bringing into service is the Bölkow Bo-150 in the version as anti-tank helicopter. The unit being stationed the longest at Celle was the Heeresfliegerstaffel 7 (Army Aviation Squadron 7). It was relocated from Rheine to Celle in 1971. In 1968 it had become a battalion but three years later, on its move to Celle, it was redesignated again as a squadron. The unit was equipped with the Alouette II liaison and reconnaissance helicopter and was disbanded in 1994. At the beginning of the 1970s the strength of the German Army Aviation Corps considerably increased when more manpower and material was allocated to it. In Celle Heeresfliegerregiment 10 (Army Aviation Regiment 10) equipped with Bell UH-1D was the first of these larger units, which would become the new standard. In 1979 a second regiment, Heeresfliegerregiment 16 (Army Aviation Regiment 16), equipped with anti-tank helicopters was founded at Celle. Since the air base was too small to house two regiments, Heeresfliegerregiment 10 subsequently relocated to Faßberg Air Base in 1981. Its coat of arms still shows the stylised Celle Castle. After the end of the Cold War Celle Air Base's ability for instrument flights was removed and the emergency landing strips on the motorways were abandoned. Following the removal of ILS as well as approach radar and the corresponding reduction within the ATC unit, the German Air Force finally left the base. Several smaller units were disbanded or relocated and only the Heeresfliegerregiment 16 remained as a flying unit at Celle. Within the framework of the restructuring of the German Army and in preparation of the introduction of the new helicopter types NH-90 and Tiger in 2002 and 2003, Heeresfliegerregiment 16 was disbanded and parts of the Heeresfliegerwaffenschule (German Army Aviation School), originally located at Bückeburg Air Base, were moved to Celle. At the same time the Heeresfliegerverbindungs- und Aufklärungsstaffel 100 (Army Aviation Liaison and Reconnaissance Squadron 100) and the Heeresfliegerinstandsetzungsstaffel 100 (Army Aviation Maintenance Squadron 100) were founded. With the commencement of training flights, Celle Air Base regained instrument flight ability and Bell UH-1D helicopters were again stationed on the air base. Since having been taken over by the German Army Aviation Corps, hardly any new buildings were erected on the air base. Some had to be pulled down due to their dilapidated state or due to environmental issues: a kitchen and dining room from the time of the Berlin Airlift
