The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.

The failure of Operation Eagle Claw during the Iran hostage crisis in 1980 underscored the requirement for a new long-range, high-speed, vertical-takeoff aircraft for the United States Department of Defense. In response, the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. A partnership between Bell Helicopter and Boeing Helicopters was awarded a development contract in 1983 for the V-22 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 for military service led to many years of development.

The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007; it supplemented and then replaced their Boeing Vertol 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 transportation and medevac operations over Iraq, Afghanistan, Libya and Kuwait.

The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed." The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership.
