**5073rd Air Base Group (5073 ABG) – Shemya Island**
The 5073rd Air Base Group (ABG) was a United States Air Force unit stationed at Shemya Island, located in the Aleutian chain of Alaska. Activated during the Cold War, the 5073 ABG provided operational support for strategic surveillance and reconnaissance missions, including radar and intelligence-gathering operations critical to monitoring Soviet activity in the northern Pacific region. The unit maintained and operated Shemya Air Force Station, supporting various tenant organizations such as the Cobra Dane radar system. The 5073 ABG was inactivated in the early 1990s as the U.S. military presence in the Aleutians was reduced following the end of the Cold War.
