Overview
Attu is an island in the Near Islands (part of the Aleutian Islands chain). It is the westernmost point of the U.S. state of Alaska. The island became uninhabited in 2010, making it the largest uninhabited island to be politically part of the United States.
The Battle of Attu was the site of the only World War II battle fought between combatants on land in territory that is today part of the United States. The battlefield area is a U.S. National Historic Landmark.
Attu Station, a former Coast Guard LORAN station, is located at , making it one of the westernmost points of the United States relative to the rest of the country. (Technically it is in the Eastern Hemisphere, being on the opposite side of the 180° longitude line from the contiguous 48 states, and thus can also be considered one of the easternmost points of the country (a second Aleutian Island, Semisopochnoi Island at 179°46′E, is the easternmost location in the United States by this definition). For purposes of calendar date, the International Date Line, however, passes to the west of Attu Island, making it the westernmost place in the United States with the same date.)
In the chain of the Aleutians, the islands immediately to the west of Attu are the Russian Commander Islands, away (and on the other side of the International Date Line). Attu is nearly from the Alaskan mainland and northeast of the northernmost of the Kuril Islands of Russia, as well as being from Anchorage, from Alaska's capital of Juneau, and from New York City. Attu is about in size with a land area of , making it #23 on the list of largest islands in the United States. The population in the 2010 census was 20 people, all at the Attu Station, though all inhabitants left the island later in the year when the station closed. It then became the largest uninhabited island in the United States.
