Abstract
There is an opinion about the exclusively technical functions of the State Planning Committee in historiography. However, this institution played a significant role in the development of economic policy strategies and its implementation. Using the example of the conversion of the military industry in 1945-1950. the role of the State Planning Committee is shown as an important element of the state system. He was not a conductor of the decisions of the Stalinist leadership, but took an independent position on carrying out the conversion and limited the “opportunism” of the military-industrial departments. The determining factor was the personality of N.I. Voznesensky. Throughout the 1940s. he was a member of the leadership of all senior structures involved in economic management. The influence of the State Planning Committee on political decision-making was directly related to the career growth and strengthening of the administrative weight of its leader.
