The Israeli tank crews first began to use reactive armor to protect themselves in battle, which gave the Soviets a lot of confidence, and they began to develop various reactive armor to protect their own security.

Other countries in the West, on the contrary, are not very interested in reactive armor, and of course there is a reason for this.

Western tanks are very large in size, and their turrets are already welded turrets, so they mainly take the road of composite armor, especially the Chobham armor made by the British, although it is very bulky, but the protective effect is said to be very good, since the main armor is strong enough, naturally there is no need for additional reactive armor to increase protection.

The USSR was different.

The Soviet Union has a stubborn problem more than the big countries in the East, the Soviet Army is the most powerful, but also the most mainstream, they don't like to be flexible, they like the smooth shape of the turret casting, they also strictly limit the weight of the tank, they don't like the size of the tank to be too big, so it is difficult for the Soviet tank to continue to increase protection in terms of limited volume and weight.

So, the Soviets were also developing explosive reactive armor.

Once this kind of armor comes out, it is very simple to add additional protection to the tank, as long as you add a shelf outside the turret and directly screw the explosive reactive armor, it is the simplest and most practical, now, looking at the other party's cast turret, of course Qin Zhenhua has to start dissecting their armor protection.

Besides, it's no secret, according to the photos taken by NATO, the T-80 tanks used by the Soviet army have begun to install this additional module, and the eastern powers themselves have come up with several models of explosive reactive armor, and some have even begun to be marketed to the outside world as an upgrade kit for the 59 tank.

The T-80 is already there? Of course, the T-72 is no exception? Hearing Qin Zhenhua's words, Kartsev nodded: "That's right? We are currently working on a new generation of explosive reactive armor? Ready to be installed on our tanks, which can be used as additional armor protection? Protection of tank crews. ”

Now, the T-80 tank, although already using explosive reactive armor? The product, codenamed "Contact"-1, is a mature and well-designed explosive reactive armor. Its outermost layer is a thinner metal casing? Inside is a working component composed of a throwing plate thrown outwards and a backplate, explosives, and fixes thrown inward.

When fighting armor-piercing projectiles that use metal jets, it has a good protective effect and can destroy powerful metal jets, if converted? Can provide armor-piercing shells in excess of 400 mm? Let this weapon completely lose the ability to penetrate tanks.

However, it can only be resistant to armor-piercing bullets, increasing protection by tearing the metal jet, interfering with its path, destroying the principle of its material, but? In the world, the mainstream armor-piercing weapon is already a tail stabilized deshelling armor-piercing projectile. Want to defend against this weapon with explosive reactive armor? Isn't it easy, explosives are not sensitive to ordinary impacts? It can only be detonated by increasing the temperature, but the speed of the armor-piercing rod is only 1/5 of that of a metal jet? difficulty in effectively detonating explosive reactive armor; And? Metal jets with high velocity but low density? It is easy to be interfered with or destroyed, but the armor-piercing rod is a high-strength hard guy, and it is difficult for an ordinary throwing plate/backplate to break such a hard penetrating body, so it is not easy to use it against armor-piercing bullets.

However, the military R&D personnel of the Soviet Union were quite smart, and when they encountered problems, they should find a way to solve them.

After continued research, the new type of contact-5 explosive reactive armor unit has also been made in the Moscow Institute of Iron and Steel Materials, the design idea of this module is also very ingenious, with a high-hardness steel shell wrapped with 3 pieces of explosive reactive armor units similar to "contact"-1, each unit has a 10~15 mm thick throwing plate and a back plate, so that when penetrated by the armor-piercing rod, the reverse movement of the throwing plate and the backplate of the "contact"-5 and the upper and lower steel shells together to complete the destruction process of the armor-piercing rod.

The principle of this reaction is somewhat similar to that of restraint composite armor, and the research effect is not bad.

However, at the moment it has not yet been equipped with tanks, after all, it is still a new product, and in recent years, the country's financial expenditures have gradually shrunk, and funds for the army have begun to gradually become insufficient. Moreover, after attaching the explosive reactive armor, the dead weight of the tank will increase, and if the power of the tank engine is not increased, it will lead to a decrease in the mobility of the tank.

Therefore, the lower Tagil side plans to increase the power to 920 horsepower after the newer B-92 engine is built, and then use this device.

Now, Qin Zhenhua's words are a kind of temptation, no matter how they brag, when pouring the turret, ceramic balls are used in the middle, and it is still far from enough to rely on the protection of the turret itself, so as soon as Qin Zhenhua said this, Kartsev's face tightened, and then relaxed, and said: "Yes, we plan to hang explosive reactive armor on it, it is a great invention of ours, and it is a revolutionary achievement in the history of tank development. Just like when our T-64 tank first used composite armor. ”

At any time, one must not forget to boast, moreover, the Soviets had the capital to boast.

Since the beginning of the Cold War, the Soviets' tank sea has always been a nightmare existence of the West, and when the T-64 was born, it was at least ten years ahead of the West.

It uses a 125 mm tank gun, an automatic loader, etc., all of which are revolutionary, and its protection is not weak, using self-developed composite armor.

Of course, this armor can only be used on the hull, not on the turret, but at the time of casting, some ceramic balls are mixed in it.

Now, after showing off, he changed the topic again: "I don't know how the big countries in the East solve the problem of protection, is the main armor and the explosive reactive armor used together?" ”

While chatting, both sides were testing each other, using each other's words to see what they could say, in this process, Qin Zhenhua has always been in a state of non-stop speech.

"We believe that explosive reactive armor is just a transitional product, and if we want to really achieve the perfect defense of the tank, we should take the initiative to counterattack, when the opposite shell comes, we fire an interceptor missile and directly blow up the opposite shell, so that our tank will be absolutely safe."
