The T-18 light tank (also called MS-1, Russian: малый сопровождения, первый, romanized: maliy soprovozhdeniya, pearviy, "Small [Vehicle for] Support, First [type/example]") was the first Soviet-designed tank. Produced from 1928 to 1931, 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.
