Evidence: 100 • authority: 72

The CH-53 Sea Stallion (Sikorsky S-65) is a family of American heavy-lift transport helicopters designed and built by the American manufacturer Sikorsky Aircraft. The Sea Stallion was developed in response to a March 1962 request from the United States Navy's Bureau of Naval Weapons for a replacement for the Sikorsky CH-37 Mojave helicopters flown by the United States Marine Corps (USMC). In July 1962, Sikorsky's proposal, which was essentially a scaled-up S-61R fitted with twin General Electric T64 turboshaft engines and the dynamic systems of the S-64/CH-54, was selected. On 14 October 1964, the YCH-53A performed its maiden flight; the first deliveries of production CH-53s to operational…

The Boeing Vertol CH-46 Sea Knight is an American medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing. Development of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. It was envisioned as a successor to the first generation of rotorcraft, such as the H-21 "Flying Banana", that had been powered by piston engines; in its place, the V-107 made use of the emergent turboshaft engine. On 22 April 1958, the V-107 prototype performed its maiden flight. During June 1958, the US Army awarded a contract for the con…

The Sikorsky CH-53K King Stallion (Sikorsky S-95) is a heavy-transport helicopter designed and produced by Sikorsky Aircraft. The King Stallion is an evolution of the long-running CH-53 series of helicopters that has been in continuous service since 1966, and features three up-rated 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than its predecessors. It is the largest and heaviest helicopter in the U.S. military. The United States Marine Corps made plans to receive 200 helicopters at a total cost of $25 billion. Ground-test vehicle testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018, the first CH-5…

The Sikorsky CH-37 Mojave (company designation S-56) is an American large heavy-lift military helicopter of the 1950s. It entered service as the HR2S-1 Deuce with the USMC in 1956, and as the H-37A Mojave with the U.S. Army that same year. In the early 1960s, the designation was standardized to CH-37 for both services, with the HR2S-1 redesignated as CH-37C specifically. Developed in the early 1950s, with its first flight in 1953, it filled a 1950 Navy requirement for an assault helicopter that could carry up to 20 Marines and haul combat equipment. The design includes a front-loading ramp with side opening clam shell doors on the nose. It was powered by two radial piston engines. It served…

The Boeing CH-47 Chinook is a tandem-rotor helicopter originally developed by American rotorcraft company Vertol and now manufactured by Boeing Defense, Space & Security. The Chinook is the second-heaviest-lifting Western heavy-lift helicopter, behind the Sikorsky CH-53. Its name comes from the Chinook people, who are indigenous to the Pacific Northwest of the United States. The Chinook was designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the piston-engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered…
