Design
The Soviets were not fully satisfied with the Carden Loyd design and made a number of changes before putting it into mass production under the designation of T-27. Compared with the British original, the hull was larger, the running gear was improved and the weapon mount was modified to take a Soviet 7.62 mm

. A number of other changes were made by Chief Engineer N. Kozyrev and Lead Engineer K. Sirken to improve the tankette's ability to cope with the Russian climate and terrain. It lacked any communication devices, as communication between vehicles was intended to be carried out using
signal flags.

The tankette was accepted into service on February 13, 1931. It was manufactured in two factories simultaneously, the Bolshevik factory in

, with each having about 50 tankettes. This figure was later reduced to 23 per battalion. The tankette was also intended to be air-mobile. In 1935, the Soviets experimented with transporting T-27s by air, by suspending them under the fuselages of
Tupolev TB-3 bombers.

. However, they fairly quickly became obsolete due to the introduction of more advanced tanks. The Red Army found them reliable and simple to operate, but the T-27 coped poorly with swampy and snowy terrain due to the narrowness of its tracks. It was also difficult to find crews, as the tankettes were so small that it was difficult to find crews of sufficiently diminutive stature. By the end of the 1930s the T-27 was relegated primarily to training use, with some being used as tractors to tow field guns.
