The Blackburn B-2 was a biplane side-by-side trainer aircraft designed and produced by the British aviation manufacturer Blackburn Aircraft. It was designed as a successor to the Bluebird IV and was derived from it, thus the two aircraft shared much of their design. One major difference of the B-2 was its semi-monocoque all-metal fuselage, which was similar to that of the Blackburn Segrave touring aircraft. On 10 December 1931, the prototype B-2 performed its maiden flight at Brough. It had excellent manoeuvrability and responsive flying controls, and was a relatively forgiving aircraft in flight. During early 1932, the first production aircraft made its first flight, and was participating in competitive air races as early as June of that year.
