The history of Fort Indiantown Gap dates to 1755, when the colonial government established several forts as defenses for White settlers against the
Susquehannock. Tensions had risen as the colonists encroached on the communal lands of the Susquehannock, who had long hunted and cultivated there. The Native Americans became willing allies against the British colonists as the
French and Indian War began. At the onset of the war, the Susquehannock attacked colonial frontier settlements, using the passes that existed in
Blue Mountain through
Manada Gap, Indiantown Gap, and
Swatara Gap. Because of these attacks, fortifications were established near Swatara Gap in northern Lebanon County, just east of present-day Fort Indiantown Gap, and near Manada Gap in Dauphin County. The name Indiantown Gap was fashioned from the Native American presence and geography. “Indiantown” is derived from the many Native American villages that existed in the vicinity of the installation, and “Gap” refers to the separation in the Blue Mountains through which the creek known as Indiantown Run flows.
Postwar From 1951 to 1953, during the
Korean War, the Gap again had a strategic role as the home of the
5th Infantry Division, whose mission was to train 32,000 troops as replacements for assignment to
Korea. In 1976, a section of Fort Indiantown Gap was selected as the new national cemetery for the states of
Delaware,
Maryland,
New Jersey,
Virginia, and
West Virginia. The Commonwealth of Pennsylvania donated the land for the site to the Veterans Administration. In 1980, the Gap again became a refugee camp when over 19,000
Cuban aliens were brought there for processing and sponsorship after the
Mariel boatlift. The last Marielitos were not released from the Gap until late 1981. Muir Army Airfield, which is home to the 28th Expeditionary Combat Aviation Brigade and the Eastern Army National Guard Training Site, is one of the busiest airfields in the U.S. Army. In 2021, EAATS was selected to be the first unit in the Army—active-duty, National Guard or Reserve—to receive a new variant of the UH-60 Black Hawk helicopter, the
UH-60V. FTIG is home to the headquarters of the Pennsylvania Department of Military and Veterans Affairs and the Pennsylvania National Guard as well as numerous other tenant organizations. In October 2019, it was announced that Fort Indiantown Gap would be home to the Keystone State ChalleNGe Academy, a residential educational program for at-risk youth that is part of the National Guard's
Youth ChalleNGe Program. The academy welcomed its first class of cadets in July 2022. For years an "open post," Fort Indiantown Gap began construction on the first of two access-control points, or gates, in December 2021. When the gates are finished and additional fencing is installed around the post's perimeter—projected for 2024—Fort Indiantown Gap will become a "controlled access" installation. == Tenant organizations ==
