The Joint Program Office declined to comment to Military.com regarding the restriction. A spokesperson for the Marine Corps could not provide details on the restriction but said efforts are underway to return the aircraft to full operations. Pedro Caballero, a spokesperson for the Marine Corps, told Military.com when asked whether the restrictions applied to its roughly 350 Ospreys, the vast majority of the military's fleet. US Marine Corps MV-22B Ospreys take off at Port Darwin in Australia. An MV-22B Osprey conducts an external lift with US Marines during helicopter support team training at Marine Corps Air Station in Miramar, California.
