Bell 209 HueyCobra
The Bell AH-1 Cobra was the world's first purpose-built attack helicopter, developed quickly during the Vietnam War by fitting a narrow, tandem-cockpit attack fuselage to the proven engine and rotor system of the Bell UH-1 Huey. Its narrow profile, far slimmer than the transport helicopters it evolved from, presented a much smaller target to ground fire while still carrying rockets, missiles, and a chin-mounted gun. That basic tandem-cockpit, narrow-fuselage layout it pioneered became the standard template nearly every attack helicopter built since, including the AH-64 Apache, has followed. Twin-engine SuperCobra variants remained in US Marine Corps service for decades after the original single-engine Cobra's Vietnam debut.
