The medium tank T-24 was created after improvement of a design T-12. In September 1929 assembly at once of three machines began. In July 1930 the first tank was sent on tests. Accepted by the army for duty, serial production began the same year. The 1930/31 plan was production of 200 units, but only 25 were made in all, due to difficulties with the financing. In the fall of 1941 only one complete T-24 tank was left and possibly sent to the front.
