T-18 light tank ,also called MS-1 (Russian: Maliy Soprovozhdeniya - Perviy), means "First Small Support" was the first Soviet-designed tank. Produced from 1928-31, it was based on the Renault FT, with the addition of a vertically sprung suspension. The T-18 and its derivatives were essentially unsuccessful designs, but they gave Soviet industry its first experiences in designing armoured vehicles, and in the meantime a number of foreign tank designs were available for production.
