The Marine Corps is considering using a massive drone not unlike its MV-22B Osprey to protect ships.
The Air Force added a pair of special operations squadrons in Japan charged with flying and maintaining CV-22 Ospreys.
Melania Trump made history Wednesday by flying in a V-22 Osprey aircraft and onto the deck of an aircraft carrier.
In the last three months, the Osprey is the third Marine Corps aircraft in the region to lose a part while in flight.
The relief comes six months after three Marines were killed when an Osprey attached to VMM-265 crashed off Australia.
