The Douglas SBD Dauntless is a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD (“Scout Bomber Douglas”) was the United States Navy‘s main carrier-based scout/dive bomber from mid-1940 through mid-1944. The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers. The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942.[1] The type earned its nickname “Slow But Deadly” (from its SBD initials) during this period.

Operational History

U.S. Navy and Marine Corps SBDs saw their first action at Pearl Harbor, when most of the Marine Corps SBDs of Marine Scout Bombing Squadron 232 (VMSB-232) were destroyed on the ground at Ewa Mooring Mast Field. Most U.S. Navy SBDs flew from their aircraft carriers, which did not operate in close cooperation with the rest of the fleet. Most Navy SBDs at Pearl Harbor, like their Marine Corps counterparts, were destroyed on the ground.[6] On 10 December 1941, SBDs from USS Enterprise sank the Japanese submarine I-70.

The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
