SBD Dauntless, Blue/White Airplane Model Toy. Mahogany Wood Model Aircraft Scale: 1/28.The Douglas SBD Dauntless was a naval dive bomber made by Douglas during World War II. The SBD was the United States Navy's main dive bomber from mid-1940 until late 1943, when it was supplanted, although not entirely replaced, by the SB2C Helldiver. The Northrop BT-1 provided the basis for the SBD, which began manufacture in 1940. Ed Heinemann led a team of designers who considered a development with a 1,000 hp (746 kW) Wright Cyclone powerplant. A year earlier, both the U.S. Navy and Marine Corps had placed orders for the new dive bombers, designated the SBD-1 and SBD-2 (the latter had increased fuel capacity and different armament). The SBD-1 went to the Marine Corps in late 1940, and the SBD-2 went to the Navy in early 1941.
