Tough call....
Hawkers P.1051 naval medium bomber. Twin AJ.65.
Potential for a fighter all weather version.... '46
Hawkers P.1057 FAW to F.44/46 OR.227.
Viewed as the best design from a radio and radar perspective. It came down to a choice between this and DH110. DH won on turning circle/ wing loading.
Though had there been more pressing need the Hawker design was expected to complete six months earlier.
They wanted to keep both designs going with three prototypes each. Comittee cancelled Hawkers contract in '47.
June 1949 Gloster P.293 large supersonic fighter bomber.
Needed engines of 12000lb dry with reheat 50% increase. Estimated speed mach 1.2
Essentially a big Delta wing and tail with the fusilage disappearing into the wing. Much like a big and sexy version of the later Javelin.
A smaller fighter version P.291 drawn March '49 had 8 cannon 4 in each wing.

Hawker P.1077 CAP fighter
AWA.165 in Nov '52. Twin Sapphire swept back wing.
EE P.10E 1954-56 ramjet wing powered shortened version of P.10.
Twin RB.123 (10,000lb dry, 16,000lb reheated) for take off and acceleration to ramjet light up speed.
With 36"scanner, and weapon bay for two 10ft long AAMs.
Mach 3 speed, ceiling well over cruising altitude of 70,000ft. Enormous capacity to sustain supersonic flight. As cruising flight used only 25%

f available thrust.
P.10 was the most radical new design of the times but was of serious interest to the Ministry.and was Avro's only serious contender to OR.330 R.156T issued 23 July 1954.
