Description: The USDB, Fort Leavenworth, Kansas 66027, originally designated the U.S. Military Prison, was established by Congress in 1874 and has been in operation at Fort Leavenworth since May 15, 1875. This military prison has the distinction of offering the first vocational training program established in this country for prisoners. The USDB is the only long term prison in the Department of Defense, incarcerating personnel from all branches of the service. The last hanging at the USDB was Pvt. John A. Bennett in April 1961.
The new Disciplinary Barracks was completed in 2002. The new 521-bed facility will be considerably smaller than the original one which at one time housed more than 1,000 inmates.
