A collision between a U.S. anti-submarine surveillance aircraft and a towing vehicle at a U.S. military base in Okinawa on Sunday has been classified as a severe "Class A" mishap, according to data released by the U.S. Naval Safety Center.

The collision at the U.S. Kadena Air Base caused damage to the nose gear and lower fuselage of the P-8 aircraft, but there were no injuries reported.

A Class A mishap is classified as an accident resulting in loss of life or permanent total disability, destruction of an aircraft or damage worth $2 million or more.

The collision came in the wake of the ditching of an MV-22 Osprey tilt-rotor aircraft off Okinawa.

In the incident involving the Osprey based at U.S. Marine Corps Air Station Futenma in Ginowan, two of the five crew members aboard were injured and the plane was destroyed.
