JS-3 Stalin with 122mm BL-9 gun (WOT)

This hypothetical "World Of Tanks" JS-3 is fitted with the 122mm BL-9 Very High Power Gun. The BL-9 was also known as the 122mm OBM-50 designed for tank destroyers such as the ISU-152. A tank version, the 122mm OBM-51 was designed capable of 950m/s muzzle velocity although it was destined for the KV and not the JS tanks. Ultimately the penetrating effect of the 122mm D-25 was sufficient so the BL-9 was not developed further.
