The CH-47 Chinook is a tandem-rotor, twin-engine heavy-lift helicopter originally developed by Vertol and now manufactured by Boeing Defense, Space & Security. It is used mainly for troop transport, cargo lift, search and rescue, casualty evacuation, special operations, and disaster relief. The aircraft first flew in 1961 and entered service in 1962.
Design
The CH-47 uses a tandem-rotor layout with two large, counter-rotating rotors. This design provides lift and stability without a tail rotor and allows a rear ramp for loading cargo and vehicles.
Operational role
The Chinook is a multi-mission transport helicopter used for moving troops and cargo, battlefield resupply, medical evacuation, special operations, and humanitarian relief. Its heavy-lift capacity makes it useful on unprepared terrain and in demanding conditions.
Service history
The aircraft first flew in 1961 and entered service in 1962. It was originally developed by Vertol and later associated with Boeing after Boeing’s acquisition of Vertol.
Variants and upgrades
The CH-47 has been produced in multiple versions, including the CH-47F. Boeing continues to market upgraded H-47/CH-47 variants, including Block II modernization efforts.
