The Boeing CH-47 Chinook is an American twin-engine, tandem-rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later known as Boeing Rotorcraft Systems). The CH-47 is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of modern-day Washington state.

 

The Chinook was originally designed by Vertol, who had begun work in 1957 upon 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 helicopter. During June 1958, 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. While the YHC-1A would be improved and adopted by the U.S. 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. Initially designated as the YCH-1B, on 21 September 1961, the preproduction rotorcraft performed its maiden flight. In 1962, the HC-1B was re-designated CH-47A under the 1962 United States Tri-Service aircraft designation system.

The CH-47D shares the same airframe as earlier models, the main difference being the adoption of more powerful engines. Early CH-47Ds were originally powered by two T55-L-712 engines, the most common engine is the later T55-GA-714A. With its triple-hook cargo system, the CH-47D can carry heavy payloads internally and up to 26,000 pounds (12 t) (such as 40-foot or 12-metre containers) externally. It was first introduced into service in 1979. In air assault operations, it often serves as the principal mover of the 155 mm M198 howitzer, accompanying 30 rounds of ammunition, and an 11-man crew.

The Netherlands acquired all seven of the Canadian Forces' surviving CH-147s and upgraded them to CH-47D standard. Six more new-build CH-47Ds were delivered in 1995 for a total of 13. The Dutch CH-47Ds feature a number of improvements over U.S. Army CH-47Ds, including a long nose for Bendix weather radar, a "glass cockpit", and improved T55-L-714 engines. As of 2011, the Netherlands shall upgrade 11 of these which will be updated to the CH-47F standard at a later date.
