Britain, France, Mexico, New Zealand, and the United States used the SBD Dauntless.
The Dauntless entered service in late 1940.
The dive attack usually occurred from 15,000' - 20,000' / 4,500 m - 6,000 m and reached 70°.
The famous saying "Scratch one flat-top" was said by Pilot Lieutenant Robert Dixon in his attack in a SBD Dauntless on the carrier Shoho.
The SBD sank more ships in the Pacific than any other plane.
In 1940 SBD-1s were assigned to the Marine Corps VMB-2 and in 1941 to the VMB-1.
In 1941 SBD-2s were placed on the USS Enterprise in the VB-6 and VS-6 and on the USS Lexington with the VB-2.
In the December 1941 SBD-3s were assigned to the USS Lexington, USS Saratoga, USS Yorktown, and USS Enterprise. A total of 584 SBD-3s were assigned to squadrons by December 1941.
Typically if 18 scouts were launched, pairs would search out 200 miles and then turn 20 - 50 miles when they would then fly to where the carrier was supposed to be.
By the time of Pearl Harbor 584 SBD-3s had been delivered. They equipped the Enterprise, Lexington, Saratoga, and Yorktown.
The Douglas SBD-3 Dauntlesses on the USS Enterprise, USS Hornet, and USS Yorktown was critical in the destruction of the Japanese carriers. In less than two minutes 54 SBDs struck the fatal blows that lead to the destruction of the IJN Akagi, IJN Kaga, and IJN Soryu. The IJN Hiryu was also received damage from the SBD Dauntlesses.
One SBD Dauntless gunner shot down seven Mitsubishi Zero fighters in two days.
United States Army
The SBD was sent to the Philippines in November 1941. When the Japanese took over, they were moved to Australia. In February 1942 they were moved to the Dutch Indies where they didn't perform very well.
Britain's Fleet Air Arm
The FAA were supplied with SBD-5s but weren't used operationally.
A-24Bs and SBD-5s were supplied to France which used them against the Germans along the Atlantic Coast. The Free French received about 40 - 50 A-24Bs in 1943. Training was conducted in Morocco and Algeria.
The Mexicans used A-24Bs on anti-submarine patrols in the Caribbean.
The Royal New Zealand Air Force (RNZAF) used the SBD-2s in the No 25 Squadron from 1943 - 1944. They were commanded by Squadron Leader T. J. MacLean de Lange.
