History

Designed to meet the 1934 U.S. Navy design request for a new dive-bomber design, the Northrop XBT-1 was the progenitor of the "Slow But Deadly" Dauntless, which was the scourge of the Japanese Navy. The XBT-1 was designed for strength, using a multi-cellular wing structure but had horrible handling characteristics, which resulted in several fatal crashes.

Addressing these faults, Northrop took their revised XBT-2 design to the wind-tunnel at Langley and spent six months making the recommended changes. But before it could be completed, Jack Northrop resigned and the company's offices became Douglas Aviation's El Seguendo division. The XBT-2 was thus redesignated the XSBD-1 to reflect both the new company and the Navy's new Scout Bomber classification.

With the acceptance of the type by the Navy in February 1939, an order for 144 SBD-1s was placed and production commenced. The SBD-1 featured a pair of .50 caliber machine guns mounted in the cowl and firing through the propeller arc. The primary offensive armament was a single 1600 lb. bomb mounted on a special "crutch" under the fuselage. During a dive, the crutch could be swung down so that the bomb could clear the propeller.

Hard points under each wing allowed the SBD-1 to carry an additional pair of 100 lb. bombs or depth charges. For defensive purposes, the radio operator had a .30 caliber machine gun on a flex mount positioned to fire aft.

However, the 210-gallon internal fuel capacity was calculated to give an effective range of only 200 miles, once form-up and landing pattern times were added to the equation. Douglas said they could fix the problem and starting with the 58th production plane added 100 gallons of fuel, along with a few other minor changes, the result being designated the SBD-2.

By the time of Pearl Harbor, the Enterprise's VS-6 and VB-6 along with the Lexington's VS-2 and VB-2 squadrons were equipped with the SBD-2. On Wednesday, December 10, 1941, a Dauntless flown by Lt. C.E. Dickson of VS-6 scored the first enemy ship sunk by a Dauntless, the Japanese submarine I-70. During the coming year, the Dauntless would go on to sink more enemy shipping than all other aircraft combined.

The Dauntless was the only plane to participate in all five major carrier-only naval engagements in the Pacific and it broke the back of the Japanese Navy at Midway, sinking three enemy carriers in a space of less than 30 minutes. Although considered obsolescent when it was introduced, the Dauntless served as the principal U.S. Navy ship-based dive-bomber until late 1944 and also served with the Royal Navy.
