Intelsat V F-4 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network.
The arrays, supplemented by nickel-hydrogen batteries during eclipse, provided 1800 watts of power.
It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously.
