The MV-22 Osprey has become the cornerstone of our Corps assault support capability, with the speed, endurance, and survivability needed to fight and win on tomorrows battlefield. This combat multiplier represents a quantum improvement in strategic mobility and tactical flexibility for expeditionary forces. MV-22 Osprey utilizes tiltrotor technology to combine the vertical performance of a helicopter with the speed and range of a fixed-wing aircraft. With its rotors in vertical position, it can take off, land and hover like a helicopter. Once airborne, it can convert to a turboprop airplane capable of high-speed, high-altitude flight. This combination results in global reach capabilities that allow the MV-22 to fill an operational niche unlike any other aircraft. (U.S. Marine Corps video by Lance Cpl. Andy Martinez/Released)
