Design and development
In response to a Navy request for proposals issued on 3 February 1941 for a replacement for the SB2C,[1][2] Curtiss designed an improved and enlarged version of the Helldiver, which was, at the time, still only in the process of flight testing. A larger tail, revised wing planform and tricycle landing gear distinguished the aircraft from its predecessor,[1] in addition to the provision of heavier armament.
An internal bomb bay in the midsection of the aircraft could carry up to 4,000 pounds (1,800 kg) of bombs, or alternatively, two torpedoes could be carried in semi-submerged mountings. In addition, hardpoints for two 500-pound (230 kg) bombs were fitted under the wings.[1] Forward-firing armament proposals were for the aircraft to be fitted with either six .50-calibre machine guns or four 20mm cannon in the wings, while defensive armament was planned to be fitted in a power-operated turret.[1]
Power was intended to be provided by a
As the project progressed during 1942, however, it was determined to be inferior to the competing Douglas aircraft.[1] This, combined with the aircraft's requirement for 115/145 octane fuel, which was considered difficult to handle aboard ship,[1] and the decision by the Bureau of Aeronautics that future attack aircraft would be single-seat aircraft,[3] led to the Navy's decision to cancel the prototype contract, and no examples of the XSB3C were ever built.[1]
