The Ministry of Heavy Machine Building (Mintyazhmash; Russian: Министерство тяжёлого машиностроения СССР) was a government ministry in the Soviet Union.
The statute of the People's Commissariat of Heavy Machine Building was confirmed by a decree of the Council of People's Commissars on 23 April 1939.[1] On 5 June 1941, when the Ministry of Machine Tool and Tool Building Industry was organized, it was given jurisdiction over a number of main administrations formerly belonging to the People's Commissariat of Heavy Machine Building.[1]
With the reorganization of the Council of People's Commissars into the Council of Ministers in 1946, the People's Commissariat of Heavy Machine Building became the Ministry of Heavy Machine Building.[1]
