1/72 日军CH -47JA奇努克双旋翼重型直升机 日本地面自卫队第1直升机编队第103中队, #JG-2981

The CH-47 "Chinook" is a multi-role, twin-engine, tandem-rotor medium-lift transport helicopter developed and manufactured by Boeing. Its unique tandem rotor configuration eliminates the need for a conventional tail rotor, enabling vertical takeoff/landing capabilities while achieving speeds up to 165 mph (265 km/h). Originally designed for troop transport and battlefield resupply missions, the CH-47 has been exported to 16 nations, with the U.S. Army and British Royal Air Force being its largest operators.
 

The CH-47 Chinook helicopter first appeared on the battlefield in Vietnam in 1962. Having served in the U.S. military for over half a century, this aircraft has not only avoided obsolescence but remains highly sought-after by nations worldwide. What explains its enduring appeal?

The CH-47 Chinook traces its origins to development work beginning in 1956. The initial CH-47A variant entered service with the U.S. Army in 1963, subsequently evolving through B, C, and D models. Technical specifications of the CH-47A included:

• Original powerplant: 2 × Lycoming T55-L-5 turboshaft engines
