H-47 Chinook Boeing-Vertol

The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than utility and attack helicopters of the 1960s and even many of today. Its primary roles include troop movement, artillery emplacement and battlefield resupply. There is a wide loading ramp at the rear of the fuselage and three external-cargo hooks.
Chinooks have been sold to 16 nations; the largest users are the U.S. Army and the Royal Air Force. The H-47 is now produced by Boeing Integrated Defense Systems.
