tiltrotor aircraft with both a vertical takeoff and landing (VTOL),
and short takeoff and landing (STOL) capability.
It is designed to combine the functionality of a conventional
helicopter with the long-range, high-speed cruise performance of
a turboprop aircraft.
The V-22 originated from the United States Department of Defense
Joint-service Vertical take-off/landing Experimental (JVX) aircraft
program started in 1981.
The team of Bell Helicopter and Boeing Helicopters was awarded a
development contract in 1983 for the tiltrotor aircraft.
The Bell Boeing team jointly produce the aircraft.
The V-22 first flew in 1989, and began flight testing and design alterations; the complexity and difficulties of being the first tiltrotor intended for military service in the world led to many years of development.
The United States Marine Corps began crew training for the Ospreyin 2000, and fielded it in 2007; it is supplementing and will
eventually replace their CH-46 Sea Knights. The Osprey's other operator,
the U.S. Air Force, fielded their version of the tiltrotor in 2009.
Since entering service with the U.S. Marine Corps and Air Force,
the Osprey has been deployed in both combat and rescue operations
over Iraq, Afghanistan and Libya.
