Pituffik Space Base (pronounced bee-doo-FEEK), formerly known as Thule Air Base (pronounced too-lee), is located in Greenland—a country within the Kingdom of Denmark and inhabited by approximately 56,000 people. Greenland covers nearly 840,000 square miles; more than 80 percent is covered either by the ice cap or smaller glaciers. Pituffik SB is locked in by ice nine months out of the year, but the airfield is open and operated year round.
Pituffik SB, the DoD's northernmost installation, is operated by the 821st Space Base Group and part of Space Base Delta 1.
