Answer: Stalin's goal with his Five-Year Plans was to rapidly industrialize the Soviet Union and transform it from an agricultural-based economy to an industrial one.
Explanation: The plans were a series of nation-wide centralized economic plans that aimed to increase the country's output of heavy industry and to modernize the Soviet economy. The Five-Year Plans were implemented in three successive waves, from 1928 to 1941, and were successful in greatly increasing the country's industrial output, but at a great cost to the Soviet people.
