XF12C


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 By the time the XF12C-1 was tested by the US Navy in October 1933, the Twin Whirlwind engine had been replaced by a Wright SR-1820-80 Cyclone single-row radial.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.
Among the evaluations of the Model 73 XF12C-1 was a dive bombing test on 14 June 1934 that resulted in a failure of the parasol monoplane wing assembly. Though the pilot and machine were wholly spared, the prototype was nonetheless heavily damaged. Testing had shown that the parasol wing assembly was generally unfit for the stresses of what the new aircraft would be called upon to achieve. As a result, the US Navy ordered a new prototype to fall in line with stricter requirements. Curtiss once again delivered an answer, this time the Model 77, to which the US Navy affixed the designation of XSBC-2.
