Although the train cannon is very powerful, it is extremely bulky, and the preparation time for firing is extremely long, sometimes it takes an hour to prepare for launching a cannonball, and Lin Fei has always scoffed at this kind of weapon.

Since Lin Fei was disdainful of train artillery, why did the Huaxia Army still have train cannons?

This has to start with the Russians.

It turned out that when the Russian army was preparing for war, it deeply felt that its own firepower was insufficient, and the hydraulic brake and retreat machine that had been widely used in the artillery of the Chinese Empire, and the imitation model of the Russian army was not yet mature, so the rate of fire of the Russian artillery was very slow, and the rate of fire was slow, and the firepower projection ability was poor.

The Russian army urgently needs some weapons to strengthen its firepower, and the high-level thought of the train cannon, so the Russian army's high-level organized experts and technicians to develop the train cannon, and finally came up with one.

This train cannon was originally intended to be used when the Chinese Empire recovered Hailan Bubble, but unexpectedly, before the cannon could be fired, the cannon body was fatally damaged - the bolt seal was broken.

Once the bolt seal is broken, the gunpowder gas will gush out of the barrel when the shell is fired, and the caliber of the train gun is as high as 600 mm, and the weight of the shell is extremely large, so there is a lot of propellant, and the gunpowder gas is naturally more.

What's even more dangerous is that after the gunpowder gas is sprayed, the range of the shells will change dramatically, and no one can know where the shells will fly.

Russian technicians raced against time to repair the train guns, but until the end of the war, the train guns were not repaired normally, and the train guns carefully prepared by the Russian army did not fire a single shell.

Later, the Huaxia Empire recovered Hailan Pao and left all the technicians behind, only then did they discover this train gun, how to deal with it, Niu Dalong asked Lin Fei for instructions, Lin Fei heard that the caliber of the train gun was as high as 600 mm, and there were related technicians, he was very happy, so he thought about getting these technicians to Huaxia to develop a new generation of large-caliber naval guns.

But later, Lin Fei asked in detail, and then he learned that the artillery developed by these technicians was completely used to increase the thickness of the cannon body to improve the strength of the barrel, and such a gun could not be used on the battleship at all, because the weight was too great for the battleship to bear.

So Lin Fei gave up the plan to develop large-caliber naval guns, and put all the shipbuilding resources on the development of aircraft carriers, Lin Fei also comforted himself, since he already knew that battleships were things that would be eliminated, so don't bother to develop them.

Speaking of aircraft carriers and aircraft, Ling Xue's computer will become the strongest booster for developing them, because when designing aircraft carriers and aircraft, a large amount of data is required to calculate, and with computers, the calculation speed will undoubtedly increase significantly.

Ling Xue has been developing computers for three years, but she still can't get results, and Lin Fei has "punished" her many times for this......

Lin Fei dispelled the idea of getting the technicians to Huaxia, so they let them stay in Hailanpao and continue to repair the train cannons, when fighting Mongolia, due to the low level of knowledge of the Mongolian military and civilians, a huge train cannon was enough to scare them to death, so Lin Fei wanted to use the railway to transport the train cannons to the front line, and deter the Mongolian army.

Since the train cannon is meant to be used as a deterrent, there is nothing to keep secret, so Niu Dalong is relieved to bring Prince Bakhtum to visit.

Prince Bakhtum was so frightened that he broke out in a cold sweat when he saw such a huge cannon, although he had seen artillery, but those were old guns with breech charges, which could only fire solid projectiles or iron sand, and the power was obviously very different from this 600 mm caliber train gun.

Niu Dalong was very happy to see that Prince Bakhtum was frightened into a cowardly look, laughed heartily, and said to Luo Wei: "Can we test this cannon?" ”

Luo Wei smiled and said: "Commander, it's really time for you to come, that's right, our train cannon is about to be tested, what, let this Mongolian prince take a look?" ”

"Of course, people come all the way from Mongolia, and they can't let them return empty-handed, by the way, come here, go and bring all the Mongolian cavalry prisoners captured in the last battle." In the last battle, fifty-two Mongol prisoners of war were captured, all of whom were imprisoned in the prisoner of war camp in Hailanpao, and they were summoned and shocked.

Luo Wei ordered the Russian technicians to start the train cannon and go to the test site, no one in the Chinese soldiers would fiddle with this train gun, so the operation was done by the Russian technicians, and Luo Wei was not worried that these Russian technicians would turn the muzzle of the cannon to shoot revenge on the Chinese Empire, because it would take more than ten minutes for the train cannon to turn the muzzle, which was enough time for the Chinese soldiers to shoot the Russian technicians.

The Russian technician entered the locomotive and started, and the locomotive pulled a huge train cannon weighing more than 200 tons out of the warehouse and rushed to the test site.

After two hours, the train artillery arrived at the test site, which was a large wasteland, with rows of targets erected more than ten kilometers away, and at this time the Mongolian prisoners of war also arrived, and Luo Wei arranged them behind the bunker 600 meters away.

After more than an hour of loading preparations, the train cannon was finally ready to fire, Luo Wei took Niu Dalong and Prince Bakhtum and others to the bunker four hundred meters away, and the launcher also followed, because the charge of this type of train cannon was too large, so the sound was very loud when firing, and people would be injured if they were too close, so the launcher had to fire the cannon remotely in the bunker four hundred meters away.

The launcher sent out a signal of "about to open the cannon", Luo Wei took out three ear bags, brought one with himself, and handed the other two to Niu Dalong and Prince Bakhtum, Niu Dalong obediently put the ear bag on his ear, but he didn't expect Prince Bakhtum to twist his head and said proudly: "This king is a hero, why not be afraid of firing cannons." ”

Niu Dalong directly buckled the ear bag on Prince Bakhtum's head, and scolded: "Hero fart, obediently put it on Lao Tzu, if you are deaf, Lao Tzu will have to treat your injuries." ”

Prince Bakhtum could only obediently put on his ear bag, and when everything was ready, the launcher pressed the launch button, only to see the train cannon in the distance tremble violently, and a huge smoke surrounded the cannon body, and the cannon body retreated five meters along the rails under the action of recoil, and a behemoth of more than two hundred tons retreated five meters under the impetus of recoil, and the power of this launch can be imagined.

Prince Bakhtum felt the ground shake under his feet, and despite wearing ear bags, he felt deafened.

At this time, I only heard a terrible whistling sound flying out into the distance, and with the sound, more than a minute later, I saw a huge column of smoke in the far distance, and then a thunderous sound came from a distance, that is, the explosion of a cannonball.

Soon the smoke and dust dissipated, the sound stopped, and the test site returned to calm, Niu Dalong took off his ear bag and said to Prince Bakhtum: "Let's go, let's go and have a look." ”

After Niu Dalong finished speaking, Prince Bakhtum did not react, it turned out that the explosion scene just now was too shocking, Prince Bakhtum was already stunned, forgot to take off the ear bag, and looked at the explosion point in the distance in a daze.

Niu Dalong laughed, raised his hand and took off Prince Bakhtum's ear bag, and said: "Let's go, let's go to see the bombing point, come here, and call those Mongolian prisoners of war together." ”

Niu Dalong led Prince Bakhtum and everyone to ride forward, and ran for half an hour, and before he could stop, Prince Bakhtum asked in a trembling voice: "You guys...... Your cannons ...... You can hit that far......"

Niu Dalong ignored him, it turned out that the shell hit a place twenty-five kilometers away, twenty-five kilometers, and he had to run on a horse for a while, and then ran for a while, and Prince Bakhtum saw a huge pit appear in front of him, the diameter of the pit was almost 100 meters, and the snow of more than 200 meters around the pit was gone, and the earthy yellow ground was exposed.

Niu Dalong pointed to the big pit and smiled: "Look, that's the explosion point." As he spoke, he came to the edge of the pit, Niu Dalong turned over and dismounted, and Prince Bakhtum followed closely and came to the edge of the pit, only to see that it was full of water, and a thin layer of ice had formed on the water.

Niu Dalong turned around and beckoned Luo Wei: "Measure how deep this pit is, the groundwater has been blown out, and you can't see the depth." ”

Luo Wei took out the probe rod with a few technicians and stretched it into the water, and the probe pierced the thin ice, all the way down, and it stretched in for three or four meters before stopping.

The technician measured it and reported: "The depth of this crater is about five meters. "It turns out that the shells used by the Russian train artillery are filled with black powder, and in terms of explosives technology, Russia is not as good as Japan, Japan has used picric acid, and Russia is still using black powder.

After the Russian technicians defected to the Chinese Empire, they filled the Chinese Empire's trinitrotoluene explosives, and the explosive power of trinitrotoluene was much stronger than that of black powder, so it exploded such a terrifying crater in the ground.

Niu Dalong laughed, turned back to Prince Bakhtum and sneered: "I said Prince, look at such a bombing pit, how many Mongolian cavalry have to be thrown into it to fill it." ”

Prince Bakhtum has been stunned by the huge power of the train cannon, and now when he heard Niu Dalong say this, he was suddenly frightened into a cold sweat, his legs were weak, and he knelt in front of Niu Dalong with a plop, crying and saying: "I surrender, I surrender, my grain, livestock, and women are all the Flying Emperor's, and I have been conquered by the Flying Emperor." ”

Niu Dalong stretched out his hand and touched Prince Bakhtum's head with satisfaction, "Really good, get up." (Canghai shared the writing story on the WeChat public platform, please search on WeChat - qietingcanghai, that is, listen to Canghai's pinyin, reply 2 to watch)
