This post is an attempt at a graphical depiction of the GMD testing schedule. Information on future tests is as complete as the information I can find, but is certainly incomplete. I will update this as I get more information. Click on the images to make them more readable.
Each row of the table shows the tests that have taken place at that time and projected future tests. The first three rows are for mid-2009, mid-2010, and mid 2011, respectively. The fourth row is current as of about March 2012.
Future tests for mid-2008 row from: Victoria Sampson, “Flight Test for Ground Based Midcourse (GMD) System, Center for Defense Information, December 22, 2008 (Available at: http://www.cdi.org/pdfs/GMD%20IFT3.pdf). Also see this for information on earlier tests of non-operationally-configured interceptors.
The mid-1010 and mid-2011 tests are largely drawn from : Briefings at MDA GMD DSC Media Week Briefings, March 2010 (available at: http://www.mda.mil/global/documents/pdf/GMD_DSC_presentations.pdf); Lt. Gen. Patrick O’Reilly, “Ballistic Missile Defense Overview — Phased Adaptive Approach,” Briefing Slides, 2011 Space and Missile Defense Conference, August 17, 2011 (available at: http://www.mda.mil/global/documents/pdf/bmds_briefing11_2.pdf ); and Director, Operational Test and Evaluation, “Ground-Based Midcourse Defense (GMD),” 2011 Annual Report (available at: http://www.dote.osd.mil/pub/reports/FY2011/).
