Osoaviakhim (Societies of assistance to defense and aviation-chemical construction)
Societies of Assistance to the Defense and Aviation-Chemical Construction of the USSR (Osoaviakhim) was established in 1925-1926 via the merger of Dobrokhim, the Voluntary Society of Friends of Chemical Defense and Chemical Industry and of ODAF, the Society of Friends of the Air Force. In 1948, Osoaviakhim was re-structured into three societies: the Voluntary Society of Assistance to the Army (DOSARM), the Voluntary Society of Assistance to the Air Force (DOSAV) and the Voluntary Society of Assistance to the Navy (DOSFLOT). The three were reconstituted in August 1951 into the Volunteer Society for Cooperation with the Army, Aviation, and Navy (DOSAAF).
