AIRCRAFT BRIEF

The Boeing CH-47 Chinook is a tandem-rotor heavy-lift helicopter that first flew in 1961 and entered U.S. Army service in 1962, and it remains one of the longest-serving and most widely exported military helicopters in the world. Its tandem-rotor layout eliminates the anti-torque tail rotor and provides exceptional lift, allowing it to carry troops, artillery, vehicles, and slung cargo. The CH-47F is the modernized variant, introducing a digital CAAS glass cockpit, a Digital Advanced Flight Control System (DAFCS), a stronger monolithic airframe, and uprated T55-GA-714A engines.
