Based on a US Navy Bureau of Aeronautics design for a two-seat fighter, the XF12C-1 all-metal parasol monoplane, ordered on 30 June 1932, featured aft-folding wings with leading-edge slats and trailing-edge flaps, and manually-operated retractable main undercarriage members. Flown in July 1933, the XF12C-1 was initially powered by a Wright R-1510-92 two-row radial rated at 625hp at 1830m. By the time the XF12C-1 was tested by the US Navy in October 1933, the Twin Whirlwind engine had been replaced by a Wright SR-1820-80 Cyclone single-row radial. With the discarding of the two-seat fighter category it was redesignated XS4C-1 in December 1933 and the XSBC-1 in January 1934 as a scout-bomber. It crashed during a preliminary demonstration on 14 June 1934, subsequently being replaced by the XSBC-2 biplane.
