Chapter 922 The rest is easy
"That's right. I don't mean for you to do it. Let other comrades do the liquid-fuel missiles as well."

The news about Gao Zhendong could be heard over the phone, but the comrades could no longer laugh when they heard it.

Oh shit, this is even more excessive. We have to set up another organization to make liquid bombs, which will be even more expensive.

"Isn't this investment a bit too big?" The leader of the Defense Work Committee frowned.

"Not big. Please ask the comrades who are working on launch vehicles to work on it. Their launch vehicles must be liquid now. The difference between this thing and intercontinental missiles is actually in navigation and guidance. Regardless of solid or liquid, navigation and guidance are actually the same thing. You who are working on solid materials are supposed to do it."

"Comrades who work on launch vehicles are responsible for solving the range problem of liquid-fuel missiles. This is what they are supposed to do. As long as they want to put it into high orbit, they can't get away with it. As for the rest, you can use the guidance system of solid missiles to install it, and you can almost make an intercontinental missile."

Gao Zhendong's words seemed to open the door to a new world.

In fact, our earliest launch vehicles were modified from missiles. Gao Zhendong simply reversed the process.

"Well, that makes sense. The launch vehicle industry is currently developing a series of engines and large-capacity rockets. During the design process, it should be possible to consider the requirements of missiles and reserve some redundancy."

Only then did they remember that the standardization and serialization of liquid rocket engines was also proposed by this comrade on the phone last time.

"Indeed, this may make the structure of the rocket more complicated and the cost may be higher, but it is better than nothing." For some things, cost is no longer the first priority.

"If the solid-state projectile goes well, then we can cancel the transport-to-bullet design. It won't be a big loss."

"This is an interesting idea, hahaha, it is indeed feasible."

In fact, Gao Zhendong didn’t say another meaning. The equipment needs to have multiple legs to walk, but the research unit also needs to have multiple backups.

"Then what do you think about the parameters of the missile with a range of 11500 kilometers?" The leaders of the Defense Work Committee were very interested in this. Gao Zhendong has a smart mind, masters many technologies, and can often consider problems from angles that others can't think of. It is always helpful to listen to his opinions on such important nodes involving the future.

Although this guy often says shocking things, he doesn't just raise questions and make demands. When the existing installation doesn't meet his requirements, he often comes up with a solution to the problem.

"I think the range of 11500 is pretty good..." Gao Zhendong seemed to be thinking about something on the other end of the phone.

11500 can basically cover the entire territory of Citigroup from the Northeast. The cost-effectiveness is very good. Compared with 8000 which is better than nothing, 14500 is too big a step, and it is a very balanced choice.

The leaders of the Defense Work Committee immediately raised their attention to the highest level, feeling that Gao Zhendong seemed to have hidden meanings in his words.

"Really? Then what do you plan to say in your 'but'? Hehehe."

"Well, let me be frank. If it's solid, the size will definitely change. There's no doubt about that. The length is longer than before. I estimate that 18 meters long and a diameter of no more than 3 meters should be a more appropriate size."

The comrades who work on missiles are a little confused. I haven't calculated it yet, but you calculated it first? But think about it, for those who work on propellants, it doesn't seem to be a big deal to calculate the theoretical size of a missile.

In fact, Gao Zhendong didn't do much calculation. He just used a similar missile from his previous life and relaxed the conditions by 10% to 15%. It should be about the same.

However, Gao Zhendong's answer was obviously not a "but". Others might not know, but the people in the Defense Work Committee knew it very well. Gao Zhendong must have something else to say.

"The size is easy to talk about. I just think that the single warhead is worth discussing. Of course, the warhead has not been miniaturized yet, so the weight of the warhead is estimated to be not light. But no matter what, at least while developing the single warhead, planning the pre-research of the cluster three warhead is a more reasonable consideration."

"Cluster 3 warhead? What does that mean?" To be honest, Gao Zhendong's words left his comrades confused. What is this?
"It means dividing one warhead into three, but these three warheads, like a single warhead, hit the same target."

"Wouldn't it be less powerful this way?"

"Yes, but we all know that for the warheads it will use, a single warhead is actually too powerful to hit a certain area within the explosion center, right? Why not split it into several and spread the strike area a little wider, so that it can better strike large cities."

Considering our numbers and policies within a certain time frame, it is undoubtedly uneconomical to consider attacking the enemy's nuclear silos. The number of warheads we have is even less than that of their silos, and the counterattack policy indicates that the silo will most likely be hit by an empty shell.

No one is stupid. The first wave will definitely use this kind of fixed-position bullet.

So when Gao Zhendong said he wanted to attack big cities, no one was surprised.

"Well, that's a consideration. You mentioned clustered multiple warheads, so are there other multiple warheads?" The Defense Work Committee leader always felt that this guy had not dug up all the goods. Since there is an adjective before "multiple warheads", it may mean that there are many adjectives to choose from. And each of these adjectives may be a technical route.

The main thing is the issue of multiple warheads, which is still a futuristic concept now. No one has it. We are just starting out, so naturally we won’t consider this issue.

Sure enough, Gao Zhendong did not disappoint him: "Yes, I think multiple warheads can be divided into several categories. One is cluster type, where all warheads hit one target. One is independently targetable reentry type, where each warhead hits its own target, but the trajectory of its carrier cannot be maneuvered at will. One is mobile type, where on the basis of independently targetable reentry type multiple warheads, the carrier or warhead has a certain degree of maneuverability. The strike efficiency of these three types of multiple warheads is improved layer by layer, but the technical difficulty is also increasing layer by layer."

"Good summary!" The comrades working on missiles couldn't help but applaud. This comrade not only had superb skills and advanced thinking, but also had a clear and progressive approach. He classified the technology, difficulty and efficiency of multiple warheads very well.

The leaders of the Defense Work Committee were also attracted by Gao Zhendong's words. It was obvious to the naked eye that these three things were better than the other.

"What about the separate guidance type..." asked the leader of the Defense Work Committee.

The maneuvering style might be too difficult, but is the separate guidance style possible?

"It is difficult. Besides, I think it doesn't make much sense for us right now. Clustered multiple warheads are the easiest to make. Theoretically, in terms of carrier and guidance system, it is no different from a single warhead. It just needs to solve the problem of miniaturization of the warhead. It is the most cost-effective. Of course, this is just my personal opinion."

Haha, you have too many personal opinions.

"Well, write it down, write it down, and we'll look at the details later."

The Defense Working Committee was very happy. With just a few words from Gao Zhendong, it could be said that it had made it clear what to do with the warheads of strategic ballistic missiles in the next few decades. There was no need for any planning or demonstration.

Because Gao Zhendong describes the problem based on the principle of strike and hardly involves any technology. This inductive description method can be said to be cheating, and you can't get out of this circle no matter what.

"In addition, decoy warheads can also be one of the technologies to be considered in the future. Of course, we don't need it now, and no one can stop this thing now." Gao Zhendong was still unsatisfied, but this thing was indeed too advanced. If it was made now, it would become a dragon-slaying technique. It was useless. It would be better to use these resources to do other things.

"A decoy warhead? If we have the transportation capacity, why not just throw one down?" The leader of the Defense Committee laughed, and the other comrades also agreed.

"The decoy warhead can be much lighter than the actual warhead and does not require too much throwing weight. To put it bluntly, even an inflatable one can be used. It does not require much weight at all. A missile can carry a bunch of them!" There was a hint of smile in Gao Zhendong's voice. No one knew what he was thinking.

"Inflatable? Wouldn't it fly much slower than a real warhead? It would be recognized immediately." A comrade seemed a little confused.

"There is no air resistance in outer space, so they travel at the same speed whether they are inflated or not. Hehe, by the time they re-enter the atmosphere and burn up, their mission will have been accomplished."

Well, now I know what the special adviser on the other end was laughing at. He should have anticipated this situation - some people just couldn't figure it out for a while. Outer space and the atmosphere are two completely different things, especially for those who work on missiles.

The leader of the Defense Work Committee: That was a close call.

"Well, this can indeed be considered as a long-term technology. Make a note of it."

"But these are all minor matters. I think the most debatable thing is accuracy."

So you've been talking for a long time but haven't yet mentioned the thing you want to complain about the most?

"Accuracy? From a theoretical point of view, an error of 1 kilometers over 2.5 kilometers is already a very high accuracy. Ultra-high-precision gyroscopes are too big to be installed on missiles, and the error of inertial navigation is not small. Even with starlight guidance, it is still a very difficult task."

The comrade who was working on the missiles groaned.

"I know, but Starlight Guidance is actually capable of continuously correcting errors. Although it has its own errors, it can control the cumulative error within a certain limit, right?"

"Correct."

Some comrades did not know how this consultant could tell the details of Starlight Guidance so easily, but some comrades knew very well that Starlight Guidance came from here. That was why Gao Zhendong’s Senior Brother Zhang and others did not come, otherwise they would have recognized Gao Zhendong’s voice long ago.

"So the rest is just a matter of having a good enough, small enough gyroscope, right?"
