Sikorsky S-73
The Sikorsky S-73 was a proposed aircraft design to meet the United States Army requirement in 1970 for a Heavy Lift Helicopter (HLH) capable of carrying 45,000 lb (20,000 kg; 20 t), a lifting capacity more than twice that of Sikorsky's most powerful helicopter at that time. Sikorsky submitted their design in February 1971, then in May the Army declared the Boeing Vertol XCH-62 winner of the contract, ending the Sikorsky S-73 program.
