Although often considered the westernmost place in the United States due to its location relative to the rest of the country, Attu Station is actually one of the easternmost points in the United States, located at 52°50′47″N 173°11′10″E / 52.84639°N 173.18611°E / 52.84639; 173.18611Coordinates: 52°50′47″N 173°11′10″E / 52.84639°N 173.18611°E / 52.84639; 173.18611, on the opposite side of the 180th meridian from the rest of the United States.
After the Japanese invasion of Attu Island and the battle to retake it, the United States government constructed a LORAN station on the southern tip of the island, at Theodore Point. The equipment to build the station came from Holtz Bay and was ferried on barges and landing craft to Baxter Cove, about one mile (1.6 km) east of the station. Bulldozers were used to cut a road from Baxter Cove to Theodore Point.
In 1960 the station was moved to Casco Cove, near the former United States Navy base at Massacre Bay. Later it was moved to Massacre Bay. LORAN Station Attu ceased transmission of the LORAN signal Feb. 8, 2010 and the Russian-American signal ceased on August 1, 2010.
