During the occupation of Norway by Nazi Germany, the Nazi authorities established a "concentration camp in the town of Bardufoss," as an annex to the Grini concentration camp.
Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Boulder Municipal is BDU (formerly 1V5) to the FAA and WBU to the IATA (which assigned BDU to Bardufoss Airport in Bardufoss, Norway).
Fighters from Bardufoss also had the task of providing aerial support for naval operations in the area, but failed to scramble in time to prevent the battleship Tirpitz from being sunk by Avro Lancaster bombers at Håkøya near Tromsø.
The Norwegian Aviation College college was established at Bardufoss Airport in 1992 as the world's northern-most flight school.
The Bardufoss concentration camp is located in Northern Norway in the municipality of Målselv.
The main effect of the raid was that the Germans moved 20-30 fighters to Bardufoss, 30 miles from Tromsø.
Throughout the Cold War, Norway enforced a policy to disallow allied aircraft to operate further north than Bardufoss and Andøya, in an effort to minimize tension with the Soviet Union.
