Fleet composed of 14 satellites. USAF asked LM [in mid-1995] for a cost
estimate on upgrades to the remaining ground-spare DSCS-3s to extend their
lives somewhat: improved thrusters, better solar cells, more efficient
amplifiers in the high-power channels. The DSCS-3 production line shut down
several years ago, and the USAF wants to postpone the start of development on
DSCS-4 to 2010. Meanwhile the
should fill the gap.
The lifetime of the satellite is generally exceeded as the fuel saving
procedures are efficient.
