INTELSAT 6 F-3 was launched from Cape Canaveral, Florida using a Titan 3 booster rocket. A booster separation failure cast INTELSAT 6 F-3, the second in the series, into a non-operational substationary orbit. The satellite carried 38 C-band and 10 K-band transponders, to provide telephone, TV and data services to large ground stations and small terminals. It could have accommodated 120,000 phone calls and 3 TV channels simultaneously. Built by Hughes Space and Communications Group for INTELSAT, the new series satellite were the largest commsats flown to date. It was drum-shaped, 3.6 m in diameter and 11.7 m tall, weighing 4,215 kg at launch; 2,560 kg on orbit. Body mounted solar arrays provided 2,250 W at end of life.
