Curtiss SBC Helldiver
The Curtiss SBC ''Helldiver'' was a two-seat scout bomber and dive bomber built by the Curtiss-Wright Corporation. It was the last military biplane procured by the United States Navy. Delivered in 1937, it became obsolete even before World War II and was kept well away from combat with Axis fighters.〔Wheeler 1992, p. 27.〕
==Design and development==
In 1932, the U.S. Navy gave Curtiss a contract to design a parasol two-seat monoplane with retractable undercarriage and powered by a Wright R-1510 Whirlwind, intended to be used as a carrier-based fighter. The resulting aircraft, designated the XF12C-1, flew in 1933. Its chosen role was changed first to a scout, and then to a scout-bomber (being redesignated XS4C-1 and XSBC-1 respectively), but the XSBC-1's parasol wing was unsuitable for dive bombing. A revised design was produced for a biplane, with the prototype, designated the XSBC-2, first flying on 9 December 1935.〔Swanborough and Bowers 1976, p. 146.〕
The SBC-3 the initial production model was powered by a Pratt & Whitney R-1535 Twin Wasp Junior. The SBC-3 began operational service in 1938. A total of 83 SBC-3s were built.
The SBC-4 was powered by a Wright R-1820 Cyclone. The SBC-4 entered service in 1939.
