NCI Agency CIS Support Unit (CSU) Ramstein is located at Ramstein Air Base in Rhineland Pfalz, Germany. As part of the Service Operation Directorate, it is responsible to the General Manager for delivery of Communications and Information Systems (CIS) services to HQ Air Command, including support for Ballistic Missile Defense (BMD) system and Air Policing Systems. CSU Ramstein also provides support to Torrejon (Spain), Uedem (Germany) and Poggio Renatico (Italy), detachments subordinate to HQ AIRCOM.
Ramstein Air Base is the largest North Atlantic Treaty Organization (NATO)-controlled air base on the European continent. Designed by French engineers, built by Germans, and operated by Americans, Ramstein maintains its long-standing tradition of international collaboration.
The current base was originally built in the beginning of the Cold War. From its inception, Ramstein was designed as a NATO command base. In 1957, Ramstein provided support for NATO's HQ Fourth Allied Tactical Air Force. With US Air Forces in Europe’s (USAFE) arrival in 1973, Ramstein entered a period of expansion. It is interesting to note that the KMC (Kaiserslautern Military Community) during the 1950s to the early 1990s had an average population of 110,000 Americans, outnumbering Germans in the nearby city of Kaiserslautern during this period.
Allied Air Forces Central Europe was established at Ramstein on 28 June 1974. Ramstein subsequently provided support for other headquarters, including the 322nd Airlift Division which arrived on 23 June 1978, and Strategic Air Command's 7th Air Division, which arrived on 1 July 1978. In December 1980, HQ Fourth Allied Tactical Air Force was moved from Ramstein to Heidelberg and co-located with HQ Central Army Group. Ramstein Air Base went on to become a large multi-national NATO center, in addition to the USAFE's headquarters. As of 28 June 1974 it also housed the new NATO headquarters of the Allied Air Forces Central Europe (AAFCE).
Today, the base is home to HQ Air Command, the only NATO command unit on Ramstein Air Base. Also, it is the home to HQ USAFE and HQ AFAFRICA (US Air Forces Africa).
