An air army was a type of formation of the Soviet Air Forces from 1936 until the dissolution of the USSR in 1991. Air armies continued to be used in the successor Russian Air Force until 2009. The first three Air Armies, designated 'Air Armies of Special Purpose' were created between 1936 and 1938. 2nd Air Army was created on 15 March 1937 in the Far East. Somewhat later, the 3rd Air Army was created in the North Caucasus Military District. However, air armies were excluded from the organisational reform of the air forces approved on 25 July 1940. On 5 November 1940, the three existing air armies were reformed as the long range bombardment aviation of the Stavka of the Red Army due to poor combat performance during the conflict with Finland.
