SDS-2
Part of HS 381 / HS 386 Family
American military communications satellite. Comsat / Relay satellite built by Hughes for USAF, USA. Launched 1989 - 1996. Used the HS-386 bus.

AKA: SDS. Status: Operational 1996. First Launch: 1996-05-12. Last Launch: 1996-05-12. Number: 1 . Gross mass: 6,000 kg (13,200 lb).

Replacement for the SDS satellites, which from Molniya-type orbits, provided data relay services for optical reconnaissance and other military spacecraft. They were launched by the Shuttle/IUS or by the Titan IV, which implies a satellite mass of around 6000 kg, compared to only 700 kg for the earlier SDS satellites. They therefore probably included other reconnaissance payloads as well (signals intelligence, early warning, weather monitoring, etc).
