On 19 June 1944, "Enterprise" was one of four carriers of Task Group 58.3 under the command of Rear Admiral John W. Reeves' during the largest carrier aircraft battle in history: the Battle of the Philippine Sea. For over eight hours, airmen of the United States and Imperial Japanese navies fought in the skies over TF 58 and the Marianas. Over the course of two days, a total of six American ships were damaged, and 130 planes and a total of 76 pilots and aircrew were lost. In sharp contrast, American carrier aircraft, with a major assist from U.S. submarines, sank three Japanese carriers (, , and ), and destroyed 426 carrier aircraft, losses from which Japanese naval aviation would never recover.
