The Boeing CH-47 Chinook is a versatile, twin-engine, tandem-rotor heavy-lift transport helicopter of American origin. It was initially designed and launched by Boeing Vertol in the early 1960s, currently Boeing Integrated Defense Systems.

With a top speed of 315 km/h, it is faster than contemporary attack and utility helicopters of the 1960s. It is one of the few aircraft of that time, along with the C-130 Hercules and the UH-1 Iroquois, which is still in production and in front-line service with more than 1,179 manufactured copies. Its main uses include troop transport, artillery use, and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three hooks to hoist external cargo.

The Chinook has been exported to sixteen countries. Although some nations use larger helicopters, such as the Russian Mil Mi-26, the CH-47 remains the heaviest cargo helicopter used by its main operators, the United States Army and Royal Air Force.
