Variants
HC-1BThe pre-1962 designation for Model 114 development aircraft that would be redesignated CH-47 Chinook[1]
CH-47AThe all-weather, medium-lift CH-47A Chinook was powered initially by Lycoming T55-L-5 engines rated at 2,200 horsepower (1,640 kW), but then replaced by the T55-L-7 rated at 2,650 hp (1,980 kW) engines or T55-L-7C engines rated at 2,850 hp (2,130 kW).[1]
ACH-47AThe ACH-47A was originally known as the Armed/Armored CH-47A (or A/ACH-47A). It was officially designated ACH-47A as a U.S. Army Attack Cargo Helicopter, and unofficially referred to as Guns A Go-Go.[1]
CH-47BThe CH-47B was an interim solution while Boeing worked on a more substantially improved CH-47C. The CH-47B was powered by two Lycoming T55-L-7C 2,850 shp (2,130 kW) engines.[1]
CH-47CThe CH-47C principally featured more powerful engines and transmissions. Three sub-versions were built; the first had Lycoming T55-L-7C engines delivering 2,850 shp (2,130 kW).[1]
CH-47DThe 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.[1]
MH-47DThe MH-47D variant was developed for special forces operations and has inflight refueling capability, a fast rope-rappelling system, and other upgrades. The MH-47D was used by U.S. Army 160th Special Operations Aviation Regiment.[1]
MH-47EThe MH-47E has been used by U.S. Army Special Operations. Beginning with the E-model prototype manufactured in 1991, a total of 26 Special Operations Aircraft were produced.[1]
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.
