Intelsat V-D (F-4) was a communications satellite operated by COMSAT. Launched in 1982, it was the fourth of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat V satellite bus. 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. The payload housed 21 C-band and 4 Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It had a launch mass of 1928 kg. The satellite was deactivated in November 1995.
