Two more jet aircraft have been confirmed for Easter's Warbirds Over Wanaka Airshow.

The Royal Australian Air Force is planning to send two light-attack Hawk 127s across the Tasman.

The aircraft are mainly used by the RAAF as lead-in fighter trainers to prepare crews to fly F/A-18 Hornets.

Airshow event manager Mandy Deans said yesterday the Hawk 127s had not been seen at the airshow before.

''Because of their advanced technical capabilities and huge power we are expecting a pretty spectacular display.

''They should be able to land here at Wanaka Airport and we are delighted the Australians have given the go-head for them to come.''

Hawk 127s are two-seater jets about 12m long capable of over 1200kmh.

They are powered by a single Rolls-Royce turbofan engine and can carry Mk 82 bombs, Sidewinder missiles and a 30mm cannon.

Six other jet aircraft - three Aero L-29s, two De Havilland Vampires and an Aero L-39 - are already scheduled to compete head-to-head in jet racing at the airshow.
