Grissom Air Reserve Base is a United States Air Force base, located about 12 miles (19 km) north of Kokomo in Cass County, Indiana and Miami County, Indiana. The facility was established as Naval Air Station Bunker Hill in 1942 and an active Air Force installation from 1954 to 1994. Since then it is a joint-use civil airport/military base with the Grissom Aeroplex providing general aviation and charter service.
