The H-1 upgrade program refers to the United States Marine Corps's program to develop the AH-1Z Viper and UH-1Y Venom to replace its aging fleets of AH-1W SuperCobras and UH-1N Twin Hueys. The former is a twin-engine attack helicopter, while the latter is a medium-sized utility helicopter, also twin-engined. The contract was awarded to Bell Helicopter, the original designer and manufacturer of both helicopters, to design these new airframes as modernized attack and utility helicopters with considerable design commonality to reduce operating costs. In August 1995, the Secretary of the Navy authorized the Marine Corps to upgrade its utility and attack helicopters as a bridge until the Joint Replacement Aircraft was available in 2020. In 1996, the Marine Corps launched the H-1 upgrade program by signing a contract with Bell for upgrading 180 AH-1Ws into AH-1Zs and upgrading 100 UH-1Ns into UH-1Ys. While the original contract called for upgrading existing airframes, it was later modified in 2008 to manufacture completely new aircraft. The program also includes aircraft simulators.
