Adak Island (, ) or Father Island is an island near the western extent of the Andreanof Islands group of the Aleutian Islands in Alaska. Alaska's southernmost town, Adak, is located on the island. The island has a land area of , measuring long and wide, making it the 25th largest island in the United States. Due to harsh winds, frequent cloud cover, and cold temperatures, vegetation is mostly tundra (grasses, mosses, berries, low-lying flowering plants) at lower elevations. The highest point is Mount Moffett, near the northwest end of the island, at an elevation of 3,924 feet (1,196 m). It is snow covered the greater part of the year. Adak is its largest and principal city. The word Adak is from the Aleut word adaq, which means "father". History Adak Island has been the home to Aleut peoples since antiquity. Russian explorers in the 18th century also visited the island but made no permanent settlements.

Adak Island was chosen as the site of an airfield, and flight operations began in September 1942. On May 11, 1943, four days after the initial invasion date was delayed by bad weather, American soldiers landed on Attu Island and defeated the Japanese garrison there, at the cost of 2,300 Japanese and 550 American lives. Expecting a similar battle for Kiska Island, U.S. and Allied soldiers landing there August 15, 1943, found the occupiers had been stealthily evacuated by Japanese naval forces since the end of May, 1943. Even so, over 313 Allied soldiers died from friendly fire, mines, and other anti-personnel devices during Allied operations to take back Kiska. In 1953, remains of 236 Japanese dead who had been buried in Adak Cemetery were reburied in Japan's Chidorigafuchi National Cemetery. After the war was over, the approximately 6,000
