The Bell AH-1Z Viper is a twin-engine attack helicopter based on the AH-1W SuperCobra, that was developed for the United States Marine Corps. The AH-1Z features a four-blade, bearingless, composite main rotor system, uprated transmission, and a new target sighting system.[4] The AH-1Z is part of the H-1 upgrade program. It is also called "Zulu Cobra" in reference to its variant letter. The US Marine Corps has finally cleared the Bell Helicopter AH-1Z Viper for operations, only a few weeks ahead of a decision to launch full-rate production. Declared "operationally effective and suitable" on 29 September, the AH-1Z programme can close the book on a protracted, four-year operational evaluation (OPEVAL) process delayed by reliability and technical glitches. "The AH-1Z has come a long way through development and it has finally proven itself as a lethal and reliable attack helicopter," says Col Harry Hewson, programme manager for USMC light and attack helicopters.

The US Naval Air Systems Command says the OPEVAL report found "the AH-1Z fire control and additional weapons delivery modes allowed for improved weapons delivery accuracy, reduced pilot workload and enhanced employment flexibility compared with the AH-1W". The USMC plans to remanufacture and build a total of 189 AH-1Z attack helicopters through 2021. Aspects of the AH-1Z date back to the Bell 249 in 1979, which was basically an AH-1S equipped with the four-blade main rotor system from the Bell 412. This helicopter demonstrated Bell's Cobra II design at the Farnborough Airshow in 1980. The Cobra II was to be equipped with Hellfire missiles, a new targeting system and improved engines. Later came the Cobra 2000 proposal which included General Electric T700 engines and a four-blade rotor. This design drew interest from the US Marine Corps, but funding was not available. In 1993, Bell proposed an AH-1W-based version for the UK's new attack helicopter program. The derivative design, named CobraVenom, featured a modern digital cockpit and could carry TOWs, Hellfire or Brimstone missiles. The CobraVenom design was altered in 1995 by changing to a four-blade rotor system. The design lost to the AH-64D later that year however. AH-1Z Viper (Wallpaper 1).
