In the third session of the CIK of the USSR, the description of Soviet flag in the Constitution was changed, and article 71 was edited to be: 'The state flag of the Union of Soviet Socialist Republics consists of a red or scarlet field, and in the canton a golden sickle and hammer, and a red five-pointed star bordered in gold above them. The ratio of width to length is 1:2.' On 19 August 1955 "Statute on the State Flag of the Union of Soviet Socialist Republics" was adopted by a decision of the Presidium of the Supreme Soviet of the USSR. This resulted in a change of the hammer's handle length and the shape of the sickle. On August 15, 1980, a new edition of the "Statute on the State Flag of the Union of Soviet Socialist Republics" was adopted, which did not make any changes to the flag's description aside from removing the hammer and sickle on the reverse side of the flag. From this point on, the flag stayed in use with this design until the disintegration of the USSR on 26 December 1991, at which time it ceased to be a national flag and replaced by national flags of the post-Soviet republics.
