The fifth of eight Intelsat III satellites to be launched, Intelsat III F-5 was built by TRW. It was a 293-kilogram (646 lb) spacecraft equipped with two transponders to be powered by body-mounted solar cells generating 183 watts of power. It had a design life of five years and carried an SVM-2 apogee motor for propulsion.
Intelsat III F-5 was launched by a Delta M rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch took place on July 26, 1969, with the spacecraft bound for a geosynchronous transfer orbit.
Due to a failure in the third phase of the launch process, the satellite did not reach the desired orbit.
