Pituffik Space Base
Pituffik Space Base (, bee-doo-FEEK; Greenlandic: [pitufːik]; IATA: THU, ICAO: BGTL), formerly Thule Air Base (, TOO-lee), is a United States Space Force base located on the northwest coast of Greenland in the Kingdom of Denmark under a defense agreement between Denmark and the United States. Denmark was a founding member of NATO in 1949, and the 1951 Greenland Defense Agreement allowed the United States to operate the base under a NATO framework, as long as both Denmark and the United States remain NATO members.
