The BT-SV was an experimental Soviet light tank. In 1936, Soviet engineer Tsiganova proposed a new high-speed (BT) light tank based on the BT-7. The design was to incorporate sloped armor similar to the T-34, which was also being developed at the time, and a transmission identical to that of the BT-7. Only 2 prototypes were built, both of which saw field testing. The vehicle never saw mass production, and resources were instead focused on the production of the T-34 medium tank.
