# List of military installations in Michigan

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 km$^2$), Camp Grayling - 147,000 acres (590 km$^2$)).
