Soviet industrialization officially ran from May 1929 to June 1941, though historians date its end differently. Some mark the last pre-war year of 1940, others the year before Stalin's death in 1952, and by the measure of industry's share in gross domestic product, the Soviet economy did not reach levels typical of industrialized countries until the 1960s.
The GOELRO plan, approved by the 8th All-Russian Congress of Soviets in December 1920, was a long-term electrification program covering eight major economic regions and calling for thirty district power plants with a combined capacity of 1.75 gigawatts. Designed to run ten to fifteen years, it laid the infrastructure foundation for later industrialization. By 1932, electricity generation had increased nearly seven times over 1913 levels, from 2 to 13.5 billion kilowatt-hours.
American firms were central to major Soviet industrial projects. In February 1930, the Soviet government signed an agreement with Albert Kahn, Inc. worth two billion dollars, covering designs for more than five hundred industrial facilities. The Magnitogorsk Metallurgical Plant was designed and supervised by Arthur G. McKee and Co. of the United States, and the DneproGES hydro turbines were purchased from General Electric and Newport News Shipbuilding.
Steel production rose from 4.3 million tons in 1928 to 5.9 million tons in 1932, and coal output climbed from 35.5 million to 64.4 million tons over the same period. Stalin reported at the 17th Congress in January 1934 that heavy industry had fulfilled the plan by 108 percent. By the end of the second five-year plan, the Soviet Union ranked second in world industrial output, behind only the United States.
The Stakhanovist movement began in 1935, named for mine worker Alexey Stakhanov, who on the night of the 30th of August 1935 reportedly completed 14.5 shift quotas. A number of historians note that records were largely staged and relied on assistants, and critics including Trotsky argued the movement was a continuous productivity-extraction method previously associated with Frederick Taylor and Henry Ford. Because wages tracked output, Stakhanovists earned several times the industrial average, generating hostility from other workers.
As of the 1st of January 1932, the Red Army held 1,446 tanks and 213 armored vehicles. By the 1st of January 1934, those numbers had grown to 7,574 tanks and 326 armored vehicles, which exceeded the combined tank strength of the United Kingdom, France, and Nazi Germany at that time.
