Chapter 958 Our second generation, the world’s third generation!
"…The fire control system has a reaction speed of no more than X seconds. It has the ability to fire at moving targets during the day and at stationary targets and limited moving targets at night… It can launch strikes against typical enemy tank targets within 2500 meters during the day and no less than 2000 meters at night, and the hit rate meets the design requirements…"

These are the words that General Luo said in his report when summarizing the second-generation tank fire control system. If the Russians heard these words, they would cry with envy, not to mention the American M-60 that doesn't even have dual stabilization. The hit rate of that thing within 1000 meters is less than 50%, and it is even worse against moving targets.

Anyone who truly understands tanks would be excited by Mr. Luo’s words.

As for the ability of move-to-move, don't be fooled by the tank soldiers in S2 who can hit the target with move-to-move easily in TV and movies. In fact, that is all bullshit. The hit rate of move-to-move in S2 depends entirely on luck, and you need incredible luck to achieve it. It cannot be used as a technical and tactical indicator at all.

If you want to have a stable move-to-move hit rate without double stability, you can only rely on ShuangWen. From this point of view, it doesn’t matter since they are all ShuangWen.

The original 5DL before 5DL-D all had a disturbance-type fire control system, which was only slightly better than the S2. To be honest, the comrades in the army were even a little uncomfortable with the fire control system of this second-generation tank. It was too different from what they had practiced before.

Fortunately, our chief engineer Gao was very considerate and used the anti-stabilization image to leave a backup for manual gun control. The martial arts training previously was not in vain. Regarding this matter, the Air Force has something to say. Why are you so excited? Don’t you see that we also have to practice firing rockets and throwing iron bombs?
Then... they looked at the pile of whiteboard 5DLs in their hands and began to feel annoyed... This thing seems too outdated, right?
An army leader leaned over to Gao Zhendong and said, "Comrade Zhendong, isn't the difference between the Type 62 and the 5DL too big? It's hard for us to organize our training outlines and unify them..."

Gao Zhendong glanced at him and said with a smile: "You still need to practice the basic skills."

As if knowing that his complaint was a bit too outrageous, the army comrade also laughed: "Yeah, that makes sense, that makes sense."

Having said that, there was always something flashing in his eyes, probably he was thinking about something.

"…The new tank is equipped with a 105mm smoothbore gun. When firing a fin-stabilized discarding sabot armor-piercing projectile, the armor penetration depth of a tungsten alloy projectile at a distance of 2000 meters is no less than 440mm, and the armor penetration depth of a tungsten-inlaid all-steel projectile is no less than 320mm…"

The army comrades were almost bursting into smiles on their faces. The penetration might not seem very high, but this was a kinetic energy bullet, the most difficult type of bullet for tankers to defend against.

Unlike later armor-piercing projectiles that often have a penetration depth of more than 800 or 1000 mm, the penetration depth of fin-stabilized discarding sabot armor-piercing projectiles is difficult to reduce under the same armor technology background.

The difference between the 5DL gun and the 105mm gun is simply heaven and earth.

Some comrades know that this monster is inseparable from Gao Zhendong. ESR and self-tightening of the barrel, these two technologies have created this monster, and these two technologies came from Gao Zhendong's hands.

Gao Zhendong didn't think there was anything wrong with it. It was only slightly stronger than John Bull's L7-105 line, but compared with the L7-94 that we modified later, it was still far behind.

But it is already enough, not to mention the 440mm tungsten alloy warhead, even the 320mm all-steel bullet can hit almost all tanks in service. Even in the next ten or twenty years, there will not be many that can withstand it.

The leader of the Defense Work Committee turned around and smiled at Gao Zhendong, saying, "The all-steel bullet you proposed has greatly lowered the threshold for using this gun. The comrades in the army should thank you."

The main reason is that tungsten alloy is too expensive. When the comrades in the army saw it, they thought that this thing was good but they couldn't afford it, and it was too exaggerated to use it in daily training. The lifespan of the gun was not long, and coupled with the cost of ammunition, this tank was very expensive to use.

At this time, they remembered that when the second-generation tank was being discussed, Gao Zhendong said that in addition to tungsten alloy, all-steel bullets could also be developed, which could greatly reduce costs. So this all-steel bullet with tungsten alloy embedded on the top came into being. After trying it out, hey, the effect was equally outstanding.

The comrades in the army also turned to look at Gao Zhendong with a look of appreciation and gratitude. Not only is it advanced for the sake of being advanced, but it also considers the cost of use and the overall effect at the same time. This is an excellent scientific research style.

"…The gun barrel life is no less than 1200 rounds when firing ordinary ammunition, and no less than 420 rounds when firing fin-stabilized armor-piercing discarding sabot rounds…"

Gao Zhendong suggested to Lao He and his team that they chrome-plate the inner barrel and combine it with other technologies to greatly increase the life of the gun barrel. Finally, they don't have to be so stingy and only use guns instead of cannons for training. At least they can fire a few live ammunition from time to time to test the quality.

Guns replacing cannons. Using guns with suitable ballistics to replace cannons during training can play a training role and save the life of the gun. This kind of gun may be a special inner-bore ballistic gun installed in the barrel, or it may be more crude. For example, we have seen training photos that showed a gun mounted on the barrel of a tank. That gun was either used to kill the enemy or to do this.

However, no matter how much you practice, you still have to fire a few live rounds to test it. The life of this gun has greatly reduced the concerns about the life of the gun in this kind of training. Now the army is most concerned about the life of APFSDS. They are not particularly concerned about grenades and armor-piercing shells, especially armor-piercing shells. Although the armor-piercing shells have been improved similar to the 61 fire, using new gunpowder, charge caps and other technologies, their armor-piercing power has reached more than 600 mm, which is still undefended by current tanks. However, the comrades of the army found a problem in the live-fire experiment.

Armor-piercing shells are not as accurate as APFSDS!
The latter's trajectory is straighter and lower, and its flight speed is faster, while the curvature of the armor-piercing projectile's trajectory is visible to the naked eye at a distance of 2000 meters.

This incident was also recorded at the World Tank Competition organized by Russia decades later. The Russians used armor-piercing shells to shoot at targets, and the trajectory was really ugly to the naked eye.

If grenades are still necessary to support infantry, then armor-piercing shells are just a kind of "existence ammunition" in the eyes of the troops. They must be available, but if you ask me how much they like them, that's really not the case.

As for the cult thing called armor-piercing shells, the comrades in the army completely rejected it after trying it on composite armor. They believed that this thing was useless against composite armor.

In fact, later on, except for John Bull who still insisted on retaining armor-piercing shells for attacking fortifications, the whole world no longer used this thing. By the way, this thing was invented by John Bull, and this is probably the biggest reason why they insisted on using it - the ancestral method cannot be changed!

"…The new tank uses a 593 armored steel base armor and a composite armor protective structure, with excellent protection performance of 450mm anti-penetration and 600mm anti-breakage…"

This protective performance just exceeds that of T-64 by one level. This is also the result of General Guan and his team trying their best to improve it with the help of Gao Zhendong. The fact that they can achieve this effect at 41.5 tons is inseparable from the successful weight reduction of artillery, engine and other parts. General Guan and his team have more weight to use for armor.

The T-64 has an armor penetration rating of 400 and an armor penetration rating of 450. As for the reason why the second-generation tanks have such high armor penetration ratings, it is actually very simple - you can't let yourself be penetrated, right? Your own guns have an armor penetration rating of 440 and an armor penetration rating of 600, so it can't be lower than this!

Not to mention that if it was lower, there would be 61 Fire watching closely, which would be very stressful! What? 61 Fire is yours? And there is no exit? That's fine.

Lao Guan and Lao He, the old enemies, were trying their best to catch up with each other, but in the end, Lao He was defeated - the caliber, length and volume of the cannon were all limited, and in this regard, Lao Guan was slightly more comfortable than him.

"I want the whole big one, the whole big one..." Lao He happened to be sitting behind Gao Zhendong. He was muttering to himself with gritted teeth and the sound of grinding teeth could be heard, which made Gao Zhendong laugh.

"…The new generation of tanks is equipped with an automatic fire extinguishing and explosion suppression system equipped with a red and ultraviolet dual-color sensor. The system action time is no more than 5ms, the fire extinguishing agent injection completion time is no more than 90ms, and the fire extinguishing agent has no obvious subsequent harm to the crew…"

Not only other comrades, but even the comrades in the army found General Luo's words new. They had not paid attention to this matter during the last acceptance inspection because they were too excited about the bullets and armor.

The significance of 90ms fire extinguishing is self-evident. Although it is impossible to suppress all secondary explosions, it can at least greatly reduce the probability.

The acceptance experts from all over the world were even more excited to hear this than the previous armor-piercing confrontation. After all, those things were too far away from the work of other comrades.

"We actually have this kind of technology? Isn't it too fast?" Some comrades found it hard to believe.

"90ms? Can we install a set in our laboratory or archive room so that we don't have to worry about fire?" Some comrades thought about their own work.

What's more, his idea was actually put into practical use in important places such as computer rooms, archives, and libraries. The automatic fire extinguishing system equipped with heptafluoropropane was widely used.

"…At the same time, the new generation of tanks fully considers the comfort of the crew members and the needs of continuous combat in harsh environments. They are equipped with auxiliary systems such as air-conditioning vests and collective three-defense systems, which greatly enhance the continuous combat capability of the equipment…" Mr. Luo reported even these small things in detail.

Gao Zhendong was working hard, and other comrades were not idle either. Finally, they came up with the collective three-defense system. This was much better than the second-generation tanks he knew in his previous life. The three-defense system relied on gas masks.

"...tanks are equipped with thermal smoke generators, smoke grenade launchers and other auxiliary equipment, which can provide effective cover for themselves and accompanying infantry in a variety of ways during the assault..."

Gao Zhendong almost wanted to shout, what the hell is this second-generation tank? If this thing is put outside, it will definitely be a third-generation tank!
