P.1081 was supposed to have the Tay, but it was behind schedule, so Nene was used with
a Supermarine Attacker-type jet pipe. The January 1950 P.1081 proposal was the result of
an Australian enquiry about an operational P.1052. The first P.1081 was a modification of the
second P.1052,
VX279. First flight was 19 June 1950, stop work order issued 14
November 1950, aircraft lost 3 April 1951, fatal crash. A dedicated new-build prototype
with reheat had been considered but rejected.
The biggest problem with speeding up the Sea Hawk and derivatives is that of production
space, and engineering hours, for the Sea Hawk (which is why development and production
was taken over by Armstrong Whitworth) and that the swept wing 'research aircraft' were
just that, research aircraft. A huge amount of work would have been required to turn them
into 'production, combat ready' aircraft. The 800 lb. gorilla at Hawker was the Hunter project,
so everything else took second place.
So can you fudge the Sea Hawk schedule and get them in just under the wire? Probably,
as they entered service with the RN in March 1953 and the war "ended" in July 1953.
The swept-wing Sea Hawk derivatives? Not likely without an outside entity able to take over
development and production.
I wonder where one could create such an entity?
