Battle of Midway
The heavy cruiser remained in Pearl Harbor only until 30 May. On that day, she returned to sea with the hastily repaired YORKTOWN to prepare to meet yet another major thrust by the Japanese fleet — this one aimed at Midway. Air searches from that island spotted the enemy's Midway Occupation Force — made up of transports, minesweepers, and two seaplane carriers — early on 3 June, but the enemy carrier force eluded detection until early in the morning of the 4th.
ASTORIA screened YORKTOWN as the carrier began launching strike aircraft at about 0840. While the planes droned off to make their contribution to the destruction of the Japanese carrier force, ASTORIA and her colleagues prepared for the inevitable Japanese reply.
The counterstroke, however, did not come until a few minutes before noon as YORKTOWN's victorious aviators began to return to their ship. 18 Aichi D3A1 "Val" dive bombers came in to attack the carrier. F4F-4 Wildcat fighters from Fighting Squadron 3 (VF-3) accounted for 10 of the intruders, but the remaining eight managed to penetrate the combat air patrol (CAP). ASTORIA teamed up with PORTLAND CA-33 and the screening destroyers to splash another two of the attackers. The remaining six, however, succeeded in attacking YORKTOWN, and three of those scored hits. One of the three hit the carrier's stack, causing fires in her uptakes that literally smoked RADM Fletcher and his staff out of flag plot. At about 1310, he shifted his flag to Astoria.
