The Hawker P.1081, also known as the "Australian Fighter" was a prototype British jet aircraft from the mid-twentieth century. The single example built was destroyed in a crash in 1951.
Design and development
In 1949, the
Hawker Aircraft also submitted a proposal, for a swept-wing, swept-tail fighter based on the Hawker P.1052, but using a Rolls-Royce Tay engine. Work began to modify the second prototype of the P.1052 (VX279) along these lines, although the Rolls-Royce Nene engine already fitted was initially retained.[citation needed] To allow an afterburner, the bifurcated tail-pipes of the P.1052 was replaced by a single tail-exit pipe. [2]
VX279, which was now the prototype P.1081, took to the air on 19 June 1950. CAC, evidently planning to build any design accepted by the Australian government, assigned the serial number CA-24 to the P.1081.
By mid-1950, however, the RAAF urgently required a replacement for its Mustangs, some of which were in action in
In November 1950, evidently anticipating that orders for the P.1081 would not eventuate, Hawker decided to cease development. The prototype, which had remained in the UK, was handed over by Hawker to the Royal Aircraft Establishment (RAE). Its swept tail increased the Mach number above that of the P.1052 into the Mach 0.9-0.95 region, providing valuable data that contributed to the design of the axially-powered Hawker Hunter.
On 3 April 1951, the P.1081 prototype was lost with its pilot, Squadron Leader T. S. "Wimpy" Wade.[4]
