Historical Foundations

Pennsylvania’s military legacy spans centuries. Carlisle Barracks, established in 1757 as a British outpost, became a U.S. Army post in 1794 and hosted the Carlisle Indian Industrial School from 1879 to 1918 before becoming the U.S. Army War College in 1951. Fort Indiantown Gap, founded in 1931 as a state National Guard camp, was leased to the U.S. Army in 1940 for $1, transforming into a WWII training hub with over 1,400 buildings by 1941. It supported 150,000 troops and demobilized 450,000 post-war, reverting to National Guard control in 1998. These bases reflect Pennsylvania’s enduring defense contributions.

Economic Impact

Fort Indiantown Gap and Carlisle Barracks drive significant economic activity. Fort Indiantown Gap, spanning 18,000 acres, employs 2,500 personnel and generates $500 million annually in Lebanon County, supporting Annville and Harrisburg through training contracts and local spending. Carlisle Barracks, with 1,500 personnel, contributes $300 million to Carlisle’s economy, bolstering Cumberland County’s businesses. Families at both bases access 300 housing units, DoDDS schools (Carlisle Area School District, Annville-Cleona School District), and TRICARE clinics.
