The Curtiss XBTC was an experimental single-seat, single-engine torpedo bomber aircraft developed during World War II.

Design and development

The XBTC-2 "Model A" had a conventional wing.

The Curtiss XBTC-1 (Model 96) was a low-wing monoplane with retractable tailwheel landing gear which used a 2,200 hp (1,641 kW) Wright R-3350 radial engine. It was entered in a 1943 United States Navy competition against the Douglas XBTD-1 Destroyer II, Martin XBTM-1 Mauler, and Kaiser-Fleetwings XBTK-1. The BTC-2 should have used the Pratt & Whitney R-4360 engine, but problems with the Wright engine led to the further development of the BTC-2. Despite its power and "first-class performance and weapon-carrying capacity", it lost to the XBT2D-1 (redesignated as the AD-1 Skyraider) and the BTM-1 (similarly redesignated AM-1) Mauler, which were already building. Two VBTC-2s were built, each having a different wing. The "Model A" had a standard wing and flaps; the "Model B" featured a full span Duplex flap wing with a straight trailing edge and a swept-back leading edge. Both had the 3,000 hp (2,237 kW) Pratt & Whitney XR-4360-8A equipped with contrarotating propellers. The planes were delivered to the Naval Air Test Center at Patuxent River, Maryland (USA), in July 1946. One plane crashed in February 1947 the other in August 1947.

The United States Army Air Force assigned the designation A-40 to a proposed 'de-navalised' version of the XBTC; however, the USAAF decided not to acquire any further single-engine attack aircraft and the project was cancelled.^{[citation needed]}
