According to the Missile Defense Agency, the Jan. 31 major test of the Ground-based Midcourse Defense System, in which an interceptor fired from Vandenberg AFB, Calif., was to intercept a ballistic missile target launched from the Kwajalein Atoll in the Pacific, “did not perform as expected” because of a problem with the Sea-based X-band radar portion of the system. Both the interceptor and target vehicle launched successfully but there was no intercept. According to an MDA release, program officials plan “an extensive investigation” to find the cause.
The Space Development Agency added 21 satellites to its nascent data transport network in an Oct. 15 launch, the second mission in a 10-month campaign to field 154 operational spacecraft.
