As you've started the Gloster F.5/34 three years ahead of OTL can the Hurricane and Spitfire be started 3 years ahead of OTL too? In the case of the latter build a prototype with the Goshawk engine to Specification F.7/30 instead of the Supermarine Type 224. The prototype Hurricane of TTL would probably have to have a Goshawk or Kestrel engine too.Chapter 3: 1931
Meanwhile in Gloster itself, the competition between the two designs of the Gladiator as well as the F.5/34 was well underway. The new Air Ministry F.5/34 Specification however meant that the Gloster Gladiator would certainly fall to some lengths to catch up to the specifications. Therefore at the end of the year, the Gloster F.5/34 renamed to be Gloster Damocles started research and initial prototype production in the United Kingdom and Gloster itself.
The Germans flew the Bf109 prototype with a Kestrel, the Bf109A-C had the Jumo 210, the Bf109D had the DB600 and the Bf109E had the DB601.
Can Specification B.9/32 be four a four-engine heavy bomber? That would make the Hampden and Wellington four-engine aircraft. The prototypes would fly at about the same time as the Boeing B-17, Dornier Do19 and Junkers Ju89.
Can Specification P.27/32 allow two-engine aircraft? AIUI the Fairey Battle was to have had the Griffon, which was begun in the early 1930s and then suspended for about 5 years to allow Rolls Royce to concentrate on the Merlin. A "Twin-Battle" would be faster and have a better power-to-weight ratio. In addition to being a better bomber in the early part of the war it aught to make a better interim night fighter than the Blenheim and Defiant.
