR-H is expected to cost about $1.0 billion, about 77% of $1.3 billion cost of the LRDR.  However, the LRDR will have two radar faces, while the HDR-H will have only one.  This factor alone could account for the cost difference.

The HDR-P, on the other hand, will have two radar faces and is projected to cost the same $1.3 billion as the LRDR.  It thus seems likely to be similar in scale to the LRDR.  As discussed in my post of February 11, although the United States has not announced where the HDR+P will be built, Japanese media reports indicate that it will be built in Japan.  A two-faced HDR built in northern Japan would be able to look deep into both China and eastern Russia, and would undoubtedly encounter strong opposition from both countries.

A December 2018 Government Accountability Office report stated that: “According to DOD officials, the department may no longer need Cobra Dane to meet the ballistic missile defense mission after MDA fields a new radar in the Pacific region in fiscal year 2025,” but that it would continue to operate Cobra Dane until it was replaced with a system with greater or equal capabilities.[8] (The date for the Pacific radar has since slipped to 2026.)  The same report also stated that there would be no radar tracking coverage gap (between the TPY-2s in Japan, the Cobra Dane on Shemya Island, and the LRDR in central Alaska) once the LRDR was deployed for North Korean missiles fired towards the continental United States.  However, since the Cobra Dane is not capable of discrimination, there would be a discrimination gap for North Korean missiles launched towards the eastern United States.  In addition, once the Cobra Dane is retired (current plans call for operating it until at least 2030) there would be a tracking gap as well.

The deployment of a two-faced HDR-P in either Japan or Shemya would close both of these gaps.

Upcoming MDA flight and Intercept Tests (March 27, 2019)(Revised)

Now that the Missile Defense Agency (MDA) budget materials are available, I have compiled a list of MDA’s planned flight tests and intercept tests out through 2024 (there is one test listed for 1Q FY2025).   These tests are listed in the two tables below, along with whatever other information about each test that I have been able to find (and sometimes some speculation). (Revision: at the end of the post I have repeated both tables in an easier to read (I think) format)

Two points about these tables:

(1) In the past several years, there have been very few Patriot tests listed, presumably because most of these tests are conducted by the U.S. Army, not by the MDA (except for Patriots participating in integrated intercept tests). This year, however, there are 13 Patriot flight or intercept tests listed.  All of the ones in FY 2020, and likely all of them except for the one in the integrated test FTO-03, appear to be associated with a U.S. Forces Korea (USFK) Joint Emergent Operational Need (JEON) Statement.  JEON is focused on near term improvements to U.S. missile defense in South Korea and the program was assigned to MDA, together with the U.S. Army’s Lower Tier Program Office (LTPO).  According the MDA’s FY 2020 Budget Overview: “Finally MDA continues development efforts associated with USFK JEON that provides enhanced THAAD capability against specific USFK threats, integrates THAAD’s capability to detect and track threat ballistic missiles at long ranges [for use] with the Patriot Advanced Capability – 3 Missile Segment Enhancement (PAC-3 MSE) to take advantage of its full kinematic capability, integrate MSE launchers and missiles into the THAAD weapon system, and accelerates initial capability to [use] remote launchers and increase defended area.”  With the exception of FTO-03, I have put all the Patriot tests into a separate Table 2.

(2) The budget materials show one “Israeli Cooperative Intercept Flight Test” per year from FY 2019 to FY 2024. However, each of these “tests” span an entire year, and each is apparently a series of tests rather than a single test.  The FY 2020 MDA Budget Overview says:  “In FY 2020, the MDA budget will also support several flight tests across the Israeli portfolio.”  Since I cannot (yet, at least) associate tests with particular dates and systems, I have not included these in the tables.

Aegis SPY-1 Radar Upgrade (March 25, 2019)

The Navy plans to equip its new Flight III Aegis destroyers with its new SPY-6 radar.  The SPY-6 is made up of 37 self-contained Radar Module Assemblies (RMAs).  The SPY-6 is expected be at least 30 times more sensitive than the current Aegis SPY-1D radar (or 2.3 times the detection or tracking range against a given target).

A reader of my March 13 post noted that in the FY 2020 budget the Navy announced plans to upgrade the SPY-1D Aegis radar on its Flight IIA destroyers by replacing the current antennas and transmitters with a 24 RMA antenna, and asked how this upgraded radar would compare to the current SPY-1D radar and the new SPY-6.

Since the SPY-6 and the planned upgrade to the SPY-D will use the same radar technology, they will primarily differ only in their power, antenna area and gain.  Since each of these is proportional to the number of RMAs, the upgraded SPY-1 radar will have (24/37)3 = 0.27 of the sensitivity of the SPY-6.  However, it will have about (0.27)(30) = 8 times the sensitivity of the current SPY-1D (which is a pretty big improvement).

GMD Testing Update (March 19, 2019)

The FY 2020 RDT&E budget documentation for the Missile Defense Agency is now out, and unlike the previous year’s materials it includes currently planned quarterly dates for flight and intercept tests of the Ground Based Midcourse (GMD) system.  Through 2024 it appears that there are three intercept tests and two (non-intercept) flight tests planned.  Here they are:

The testing schedule for the RKV shows a slip of about two years.   This is consistent with the two year delay (from 2023 to 2025) in RKV deployment that was announced at the March 12 MDA press briefing on its FY 2020 budget.

 

 

MDA Briefing on FY 2020 Budget (March 13, 2019)(Updated March 14)

The Missile Defense Agency (MDA) presented their proposed budget for FY 2019 yesterday.  Although there is not yet any information about the budget posted on their website, a video of the briefing was posted today. I have put the slides shown at the briefing into a Word file, which is here: MDA-Budget_Briefing-Slides-03122019

(The first slide was not shown on the video, but it is probably just a title slide as there was no discussion of it.)

I expect that a transcript of the briefing will be available soon.  If so, I will add a link to it.

[Added March 14: The transcript is here.]

The two most interesting (to me) things I learned in the briefing:

(1) The RKV is delayed.  The development and deployment of Redesigned Kill Vehicle, intended to be more reliable than the current kill vehicles deployed on the Ground-Based Interceptors (GBIs) of the current U.S. national missile defense system, has been delayed by two years, from 2023 to 2025.  Since the RKVs were to be deployed on the 20 additional GBIs (bringing the total to 64) that were scheduled to begin deployment in Alaska in 2023, the beginning of the deployment of these additional GBIs has also delayed by two years from 2023 to 2025.

(2) The Neutral Particle Beam is back.  Much discussed during the “Star Wars” days, the state of technology at the time ultimately was shown to be far from allowing an actual neutral particle beam weapon to be built. However, in FY 2020 MDA plans to initiate a new program to develop a neutral particle beam that will “offer new kill options.”  MDA claims that this program could lead to an on-orbit demonstration as early as 2023.

New S-Band Missile Defense Radars in the Pacific (February 11 2019)

The United States is in the process of building (or selling) a number of new missile defense radars focused on coverage over eastern Asia and the Pacific Ocean.  All of these radars will operate in S-Band, which extend from 2 to 4 GHz.  These radars are the Long Range Discrimination Radar (LRDR), the Homeland Defense Radar – Hawaii (HDR-H), the Homeland Defense Radar – Pacific (HDR-P), and the Lockheed Martin Solid State Radars (SSRs) that Japan intends to buy for its two planned Aegis Ashore facilities. Most if not all of these phased-array radars will be built by Lockheed Martin using relatively new Gallium Nitride (GaN) technology.  There is little publicly available information about these radars, so there will not be much in the way of technical details in this post.  This post will also include an update on Raytheon’s new S-Band Air and Missile Defense Radar (AMDR).

The Long Range Discrimination Radar (LRDR)

A previous post discusses the LRDR up until April 2015.  This discussion picks up where that one left off.

In October 2015, the Missile Defense Agency (MDA) awarded Lockheed Martin a $784 million contract to develop, test and build the LRDR.[1]  The objective was to have the LRDR operational at Clear Air Force Station in central Alaska by 2020.  Military construction costs (including a shielded mission control facility, shielded power plant, radar foundation and a maintenance facility) will add another $329 million, bringing the total cost of building the LRDR to over $1.1 billion.[2]  However, it is typically described in the press as a $1.2 billion project.  Construction of the LRDR in Alaska began in September 2017.[3] As of March 2018, “initial fielding” of the LRDR was expected in 2020 with “operational readiness acceptance by the warfighter in the 2022 timeframe.”[4]
