Joint Replacement Aircraft [JRA]
The H-1 Helicopter Upgrade program will provide a bridge to a Joint Replacement Aircraft in the 2020 timeframe.
Under this program, the Marine Corps is making extensive improvements to its aging fleets of UH-1N utility and AH-1W attack helicopters. The program provides for 280 existing airframes (100 UH-1N and 180 AH-1W) to be remanufactured and fitted with a newly developed drivetrain incorporating a four-bladed, all-composite rotor system. Increased commonality between the aircraft will enhance maintainability and deployability. The planned avionics upgrade will also enhance joint interoperability. Together, these upgrades will reduce program life-cycle costs, significantly improve operational capability, and extend the service life of both helicopter fleets.
