Vickers-Carden-Loyd Light Amphibious Tank [Shanghai - Nanking DLC]

The Vickers-Carden-Loyd Light Amphibious Tanks, with two variants designated A4E11 and A4E12 by the British War Office, were tractor-based tankettes designed to be able to travel across calm waters at the speed of about 6 kilometers per hour.

Foreign buyers included China (29 or 32 tanks), Thailand, the Dutch East Indies (two delivered in 1937) and the USSR, with the latter producing some 1200 of the T-37A tanks developed from the A4E11/12. One tank with a licence was sold to Japan. Poland was interested in Vickers-Carden-Loyd amphibious tanks in the 1930s, but negotiations failed and instead the PZInż works started the PZInż 130 project, an indigenous design inspired by the British concept.
