Casco Cove Coast Guard Station (IATA: ATU, ICAO: PAAT) is a remote airfield on Attu Island in Alaska's Aleutian Islands, at Massacre Bay near the western end of the U.S. It supported a former U.S. Coast Guard LORAN station and lies in an area known for severe weather and WWII history. The field has no scheduled commercial service and is generally limited to government, military, or emergency use.
💡 Local Tip
Even in summer, expect horizontal rain, fog, and sudden williwaws; secure loose gear and do not plan tight turnarounds. The island's WWII relics and nesting seabirds are protected, so observe from a distance and leave everything as you find it.

There is no road, ferry, or scheduled airline service to Attu. Access is normally by chartered or military aircraft from Adak or Anchorage, or by expedition vessel, and all arrivals must be coordinated with land managers. Weather frequently delays flights, so allow extra days and have backup plans.
