The Battle of the Philippine Sea was a decisive naval battle of World War II, and the largest aircraft carrier battle in history. It was fought between the navies of the United States and the Empire of Japan. Part of the wider Pacific War, this action occurred on June 19–20, 1944 off the Mariana Islands and also involved Japanese land-based aircraft. The engagement proved disastrous for the Imperial Japanese Navy, which lost three aircraft carriers and some 600 aircraft, termed by Americans the Great Marianas Turkey Shoot. These losses are largely attributed to the obsolescence of the Japanese aircraft and the inexperience of the Japanese carrier aircrew (many experienced pilots had died during the Guadalcanal campaign, Midway and other engagements) in contrast to the U.S. Navy's more modern Grumman F6F Hellcat fighter, its better-trained and more experienced airmen and its radar-directed combat air patrols.

In the end Admiral Ozawa received orders from Toyoda to withdraw from the Philippine Sea. U.S. forces gave chase, but the battle was over.
The four Japanese air strikes involved 373 carrier aircraft, of which 130 returned to the carriers, and many more were lost on board when the two carriers were sunk on the first day by submarine attacks. After the second day the losses totaled three carriers, more than 433 carrier aircraft, and around 200 land-based planes. Losses on the U.S. side on the first day were only 23, and on the second 100, most of them resulting from the night landings.

The losses to the Japanese were irreplaceable. Of the Japanese naval air arm, only 35 out of Admiral Ozawa's 473 planes were left in a condition fit to fly. In the Battle of Leyte Gulf a few months later, their carriers were used solely as a decoy because of the lack of aircraft and aircrews to fly them.
