The Harrier/AV-8 aircraft, with its Rolls-Royce Pegasus engine, was developed primarily for vertical or short takeoff and landing operations. To achieve this it employs nozzles capable of vectoring through more than 90 deg to provide lift and a reaction control system to provide aircraft control in low or zero forward speed operation. These features of the aircraft have also been employed to advantage during combat by vectoring in forward flight (VIFFING). Operational analysis studies have identified the potential combat advantage of post-stall maneuvering (PMS) to improve rate of turn and vehicle/weapon pointing. To achieve any or all of these capabilities will require some degree of propulsion system thrust vectoring. Some particular requirements that the need for thrust vectoring place on the engine design and the technologies involved are addressed.
