The B-2 was aimed mainly at the military trainer market, and the prototype B-2 was shipped to Lisbon in September 1933 for evaluation by Portugal. Although it performed well in the evaluation, the Portuguese preferred a tandem layout, and purchased the de Havilland Tiger Moth. Although not successful in competing for major military orders, the B-2 continued in production to equip civilian flying schools in the United Kingdom that were busy training pilots for the Royal Air Force under the RAF expansion scheme, with the B-2 equipping flying schools owned by Blackburn at Brough Aerodrome and London Air Park, Hanworth. A total of 42 B-2s, including the prototype, were built, with production continuing until 1937.
