Armament and Protection

  • Main Armament: One 130 mm S-70 L/50 rifled tank gun (a conversion of a naval gun).
  • Loading System: Features an assisted loading mechanism (autoloader) using a conveyor belt, allowing for a high rate of fire (6–8 rounds per minute).
  • Secondary Armament: An exceptionally heavy battery, including two 14.5 mm KPVT heavy machine guns (one coaxial, one roof-mounted AA) and six 7.62 mm RP-46 machine guns (various forward and rear mountings).
  • Frontal Armor (Hull): 150 mm, steeply sloped at 65 degrees in the “pike nose” configuration, designed to defeat German 12.8 cm guns.
  • Frontal Armor (Turret): Up to 250 mm on the turret face and 350 mm on the mantlet, with heavy angling.

Powerplant and Mobility

  • Engine: M-50T V12 water-cooled diesel engine (based on a naval engine).
  • Power Output: 1,050 hp (780 kW).
  • Maximum Road Speed: Up to 60 km/h (37 mph), which was exceptionally fast for a heavy tank of its size.
  • Power-to-Weight Ratio: Approximately 15.4 hp/tonne, giving it superior mobility compared to many contemporary heavy tanks.
  • Suspension: Advanced torsion bar suspension with hydraulic shock absorbers for a smooth ride.
  • Cancellation Reason: Despite successful trials, the tank was deemed too large, complex, and heavy for rail transport and mass production in the post-war environment, leading to the adoption of the lighter T-10 (IS-8).
