| Notes | With the success of the SU-152, it was decided to build an improved model utilising the chassis of IS tank and this was to have better armour and retain the same 152mm heavy howitzer. It was a better vehicle then the previous SU-152 and made good sense to up-grade from the old KV-1 chassis to the new IS chassis. It was issued in a similar way as the previous models and to independent heavy artillery regiments. |
