CH-47 Chinook (NO.7)
The Boeing-Vertol CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lifthelicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than contemporary utility and attack helicopters of the 1960s. It is one of the few aircraft of that era such as the C-130 and the UH-1 ‘Huey’ that is still in production and front line service with over 1,179 built so far. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks.
The Chinook was designed and initially produced by Boeing Vertol in the early 1960s. The helicopter is now produced by Boeing Integrated Defense Systems. Chinooks have been sold to 16 nations. Although some nations operate larger helicopters such as the Russian Mil Mi-26, the Chinook remains the heaviest lifting helicopter used by its largest operators, the U.S. Army and the Royal Air Force, see Boeing Chinook (UK variants).
