Bell AH-1S Cobra
The AH-1 Cobra traces its history to 1965 when Bell Helicopter began development of the design as a private venture. The Cobra is based on the famous UH-1 Huey transport helicopter, and despite the great differences in their appearance, they have over 80 percent of their parts in common. Production began in 1966 and the Cobra was soon in combat over Vietnam. The Cobra was retired from Army service in September 2001. Modernized versions of the Cobra continue in use in the U.S. Marine Corps as well as with several foreign militaries.
