Ellsworth Air Force Base (IATA code: RCA) is situated 16km north-east of Rapid City in South Dakota, US. The base is owned by the United States Air Force (USAF) and operated by the Air Combat Command (ACC). Approximately 7,490 military personnel reside at the base.

The base was chosen as the new ground control station by the USAF in May 2010 for training pilots on the MQ-9 Reaper drone, which is expected to fly in 2012.

Ellsworth base was built in January 1942 under the designation Rapid City Army Air Base (RCAAB) to train pilots on B-17 Flying Fortress aircraft. It began operations under the control of Second Air Force (2 AF) in July 1942. Base control was transferred to the Continental Air Force (CAF) in October 1945. The CAF was renamed as Strategic Air Command (SAC) in March 1946.

Barksdale Air Force Base (IATA code: BAD) is situated 7.6km south-east of Bossier City in Louisiana, USA.


The RCAAB was renamed as Rapid City Army Air Field in September 1946. It was finally renamed as Ellsworth Air Force Base in June 1953, in the honour of Brigadier General Richard E. Ellsworth who died in March 1953 during a routine exercise in Europe.

The base became home to space related infrastructure in October 1960. Three Titan I intercontinental ballistic missile (ICBM) launch complexes were built in 1962. Titan I missiles were demobilised in March 1965. An upgraded version, the LGM-30F Minuteman II missile, was activated at the base in October 1971.

The control of the base was transferred from SAC to the ACC in June 1992. The entire missile complex was inactivated in April 1994.

Construction of facilities at Ellsworth AFB

"The RCA serves as the headquarters for the 28th Bomb Wing (28 BW) which can carry out bombing operations using B-1B Lancer bombers."

Construction of the runway, quarters and offices at the base were completed in October 1942. Five hangars were constructed in 1942. Three bituminous runways paved with concrete were built in 1943 to operate heavy bomber units. The construction of additional concrete areas, structures and roads was finished in September 1945.

Major facilities were modernised in 1948 to accommodate B-29 Superfortress aircraft. The medical facility was built in May 1956.

Dean Kurtz Construction was awarded a $12.1m contract by the USAF in August 2009 to renovate three existing access gates (Patriot, Bismarck and Liberty) with advance guard houses and security measures. The upgraded Patriot gate was opened in July 2010. Bismarck and Liberty were inaugurated in August 2010 and 2011 respectively.

A 54,000 square feet civil engineering administrative facility was built by Sampson Construction in June 2010. It is a two-storey steel structure which houses command and office centre. It was accredited with LEED Silver Certification by the US Green Building Council in August 2011.
