I doubt this would be classified, so I’m just wondering where these F-22’s come from? Is there an air base on Attu?
Most likely Elmendorf near Anchorage. The other Air Force base in Alaska is Eielson up past Fairbanks.
Eareckson Air Station on the island of Shemya (near Attu) was closed as an active Air Force Station in 1994. The airport is still owned by the USAF and is operated for refueling purposes.
