AH-1Z helicopter to replace AH-1W on MCAS Futenma

7 Nov 2016 | 1stLt Joseph Butterfield, CAMP FOSTER, OKINAWA, Japan III MEF/MCIPAC Consolidated Public Affairs Office

MARINE CORPS AIR STATION FUTENMA, Okinawa - The AH-1Z helicopter will replace III Marine Expeditionary Force’s AH-1W currently stationed at MCAS Futenma this week.

The AH-1Z “Viper” is the world’s most advanced attack helicopter. The AH-1Z has a 0.00 Class-A Mishap rate per 100,000 flight hours compared to the 1.76 Class-A Mishap rate of the AH-1W that it is replacing. The AH-1Z also features an upgraded landing gear, four-bladed composite rotor system and four-bladed tail rotor.

The aircraft swap is a result of the H-1 replacement program which replaces the UH-1N and AH-1W aircraft with the UH-1Y and the AH-1Z, the next generation of U.S. Marine Corps Utility and Attack aircraft. Marine Aircraft Group 36 currently has UH-1Ys stationed at MCAS Futenma. This swap will not result in an increase of aircraft on MCAS Futenma.

III Marine Expeditionary Force remains committed to the U.S.-Japan alliance by providing the most advanced variants of aircraft in the Marine Corps aviation fleet. The AH-1Z goes further and faster than its predecessor, allowing the Marine Corps to respond quickly in support of our treaty with Japan.

普天間航空基地のAH-1W をAH-1Zヘリコプターと交代
 【海兵隊普天間航空基地】AH-1Zヘリコプターが今週、普天間航空基地に配備されている第三海兵遠征軍の現行機AH-1Wと交代します。

AH-1Zヴァイパーは、世界最先端の攻撃ヘリコプターです。同航空機の10万飛行時間あたりのクラスA事故率は0.00、交代されるAH-1WのクラスA事故率は1.76となります。AH-1Zは、改良された着陸装置、4枚ローター複合材システム、4枚尾部ローターを特色としています。

 航空機の交代は、H-1交代プログラムによるもので、現行機のUH-1NとAH-1Wを米海兵隊の次世代汎用攻撃機UH-1YとAH-1Zに交代します。現在、第36海兵航空群は普天間基地にUH-1Yを配備しております。今回の交代により、普天間航空基地の航空機数が増加することはありません。

第三海兵遠征軍は、最先端の変種航空機を海兵隊航空隊に提供することにより、引き続き日米同盟に専心します。AH-1Zは、従来機に対しより遠くより早く飛行し、日本との条約を支援する海兵隊の迅速な対応を可能にします。
