MV-22B Osprey Program of Record
US Marine Corps tiltrotor aircraft program, jointly built by Bell (Textron) and Boeing; program of record completed July 2026 with delivery of the 359th and final aircraft.
The MV-22B Osprey is a tiltrotor aircraft jointly built by Bell (a Textron company) and Boeing for the US Marine Corps, combining helicopter vertical takeoff/landing with fixed-wing cruise speed and range. The program of record was completed on July 28, 2026 with delivery of the 359th and final aircraft, after roughly 20 years of production. The fleet has flown more than 683,300 hours across 114 deployments since 2007, providing about 75% of Marine Corps rotary-wing assault support. Despite past hard-clutch-engagement safety issues, the Marine Corps intends to keep and modernize the Osprey fleet — improving wiring, working toward pro-rotor gearboxes, standardizing the fleet, and redesigning parts for safety — through 2055.
