Supermarine B.12/36 bomber


Following issue of Specification B.12/36 Mitchell submitted his tender in September 1936 for a four engined bomber. The plane was a single-spar, mid-wing monoplane, with swept back leading and straight trailing edges. Bombs could be carried in the fuselage as well as in the wings, reducing the overall size of the planes fuselage. Three possible engines were proposed (see below). The plans were accepted by the Air Ministry but unfortuanely the two prototypes, along with the detailed plans, were destroyed by the bombing of the Supermarine Works, Woolston in September 1940.

Type: Six crew bomber
Engines: Four either 1,100hp Rolls-Royce Merlin, or 1,330hp Bristol Hercules, or 1,100 Napier Dagger
Max speed: Either 345mph at 14,500ft, or 360mph at 18,000ft, or 325mph at 17,000ft respectively
Service ceiling: Either 30,000ft, or 33,000ft, or 30,000ft respectively
Range: 3,000 miles
Armament: Front, rear and retractable mid turret.
Bomb-carrying capacity: 21,000lbs

NB As these types never flew the above specifications are estimates.

And spec 12/36 gave birth to

Manchester / Lancaster
Oh, yerh, it's unlucky, if the plan not was burned, Britian might has heavy bomber eralier. Thanks for your post
It was done on many occassions including with the Stirling or Halifax, can never remember which...........

and the Manchester/Lancaster and the H.P.56/Halifax come from specification B.13/36, not B.12/36.............
The idea of having the bombs within the wing structure would've been a dead end. It was thought that many small bombs would be the ideal load. What was needed was a cavernous bomb bay - to house big bombs. The Lancaster Halifax were able to load the 4,000lb bomb and indeed the 'tallboy' 'grand slam' penetration bombs, because the initial specification called for the option of carrying a torpedo!
Such was the need for 4,000 lb bomb carriers that the Mosquito was adapted to carry one.
plus of course fuel could no longer be carried in the wings so i can only assume it went in the fusilage? massive CoG problems as fuel is used during flight!
