Design and development

In 1930, the British Air Ministry issued Specification M.1/30 for a carrier based torpedo bomber to replace the Blackburn Ripon, to be powered by the Rolls-Royce Buzzard or Armstrong Siddeley Leopard engines. Prototypes were ordered from Blackburn, Handley Page and Vickers. The Blackburn design, the B-3, was a single bay biplane, with a fabric covered steel tube fuselage, powered by a Buzzard engine. The prototype was first flown on 8 March 1932 Cite book |author=Mason, Francis K |authorlink =

Following relaxation of some of the specifications requirements, Blackburn constructed a second aircraft (also known as the M.1/30A) as a private venture, with a watertight metal monocoque fuselage replacing the previous steel tube fuselage cite book |title=The British Bomber since 1914 |last=Lewis |first=Peter |edition= Third Edition |date= |year=1980 |publisher=Putnam |location= London |isbn= 0 370 30265 6] , this first flying on 24 February 1933. It performed poorly during testing, still being incapable of meeting the performance requirements of the specification even though they had been relaxed, and being too heavy for the carrier deck lifts. As none of the competitors for the specification could meet its requirements, the specification was cancelled, with no aircraft being ordered.
