The Douglas SBD Dauntless, the Six Minutes Over Midway, and the Dive That Turned the Pacific War

On June 4, 1942, a group of Douglas SBD Dauntless dive bombers - already slated for replacement - executed what may be the most consequential six-minute attack in naval history. Three of Japan’s four fleet carriers at Midway were struck in rapid succession, ending Japan’s offensive dominance in the Pacific. The airplane Washington had written off turned the war.

What Made the Douglas SBD Dauntless a Dive Bomber

Douglas Aircraft began designing the Dauntless in the mid-1930s. The production aircraft flew behind a Wright Cyclone radial producing approximately 1,000 horsepower and cruised at around 185 miles per hour - slow enough that its crews called it the Slow But Deadly. It carried a 1,000-pound bomb on a swing crutch beneath the fuselage, positioned to pull the weapon clear of the propeller arc before release. Two 100-pound bombs hung under the wings. The rear gunner had twin .30-caliber machine guns on a flexible mount; the pilot had twin .50-calibers fixed forward.

The airplane’s defining feature was its perforated split flaps on the trailing edge of the wing. Deployed in a dive, they created drag without disturbing airflow over the control surfaces. A pilot could hold a 70-degree dive angle and maintain full control - critical when the target is maneuvering, antiaircraft fire is closing in, and the altimeter is unwinding fast. Without those flaps, airspeed would climb toward redline before the aim could be settled.

Despite this capability, the Navy had already selected the Curtiss SB2C Helldiver as the Dauntless’s replacement. The Helldiver was faster and larger on paper. It was also plagued by development problems that would keep it out of the Pacific for another year and a half. The Dauntless went to Midway instead.

How the United States Knew Japan Was Coming

The American position at Midway was not luck - it was intelligence.

Commander Joseph Rochefort and his codebreaking team at Station Hypo in Pearl Harbor had broken enough of the Japanese naval code to identify a major operation targeting a location designated “AF.” Rochefort believed AF was Midway Atoll. To confirm it, he arranged for the Midway garrison to transmit a plain-language message reporting that their water distillation plant had failed. Days later, intercepted Japanese traffic noted that AF was running low on fresh water. Confirmed.

Admiral Chester Nimitz used that intelligence to set an ambush. He deployed three carriers northeast of Midway: the Enterprise, the Hornet, and the Yorktown. The Yorktown had taken a bomb hit at the Battle of the Coral Sea weeks earlier and was estimated to need 90 days of repairs. The Pearl Harbor shipyard made her combat-ready in 72 hours.

The Japanese force, under Vice Admiral Chuichi Nagumo, included four fleet carriers - the Akagi, Kaga, Soryu, and Hiryu - plus battleships, cruisers, destroyers, and troop transports. They expected a surprised or absent American fleet. They found neither.

What Went Wrong Before the Dauntlesses Arrived

The early hours of June 4 were a disaster for the Americans.

Japanese aircraft struck Midway at dawn. Brewster Buffalos and a handful of Wildcats scrambled to intercept and were badly outclassed by the Mitsubishi Zero. Midway-based strike aircraft went out to hit the Japanese fleet and were mauled in return. Army Air Force high-altitude bombers dropped from altitude and hit nothing.

Then the torpedo bombers arrived. Torpedo Eight from the Hornet, Torpedo Six from the Enterprise, Torpedo Three from the Yorktown - all flying slow Douglas TBD Devastators at wave-top height, with no fighter escort, into a wall of antiaircraft fire and a swarm of Zeros.

Torpedo Eight had 15 aircraft. All 15 were shot down. The sole survivor was Ensign George Gay, who spent hours in the water watching the battle around him, hiding under a seat cushion to avoid being strafed. Torpedo Six lost 10 of 14 aircraft. Torpedo Three lost 10 of 12.

But those torpedo attacks accomplished something by dying. The Zeros that destroyed the Devastators had come down to sea level to do it. The combat air patrol that should have been covering the carriers at altitude was now at the wave tops, out of position.

High above - at around 15,000 feet - the Dauntlesses were arriving.

How Wade McClusky Found the Fleet

Commander Wade McClusky had been airborne for nearly three and a half hours leading the Enterprise’s dive bomber group. He reached the coordinates where the Japanese fleet was supposed to be and found empty ocean. His aircraft were burning fuel. The math on getting everyone home was getting tight.

McClusky kept looking. Turning southwest, he spotted a white wake far below on the Pacific. It belonged to the Japanese destroyer Arashi, running at full speed after depth-charging the American submarine Nautilus and racing to rejoin the fleet.

McClusky followed the wake.

Four minutes later, four Japanese carriers were spread out below him - flight decks crowded with aircraft, ordnance stacked on hangar decks rather than properly restowed in the magazines, fuel lines run. Everything prepared for the next strike. A perfect target.

At 10:22 AM, McClusky split his force and pushed over. Two squadrons would hit the Kaga and the Akagi.

The Six Minutes That Sank Three Carriers

Lieutenant Commander Dick Best led Bombing Squadron Six into his dive expecting his squadron to follow. Most of them did not. In the noise and chaos of the attack, the majority of Bombing Six broke toward the Kaga with the air group’s main force. Best looked around, found two wingmen, and held his dive toward the Akagi - Admiral Nagumo’s flagship, the carrier that had launched the strike on Pearl Harbor.

Three aircraft against a fleet carrier.

Best’s first bomb struck the Akagi’s flight deck amidships, directly where a strike force was being readied for launch. The blast reached the ordnance on the hangar deck - torpedoes and bombs that had been moved up during the rearming cycle and never returned to the magazines because there was no time. In seconds, the Akagi was a burning wreck. Meanwhile, Bombing Six and Scouting Six put four bombs into the Kaga. The Kaga burned.

Two minutes later, Lieutenant Commander Maxwell Leslie arrived over the Soryu with the Yorktown’s dive bombers. Leslie himself had accidentally armed and released his own bomb during the flight out - a malfunction in the new electrical release system. He dove on the Soryu carrying nothing, released on an empty rack, and pulled out. His squadron put three bombs into the Soryu. The Soryu burned.

In six minutes, three of Japan’s four fleet carriers were fatally struck.

The Hiryu, the Yorktown, and the Afternoon Strike

The fourth carrier, Hiryu, survived the initial attack and launched a counterstrike that hit the Yorktown twice. The Yorktown’s crew fought fires, restored speed, was struck again by a submarine, and was eventually lost. But before she went down, Enterprise Dauntlesses found the Hiryu that afternoon and delivered four bomb hits. The Hiryu sank the following morning.

All four carriers were gone.

What Japan Actually Lost at Midway

The material losses were severe. The strategic losses were irreplaceable.

What Nagumo lost at Midway was not just ships. He lost the air groups - the experienced aircrew, the trained maintainers, the men who had flown together from China to Ceylon. The Imperial Japanese Navy could build new carriers. They could not replace those aviators - not in months, not in years.

Before Midway, Japan was advancing. After Midway, they were holding, then retreating. The strategic initiative in the Pacific passed to the United States on the morning of June 4, 1942, delivered by an airplane most of Washington had already dismissed.

The Dauntless’s Full Record in the Pacific

The SBD Dauntless sank more enemy shipping in the Pacific than any other Allied aircraft of the war. That number deserves to be stated plainly. The Dauntless often gets bracketed between the legendary fighters and heavy bombers in histories of the conflict - the numbers tell a different story.

It flew at the Coral Sea, Midway, the Solomons campaign, and the Philippine Sea. Every time, with crews who were already being told their aircraft was obsolete.

For the complete account, Gordon Prange’s Miracle at Midway and Walter Lord’s Incredible Victory remain the definitive sources. The National Naval Aviation Museum in Pensacola holds a Dauntless on display.

Key Takeaways

The Douglas SBD Dauntless - already slated for replacement - sank three Japanese fleet carriers in approximately six minutes on June 4, 1942, and fatally damaged a fourth the same afternoon.
American codebreakers at Station Hypo confirmed the Japanese target was Midway by planting a false radio message about a broken water distillation plant, then intercepting Japanese confirmation.
The torpedo bomber assault - which cost 35 of 41 attacking aircraft - drew the defending Zeros down to sea level, leaving the carriers unprotected at altitude just as the Dauntlesses arrived.
Commander Wade McClusky found the Japanese fleet by following the wake of the destroyer Arashi, which was steaming to rejoin the fleet after a submarine engagement.
Japan’s irreplaceable loss at Midway was its experienced aircrews, not its warships - a loss that permanently ended Japanese offensive capacity in the Pacific.
