| Notes | The SU-100 (Samokhodnaya Ustanovka) was developed to replace the SU-85. Once the T-34/85 was available in large numbers, this virtually made the SU-85 redundant as both vehicles mounted the same calibre gun. The Soviets still required a tank destroyer so efforts were put in place to up-gun the SU-85 with a larger gun. The decision was made to mount the 100mm D-10S gun in place of the 85mm weapon and this along with improved frontal armour made for a powerful tank destroyer which could knockout both the Tiger and Panther. The SU-100 was issued in the same way as the SU-85. |
