The Marine Corps has begun a process that will see the inactivation of all units operating conventional helicopters in Hawaii by the end of next year. At least two relatively young AH-1Z Viper attack helicopters are reportedly in the process of being "decommissioned" as part of the plan. The decision to stop flying AH-1Zs, as well as CH-53E Super Stallions and UH-1Y Venoms, at Marine Corps Air Station Kaneohe Bay is a part of a broader, radical force structure redesign the service unveiled last year that also includes the elimination of its entire fleet of M1 Abrams main battle tanks, among other things.
