The main task of the introduced command economy was to build up the economic and military power of the state at the highest possible rates, accompanied with the near complete elimination of private industry that had allowed under the NEP. At the initial stage, it was reduced to the redistribution of the maximum possible amount of resources for the needs of state-owned industrialisation. In December 1927, at the 15th Congress of the All-Union Communist Party (Bolsheviks), "Directives for drafting the first five-year national economic development plan of the Soviet Union" were adopted, in which the congress spoke out against super-industrialisation: the growth rates should not be maximal and should be planned so that failures do not occur. Developed on the basis of directives, the draft of the first five-year plan (October 1, 1928 – October 1, 1933) was approved at the 16th Conference of the All-Union Communist Party (Bolsheviks) (April 1929) as a complex of carefully thought-out and real tasks. This plan, in reality, is much more stressful than previous projects, immediately after it was approved by the 5th Congress of Soviets of the Soviet Union in May 1929, gave grounds for the state to carry out a number of economic, political, organisational and ideological measures, which elevated industrialisation in status of the concept, the era of the "Great Turn". The country had to expand the construction of new industries, increase the production of all types of products and start producing new equipment.
