The AH-1 Cobra (Bell 209) helicopter is an attack helicopter in the classic layout, which uses many components of its "big brother" UH-1 Huey. The first flight of the AH-1 prototype took place on September 7, 1965, and the helicopter went into mass production in the same year. During the Vietnam War, 1,126 G-model machines were produced, of which 279 were lost in combat. Due to the high reliability of the structure, small side profile and good performance, the helicopter remains in service to this day in the United States Marine Corps. The AH-1 allowed the US Army to fully implement the theoretical assumption of air infantry ("air cavalry") through fire support of landborne infantry units. Today, the AH-1 Cobra is primarily used against an armored celon. Since 1965, several versions of this successful helicopter were created, including: AH-1G (basic version), AH-1J (twin-engine version), AH-1Q (version armed with TOW missiles). Technical data: Maximum speed: 333 km/h; maximum range (depending on version): 507-574 km, armament: fixed-1 20mm M197 three-barreled cannon, lance rockets, guided missiles, unguided missiles and cannon pods.
