A Three-Stage Two-Stage GBI Interceptor (February 2, 2016)

One thing that was surprising (to me, at least) about Missile Defense Agency (MDA) Director Admiral James Syring’s January 19 2016 presentation at the Center for Strategic and International Studies was his description of the MDA’s planned two-stage version of the Ground-Based Interceptor (GBI).[1]

The MDA has long had plans to eventually incorporate a two-stage version of the three-stage GBI currently deployed in Alaska and California into its Ground Based Midcourse GMD) national missile defense system.

The idea of using a two-stage version of the GBI first came to public attention in 2006 when the George W. Bush Administration announced plans to deploy two-stage GBIs in Europe to provide an extra layer of defense of U.S. territory against Iranian ICBMs.  Although an agreement was reached in 2008 to deploy ten of the two-stage GBIs on Polish territory, in 2009 President Obama cancelled these plans in order to proceed with his European Phased Adaptive Approach (EPAA).  However, the possibility of deploying two-stage GBIs – this time on U.S. territory — was retained was retained as part of the GMD “hedge” strategy.[2]
