An updated description of planned GMD flight tests (last update was my post of April 12, 2015) as best I can reconstruct them. Between now and mid-2021, it appears that MDA plans five intercept and one non-intercept test of the GMD system.
FY 2017:
FTG-15 (1Q FY 2017). This is scheduled to be the first intercept test since FTG-06b in June 2014. It will be the first GMD intercept test against an ICBM-range target (range greater than 5,500 km). The target will include countermeasures. FTG-15 will also will be the first flight and intercept test of the new production CE-II Block-I version of the Exo-Atmospheric Kill Vehicle (EKV) and the first flight test of the upgraded C2 booster. According to Admiral Syring, in this test “…we’re getting now out to the long-range and closing velocities that certainly would be applicable from a North Korean or Iran type of scenario.” [1]
