The T-43 medium tank was a prototype Soviet medium tank developed during the Second World War as a possible replacement for both the T-34 medium and KV-1 heavy tanks. The project's aim was to build a medium tank with heavier armour, but German advances in tank technology proved better countered by a more heavily armed T-34-85 and the T-43 was cancelled.
