K. I. Sawyer Air Force Base, Former Air Force base in Marquette County, Michigan.
K. I. Sawyer Air Force Base is a former military installation in Michigan's Upper Peninsula with an active regional airport, featuring buildings that once served military operations and personnel. The airfield remains in use for commercial flights, while the grounds contain former barracks, hangars, and support structures from its operational days.
Built in 1944, the base served as a Strategic Air Command facility during the Cold War era until it closed in September 1995. This 50-year span shaped military operations and employment patterns across the Upper Peninsula during one of the nation's most tense historical periods.
The site shaped life in this part of Michigan for generations, with military personnel and their families leaving a mark on the community. This long presence influenced how the region developed and how people here built their everyday routines.
You can reach the site through Sawyer International Airport, which has regular service to surrounding regions. Before visiting, check what areas are open to the public, as parts of the former base still have restricted access for safety or cleanup work.
The grounds are undergoing environmental remediation focused on PFAS contamination in specific zones across the former installation. This cleanup work is part of broader efforts at military sites nationwide to address pollution from decades of operations.
