The Vickers-Carden-Loyd light amphibious tank (designated the A4E11 and A4E12 by the War Office),[1] was a series of British experimental pre-World War IIlight tanks (resembling tankettes), which, although not taken into British service, were sold to a number of other countries which produced modified versions which were then taken into service.
Users
Foreign buyers included China (29 or 32 tanks),[2] Thailand, the Dutch East Indies (two delivered in 1937)[3] 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.[4] 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.
