Osprey usage was temporary grounded in Okinawa after a crash involving a U.S. military Osprey December 2016. Due to safety concerns, the use of the Osprey has been controversial in Japan.
In August, three U.S. Marines were killed when an Osprey crashed during routine exercises in Australia. Five Marines were killed in June 2022 during an Osprey crash in California. There was also a crash in March 2022 in Norway killing four and crashes in Syria and Australia in 2017.
The Marine Corps is the service most associated with the tilt rotor MV-22B Osprey, which takes off and lands like a helicopter but then can transition into a fixed wing aircraft while in flight. It is used for transporting personnel and equipment and is lauded for its speed and flexibility.
The aircraft, however, is associated with several deadly crashes and its safety record has been under regular scrutiny.
