Design

The seventh of eight Intelsat III satellites to be launched, Intelsat III F-7 was built by TRW. It was a 647-kilogram (1,426 lb) spacecraft equipped with two transponders to be powered by body-mounted solar cells generating 183 watts of power. [3] It had a design life of five years and carried an SVM-2 apogee motor for propulsion.

Launch

Intelsat III F-7 was launched by a Delta M rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station.
