The V-22 is a tiltrotor aircraft designed to take off and land vertically like a helicopter and to fly like an airplane by tilting its wing-mounted rotors to function as propellers. The V-22 is being developed toperform various combat missions, including medium lift assault for the Marine Corps, combat search and rescue for the Navy, and long-range special operations for the Air Force. The V-22 is intended to replace the CH-46 Sea Knight helicopter for the Marine Corps and to supplement existing aircraft for the Air Force. The Navy is developing the aircraft under a fixed-price incentive contract with Bell Helicopter Textron, Inc., and Boeing Helicopter Company. The full-scale development contract was awarded in May 1986 and requires the two contractors to produce six aircraft for flight testing and three for ground testing. It included an option to buy 12 aircraft under pilot production. The engine is being developed under a firm fixed-price contract by the Allison Gas Turbine Division of General Motors. (sdw)
