When it comes to tanks and artillery, everyone has different opinions, and the party faction represented by Chen Haisheng and the large-caliber long-body tube faction headed by Jiang Tao have their own opinions, and they are arguing fiercely. Pen % fun % Pavilion www.biquge.info

"I said Jiang Tao, the caliber of your tank gun is almost enough, our purpose is to cover the infantry attack, as long as we can destroy those fortifications and kill and injure those infantry, what's the use of you making such a long body tube and such a large caliber, it's hard to process, not to mention, the cannonballs with a large caliber are still few, and it's useless to make them, is it possible that you still have to rob those artillery who are attacking fortifications, I think the caliber of their anti-tank guns in France and Maozi is not large."

"Okay, Director Chen, even if what you say makes sense, I don't have to make too big a caliber, but this long-standing tube must listen to me." Jiang Tao thought about what Director Chen said is also somewhat reasonable, the caliber of this shell is indeed more difficult to carry, after all, the space of the tank is so large, and it is indeed difficult to bring a large caliber of the shell, but the long body tube is necessary, only the long body tube can ensure that the shell has enough initial velocity to pierce the target, so Jiang Tao plans to find a small-caliber anti-tank gun as a model, and put its gun body on the tank with a slight change, Jiang Tao's original target was the German Pak3637 mm anti-tank gun, But an unconscious remark on the side changed his mind.

"I said, Jiang Tao, Director Chen, what do you have to quarrel about, you can produce a small amount first, maybe Little Japan will not build tanks because they don't come in handy this time?" This sentence reminded Jiang Tao that the limit of the German PAK3637 mm anti-tank gun is to hit light tanks. If you encounter a series of opponents with thick armor such as Matilda tanks and B1 tanks, it will not be easy to use, not to mention that in the future, you will face the Soviet Union's modernized tank T34 and the heavier KV-1, which is estimated to become a knocking weapon". Jiang Tao set his sights on the German KWK39 60 times caliber 50 mm gun, which under normal circumstances, it is only possible to destroy the Soviet-made T34 tank within 100-200 meters, and it is still helpless against the KV tank. But given the current situation, this gun is already a good choice. "Wenda, how about we choose a 6060 caliber 50 mm gun as a tank gun, do you think our equipment is difficult to produce?"

Wenda touched the stubble on his chin and said, "Production can be produced, but I estimate that the weight of this thing is not light, your tank can not run fast when it is loaded, you have to think about it yourself, such a large diameter, if I want me to say that you can simply use a 46 times diameter is enough, the caliber is 45 mm, which does not drag down the speed, and the firepower and armor piercing are also taken into account. ”

"That's okay, Jiang Tao looked at the information of the system in his mind, there is a gun whose parameters are very similar to Wenda's suggestion, that is, the Soviet Union's M193745 mm anti-tank gun, this gun has been used by Lao Maozi until 1941, although it can't penetrate the frontal armor of the German No. 3 and No. 4, but there is no problem with penetrating the side armor, that is him, Jiang Tao exchanged the structural drawings of this artillery, and with the help of the system, the gun body was partially separated. As for the machine guns used to suppress the infantry, Jiang Tao felt that it was enough to directly use the ready-made 7.7mm light machine guns of the Northeast Army.

The firepower and maneuver in the Trinity have been done, and the last step is defense, to be honest, Jiang Tao has the most headache for defense, because for tank armor, it is still materials that play a decisive role, and his own system really can't help much. The only thing he can count on in his team is Wenda.

"Wenda, how about the armor we want to produce?"

"It's not bad, with the smelting equipment you gave, the quality of the steel is much better, whether it is toughness or hardness, I estimate that it is at the international level, but this output is really a little small, can you get some smelting equipment." Wenda really thinks that the smelting equipment that Jiang Tao got is really good, the only drawback is that the output is too low, only in the key parts of some weapons, such as aircraft engines, artillery barrels are willing to use these good steels, as for the steel used in the barrel and gun shield, it is even worse.

"I said, Jiang Tao, you don't plan to use all good steel to make armor, I can tell you, even if you use all good steel, it may not be able to play much of a protective role, I think the surface of this tank steel should have high hardness and wear resistance, and the inside should be toughness and shaping, which is not something that ordinary steel can achieve, my suggestion is that we just use general low-carbon steel, just use it in addition to a carburizing process of case hardening, and you should save some good steel."

"Then you can process a batch and take a look first, let's compare and compare." Jiang Tao also actually looked at the hardening technology that Wenda said was so magical.

Early the next morning, Jiang Tao was taken to the shooting range by the Wen army, a 37 mm battle defense gun was already waiting, the first experiment was made of armor made of steel with excellent performance, first 10 mm thick, in front of the battle defense gun was undoubtedly pierced, the next 15 mm, this time the battle defense gun only hit the armor a little dented, but did not penetrate it, and then fired a few more shots before the armor was penetrated.

Replaced with hardened armor, the first one was millimeters, but under the blow of the anti-aircraft guns, not even dents appeared. "It seems that this hardening process is really good." Looking at this result, Jiang Tao gave a thumbs up to the Wen army, but something unexpected happened, under the continuous firing of the battle defense artillery, the armor was not shot through, but a large area of cracking occurred, and the surface of the armor was full of cracks. Venda hurriedly signaled to stop the shelling and ran over to check on himself.

Jiang Tao also followed. "Looks like I'm still thinking highly of myself." Wenda looked at the armor and smiled bitterly.

"What's wrong?" Jiang Tao didn't understand that even if it cracked, the performance of this armor was much better than that without hardening.

"Hey, the toughness of the hardened armor has dropped too much, if the toughness of this armor is good, there should be no cracks." Wenda pointed to the rift and explained to Jiang Tao.

"Hey, but this one is much better than not hardening." Jiang Tao comforted Wenda.

"This is the big problem, this armor is too heavy after hardening, 10 mm armor is heavier than 18 mm unhardened, it is better to use 18 mm armor directly."

Jiang Tao looked at the erected armor, and paid attention to it, "I said Wenda, we can make the armor a little tilted, so that the thickness will not increase, as for the question you said, we can use ordinary steel to make the outer armor, and then add a thin layer of hardened armor after a little separation, when the shell hits the front armor, a powerful metal jet is formed, and the air layer can make the jet stretch and thin, and it will be boring when it rushes to the armor plate behind. In this way, the hardened armor will not be subjected to too strong impacts, and the problem of toughness can be avoided to the greatest extent. “

"There's some truth to what you're saying, let's try it."
