摘要

On June 4,1942, the Navy's SBD Dauntless dive bombers changed the course of World War II. These Douglas aircraft, at the Battle of Midway, sank three Japanese carriers in just six minutes. After sending to the bottom Akagi, Kaga, and Soryu, the Navy aircraft a few hours later finished off a fourth, Hiryu. Though the SBD made its greatest mark at Midway, it served brilliantly, especially at the Battle of the Coral Sea and in the Solomons.rnThe SBD design can be traced to the Northrop XBT-2. Douglas acquired Northrop in 1937, giving its name to the new aircraft. The first production model became the SBD-1 (Scout Bomber Douglas-1). The National Advisory Committee for Aeronautics, afederal agency, worked closely with both Northrop and Douglas on cleaning up therndesign. One result: the much debated perforated "Swiss cheese" dive flaps, which permitted the Dauntless to dive steeply without gaining excessive speed. The well-designed SBD served as the Navy's front-line dive bomber until late 1943, when it was superseded by the SB2C Helldiver.
