Chapter 1267: 1 Nuclear Strike

In fact, at this point, Chang Haonan had already laid all his cards out in the open -

Even the solid rockets and modular satellites, which are of top priority, have been displayed at the Singapore Air Show.

But one of them is a small-scale model, and the other is even just a display board.

Based on past experience, this type of display often means that the product has not yet been put into production, so the very few people who have been attracted to it are like Tim Bodie in the past, who treat this thing as a ballistic missile and come to watch the fun.

Only one wealthy man asked very seriously whether he could purchase a few missiles in the name of launch vehicles and then make modifications on his own after returning.

In the end, the answer was, of course, no.

After all, China today is no longer short of the billions of dollars in cash it once had, and the sensitivity of its long-range missiles that can hit targets at a range of about 8000 km is not comparable to that of the medium-range missiles of the past.

But apart from one insignificant episode, this rocket model, which had not yet been officially named, did not receive much additional attention.

The few media outlets that reported on the Chinese delegation only mentioned it in a few words at most, and believed that this might be a sign that after the split of China Aerospace Science and Industry Corporation, China Aerospace Science and Industry Corporation would return to the orbital transportation business and prepare to compete with its sister units.

It should be said that their guess was not wrong.

I just completely underestimated the efficiency of China...

……

2006 8 Month 15 Day.

In a general assembly workshop affiliated to China Aerospace Science and Industry Corporation.

Like every normal working day, a group of technicians wearing full protective work suits and whose faces could not be seen at all filed in through the door.

But judging from the several cameras following around and the crowds that gathered immediately after entering the room, this should have been a pre-arranged visit for leaders.

The two people walking at the front of the team, with a clear distance between them and the others, were Chang Haonan and Yin Liangxing.

In the workshop behind them, there were three missile-shaped objects lying flat. Their overall appearance was similar, except for their heads which were obviously different.

The body of one of the missiles was still divided into three parts, and the outer shell showed a slightly shiny metallic color, which showed that it was obviously still in the final assembly preparation stage.

But the other two, which were slightly top-heavy, have basically been assembled into a complete form.

However, it was not painted dark green or black like common ballistic missiles, but instead adopted a gray and white paint scheme that is no longer common in this era.

In addition, on the fairing, which is obviously thicker than the projectile body, there are two CASIC logos and two national flags.

Obviously, this is not how a ballistic missile deploys.

"Commander, these two are the 'Kuaizhou-1' solid-fuel carrier rockets that we developed specifically for this type of quick launch mission with a short preparation time..."

As the host, Yin Liangxing first began to introduce the situation:

"Of course, as you can see, this model is actually developed on the basis of the Dongfeng 31 missile. The Yao-31 missile on the left, which is planned to be used for space fishing boat missions, is directly modified from a Dongfeng missile that is about to roll off the production line."

"In order to improve the efficiency of research and development as much as possible and ensure the reference of launch data, the first two stages of the rocket are basically kept as is in terms of hardware, and only the third stage and the upper stage are redesigned... As for the more specific situation, Academician Chang will introduce it."

Chang Haonan was about to speak according to the pre-rehearsed steps, but was interrupted by the leader who was walking in front of him with a wave of his hand:

"I saw in the report Liang Xing submitted earlier that the launch of this model can provide experience support for the future improved Dongfeng 31 missile?"

Yin Liangxing, who had already taken a step back, had no choice but to speak again:

"That's right. We hope to achieve not only an improvement in the range of the DF-31A, but also a leap in the circular error probability (CEP) to enhance the strategic deterrence of nuclear counterattacks."

"But even if Academician Chang develops a new energy management algorithm, in order to ensure sufficient reliability, a large amount of measured data is still needed. Given my country's current national conditions, frequent test launches of ballistic missiles are not allowed either politically or economically. That's why we proposed to accumulate launch experience and parameters in the name of rocket launches... Of course, we can also compensate some funds to feed back the research and development of missile weapons."

The leader nodded, but did not ask any more questions immediately. Instead, he went to the junction of the second and third stages of one of the rockets and looked at it carefully for a while.

Compared with the DF-31 missile with a conical fairing a little further away, the details of the two Kuaizhou- missiles at this connection are obviously different.

"Commander, this is a technology that has been verified for the next generation of intercontinental ballistic missiles..."

Seeing that the leader was interested in this, Chang Haonan immediately changed the pre-arranged order and introduced to the other party:

"The interstage separation technology we currently use on missiles is similar to that used on launch vehicles, with explosive bolts as the connection device and reverse thrust engines as the power source. This technical solution has large separation power and high action reliability, but the explosive force of gunpowder is uncontrollable, which not only makes it difficult to achieve precise control of the separation force, but also interferes with the flight attitude of the rocket, especially the three-stage rocket."

"In order to ensure the accuracy of the Kuaizhou-31's hit... orbital insertion, we adopted a cold separation scheme with a spring separation push rod, and took the residual thrust of the lower stage into consideration at the beginning of the design to avoid the separation collision accident that occurred during the test launch of the prototype missile..."

"..."

By the time Chang Haonan finished introducing all the contents, the leader had already led his group to the end of the two rockets.

"The properties of the propellant remain unchanged?"

Compared with the basic model, the core appeal of DF-31A is still the improved range.

After all, if you can't reach the target, no matter how accurate your shot is, you can only watch.

"Yao-31 and Yao- still use the same propellant configuration as the basic DF- model, but at the software level, the new energy management system allows a glide segment to be added between the first and second stages for online flight trajectory optimization, which can widen the launch window and improve the position accuracy of the rocket during stage separation."

"It is expected that starting from the Y31, the new solid rocket engine and next-generation solid propellant similar to the DF-A will be used... However, this type of solid launch vehicle is mainly used to launch small or micro satellites into low orbit, so the improvement of its carrying capacity is not urgent."

The chief nodded and didn't ask any new questions for a while.

This is a signal.

A signal to others behind you that it's okay to speak.

"Comrade Haonan, what does it mean...the position accuracy of the rocket during stage separation?"

Since this rocket is related to the new generation of intercontinental ballistic missiles, Jing Zhiyuan, the head of the Second Artillery Corps, is naturally the most concerned.

"Uh……"

Chang Haonan organized the language a little:

"That is to say, each stage of the rocket can fall to a more accurate position after separation, so as to avoid the situation where the landing area is too large and the debris smashes the villagers' houses... You know, solid propellants are not like liquids. Even after burning out, they may still be dangerous..."

In fact, this upgrade was something he did naturally.

There is no particularly obvious significance for ballistic missiles, or any solid rockets.

But it is the prerequisite technology for rocket recovery and reuse.

However, this matter seems too long-term at the moment, so Chang Haonan is not planning to make any promises for the time being.

So that others don’t keep worrying about you.

Sure enough, Jing Zhiyuan did not ask any more questions. Their ballistic missile troops basically conducted test firings in uninhabited areas or directly into the sea, so they did not need to worry about destroying the houses of their fellow villagers.

Instead, something else is more important.

"Comrade Liang Xing just said that he hopes to make a leap in the circular error probability of the Dongfeng 31A..."

When he said this, Jing Zhiyuan's eyes lit up:

"Then if we can accumulate a large enough amount of data, theoretically, to what extent can this error be reduced?"

I actually asked him that.

Not long ago, Chang Haonan took advantage of his free time to conduct several simulation assessments with the Second Academy and the Ninth Academy of China Aerospace Science and Industry Corporation.

"Ideally, a CEP of about 50 meters can be achieved..."

He paused for a moment:

"That is to say, the Dongfeng 31A will have a certain ability to carry out a nuclear strike mission, directly threatening the enemy's reinforced nuclear missile silos..."
