The AH-1 Cobra is an attack helicopter manufactured by Bell. It shares a common engine, transmission and rotor system with the older UH-1 "Huey". It is also sometimes referred to as the "HueyCobra" or "Snake".
The AH-1 was once the backbone of the United States Army's attack helicopter fleet, but has been replaced by the AH-64 Apache in Army service.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 United States Army National Guard and several other users.
