T-18M Light Infantry Tanks

USSR T018 Light Tank

Russia's T-18

After a special Tank Bureau was formed on May 6, 1924, a specification for a light tank was given. It was to weigh 3,000 kg, have a speed of 7.5 mph, 16 mm of armor, 37 mm gun, and with a crew of 2. During early 1925 the Red Army staff reviewed the specification and increased it to 5,000 kg.

The first prototype was called the T-16 and was finished in May 1927. Improvements to the engine and the length were completed in November 1927 and this was designated the T-18. The Revolutionary Military Council accepted the T-18 as a standard on July 6, 1927, even before testing was completed. It was called the Maliy Soprovozdieniya - Small Accompanying - One (MS-1).

It was produced at the Leningrad Bolshevik plant starting in 1928. This was the first Russian tank to be put into serial production. It was withdrawn from service in 1932 and given to the Ossoaviakhim, which as the military training organization.

It used rubber tired bogies. The engine was mounted traversely to save length and thus weight.

Communication was by flag.3

Usage

MS saw combat Kiev-Voronezh and Chinese Eastern Railway in 1929.

After the Germans invaded Russia, approximately 200 MS-1s were converted into T-18Ms mounting 45 mm guns.
