SBD Dauntless Facts

February 27, 2020Mack Dean26923 views

The SBD Dauntless Dive Bomber, also known as the Douglas SBD Dauntless, performed the roles of both scout plane and dive bomber for the United States military during World War 2 from 1940 through 1944. The SBD Dauntless was the primary dive bomber and scout plane for the United States Navy between mid-1940 and mid-1944 and was also flown by the United States Marine Corps from both aircraft carriers and land bases in this timeframe. The Dauntless Dive Bomber is best known for its role in helping sink / cripple the Japanese aircraft carriers at the Battle of Midway that occurred in June of 1942. During its combat service, the Douglas SBD was one of the best dive bombers in the world boasting extremely long range, maneuverability, good handling characteristics, defensive armament, ruggedness, good bomb load capacity, and a great diving capability. The SBD was also used by the U.S. Army Air Corps without an arrestor hook which was known as the A-24 Banshee during the war.

SBD Dauntless Dive Bomber Development

In 1935 the Northrop Corporation began design work on the Northrop BT-1. Just two years later, the company was overtaken by

Douglas and the existing design work continued under the Douglas Aircraft Corporation. The BT-2 was then developed from the BT-1 based on modifications that were ordered in November 1937 and were the baseline for the SBD. The first version of the SBD would enter its service life in the middle of 1939. A year later, the U.S. Navy and USMC would place orders for the new bomber which would be designated as the SBD-1 (USMC) and SBD-2 (USN). The next version of the dive bomber was the SBD-3 which started to be manufactured in early 1941 and would feature four machine guns, self-sealing fuel tanks, as well as increased armor. The succeeding SBD-4 would provide an upgraded electrical system (12 volt compared to 6 volt), and some of these aircraft were converted into pure SBD-4P recon aircraft.

The SBD-5 was the subsequently developed model by the Douglas factory located in Tulsa, Oklahoma. The SBD-5 would be the most produced version of the aircraft during WW2 with more than 2,400 of the model being built. This version would feature increased ammo storage as well as a 1,200 Horse Power engine. The SBD would be flown by the US Navy, USMC, Royal Navy, New Zealand Air Force, Free French Air Forces, and the U.S. Army Air Force (also called the A-24 Banshee).

Operational Employment of the SBD Dauntless in World War 2

SBD Dauntless World War 2 Timeline

December 7, 1941 – 18 SBDs from the Enterprise took part in defense of Pearl Harbor. USMC SBDs that were assigned to VMSB-232 (Marine Scout Bombing Squadron 232) were destroyed on the ground at Ewa Mooring Mast Field.

December 10, 1941 – SBDs based from the USS Enterprise sank Japanese submarine, I-70.

February – March 1942 – SBDs from USS Enterprise, USS Yorktown, and USS Lexington took part in raids on Japanese forces located in: Gilbert Islands, the Marshall Islands, New Guinea, Rabaul, Wake Island, and Marcus Island.

May 4-8, 1942 – First major use of the SBD aircraft in combat at the Battle of the Coral Sea. The SBDs and TBD Devastor aircraft of the U.S. forces sank Japanese light aircraft carrier (CVL) Shōhō and damaged Japanese fleet carrier Shōkaku. The SBDs would also be used to fly anti-torpedo CAP (combat air patrol) and would splash a number of Japanese aircraft attempting to attack the USS Yorktown and USS Lexington.

June 1942 – Battle of Midway. Four squadrons of USN SBD bombers were employed and sank or severely damaged all four Japanese aircraft carriers present at the battle in addition to inflicting significant damage on the Japanese heavy cruisers present at the battle.

August 7, 1942 – Battle of Guadalcanal. SBDs operated off of both the U.S. aircraft carriers and from Henderson Field located on the island. The SBDs would attack Japanese shipping throughout the American campaign and helped sink Japanese carrier Ryūjō, sunk near the Solomon Islands on August 24th, 1942. The SBDs also sank a cruiser and nine transport ships during the campaign.

November 1942. SBDs were employed in the Atlantic Theater during Operation Torch flying from the USS Ranger and two escort carriers.

June 1944 – Battle of the Philippine Sea.  SBDs had started being replaced in the U.S. Navy by the SB2C Helldiver. They did take part in a long range strike against the Japanese fleet during the battle that was at and beyond their combat radius. Only 115 aircraft made it back to the force from the original 215. 80 or more of the lost aircraft were due to running out of fuel. 26 SBDs took part in the raid and all of which made it back to the U.S. aircraft carriers. This would be the last major battle where SBDs would be a significant part of the carrier based air wing. The USMC would continue to use the SBD to the end of World War 2.

July 21st, 1944 – The final SBD would be produced at the Douglas Aircraft factory located in El Segundo, California. From the attack on Pearl Harbor to April of 1944, the SBD would fly approximately 1,189,473 operational hours. The record of the aircraft in battle gives credit to the pilots of the SBD for sinking six Japanese aircraft carriers, 14 cruisers, six destroyers, 15 cargo ships, and large numbers of smaller aircraft.
