Siheyuan: I eat melons while doing scientific research

Chapter 1120 Redefine the mid-range, roll up!

It seems that we can save some time, the leader of the Defense Work Committee thought to himself. It's not that he is superstitious, but mainly because he has seen this kind of scene many times.

"You say, Comrade Zhendong."

"My suggestion is to proceed in two steps. Based on the current missile, replace the rocket engine and make necessary improvements to produce a real medium-range missile. Then, based on this medium-range missile, develop a long-range, high-altitude missile."

Gao Zhendong is preparing to take the path of the Citigroup's "Standard" missile.

"Real medium-range?" The leader of the Defense Work Committee looked at Gao Zhendong with a joking expression. When it was time to be bold, Comrade Gao Zhendong was really bold.

"Yes, I think that 30 kilometers is only the lower limit of medium-range missiles. The upper limit of the range of a true medium-range missile is 70 kilometers. Anything beyond this range is a long-range missile."

With a "wow" sound, the whole audience was shocked. This requirement was too high!

You should know that the S-75 and its brother brother Jingqi-1 in our hands now have a range of only 30 kilometers and are already called medium- and long-range missiles. But he has raised the upper limit of the medium range to 70 kilometers in one go!

Sure enough, Comrade Gao Zhendong is different from ordinary people!

"70 kilometers? Such a high requirement? On what basis did you divide this distance?" asked the leader of the Defense Work Committee. There must be some reason. This is a serious discussion about the division of equipment specifications. It can't be as simple as just talking about it.

Even though we know that Gao Zhendong must have had his considerations, this consideration must be made clear to everyone and everyone must be convinced, otherwise the work of the comrades working on air defense missiles will become difficult.

"My classification method is very simple. The distance at which the enemy can accurately launch an attack on our ground and sea forces is the lower limit of medium-range air defense missiles. The distance at which the enemy can launch an attack with a higher hit rate is the upper limit of medium-range air defense missiles."

This statement is quite scientific, but it is not right. The comrade from the Air Equipment Bureau raised his own question: "But Comrade Zhendong, 70 kilometers is far beyond the distance at which the enemy can attack us. Even at 30 kilometers, it is difficult for the enemy to launch a high-hit attack. It's not me..."

Having said this, he seemed to remember something and froze.

As expected, Gao Zhendong smiled and said, "Why should we use the enemy as a reference standard? What is the range of our air force's laser-guided bombs, TV-guided bombs and other long-range projection weapons?"

The comrades were silent. Damn, he's waiting here.

The upper limit of the effective range of these things is really around 70 kilometers. Taking a little margin into consideration, 70 kilometers is just right.

"This... Comrade Zhendong is right. We should be lenient in predicting the enemy's situation. We should be lenient in predicting the enemy's situation." The leader of the Defense Work Committee said with a wry smile. Why do we have it but the enemy doesn't?

"Well, yes, Citigroup's technology is still very advanced. If it is not available now, it will always be available in the future." A comrade nodded and sighed, saying that Comrade Zhendong really considered things in a long-term and comprehensive manner.

In fact, it's not just the Americans. If we really talk about the sea, the range of the Americans' air and ship weapons is insignificant in a short period of time.

Comrades spoke one after another, and they all felt that Gao Zhendong's calculation of 30 to 70 kilometers was very reasonable and well thought out.

"Okay, then we have decided that from today on, the classification method for air defense missiles will be based on the range proposed by Comrade Zhendong." The leaders of the Defense Working Committee discussed it with comrades in the army and decided to follow the advice, officially starting the study on the range of air defense missiles decades ahead of schedule.

Gao Zhendong listened and laughed, this meant that there would be no need to introduce Type 956 destroyers in the future, otherwise the basic model "Shikili" would not be able to reach this range.

Thirty years in the east, thirty years in the west, don’t be bullied by the poor.

After solving the range classification problem, the comrades turned their attention back to the development of missiles: "Comrade Zhendong, do you mean to use a basic model to slowly develop a whole set of medium- and long-range air defense missiles?"

Gao Zhendong nodded: "This is simpler to do, and it can save money and investment. In addition, the inheritance is orderly, the compatibility is good, and waste can be avoided to the greatest extent. Before the potential of a missile is exhausted, at least in terms of pneumatics, there is no need to invest too much. One missile with multiple types, step by step, is still very useful for our current assets. Even for this 30-kilometer missile, I don’t recommend stopping production immediately after the new missile comes out, but using it mixed with the new missile."

It is still a long way to go before the potential of this missile is fully used up. At least Gao Zhendong never saw it fully used up in his previous life.

At least when it comes to naval air defense missiles, the Citigroup has done a pretty good job. With the same basic missile architecture, it has developed a huge family of medium-range, long-range, ultra-long-range, semi-active, active, air defense, and anti-missile missiles. These missiles can even hit small boats.

As for why the land is patriotic...

Well, it’s too uniform. What does Commissioner Smith eat?
Besides, it's no secret that people one, two, and three don't like each other. Universal? You're dreaming.

At least Gao Zhendong knew in his previous life that our own No. 9 and No. 16 bombs are widely used by both the navy and the army, and any other reasons are nonsense.

"Well, Comrade Zhendong's suggestion is good. This way, whether it is ship-to-air or ground-to-air, medium-range or long-range, we can concentrate resources and come up with the best solution."

"I agree……"

"Indeed, this way of walking is steady, the performance is sufficient, and it can solve big problems without investing too much effort and resources."

"..." Listening to the optimistic speeches of his comrades, the leader of the Defense Working Committee was stunned for a moment. He didn't know how the major equipment problem of air defense missiles became so easy. Even the comrades could be picky and didn't have too high requirements on the progress.

By the way, the basis of all this is the backup missile, which has a range of 30 kilometers!

With this foundation, comrades can discuss so easily. At worst, they can use the worst option, and this worst option is actually the best option in the world at present.

Looking at Gao Zhendong with a smile on his face, the leaders of the Defense Work Committee also relaxed. It could be said that this scene was almost caused by him.

The scene was harmonious, but some comrades remembered what Gao Zhendong had said earlier: "By the way, Comrade Zhendong, you said that you don't recommend stopping production of the old medium-range missiles immediately after the new medium-range missiles come out. Why is that?"

This question involves an inside detail that only Gao Zhendong and a few other people know.

Gao Zhendong said: "Because this new bullet will be very expensive, very expensive. So my suggestion is that this new bullet should only be used for the longest range and most special purposes."

The price of GAP propellant is incomparable to that of ordinary propellants.

There is another reason that Gao Zhendong cannot elaborate on, which is that for a long time, it is estimated that GAP may not be able to get a turn to use air defense missiles, especially after the medium-range air defense missiles with a range of 30 kilometers have been provided as a backup.

The comrades in the Air Force immediately jumped up and down: "What about the missiles with a range of more than 45 kilometers?" From what Comrade Zhendong said, long-range ones might still be available, but there might be no missiles that can be directly replaced with propellants?

Gao Zhendong smiled and said, "There will always be a way, there will always be a way."

"Well, we will discuss the details later. Anyway, the general direction is like this!" The leader of the Defense Work Committee interrupted him. Well, today's meeting was quite fruitful.

Seeing the leader's behavior, some comrades seemed to understand something, yet seemed to understand nothing.

"Chief Engineer Gao, we will start preparing for the finalization of the medium-range semi-active radar air defense missile when we return. Don't forget to come and give us guidance when the time comes." The comrade from the Guidance Research Institute said to Gao Zhendong cheerfully when he left the meeting room.

It is obvious that Gao Zhendong must be one of the personnel responsible for finalizing the design and appraisal of this missile, and he is the technical leader, so his advance invitation will definitely not be in vain.

Gao Zhendong also nodded: "Okay, see you then."

Just as Gao Zhendong was about to leave the Defense Work Committee, he was stopped by the committee's leader.

"Come to my office."

The two sat down in the office, and the leader spoke first. This first thing was what the chief specifically asked him to do.

"Comrade Zhendong, get ready immediately and go on a business trip with me tomorrow."

"Going on a business trip? What's the matter?" This was a bit sudden, and Gao Zhendong was a little stunned.

"You'll know when you get there. It's a good thing! It won't take long, just a few days. Don't worry, it won't delay your work." The leader smiled happily and kept the secret.

You always keep me in suspense, this time it's my turn!

Gao Zhendong nodded in agreement. It was not a big problem. It would only take a few days. I had 60 days and could afford to go!
After the most important thing was decided, the leader smiled and said, "Tell me, what do you think about the medium-range air defense missiles?"

Gao Zhendong reminded him just now that the thing is indeed expensive and the production volume is not high. It is indeed difficult to use it in large quantities on air defense missiles.

Gao Zhendong smiled and said, "It's nothing, I just think GAP is too expensive. It's really difficult for us to use it widely, so I bought a new one not long ago!"

What? You got a new one?
The leader's eyes widened, he couldn't believe his ears at all.

He knew very well how busy Gao Zhendong was at work. How did this guy squeeze out the time?

That's right! It should be when I go home, and I should spend my time on this after I go home. Look, Comrade Zhendong's decision not to move is indeed beneficial. What if the environment changes and affects his mood?

"Can this new propellant be cheaper?"

Gao Zhendong nodded: "It is much cheaper and easier to produce. The performance is a little worse, but generally speaking, it is not much different. It is sufficient for ordinary tactical missiles."

The price of this GAP thing is really a bit high, and NEPE is also expensive, but HTPB, which was widely used in his previous life and is much cheaper, has become more popular.
