Description : Westar 5 satellite carries 24 channels develops forty percent more transmitting power than preceding domestic comsats and produces more than eight hundred watts of solar power.
When Western Union returned to Hughes Aircraft Company in 1980 for a second generation of Westar satellites, it selected spacecraft having twice the capacity of their predecessors.

Hughes’ Space and Communications Group built three Hughes HS-376 model satellites, designated Westar 4, 5, and 6, for Western Union Telegraph Company. These new spacecraft stand 21.6 feet tall in operation and carry 24 C-band transponders, each of which can accommodate 2400 telephone calls or one color TV channel.

Westars 4 and 5 were launched on McDonnell Douglas Delta boosters from Cape Canaveral, Fla.
