Douglas A-1 Skyraider

Douglas A-1 Skyraider



During World War II the Navy began looking for a new dive-bomber torpedo aircraft to meet its changing tactical and operational requirements. Several planes, among them the AD's direct predecessor, the SB2D/BTD, were developed by the Bureau of Aeronautics. Design difficulties and over-weight problems, however, ultimately led to a decision not to produce the SB2D/BTD. This in turn led to a new design which incorporated the good features of the SB2D/BTD while overcoming its inherent difficulties. The AD series (later redesignated A-1) that emerged from the combined efforts of the Bureau of Aeronautics and Douglas, who was the contractor, had two particularly significant design aspects. First, great emphasis was placed on the importance of the stringent weight control policy. Secondly, the standard bulky, heavy bomb displacing gear was replaced by a light, explosive device which literally blew the bomb clear. In comparison with the most advanced operational dive-bombers in 1945, the AD's initial design compared most favorably with a 27 percent greater top speed and a capability of carrying up to 4,000 pounds of either bombs or torpedoes. For the next 12 years there was constant improvement in the airplane up through the AD-7, and 3,180 Skyraiders were delivered to the Navy, many of which were used during the Korean Conflict and Vietnam War also.

Douglas SB2D

Intended as a successor to the SBD Dauntless, the XSB2D-1 was an unspectacular aircraft. It was large, complicated and heavy, with a R-3350 radial engine, an inverted gull, laminar flow wing, two remote controlled gun turrets, and nosewheel landing gear. Two were built. The USN changed its policy, and the SB2D design was modified to become the single-seat BTD.

Douglas SBD Dauntless


Nicknamed "Barge" or "Clunk" the SBD also went by the nickname "Slow but Deadly." The SBD was the U.S. Navy's principal dive bomber until 1944. It was underpowered, obsolete, and slow but it might be one of the most influential planes in history.
Carrier-based dive bomber, a development of the Northrop BT. The SBD was a small aircraft, slow and vulnerable, and already considered obsolete when it entered service (army version named A-24 Banshee). Nevertheless it sparheaded the early offensives in the Pacific and served throughout WWII. If anything, it was an accurate dive-bomber and got ample opportunity to show it. Its largest success was the destruction of four Japanese carriers in the Battle of Midway.
