Initially designated as the YCH-1B, on 21 September 1961, the preproduction rotorcraft performed its maiden flight. Marine Corps as the CH-46 Sea Knight, the Army sought a heavier transport helicopter, and ordered an enlarged derivative of the V-107 with the Vertol designation Model 114. While the YHC-1A would be improved and adopted by the U.S. Army ordered a small number of V-107s from Vertol under the YHC-1A designation following testing, it came to be considered by some Army officials to be too heavy for the assault missions and too light for transport purposes. 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 helicopter. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Its name, Chinook, is from the Native American Chinook people of Oregon and Washington state. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. The Boeing CH-47 Chinook is a tandem-rotor helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol.
