Brief overview
The People's Commissariat of Heavy Industry, known by the acronym NKTP, was founded in 1932 out of the Supreme Soviet of the National Economy and was responsible for all heavy industrial goods, including mining, machinery and defense goods.

The defense industry assets were separated in December 1936, with the creation of the People's Commissariat of the Defense Industry, and in August 1937 there was set up the People's Commissariat for Mechanical Engineering. In early 1939 the NKTP was divided into six separate commissariats.
