The Air Force Command and Control Headquarters was formed in Tallinn on 13 April 1994. In February 1993 the German government donated two Let L-410UVPs transport aircraft. In October 1994 three Mi-2 helicopters were delivered, followed by four Mi-8s in November 1995. Initially tasked with ground-based, air surveillance and air defence using only old Soviet radars and AAA equipment, on 15 May 1997 the Air Force moved into the former Soviet Su-24 base at Ämari, south of Tallinn. In 1997–98 two of the Mi-8's were upgraded.
