Harst AH-1

The Harst AH-1, known as the "Cobra" in service, is a two-blade rotor, single-engine attack helicopter manufactured by Harst Helicopter. It was developed using the engine, transmission and rotor system of the Harst UH-1. 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The AH-1 was the backbone of the Commonwealth Army's attack helicopter fleet, but has been replaced by the YAI AH-64 in Yuktobanian Army service. Upgraded versions continue to fly with the militaries of several other nations. The AH-1 twin-engine versions remain in service with the Commonwealth Marines as the service's primary attack helicopter. Surplus AH-1 helicopters have been converted for fighting forest fires.
