In 1930, Antonov graduated from the Kalinin Polytechnical Institute in Leningrad. He continued to design gliders and in 1931 Antonov became the chief designer at the Moscow Glider Factory. During the next eight years, he designed 30 different gliders including the Standard-1, Standard-2, OKA-6 and the large "City of Lenin" glider. Due to a requirement that all pilots in the Soviet Union had to begin their flight training in gliders, Antonov was able to produce up to 8,000 gliders per year.
