Overview
- The Marine Corps received its 359th and final MV-22B on July 28, 2026, closing the service’s Program of Record and ending new MV-22B buys for the Corps.
- The Osprey transformed Marine operations by supplying roughly 75% of rotary-wing assault support and logging about 686,500 flight hours across 114 deployments since 2007.
- The program has a troubled safety record with 65 total mishap fatalities reported by CRS and four fatal crashes since 2022 that killed 20 service members, investigations citing hard clutch engagements and proprotor gearbox failures as causes.
- Modernization work now takes priority and includes improved nacelle wiring, a redesigned input quill assembly to prevent hard clutch events, introduction of triple-melted steel proprotor gearboxes, standardized configurations, and continued flight-hour limits on affected components.
- Bell Boeing will keep building CMV-22s for the Navy into 2028 while the Marines begin defining requirements for a Next Generation Assault Support aircraft, creating long-term sustainment and industrial challenges for keeping the fleet safe and mission-capable through 2055.
