[i]The single turbofan engine is the Rolls-Royce Pegasus Mark 104 or Mark 106 which has four rotatable cascade-type exhaust nozzles. For take-off, the nozzles are initially in the fully aft position and then they are rotated partially downwards for lift off and acceleration. [b]Viffing (vectoring in forward flight), a form of advanced combat manoeuvre developed by V/STOL pilots, is achieved by vectoring the nozzles at high speed for sudden deceleration and very tight turns.[/b] [/i]

[i]With a radar and the ability to carry the sidewinder radar, and [b]its unique ability to perform some outrageous manoeuvres in mid-air (Such as Viffing, vectoring the engine exhausts to punch out of a horizontal flight path)[/b] and the superbly trained, well-motivated pilots of the Fleet Air Arm, the Sea Harrier would go on to claim combat victories throughout the Falklands war. Losing none in air-to-air engagements. The aircraft achieved a serviceability of over 90 percent in the Falklands War. 28 Sea Harriers took part in the war, flying from H.M.S. Invincible and H.M.S. Hermes. [/i]
