In terms of tanks, Germany must make-for-tat improvements, tank guns, Germany's existing 88mm guns, can penetrate the so-called heavy tanks of the Soviets, no matter how he designed a good bomb-avoidance shape, its weight is always there!

However, the Soviets used 152 mm guns and 122 mm guns, which posed a serious threat to German tanks, so protection was more of a concern for Germany than firepower.

Historically, the German armor steel is quite excellent nickel-chromium alloy steel armor, the Soviet T-34, even if it is a model with an 85 mm tank gun, can have a penetration depth of 120 mm, but even the German 100 mm armor can not penetrate, because of the quality of the armor steel.

But in the later period, due to the lack of resources, the Germans could not obtain these rare elements, and could only use the surface carburizing process to increase the quality of the armor, resulting in the later tank protection was significantly inferior to before.

Now that Germany has taken control of Western Europe and controlled the origin of various raw materials, there is no need to worry about resources for the time being, but it is not enough to have nickel-chromium steel armor.

After all, it is still a kind of steel armor, and if you want to continue to increase the protection power, you must take the road of increasing the thickness, so that the weight of the tank will continue to increase, and it will become a road of no return for repeated cycles.

Moreover, in the development of tanks, firepower is always the easiest to break through, 105 mm tank guns, the depth of penetration can almost reach 500 mm, and the model of Huaxia Magic Change, it is said that it has reached 700 mm.

What to do with tanks? Can it be more than 700 millimeters thick? This is, of course, a delusion, this kind of iron lump, an absolute nightmare for power designers.

Therefore, it can only be solved from the structure and materials, and this is composite armor!

The structure of ceramic composite armor and cream sandwich biscuit is similar, the panel layer is alloy steel with high hardness, the bottom layer is alloy steel with strong toughness, and the middle layer is composed of many ceramic balls, and the gaps between the balls are filled with glass fiber reinforced resin.

In this way, by the time a menacing armor-piercing projectile passes through the level of the "sandwich biscuit", the warhead has already become dull and a lot of energy is consumed. Then, the harder ceramic ball in the middle layer dissolves and dissipates the main impact of the warhead, and finally, when the armor-piercing projectile, which has lost most of its energy, hits the high-tenacity inner baseplate, it has no armor-piercing ability. This is the principle of bulletproof of composite armor.

In contrast, ordinary alloy steel armor is purely hard-hitting, without any technical highlights, it is harder than anyone! The armor is hard, if it is blocked, then the armor wins, the warhead is hard, it penetrates, then it destroys the tank, it's that simple.

From this point of view, under the same thickness, the bulletproof ability of composite armor is more than that of ordinary armor steel, and among them, the most critical is the ceramic ball.

The earliest application of ceramic armor can be traced back to 1918, after the end of World War I, when Major Never-Monroe Hopkins experimented with a layer of 1.6mm thick enamel on the surface of steel armor to greatly enhance the protective performance.

However, ceramic armor did not enter practical application, until after World War II, with the rapid development of tank gun penetration, and the protection ability lagged behind, no one remembered ceramic armor, in-depth research, to the sixties, finally entered the application stage.

The first to be applied is alumina ceramics, which have excellent performance, relatively low manufacturing costs, and a very thin ceramic layer can defend against small arms and ammunition.

Therefore, in Ciric's suggestion, alumina ceramics are put in the first place, it is relatively easy to achieve breakthroughs, and it is very light in weight and low in cost.

In this way, it can be used both as human armor and as an increase in the protection of the tank.

In addition to these, what tungsten carbide, boron carbide, silicon carbide and so on, all have various advantages and disadvantages, Krupp company technicians are still researching, and alumina ceramics have come out of the research results!

Composite armor, which is more needed by the German armored forces at the moment! Getting this news, Ciric was also quite happy: "You can bolt an additional layer of armor on the front end of our tank hull and turret to achieve higher protection capabilities!" Well, before March next year, we will complete the transformation of all the Tiger tanks we have already produced! ”

No matter how thick the armor of the tank is, additional armor makes sense. Historically, many German tanks were reserved for additional armor.

For example, after the invasion of the Soviet Union, Germany found that its existing tanks were not adequately protected, and immediately temporarily added 30 mm additional armor to the hull and turret front of the hull and turret in Type 3H, reaching a thickness of 60 mm, to help resist the British 2PDR, the Soviet 45 mm and the American 37 mm anti-tank guns.

And when the Tiger tank was produced, a reservation was already made.

As he spoke, Ciric suddenly came to his mind again: "When we add this layer of composite armor, we can design it as a wedge, well, like a milk hood." In this way, it can not only prevent armor-piercing bullets, but also have a very good protection effect against armor-piercing bullets. ”

Ciric remembered the Leopard 2 tank of later generations, and the added milk cover was very ingenious, and now, armor-piercing shells have also appeared, and for metal jets, gap armor is very suitable.

Hearing Ciric say the word milk cover, some of the designers present wanted to laugh, and then, Ciric took the pen and began to sketch out the plan on the spot, and they concentrated and listened carefully.

Soon, they nodded frequently, and Ciric's idea was quite good!

After talking about this plan, Ciric stood up: "Okay, now that I've said that, let's go to the factory and have a look!" ”

Rather than an empty report in the conference room, Ciric prefers to go to the factory to inspect in person and be with the front-line workers, which is more meaningful.

However, as soon as Ciric stood up, he saw Graf coming, and he leaned into Ciric's ear and whispered, "Ciric, Mussolini is here, and he wants to see you." ”

Mussolini? Ciric, of course, knew what Mussolini meant when he came looking for him, the battle in Greece had been lost, and he wanted the German army to help him get his grounds.

For the sake of pig teammates, slowing down the pace of their own attack on the USSR? Of course not, I am not Hitler, and I have great respect for Mussolini as a mentor.

"Let him wait." "I have more important work to do. ”
