Which major battle is considered the turning point in the Pacific theater?

The Battle of Midway is widely considered a turning point in the Pacific theater of World War II. Fought from 4 to 7 June 1942, it gave the United States a decisive victory over Japan six months after the attack on Pearl Harbor.

Japan intended to capture Midway Atoll and lure the remaining U.S. aircraft carriers into a trap. American code breakers, however, determined the likely location and timing of the Japanese attack. U.S. commanders positioned carriers in advance, allowing American aircraft to strike Japan’s carrier force when its planes and weapons were being reorganized.

Japan lost four fleet carriers—Akagi, Kaga, Sōryū, and Hiryū—along with many experienced pilots and aircrew. The United States lost the carrier Yorktown, but its surviving carriers and industrial capacity allowed it to recover. The victory halted Japan’s momentum and shifted the strategic initiative to the Allies, although historians also emphasize the Guadalcanal campaign as part of the broader turning point. The Battle of the Coral Sea was important, but it did not produce the same decisive carrier losses.
