"Yes! We have obviously controlled the accuracy of the shelling of a single rocket to about 30 meters, and even when the four tubes were launched at the same time, the accuracy did not change so much. Is it due to the interaction of the air currents generated by the launch? Qian Wei on the side scratched his head suspiciously, "muttering to himself".

Liu Lang smiled slightly, otherwise these future elites are all high-IQ talents, and they play so naturally for their future wives.

The shelling scene in the high-powered telescope is already very clear, and the impact point of the rocket deviation should be roughly estimated to be about 100 meters, which is actually very awesome. You must know that the accuracy of the 63-type 107 rocket in the future Republic of Black Army Industry 63 can only be controlled within the accuracy range of 50-100 meters, and if you want to increase the accuracy, you must reduce the range to 5000 meters.

Even if it is the current accuracy with an error of about 100 meters, Liu Lang knows very well in his heart that the future elites such as Su Xiaomei and Qian Wei have bloomed their unparalleled wisdom, and they are worthy of being the fathers of the two bombs and one star in the future.

What's more, rockets never rely on precision to win, they rely on the concentration of fire, as much as possible, a salvo of more than a dozen rocket artillery, is the wild dance of hundreds of rockets, covering an area of tens of thousands or even tens of thousands of square meters, the shell fragments and air waves produced by the violent explosion are enough to sweep everything in the shelling area, and the error of a mere 100 meters is hardly a disadvantage compared with its huge power.

"It's already great, with this range and this accuracy, it's already up to our needs." Liu Lang shook his head and comforted Su Xiaomei, who was obviously a little annoyed beside him, and said, seeing that the little girl was still a little stupid, Liu Lang couldn't help but smile and pointed to Zhao Ergou, who was holding the telescope and reluctant to put down a big mouth and drooling, and said: "If you don't believe it, you can ask Battalion Commander Zhao what he thinks of the effect of the rocket artillery test." ”

"My good girl, Professor Ye, I am convinced, the teacher teaches well, the students learn well, and the treasure of my artillery battalion in the future will be it." Zhao Ergou put down the binoculars, looked at Professor Ye with great sincerity, and said sincerely.

"Really? Battalion Commander Zhao, do you really think so? The chagrin on Su Xiaomei's face finally dissipated a little.

"Of course, a salvo of this cannon developed by expert Su is equivalent to nearly ten mountain guns in my artillery battalion firing at the same time, although the accuracy is not as high as that of mountain artillery, but as long as you shoot enough at a time, that little error is a ball, and the little devil will definitely be blown up to cry dad and mother." Zhao Ergou is much more respectful to the young and gentle Su Xiaomei now.

"Oh, look at my broken mouth, how can I say foul words in front of you, Expert Su." After the words of praise were spoken, the thing hurriedly gave himself a small mouth to show self-punishment, although it was estimated that it could not kill a mosquito.

"Poof, Camp Commander Zhao, don't call me an expert, it's awkward, it's better to call me Su Xiaomei in the future." Zhao Ergou's appearance directly amused Su Xiaomei.

"That's good, that's good, I'll call you a little sister expert in the future, and I'll have to build a few more guns for my artillery battalion." Zhao Ergou saw the power of rocket artillery at this time, what else is there there?

Looking at the two of these two who were fighting with each other just now, you and I complimented each other at this time, and everyone couldn't help but be happy. Of course, it wasn't just the two of them, but the test launch of the rocket launcher was a success.

Just like what Liu Tuanzuo just said, the shooting range was blown up in smoke just now, which has proved that as long as the rocket launcher fires a salvo, a small accuracy error is really nothing.

The future main artillery of the independent regiment can basically be completely finalized, and all that remains is to start full production.

However, the surprise of all the officers of the Independent Regiment present did not end.

In other words, Su Xiaomei's performance is not over yet.

"Hee-hee, Captain Liu, do you remember a story you told me about ancient rockets last year?" Su Xiaomei suddenly asked.

"Ancient rockets?" Liu Lang was slightly stunned, in the past two years, he has had a lot of things to fool the future elites, and he really has no impression of this.

That is, an ancient man in the Song Dynasty fantasized about flying his rocket to the moon. Through experiments, I found out that our Chinese ancestor was so wise that the method he used was actually possible, and if the rocket was big enough, I even thought his fantasy would succeed. Su Xiaomei continued.

"What do you mean?" Liu Lang showed a trace of irrepressible joy on his face.

"Yes, we succeeded, just half a month after your last inspection, our project team successfully developed." Su Xiaomei nodded solemnly.

Liu Lang was really stunned now.

As soon as Su Xiaomei reminded him just now, he finally remembered the story he had fooled Su Xiaomei about the rocket. However, he is just borrowing the name of the ancients, and what he is talking about is actually what the current group of people will do in the future.

The rocket that can fly to the moon is not designed by the ancients who whimsically used gunpowder as propellant, but naturally they are the rockets designed by future science and technology masters who can send satellites to the sky. Liu Lang actually only gave Su Xiaomei, Qian Wei, and Peng Wu a future goal, and didn't expect them to make it now. After all, in the future, the Republic mobilized the strength of the whole country, and it took them many years to send China's first satellite through the atmosphere into space.

Liu Lang also used the name of the ancients to briefly talk about the principle of the rocket graded thruster, when the rocket flies to a certain height, the first-stage thruster separates to reduce the weight, and then the second-stage thruster ignites and starts, and then the third-stage thruster, so that it can fly higher.

With this simple principle that future schoolchildren know, they are making it now? This is too magical, isn't it? Great gods, if you hang like this, the little devils will cry! Could it be that my brother can send a missile to hit Tokyo in Sichuan? Then let's fight with them and start building missiles now, and don't feel too good about long-range bombing.

"You made a rocket that can go to the sky?" Liu Lang swallowed his saliva with some difficulty and asked in disbelief.

"Head Liu, you think too highly of us! It's still in the sky, but if the rocket can fly out, it can be regarded as heaven! Su Xiaomei rolled her eyes.

Obviously, Liu Tuanzuo is thinking too much.

Su Xiaomei always said rockets, not rockets.

After all, it took her and her classmates more than two years to shoot a rocket for several kilometers, and the kind of future missile that a certain fat person thought of could hit hundreds or even thousands of kilometers was a pipe dream.

The first-generation missile "V1 rocket" that the elite scientists of the Third Reich are working on has only appeared for the first time in nearly a decade! It was already one of the pinnacle technologies catalyzed by World War II.

Compared with them, not only is it still early for these still immature elites, but even all kinds of materials cannot be provided by the whole of China, and Liu Tuanzuo can't buy them with money.

Although the dream of missiles was shattered in an instant, another black technology that Su Xiaomei came up with made Liu Lang still ecstatic.

Su Xiaomei applied the principle of graded rockets to rockets, a box of special rockets, each weighing 24 kilograms, and the extra six kilograms were all fuel.

After several officers led by Major Zhao Ergou dragged the rocket artillery and ran for several kilometers almost to the base of the independent regiment for test firing, the range of the extended-range rocket was measured to be as high as more than 13 kilometers, which was more than 60 percent higher than that of the ordinary rocket with a range of 8 kilometers.

This completely means that the range of the Storm rocket launcher with extended-range rockets is completely crushed at the limit range of 12,000 meters of the main Japanese 150 heavy howitzers.

How important is the range of the main artillery? It's more important than you think.

In the past time and space, before the Japanese army launched a full-scale war, it increased the range of its main 150 heavy howitzers to 12,000 meters, and after the government detected this information, it put forward the range requirements for the batch of 150 heavy guns that it was about to import to the Third Reich, requiring it to reach a range of 15,000 meters.

In order to meet the needs of the Chinese military, the weapons designers of the Third Reich directly changed the original 30 times the diameter of the 150 howitzer to 32 times the diameter, which is to put it in layman's terms, that is, the barrel was lengthened.

The Japanese, who had already finalized their artillery and equipped their troops, could only scold "Baga" when they were pressed and beaten by Chinese heavy artillery with a range higher than themselves on the battlefield, and the only thing that made them happy was that there were too few such heavy artillery in the national army, and they still had planes to help, otherwise, they would really be beaten and cried.

But now, the "Storm" rocket launcher of the independent regiment with extended-range rockets can definitely become the existence of the "Baga" of the Japanese heavy artillery brigade again.

If it weren't for the existence of Qian Wei, Liu Lang might really open his arms and play a "hooligan" and hug this "Chinese Marie Curie" who has a brilliant future.
