Chapter 685: Starting at 50%?

Besides, this is just preliminary research, and it won’t cost much money.

A leader said: "If we follow the method of using the engine as traction, we can actually save a lot of money. At least it should be no problem to carry out preliminary research. Well, let's use 11500."

After saying that, he also made a move.

"You have one in ten thousand,

I have eleven thousand.

They are all one in ten thousand..."

OK, it's stuck. The chief turned around and looked at the leader of the Defense Work Committee: "Come on, connect it, connect it. I know you like this."

?! Commander, what do you mean?
Tolerable or unbearable!
"It's so far away!" The leader of the National Defense Work Committee came very quickly. It's better than what I wrote. I have to see the status, but compared to this? Who is afraid of who?

"Hahaha, great! Great response. If everyone has 11,000, then just look at each other and don't hit anyone. If you ask me, this last sentence is what saves your poem."

Everyone laughed together.

Gao Zhendong had just finished revising the tutorials for project managers and system analysts and sent them to the Institute of Computing when someone came to see him.

He had never seen the visitor, but he had heard of them, at least he had heard of their achievements.

130 fire.

These comrades are from Fenglei Machinery Factory. Just by hearing the name you know that their products are not to be trifled with.

The 130 fire was a type of equipment that Gao Zhendong felt quite regretful about in his previous life.

Compared with 107 fire, it is not much farther and not much more powerful, but there are quite a lot of them.

Some things, if they are not good enough, the more equipment you have, the more regrettable it is.

Please note that it is a pity, not that it cannot be equipped. The difference between the two is essential. After all, no matter how small a sparrow is, it is still meat, which is better than nothing.

No matter what the troops think, in Gao Zhendong's opinion, the troops are probably trying to get equipment with some pressure.

Coming with them were staff from the Defense Work Committee and comrades from the Land Equipment Bureau.

This is very unusual, what is this for?
If comrades from the Land Equipment Bureau also came, it would be normal, after all, technical exchanges are very important to them. However, if staff from the Defense Work Committee also came, and they are not ordinary staff, then the message conveyed by this incident is unusual.

After all, they are the organizers and managers of scientific research, but they are generally not responsible for specific technologies.

This time, it was the comrades from the Defense Working Committee who spoke first: "Comrade Gao Zhendong, in summary of your speeches at many meetings, we have also conducted some research and analysis, and we feel that in terms of rocket launchers, it is necessary for everyone to sit down and conduct a thorough analysis and study to see how this matter should be handled and whether the existing work direction needs to be adjusted."

Gao Zhendong was overjoyed when he heard this. Adjustment? That's right. He had long been dissatisfied with the 10mm round with a range of just over 130 kilometers.

This is not to say that we are unhappy with the researchers. The comrades who are working on this thing have also developed it based on the existing conditions. Who doesn't want better?
Comrades from the Land Equipment Bureau gave a brief account of the investigation.

"…The main point of discussion is still about the range…"

Although the 130 fire has not been completed, its technical and tactical indicators have been clarified.

Although the 130mm cannon doesn’t look very big and its barrel is short and thick, it is assigned to the divisional artillery regiment, which is very confusing.

In the eyes of military fans of later generations, since you are assigned to the divisional artillery regiment, and it is a rocket launcher, then your range should be the longest in the divisional artillery regiment.

In fact, this was not the case. In the divisional artillery regiment at that time, the cannon with the longest range was the 85mm cannon, followed by the 122mm howitzer. Unfortunately, the 130mm cannon was defeated by the 122mm howitzer by one kilometer.

The larger the caliber, the smaller the range, which is simply the opposite of what Tiangang means.

Of course, this is related to the structure of the gun. The biggest difference between a cannon and a howitzer is the length of the cannon barrel. So when the caliber of howitzers increased from 39 to 45 and finally to 52, we basically no longer heard of the cannon as a type of gun, and it was replaced by the howitzer.

But unlike these two, for a rocket launcher with the simplest gun structure and whose entire capability lies in the missile, the 130mm caliber has a range of just over 10 kilometers, which is very cool.

"Comrades thought that this gun was very powerful and had a high firepower density, but the 10-kilometer range in the design made it impossible for everyone to put many ideas into practice. One comrade joked that he had thought that this thing could make people pee three feet high in the wind, but he didn't expect that it would wet his shoes in the wind."

Gao Zhendong did not rush to draw conclusions, but asked a question: "What is the tactical mission of the 130 rocket launcher now?"

The comrade from the Land Armament Bureau flipped through his notebook: "Threaten the enemy's assault armored clusters, attack the enemy's shallow depth targets, block the breakthrough points, and make up for the firepower gap of the barreled artillery."

When Gao Zhendong heard this, he felt that this tactical mission sounded strange.

"Threat an assault armored cluster? Why must it be an assault? What about those in assembly, transfer, and other states?" Threatening an "armored cluster" and an "assault armored cluster" may seem similar, but there is a big difference between them.

"We can't reach them. With a range of only 10 kilometers, we can only threaten those in the assault. Even those in the assault can only threaten those who are close by."

Gao Zhendong understood that this was a task determined according to the shooting range, and it was a case of cutting one's feet to fit the shoes.

"Why is the target of the rapid attack shallow depth?"

"It's the same. We can't reach the great depth." The comrades from the Land Equipment Bureau complained. The comrades from the Defense Work Committee burst out laughing, making the comrades from the Fenglei Factory blush with laughter.

Gao Zhendong understood: "It seems that to make up for the lack of firepower of the barreled artillery, we also need to make up for it downwards?"

This is a nice way of saying it. A barreled artillery can achieve a short range by adjusting the angle and charge, and any needs can be compensated downwards.

"Well, yes, at least this thing has a very high firepower density, which is still very good. By the way, we originally wanted to add a new tactical mission, counter-enemy artillery, but after seeing the range, it seems impossible. It's okay to fight against noobs, but for opponents of the same level, the range of this thing is not enough. In addition, the range of the new 122 howitzer has been greatly increased, so this thing is not reliable for counter-artillery, so forget it."

Gao Zhendong knew this better than any of them. The maximum range of the new 122mm howitzer was 18 kilometers, and the 130mm howitzer could only hit small and medium-caliber mortars with a range of 10 kilometers.

The comrades at the Fenglei Factory couldn't stand it any longer: "This 10-kilometer target has been set for a long time, and we dare not change it casually. Besides, rockets are meaningless if they can't hit the target accurately if they are fired far away."

This is the biggest reason why current rockets can’t reach far, they are inaccurate.

Of course, there are other reasons, and none of them can escape our grasp.

Gao Zhendong smiled and tried to smooth things over: "We are preparing to change the indicators. Don't worry, we can discuss it slowly."

The comrades at Fenglei Factory felt very comfortable hearing this.

Gao Zhendong looked at the comrades from the Land Equipment Bureau and asked: "After your research, what do you think is the appropriate range for this gun?"

A comrade from the Land Equipment Bureau said: "We also held an internal meeting and discussed it. We feel that under the current environment, at least 20 kilometers or even 25 kilometers is enough."

This will at least ensure that the new 122 howitzer that we are developing can be suppressed in terms of range.

There is no way around it. It's just like the comrades working on tanks and anti-tank weapons. Now they can't find suitable opponent equipment to use as a reference, so they have to fight each other with their latest products. Some comrades even came up with the incredible operation of using the self-forged fragmentation warhead of the terminal-sensitive projectile to attack the composite main armor and heavy explosive counter-attack.

The comrades in charge of artillery in the Army could not find any enemy division (brigade) howitzer with a range more suitable than the new 122 howitzer, so they had to compete with themselves.

Gao Zhendong carefully looked at the design data of the existing 130mm round and said with a smile: "For this range, it means that the ammunition must be greatly modified. For 15 kilometers, I have some confidence that there is no need to make major changes to the ammunition."

Comrades from several parties were shocked when they heard this. No, this is how you propose targets? Starting with 50%?

At least the comrades in the Land Equipment Bureau and the Defense Working Committee all knew that the new 122 howitzer had a range increased from 11.8 to about 18 kilometers.

As for the word "certain confidence", in their concept, for Gao Zhendong, it means the same as "strong confidence".

"Chief Engineer Gao, can the range really be increased to 15 kilometers without major changes to the missile body size?" The comrades from the Land Equipment Bureau's eyes were full of sparkle, they were really interested.

Gao Zhendong was a little surprised. Could it be that you are here to bargain for more than 20 kilometers? Are you asking for a high price and waiting for me to pay you back on the spot?
However, he was really confident about the 15 kilometers range. The 130 extended-range rocket he knew in his previous life did not have a major change in size, at least it did not break through the limitation of the directional tube, and the range was increased to 15 kilometers.

And he just looked at the design data of this missile. As for the rocket engine, how can I say it...

High emotional intelligence: there is still great potential.

Low EQ: The design and materials are average.

He mentally calculated the difference between existing propellants and the one he had, tried other configurations, and applied design formulas.

Then, he answered very confidently: "Yes, without major modifications to the missile body, it can reach more than 15 kilometers."

The comrades from the Land Equipment Bureau were overjoyed. What they said made Gao Zhendong understand what it meant to have both. "Great! I'll invite the comrades from 107 to come and learn from you. You can give us some guidance. We don't need to use 50%. Let's be conservative and raise it to 30%. What do you think?"

107的射程是8.5公里，提30%就是11公里，比现在这个130都大了。

Gao Zhendong was a little amused. If you say you are greedy, you know how to restrain yourself and only ask for 30% after considering various conditions. If you say you are not greedy, you are still talking about 130, but you have already set your sights on 107.

However, he was quite happy about this matter, but he did not take on too much responsibility, in case Comrade 107's rocket engine was already well designed, and the potential of the minor operation was less than 30%.

"Even so, I can't guarantee 30% because I haven't seen the design of the 107 rocket engine yet, but please ask them to come and exchange ideas. No problem, I can arrange it at any time. I'll do my best."
