The Eighth Five-Year Plan of the Union of Soviet Socialist Republics (USSR) was a set of production goals and guidelines for administering the economy from 1966 to 1970—part of a series of such plans used by the USSR from 1928 until its dissolution. "Directives" for the plan involved set high goals for industrial production, especially in vehicles and appliances. These directives for the Eighth Five-Year Plan was approved by the Central Committee of the Communist Party of the Soviet Union and by the 23rd Congress of the Communist Party of the Soviet Union but no final version was apparently ever ratified by the Supreme Soviet of the Soviet Union. Nevertheless, some of the changes envisioned were made.
