Summary
OPS 9443 (DSCS 2-13), also known as DSCS II F-13, is a US communication satellite launched on November 21, 1979, from Launch Complex 40 at AFETR using the Titan IIIC launch vehicle. It has dimensions of 3.6 meters in length and 2.7 meters in diameter with a span of 3.6 meters. The spacecraft weighs 550 kilograms dry and had an initial mass of 610 kilograms at launch. Equipped with spin-stabilization technology and despun antennas, it carries two X-Band transponders for communication purposes. The satellite is powered by solar cells and batteries and was manufactured by TRW for the Air Force Space Systems Division (AFSD/DCA). Its primary mission was to provide communication services, with a designed lifetime of 5 years.
