"Their tanks are 20-ton, 50mm tank guns, which have very good performance, especially their protection capabilities. Our existing tanks cannot penetrate them at all. We must have new tanks." Major Belotov said first.

As a tank soldier commander who returned from the Spanish Civil War and had not been cleaned up, Belotov naturally received high attention. In the Spanish Civil War, Soviet tanks were simply defeated, and the senior commanders of the entire Soviet were quite shocked.

"So, we suggest that our tanks must resist direct fire from 50mm cannons at close range and oblique fire from 75mm cannons at medium and long distances." Belotov continued.

The short distance is within 500 meters, and the medium and long distance is within 500 meters. The opponent is equipped with 50mm tank guns and a small number of 75mm guns. Therefore, our own tanks must develop new tanks according to these indicators in order to give the tank soldiers confidence.

"It seems that we must develop new tanks." Stalin, who was holding a big smoke pot in his mouth, had a gloomy face: "Do you have a good plan?"

At this conference, there were also designers from the tank industry.

In the 1930s, the Soviet Union had two tank production bases, both under the leadership of the General Administration of Automobile Armored Tanks of the Red Army, and the person in charge was i.a. Halevsky.

One of them is located in Leningrad, which is a production base composed of the Kirov factory and the Red October factory; the other is the Kharkov Locomotive Factory.

The former is responsible for producing tanks such as t-28, t-35 and t-26, while the latter is responsible for producing BT series fast tanks.

After hearing Stalin's question, Kokin spoke first.

Joseph Yakovlevitch Kotin, now the title is the chief designer of Leningrad Kirov factory. The three factories in Leningrad, namely Voroshilov factory, Bolshevik factory and Kirov factory, and the leader is the Kirov factory.

"We think that if we want to increase our tank protection, we must increase armor protection." Kokin said: "So, we decided to replace the existing T-28 tanks with a new engine and increase our armor protection."

Kokin talked freely. As a famous tank designer, his advantages were unique. For example, he was the son-in-law of Marshal Soviet Voroshilov! He often met Stalin and was highly valued by Stalin.

Now, after hearing Kojing's plan, Stalin nodded, increasing armor protection, increasing vehicle weight, and replacing a new engine, all of which are the right way.

Kejing reported for two full hours. He had three plans in total, each of which was introduced in detail.

It was not until his introduction that it was the Kharkov factory.

Mikhail Ilyich Koshkin, who became the chief designer of the tank design studio of the Kharkov factory last year, had a very different idea from Kojing.

"We believe that just increasing the weight will lead to other problems, such as our current T-35 tank, with a total weight of 52 tons, but various mechanical failures are emerging one after another. We believe that the weight of the tank, controlled within 30 tons, is in line with our current technical level."

This made Kojing quite dissatisfied.

In fact, Koshkin was not wrong. The heavy multi-turret tank of the T-35 is the pride of the Soviets. Every time the Moscow military parade is parade, it causes a sensation in the Red Square.

However, that's all, the total output of this kind of tank is less than 100. Apart from attracting attention during the military parade, it has no combat capability and many failures. It can be said that this kind of tank is just to put on airs and shows the advanced nature of Soviet tanks, which is almost the same as that of the Pet-8.

Koshkin was still relatively young and could not talk about the tricks in the officialdom. He didn't know that just his remarks had already been on Kojing's blacklist.

"So, our design plan is to increase protection by using bulletproof shape and inclined armor. We observed that the German tanks use tilted decks. Under the same weight, tilted armor can have better protection capabilities. We also intend to do this, and we need to use casting to get better bulletproof shape."

Koshkin submitted his design plan, codenamed a-32, and after Major Belotov received this design plan, he agreed in his heart, but because of Kojing's face, it was not convenient to express his opinions immediately.

It is definitely better to change the appearance by just increasing weight!

"Our tank is a universal tank, combining the high speed of BT series tanks, the firepower of T-28 and the compactness of T-26. The emergence of a universal tank can completely save the cost of the troops." Koshkin continued.

"The tank you designed does not look like it is not dual-purpose for wheels?" Kojing suddenly discovered something and asked Koshkin.

In this era, it is still advocated for dual-purpose use of wheels and footwear. All the Soviet BT fast tanks were like this. If the tracks were removed, they would be wheels. Walking on the road, they could cross-country after installing tracks. They seemed to be all-round, but in fact, they were useless.

The army rarely uses the wheel mode of the BT tank, which is too troublesome, and at the same time, this design increases the complexity of production and its own weight.

Koshkin expressed his ideas: "We have observed that German tanks have abandoned the dual-purpose use of wheels and tracks, and all used track chassis. We think this is our direction of development."

Hearing the people on the side, Marshal Voroshilov, a member of the Soviet People's Committee on National Defense, firmly opposed the pure tracking: "We must not give up the wheeled high-speed marching, which will cause our troops to lose the ability to maneuver quickly!"

Stalin held a big smoke pot in his mouth and never spoke.

To be fair, Stalin did not particularly agree with pure crawler style. However, since all Germans are crawlers now, it means that this method is beneficial. Otherwise, how could the Germans use it like this?

However, what is suitable for Germany is not necessarily suitable for the Soviet Union. After all, the Soviet Union's territory is too vast, and a high-speed wheeled plan is also indispensable before entering the war zone.

"Comrade Koshkin, I need you to prove the superiority of pure tracking solutions," Stalin said. "You can make a combination of wheel tracks at the same time, and compare the two."

In this way, Stalin made the decision, and Koshkin also frowned. Combined with the wheels and footsteps, his own tank did not reserve this part of the space! Such improvements are meaningless.
