Marine Light Attack Helicopter Squadron 267 AH-1Z Viper and UH-1Y Venom helicopters past Mount Fuji, Shizuoka, Japan, March 12, 2017. The squadron, currently supporting Marine Aircraft Group 36, 1st Marine Aircraft Wing, III Marine Expeditionary Force through the unit deployment program, validated the long-range capability of auxiliary fuel tanks on their H-1 platform helicopters by flying 314 nautical miles during one leg of the four-day mission, March 10. These aircrafts’ extended range is crucial to maintaining a stronger, more capable forward-deployed force in readiness in the Indo-Asia-Pacific region. The squadron is based out of Camp Pendleton, California. (U.S. Marine Corps photo by Lance Cpl. Andy Martinez)

Description

H-1’s provide the MAGTF commander with attack and utility capability performing all 6 functions of Marine aviation. The H-1 program consists of three type/model/series (T/M/S) aircraft: the legacy AH- 1W, the AH-1Z and UH-1Y. The program is a single acquisition program leveraging 85% commonality of major components, enhancing deployability and maintainability. The UH-1Y has fully replaced the UH-1N. The fleet is currently transitioning from the AH-1W to the AH-1Z. The AH-1Z transition is expected to be complete in 2021.

Operational Impact

The AH-1W remains a highly capable attack platform, and remains relevant on the modern battlefield. The AH-1W will continue to serve into 2021 as the force transitions to the AH-1Z.

The AH-1Z Viper is the next generation of attack aircraft currently replacing the AH-1W. Speed, range, and payload have been increased significantly, while decreasing maintenance workloads, training timelines, and total ownership cost. The advanced cockpit, common to the AH-1Z and UH-1Y, reduces operator workload, improves SA, and provides growth potential for future weapons and joint digital interoperability enhancements. The cockpit systems assimilate planning, communications, navigation, digital fire control, day/night targeting, and weapons systems in mirror-imaged crew stations.

The UH-1Y Venom is the next generation of utility aircraft. Speed, range, and payload have been increased, with decreased supportability demands, training timelines, and total ownership cost. The advanced cockpit is common to both AH-1Z and UH-1Y, reduces operator workload, improves SA and provides growth potential for future weapons and interoperability.

Program Status

All HMLAs now operate the UH-1Y. MAG-39: All 4 HMLAs, HMLAT-303 (FRS) has fully transitioned to UH-1Y and AH-1Z. UDP and 31st MEU have fully transitioned to the AH-1Z. MAG-24: 1 HMLA is currently in transition. Completes Jun 2018. MAG-29: 2 HMLAs begin transition 1QFY2019. 4th MAW: 2 HMLAs begin transition 3QFY2020.
