The AH-1Z Viper is one of the most powerful, advanced and capable helicopters flying today

The Bell AH-1Z Viper is a modern version of the AH-1 Cobra, the first ever attack helicopter. The modern version is also called Zulu Cobra in reference to its variant letter. Since its introduction in the mid 1960s the original Cobra has been constantly improved and upgraded.

 

The latest AH-1Z Viper is a result of H-1 helicopter upgrade program for the US Marine Corps, that was launched by the US Government in 1996. The Bell helicopter company was eventually awarded a contract to deliver both upgraded and newly-built AH-1Z Vipers to the US Marine Corps. The Viper gunship was developed alongside the UH-1Y Venom utility helicopter under the same program.

The AH-1Z Viper is a direct derivative of the AH-1W Super Cobra. It is one of the most powerful, capable and advanced helicopters, flying today. The AH-1Z made its first flight back in 2000. It was introduced to the US Marine Corps in 2010. Full scale production commenced in 2012. Marines plan to receive a total of 189 Vipers until 2019. These include 131 AH-1W upgraded into AH-1Z and 58 newly built AH-1Z helicopters. In 2015 it was announced that 12 of these gunships will be delivered to Pakistan.

 

 

 

 

Upgrades of the AH-1Z included implementation of state-of-the-art ωɛλρσɳs and digital technology to respond to modern demands for contemporary ωλɾʄλɾɛ. The Viper features outstanding flying and combat capabilities. The AH-1Z has essential changes in propulsion. It is powered by two General Electric T700-GE-401C turboshaft engines and has uprated transmission. One of the main external differenced from the AH-1W is a composite 4-bladed main rotor, instead of the previous 2-bladed rotor. It reduced vibrations by up to 70 percent. It is worth noting that a 2-bladed rotor was a distinctive feature of all previous Bell helicopter models. However due to these changes flying characteristics improved a lot.

Despite all improvements and upgrades appearance of the AH-1Z remains the same. Pilot is seated at the rear and co-pilot/gunner at the front. Layout of two integrated digital cockpits is identical and all systems are duplicated. This helicopter uses off-the-shelf electronic systems. It can operate in day, night, or adverse weather conditions. It has night vision twinned with infrared and new target search and acquisition software. It permits Viper to find and engage targets at long range. It can be fitted with Longbow fire control radar, mounted on wingtip station. Also there is automatic flight control station.
