During World War II, Nome was the last stop on the ferry system for planes flying from the United States to the Soviet Union for the Lend-lease program. The airstrip currently in use was built and troops were stationed there. One "Birchwood" hangar remains and has been transferred to a local group with hopes to restore it. It is not located on the former Marks Air Force Base (now the primary Nome Airport); rather it is a remnant of an auxiliary landing field a mile or so away: "Satellite Field". In the hills north of the city, there were auxiliary facilities associated with the Distant Early Warning system that are visible from the city but are no longer in use.
