Between 7:00am to 10:26am, Akagi was targeted during three different attacks by American U. S. Navy (USN) carrier aircraft and U. S. Army Air Force (USAAF) land based aircraft but was undamaged by the first two attacks. During the third attack, sustains two bomb hits and a near miss.
At 7:10am, Akagi spots six TBF Avengers approaching low then four B-26 Marauders from Midway Airfield that attempted a torpedo attack. Intercepting, the Akagi Combat Air Patrol (CAP) of A6M2 Zeros and defensive anti-aircraft fire shot down two bombers: B-26 "Satan's Playmate" 40-1424 (MIA) and B-26B 41-17570 (MIA).

Muri flew down the flight deck while his gunners strafe and manages to land safely but his damaged bomber sustained 500 bullet holes and was written off.

At 10:26am, Akagi is attacked by three SBD-3 Dauntless led by Lt. Cdr Richard H. Best from VB-6 from USS Enterprise CV-6. Attempting to evade the attacks, Akagi was engaged in a evasive maneuver of a 20° turn to port.
The dive bombers scored a direct hit amidships near the island and causes a fire in both hanger deck levels. This hit mortally damaged the carrier. A second bomb hit passes through the net-guards of the fantail and explodes under the port quarter. A third bomb is a near-miss port-side amidships-forward.
Although the single bomb hit normally would not have been fatal, the carrier was in the preparing to mount another strike and caused aircraft, fuel and armaments to begin exploding and started a fire fueled by aviation fuel. Also, her rudder jammed at 20° port turn resulting in a counter-clockwise circle with her engines starting and spotting erratically. During the attack, a total of 263 crew were lost.
At 11:46, Vice Admiral Chuichi Nagumo transfers his flag to destroyer Nowaki then to light cruiser Nagara. By 4:00pm, all non-essential crew were evacuated while Captain Aoki and a damage control party remain aboard. During the evening and overnight, Akagi continues to burn but remains afloat. After midnight, Admiral Isoroku Yamamoto orders the damaged carrier to be scuttled.
Afterwards, more than 1,070 of the crew were rescued by the four destroyers, including Captain Aoki Taijiro although he had been ordered off the ship he opted to stay aboard. Afterwards, the surviving crew were transfered aboard Mutsu.
On June 5, 1942 at 5:20am Japanese destroyers Arashio, Hagikaze, Maikaze and Nowaki fired four torpedoes that scored two or three hits causing the damaged carrier to sink stern first at roughly Lat 30-30N, Long 178-40W. On September 25, 1942 officially removed from the Navy list.
During October 2019, RV Petrel conducted weeks of grid searches for the shipwreck of Akagi that included 500 square nautical miles within the Papahanaumokuakea Marine National Monument and the use of an Autonomous Underwater Vehicle (AUV). Aboard was Robert Kraft, director of undersea operations and Frank Thompson, a historian with the Naval History and Heritage Command (NHC). On October 19, 2019 the discovery of Kaga was reported as identified by high frequency sonar.
The shipwreck is at a depth of 18,011' / 5,490m upright and largely intact atop the bottom that shows signs of disturbance from when it impacted the sea floor. Some of the flight deck is missing.
