The 1st Air Defence Division is a military formation of the Russian Aerospace Forces. It traces its history to a corps of the Soviet Air Defence Forces, and later the Russian Air Force. The corps was headquartered at Severomorsk and was part of the 10th Air Defence Army from 1960 to 1994. It was formed as the Northern Air Defence Corps in 1957 and was assigned the designation "21st" three years later. It became a brigade in 2009 and was converted into a division in 2014.
