Initial development<\/h3>\n\n\n\n

During late 1956, the U.S. Department of the Army announced its intention to replace the Sikorsky CH-37 Mojave<\/a>, which was powered by piston engines<\/a>, with a new, gas turbine-powered<\/a> helicopter.[2]<\/a><\/sup> Turbine engines were also a key design feature of the smaller UH-1 “Huey”<\/a> utility helicopter. Following a design competition, in September 1958, a joint Army\u2013Air Force source selection board recommended that the Army procure the Vertol-built medium-transport helicopter. Funding for full-scale development was not then available, though, and the Army vacillated on its design requirements. Some officials in Army Aviation<\/a> thought that the new helicopter should be operated as a light tactical transport aimed at taking over the missions of the old piston-engined Piasecki H-21<\/a> and Sikorsky H-34<\/a> helicopters, and be consequently capable of carrying about 15 troops (one squad<\/a>). Another faction in Army Aviation thought that the new helicopter should be much larger, enabling it to airlift<\/a> large artillery<\/a> pieces and possess enough internal space to carry the new MGM-31 “Pershing” missile system<\/a>.[2]<\/a><\/sup><\/p>\n\n\n\n

During 1957, Vertol commenced work upon a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107.[3]<\/a><\/sup>[4]<\/a><\/sup> During June 1958, the U.S. Army awarded a contract to Vertol for the acquisition of a small number of the rotorcraft, giving it the YHC-1A<\/em> designation.[5]<\/a><\/sup> As ordered, the YHC-1A possessed the capacity to carry a maximum of 20 troops.[2]<\/a><\/sup> Three underwent testing by the Army for deriving engineering and operational data. However, the YHC-1A was considered by many figures within the Army users to be too heavy for the assault role, while too light for the more general transport role.[2]<\/a><\/sup> Accordingly, a decision was made to procure a heavier transport helicopter, and at the same time, upgrade the UH-1 “Huey” to serve as the needed tactical troop transport. The YHC-1A would be improved and adopted by the Marines as the CH-46 Sea Knight<\/a> in 1962.[6]<\/a><\/sup> As a result, the Army issued a new order to Vertol for an enlarged derivative of the V-107, known by internal company designation as the Model 114, which it gave the designation of HC-1B.[7]<\/a><\/sup> On 21 September 1961, the preproduction Boeing Vertol<\/a> YHC-1B made its initial hovering flight. During 1962, the HC-1B was redesignated the CH-47A under the 1962 United States Tri-Service aircraft designation system<\/a>; it was also named “Chinook” after the Chinook people of the Pacific Northwest<\/p>\n\n\n\n
