Summary
USA 170 (also known as DSCS III B-6) is a communication satellite with a configuration of DSCS-3 Bus and uses 3-axis stabilization. It was launched by the United States on August 29, 2003, from SLC37B at AFETR using a Delta 4M launch vehicle. The spacecraft has dimensions of 2.1 meters in length, 1.9 meters in diameter, and a span of 9.5 meters. It had a launch mass of 1244 kg and a dry mass of 900 kg. Equipped with 6 SHF transponders and one special purpose transponder capable of operating on both SHF and UHF frequencies, the satellite is powered by two deployable solar arrays and batteries. Its mission is communication support for AFSMC/DISA, and it has a designed lifetime of 10 years. The shape of the satellite is described as "Box + 2 Pan," with its attitude control provided by an AOCS system. It was manufactured by LMVF.
