Although the Estonian Air Force inherited a large number of former Soviet Air Force airfields in 1991 during the restoration of independence, most of them were disbanded within the early 90s due to non-existing need for such airfields. The Estonian Air Force has one active main air base in Ämari and occasionally uses a civilian airfield in Tallinn. The base houses the Base Operation Centre, Base Defence Operations Centre, a flight group, the Airfield Operations Group, Air Force Support Group and the Air Force Training Centre.
