"Conclusions
  1. The IS-3 tank presented by Kirov Factory passed the 500 km long proving grounds trials. It did not pass the 1000 km warranty trial due to the fan breaking at 810 km.
  2. The performance characteristics and reliability of mechanisms and assemblies of the IS-3 tank is equivalent to that of the mass production IS-122 tank.
  3. The ballistics trials of the IS-3 hull demonstrate its obvious advantages over the hull of the IS-122 tank.
  4. The modernized IS-3 tank is recommended for service under the condition that the defects in this report be resolved.
