List of military installations in Michigan

Naval Air Station Grosse Ile, on an island in the Detroit River, served to train Navy and Marine pilots and included a hangar for dirigibles.

Numerous military installations have been located in Michigan since the earliest French fortified trading posts appeared to modern National Guard bases. The Native Americans of the area established only temporary war camps although some were quite large (Chief Pontiac's 6-month encampment during the siege of Fort Detroit had around 1,000 warriors). The earliest French bases were quite small and short-lived. Later some installations would be in use for over a century (Fort Wayne, Fort Mackinaw) and spread over large areas (Fort Custer - 14,000 acres (57 km²), Camp Grayling - 147,000 acres (590 km²)).

Air Force Bases and Naval Air Stations

Wurtsmith Air Force Base was used to train Free French pilots in WWII and to house nuclear-armed B-52 bombers during the Cold War.

Michigan's northern location made it a good site for several Cold War air bases, especially Strategic Air Command B-52 / KC-135 bases. Numerous other sites around the state had antiaircraft gun or missile installations during the Cold War.
