Much of Aroostook County's economy was dominated by military spending through the Cold War. Limestone Army Air Field was built in Limestone, Maine in 1947. It was renamed Loring Air Force Base (AFB) in 1953 as the home of the Strategic Air Command (SAC) 42d Bombardment Wing operating Convair B-36 Peacemaker bombers. Aroostook County was chosen due to its strategic location as the closest point in the Continental United States to the Middle East and Europe including the Soviet Union west of the Ural Mountains. Loring AFB could accommodate one hundred of these large bombers; and had both the largest fuel storage capacity, at , and the largest weapons storage capacity, at 4700 tonnes NEW, of any SAC base. The 42d Bombardment Wing at Loring operated Boeing B-52 Stratofortress bombers until the 1991 Base Realignment and Closure Commission recommended closure and the base closed in 1994.
