US Marine Corps four ship AV-8B Harrier II at NAS San Diego.
The AV-8B Harrier II is a subsonic attack aircraft. It retains the basic layout of the Hawker Siddeley Harrier, with horizontal stabilizers and shoulder-mounted wings featuring prominent anhedral. The aircraft is powered by a single Rolls-Royce Pegasus turbofan engine; the Pegasus's two intakes and four synchronized vectorable nozzles are located close to the turbine; two nozzles are near the forward, cold end of the engine and two nozzles are near the rear, hot end of the engine. This arrangement contrasts with most fixed-wing aircraft, which have their engine nozzles at the rear. The Harrier II also has smaller valve-controlled nozzles in the nose, tail and wingtips to provide control at low airspeeds
