 Because of the pressures of developing and producing the Brewster F2A Buffalo fighter, Brewster was unable to manufacture any production models of the XSBA-1, and the Navy acquired a license to produce the aircraft itself at the Naval Aircraft Factory.In September 1938, the Navy placed an order for 30 production aircraft.Due to pressures of work at the NAF, it did not deliver the first aircraft, now designated the SBN, until November 1940; the remaining aircraft were delivered between June 1941 and March 1942.
