Hawker Harrier GR3
For a long time this was the only operational western VTOL aircraft. It is a small ground-attack aircraft. VTOL operation is achieved by the four swivelling nozzles of the R.R. Pegasus engine. The basic concepts dates back to 1960, but production still continues. The type was adopted by the USMC as the AV-8. Later versions have enlarged wings, wing root extensions, and longer noses for additional electronics.
The operational characteristics of Harrier are unique it can operate out of restricted spaces and can deliver with pin-point accuracy a wide range of stores by day or night. Harrier roles include close air support, reconnaissance, fleet air defence and maritime attack and the aircraft has brought a completely new flexibility to offensive air operations on land and at sea.
