Ellsworth Air Force Base (EAFB) is a U.S. Air Force Air Combat Command base six miles east of Rapid City, South Dakota, next to the town of Box Elder. EAFB covers about 4,858 acres in Meade and Pennington counties. The base includes runways, airfield operations, industrial areas, housing and recreational facilities. EAFB is surrounded by farming and ranching lands, rural housing and light commercial activities. military jet taxiing EAFB began in July 1942 as the Rapid City Army Air Base, a training facility for B-17 bomber crews. In 1948, as part of the 28th Strategic Reconnaissance Wing, it became a permanent facility. Historically, EAFB has been operations headquarters for a variety of aircraft, as well as the Titan I intercontinental ballistic missile system and the Minuteman missile system. Presently, the 28th Bombardment Wing (B-1B bombers) is the host unit of EAFB. A half century of military activities left contamination on the base and on private land beyond its boundaries. EPA added EAFB to its National Priorities List (NPL) on August 30, 1990. The Air Force, EPA, and the state of South Dakota have worked as partners to clean up EAFB.
