Out of the two T-50 tanks developed by factory #174 and the Kirov factory, the one developed by factory #174 was accepted into service.
The Kirov factory proposes increasing the thickness of the armour on its tank to 60 mm and installing a 76 mm gun. This should increase the weight to 25.5 tons. The top speed will be 40 kph with a 300 hp V-4 engine.
Factory #183 reviewed the T-34 tank and is proposing building it with a torsion bar suspension. With 45 mm thick armour it would weigh 25 tons, or 28 tons with 60 mm of armour. It would be armed with a 76 mm gun and have a top speed of 50 kph with a 600 hp V-2K engine.
Comparing the two tanks, one can see that they have identical armour and armament. The difference in weight between the two tanks is not great. The T-34 is faster and has a greater power to weight ratio: 21.4 hp/ton vs 11.7 hp/ton.
It is senseless to have two tanks with the same purpose in production at the same time. This will make issues of usage and spare parts more complicated. The factory #174 T-50 tank already exists as a means of infantry support.
I consider it impractical to develop and produce a T-50 tank with 60 mm of armour, since:
- The T-34 tank with a torsion bar suspension has better characteristics.
- It's senseless to introduce additional types of vehicles into service.
- This work will distract the Kirov factory from its primary work.
