Bell AH-1F 'Cobra' attack helicopter. #100.
The Bell AH-1 'Cobra' is a two-blade, single-engine attack helicopter manufactured by Bell Helicopter. It was developed using the engine, transmission and rotor system of the Bell UH-1 Iroquois. A member of the prolific Huey family, the AH-1 is also referred to as the 'HueyCobra' or 'Snake'. The AH-1 was the backbone of the United States Army's attack helicopter fleet, but has been replaced by the AH-64 Apache in Army service. Upgraded versions continue to fly with the militaries of several other nations. The AH-1 twin-engine versions remain in service with United States Marine Corps (USMC) as the service's primary attack helicopter. -[Wikipedia]
