Soviet Class A Second Group
The Soviet Class A Second Group was the second and for a season third highest division of Soviet football, below the Soviet Class A First Group. The league was formed in 1963 by splitting away from the Class A and forcing the Class B of the Soviet football championship to downgrade to the third tier.
In 1970 the Soviet Class A was expanded even further adding additional tier to the top and downgrading the Soviet Class A Second Group to the third tier. In 1971 it was replaced with the Soviet Second League.
