Chapter 261 Hand shaking (second update)

Because of the low muzzle velocity of rockets, the shooting distance is limited, basically from 50 meters to 400 meters. Some warheads are different, and the shooting distance is also somewhat different.

For moving targets, it is generally 200 meters.

After the test on infantry, it was aimed at armored vehicles. This kind of warhead actually has a hollow structure at the front, and uses the power of the explosion behind to form a metal jet to penetrate the armor.

There are two models in total. In fact, the difference is the caliber, that is, the difference in bullet diameter. The one for general armored vehicles is smaller, and the bullet diameter for tanks is larger.

The steel plate used in this test is of course an ordinary steel plate. The motorcycle factory does not have armor steel plates for armored vehicles.

Although last time I made a bulletproof vehicle for Big Brother in the north, Big Brother provided me with information on bulletproof steel plates, but it was not produced by the motorcycle factory.

In fact, the steel plates from the motorcycle factory can be considered homogeneous steel plates. They are all rolled, but they just cannot meet the standards of armor.

The first target was still 200 meters. Liu Hai pulled the rope and watched the rocket fly into the distance.

After the explosion, everyone stood up and walked towards the target.

When I came to the target, I saw a burning bullet hole left on the tilted steel plate.

When the inspectors finished testing the depth of the bullet holes, the expressions of the leaders present changed.

Then the steel plates were lifted layer by layer to determine the depth of penetration. Everyone saw Liu Hai's expression changing even more.

"The names of everyone present must be recorded and must be kept confidential." The troop leader looked at the data and directly issued the order.

The second test used the same type of ammunition, but the distance was extended to 350 meters.

This time I almost lost my grip because there was a gust of wind during launch.

Fortunately, the target shooting place is behind a hill. Rockets are greatly affected by external forces. Generally speaking, the armored targets should be placed as close as possible.

The breakdown results still haven’t changed much.

When the third type of tank armor-piercing bullet was taken out, it was obviously larger than the previous one.

Liu Hai pulled the rope to launch several leaders holding binoculars in their hands and watching carefully.

When the armor-piercing bullet hit the steel plate and a burst of smoke erupted, the leader of the First Machine Department was a little confused: "It seems to have penetrated?"

"I also saw that it seemed to have penetrated, and a line of smoke was emitted from behind the steel plate?" The troop leader also nodded.

The group of people almost trotted to the back of the target and gasped when they saw a hole appearing behind the steel plate.

So many layers of steel plates were actually penetrated?
What is this concept?
Liu Hai didn't say anything. You will be more surprised by the last one in a while. Liu Hai is also wondering whether to take out the multi-layer armor and learn from Big Brother, just mix two layers of aluminum alloy inside.

However, considering the horsepower of current domestic tanks, let’s forget it and wait until some time... Forget it, just wait until I get a 59 modification later...

Because it is troublesome to change, for example, the bangs now need to be changed to armor, so the weight will increase.

If the engine is changed, the power cabin size will not be enough. Should we follow the example of Gallic chicken and weld and add 4 meters to the front of the aircraft carrier?
Then I found that the interior was not suitable, so I simply made a 59 modification, and arranged for explosive reactive armor and so on... all together.

So Sun Aiguo hurried back and pulled some steel plates from the factory.

When the final king of tandem armor-piercing bullets came on stage, the steel plates were not enough again.

The tandem armor-piercing projectile can theoretically penetrate 200 mm of homogeneous armor behind explosive reactive armor within 600 meters.

There is no explosive reactive armor there. Let's put it this way. Just take out one of Big Brother's tanks. As long as it hits, it will be nothing.

Of course, this is also the weakness of RPG, the effective shooting distance, but at least there are countermeasures, right?
Faced with the steel plates brought by these motorcycle factories, it was even more difficult, so I added steel plates and continued testing...well, the same result.

The leaders present looked at Liu Hai with a different look on his face, and everyone issued a confidentiality order again.

Liu Hai's laboratory is all sealed up.

The leader of the unit and the leader of the First Machinery Department reported the matter to the superior leader.

The superior leaders looked at these data and couldn't believe it. After all, the data was too strong. The superior leaders were very concerned about this aspect.

"Is this thing real?" the superior leader asked with a doubtful tone.

"Leader, you still don't know who we are?" the leader of the army and the leader of the First Machinery Department said quickly.

"Is this Comrade Liu so powerful?" The superior leader looked at this data and his hands started to shake.

Although the effective range of this rocket launcher is shorter, facing a tank is much better than charging up with grenades tied before.

"Leader, you have forgotten that Comrade Liu Hai actually started with the large-scale heartless cannon." The leader of the First Machinery Department reminded at this time.

Only then did the superior leader recall that Comrade Xiao Liu had acted without conscience, which surprised him.

"It seems that I got it right. This thing needs to be mass-produced, equipped with a large number of troops, and kept confidential. In addition, you can test it with tanks. Without experimental data, it will be unconvincing. Don't be afraid of spending money." The superior leader looked at it. Looking at this data, I felt a little unconvinced, so I spoke.

"Next step we will conduct a test." The leader of the army nodded, just use a few tanks for testing, or at worst, just use a tank shell.

"Report it to me when the results come out again, and give Comrade Liu Hai a good reward." The superior leader looked at the data in his hand and felt confident that he could penetrate such a thick steel plate.

"Comrade Xiao Liu is very knowledgeable about military equipment, so let him work on it." After hearing this, the superior leader said again.

"A while ago, Comrade Xiao Liu applied to visit the factory that manufactures gun barrels, but we haven't approved it yet." When the leader of the First Machinery Department heard this, he said.

"This is unnecessary. Comrade Xiao Liu, I believe him. Let him go and see. Maybe he has some new ideas."

"As soon as there is any progress in this matter, report it to me immediately to see how Comrade Xiao Liu did it." The superior leader was very happy. There was good news in Northwest China, but he couldn't easily bring it out. It’s the same, you can take it out to open Big Brother’s eyes when necessary, right?
"Leader, Comrade Xiao Liu, you don't know? You can even export roast chicken equipment." The leader of the First Machinery Department chuckled. "That's true!" The superiors laughed when they heard this. After all, it was unexpected that the roast chicken equipment could be exported, and 100 sets were exported.

"Comrade Xiao Liu has a lot of ideas. When he built that super heartless cannon, I felt that this little comrade's ideas were beyond the imagination of ordinary people." The leader of the First Machinery Department continued. He really didn't expect it at the beginning. After all, he had no conscience. How many years ago was that?

"Yes." The superior leader nodded.

All the data and drawings in Liu Hai's laboratory were taken away, involving RPG.

Then the data and drawings were copied and handed over to military industry experts for study.

The reason why Liu Hai is not allowed to have contact with these experts is actually to keep it confidential.

Liu Hai's data manuscripts and so on were sealed as top secret information.

Moreover, the leaders of the First Machinery Department also discussed with the leaders of the troops, and it was not necessarily a good thing to let Comrade Liu Hai freely express himself and contact other military industry experts.

The army's military industry experts looked at the design drawings and these data, and their jaws dropped in surprise.

"Leader, are these materials the most advanced abroad?" Military industry experts looked at these materials and asked the leader in surprise.

"Why do you say that?" The troop leader asked curiously when he heard this.

"The design concept here is too advanced. This piezoelectric instant fuze has simply subverted our imagination." The military industry expert said.

"What's so special about this fuse?" the troop leader also asked curiously.

"There is a period of time for a traditional mechanical fuse from triggering to detonating, and during this time, the rocket can fly ten centimeters. That is to say, between the triggering of the rocket and the detonation of the rocket, it has already contacted the opponent's vehicle body, and these ten centimeters It will cause the rocket to deflect, thereby reducing the attack effect."

"And this piezoelectric instant fuze can detonate all the explosives in the bomb instantly, allowing all the explosives to explode in an instant and exert their full power." The military industry expert continued.

"And this tandem ammunition..."

Of course, these military industry experts don't know that tandem munitions are for explosive reactive armor. That stuff hasn't come out yet. It won't come out until 69 at the earliest, and Big Brother didn't equip it until the 80s.

Because of a certain war in the 80s, old-fashioned tanks were equipped with explosive reactive armor to withstand RPG and anti-tank missile attacks. Big Brother paid attention to it and then designed its own explosive reactive armor.

Of course I won't take out the bangs. If I take them out now, I won't show it to Big Brother. Anyway, we don't have many tanks of our own and the other side has many. There is no need to increase the strength of the other side's tanks.

Liu Hai received good news, that is, he can go to Benxi Iron and Steel Co., Ltd. to visit the production of gun barrels.

The army's military industry experts are working overtime to produce according to the drawings and data. The RPG involves a lot of new materials, from explosives to fuzes, and then to the alloy material of the launch tube.

When Liu Hai went to Benxi Iron and Steel Co., Ltd. to visit the production of gun barrels, he received an order from his superiors at Factory 298 in the southwest to manufacture a batch of triple sights and allocate funds and equipment to upgrade the factory.

Factory 298 has a very long history, which can be traced back to 30 to [-] years ago. All kinds of optical instruments seized on the peninsula were delivered. There are air rangefinders here, as well as sights equipped by Aramco. Telescopes, etc.

The manufacturing of triple mirrors is a troublesome thing for Liu Hai, but it is not very troublesome for Factory 298, because they specialize in this.

As early as 56, Factory 298 obtained infrared sights for guns seized from Aramco.

Moreover, the task of this triple mirror is very huge, requiring at least [-] to be manufactured in one year, and some equipment and instruments that need to be imported are beginning to be put in place.

This may be the influence of the bangs design of the short assault rifle.

After receiving the triple sight mission, I received another mechanical sight. This is actually the mechanical sight on the rocket launcher.

Factory 298 has ushered in a huge development, and the resources of superiors have been continuously tilted.

"How about a visit there?" Sun Aiguo asked after Liu Hai came back from the visit and reported to Sun Aiguo.

"After reading it, I have some ideas, but I need to think about it more." Liu Hai went to see it just to find an excuse.

"As long as you have ideas, that's good. If you have ideas, that's good." Sun Aiguo nodded and said.

"Optical sighting equipment, if you have any ideas, just give me the drawings and I will submit them for you. It takes too much time to build the optical sighting equipment by yourself." Sun Aiguo heard Liu Hai complain about making it himself last time. The scope was too long.

"That's just right. I want to design a sniper rifle here, but I just lack a scope." Liu Hai breathed a sigh of relief. It is very difficult to create a high-power sniper rifle scope. The key is that he is not very familiar with this field.

"Then give me the drawings and I'll send them to the ministry as soon as possible. What caliber are you planning to design for your sniper rifle?" Sun Aiguo asked curiously.

"Maybe 12.7mm." Liu Hai designed an anti-materiel rifle. Who said this thing can't hit people?It’s still accurate to hit them one by one.

Sun Aiguo spit out a mouthful of tea with a puff, and asked, "Are you sure this is a sniper rifle?"

"Leader, don't forget that we have it in the exhibition room over there. I think the sniper rifle needs to be of a larger caliber. It can be used to hit people or armored units." Liu Hai looked at Sun Aiguo and said.

Sun Aiguo wanted to say that that piece of shit was useless. It was heavy, long, and took up time. It was fine for hitting people, but it was useless for hitting other people. It was useless.

But when he thought that the person in front of him was Liu Hai, Sun Aiguo didn't speak. Maybe Comrade Liu had his own ideas.

"Okay then, give me the design drawing of the scope as soon as possible. If there is something you are not good at in the future, just give me the design drawing first and I will submit it to you. We will make everything ourselves, and we will do it in the future. You should stay away from explosives and other things, they are very dangerous after all." Sun Aiguo reminded him thoughtfully.

Sun Aiguo took a closer look at what happened this time, but he was still scared.This thing only penetrates the steel plate so deeply. If something unexpected happened during the test, I don't dare to think about it.

"Thank you for your concern, leader." Liu Hai smiled.

"This time you will raise your technical level to a level six engineer."

"Thank you leader."

"Comrade you are nothing like the others." Sun Aiguo was very emotional when he saw Liu Hai like this.
