“You Call, We Haul”
The highly recognizable twin-engine, tandem rotor heavy-lift Ch-47 Chinook entered service in the early 1960s. With a top speed of 170 knots, it was faster than many contemporary utility and attack helicopters of that era. The Chinook is one of a very few aircraft from that period, such as the C-130 Hercules and the UH-1 Iroquois, that is still in production and front line service.
Improved and more powerful versions of the CH-47 have been developed since the helicopter entered service. The U.S. Army's first major design leap was the now-common CH-47D, which entered service in 1982. Improvements from the CH-47C included upgraded engines, composite rotor blades, a redesigned cockpit to reduce pilot workload, improved and redundant electrical systems, an advanced flight control system and improved avionics.
