The Boeing Vertol XCH-62 (Model 301) was a triple-turbine, heavy-lift helicopter project designed for the United States Army by Boeing Vertol. Approved in 1971, one prototype reached 95% completion before it was canceled in 1975.

The XCH-62 prototype was a tandem-rotor helicopter powered by three Allison XT701-AD-700 turboshafts, rated at 8000hp each. The diameter of each four-bladed rotor was 28 metres (92 feet).

Boeing Vertol XCH-62 HLH The US Army Heavy Lift Helicopter or HLH specification was approved in May 1971 for a 22 tonnes payload class helicopter in an attempt to match the top russian models: the Mi-26 and the much bigger Mi-12.

The XCH-62 was built for the US Army's HLH (Heavy Lift Helicopter) specification. This 'flying crane' stood 11.8m high and the fuselage was 27m long. It could carry loads of up to 20 tonnes (20,000 kg) slung below the fuselage.

XCH-62 Serial Number 73-22012, built by Boeing-Vertol in Philadelphia and destroyed by a goon in a payloader thirty years later, turns out to have been something less than a real helicopter.

The XCH-62 is a tandem-rotor, shaft-driven, heavy-lift helicopter. The XCH-62, an HLH under development at the time, was viewed strictly as a "flying truck" to be used only over...

A phased research program plan was prepared, which envisioned progressing to assembly of the finished prototype vehicle and proceeding to flight test to validate the technology advances embodied in the XCH-62 design.

The Boeing Vertol XCH-62 was a prototype heavy-lift helicopter which never really took off. Either figuratively or literally. It was designed for the US Army in the early '70s.

Constructed as a XCH-62. Only partly constructed before contract was cancelled. Taken on Strength/Charge with the United States Army with s/n 73-22012. While a serial number was assigned, the aircraft was not taken on strength, since the Army cancelled the contract. Incomplete aircraft was stored at Vertol in Pennsylvania.
