torpedo plane. This day of aerial combat became known as the "Marianas Turkey Shoot". With Japanese air opposition wiped out, the US carrier planes sank , two destroyers, and one tanker and damaged others. Two other carriers, and , were sunk by submarines. Indianapolis returned to Saipan on 23 June to resume fire support and six days later moved to Tinian to attack shore installations (see Battle of Tinian). Meanwhile, Guam had been taken, and Indianapolis became the first ship to enter Apra Harbor since early in the war. The ship operated in the Marianas for the next few weeks, then moved to the Western Carolines, where further landings were planned. From 12 to 29 September, she bombarded Peleliu, in the Palau Group, before and after the landings (see Battle of Peleliu). She then sailed to Manus Island, in the Admiralty Islands, where she operated for 10 days before returning to the Mare Island Naval Shipyard in California for refitting. 1945 Overhauled, Indianapolis joined Vice Admiral Marc A. Mitscher's fast carrier task force on 14 February 1945. Two days later, the task force launched an attack on Tokyo to cover the landings on Iwo Jima, scheduled for 19 February. This was the first carrier attack on mainland Japan since the Doolittle Raid. The mission was to destroy Japanese air facilities and other installations in the Home Islands. The fleet achieved complete tactical surprise by approaching the Japanese coast under cover of bad weather. The attacks were pressed home for two days. The US Navy lost 49 carrier planes while claiming 499 enemy planes, a 10-to-1 kill/loss ratio. The task force also sank a carrier, nine coastal ships, a destroyer, two destroyer escorts, and a cargo ship. They destroyed hangars, shops, aircraft installations, factories, and other industrial targets. Immediately after the strikes, the task force raced to the Bonin Islands to support the landings on Iwo Jima. The ship remained there until 1 March, protecting the invasion ships and bombarding targets in support of the landings. Indianapolis returned to VADM Mitscher's task force in time to strike Tokyo, again on 25 February, and Hachijō, off the southern coast of Honshū, the following day. Although weather was extremely bad, the American force destroyed 158 planes and sank five small ships while pounding ground installations and destroying trains. The next target for the US forces was Okinawa, in the Ryukyu Islands, which were
