FCI (formerly USP) Leavenworth, a civilian facility, is the oldest of three major prisons built on federal land in Leavenworth County, Kansas. It is separate from, but often confused with, the
United States Disciplinary Barracks (USDB), a military facility located on the adjacent
Fort Leavenworth army post. Located north of the FCI, the USDB is the sole maximum-security penal facility for the entire
United States military. USP Leavenworth was the largest
maximum-security federal prison in the United States from 1903 until 2005, when it was downgraded to a medium-security facility. The former civilian penitentiary was built by prisoners from the original USDB. Additionally, the military's medium-security
Midwest Joint Regional Correctional Facility (JRCF), located southwest of the new USDB, opened in 2010. The USDB and JRCF operate independently from FCI Leavenworth. The prison has been profiled in
