In the 1930s a regional hospital was built in Tanana, and the Native Village of Tanana was officially chartered by the U.S. Bureau of Indian Affairs in 1939. The hospital served people throughout most of the rural northern regions of Alaska until 1982. During World War II Tanana's airfield was one of the stops for aircraft en route to Russia as part of the Lend-Lease program. Postwar, a White Alice communications site was built on a hill nine miles behind Tanana, as a part of the Cold War Era's Distant Early Warning system (DEW-Line). Also during the 1950s the mission closed and the indigenous families still living at the mission site moved down to the main town.
