Chapter 682 It seems that the sea area is very important

The leader of the Defense Work Committee thought about it and discussed it with the chief engineer and the representative of the user.

After hearing his words, the user's representative showed surprise and joy on his face and nodded repeatedly.

Finally, several people made the decision.

Said a few words to a conference staff member.

The conference staff went out and the meeting continued.

Gao Zhendong was editing the "System Analyst Textbook" in his office, preparing to make a bigger one for computer science students. Then he received a call from the Defense Work Committee, calling for an emergency meeting and rushing over immediately!
Gao Zhendong packed up his things and ran away without saying a word.

The GAZ-69 sped along, honking its horn, and reached the Defense Work Committee at the fastest speed.

The comrade who received him invited him to a room. There were several soldiers guarding outside. The room should be a confidential room. The walls and door looked very thick, and there was not even a window. There were tables and chairs, a telephone, and basic paper and pen, but nothing else.

The receptionist asked him to wait here and then went out.

Huh? This kind of meeting is rare, Gao Zhendong feels very novel.

At this time, in the meeting room, a conference staff member said something in the leader's ear.

The leader raised his hand, temporarily stopping the comrades in their heated discussion, and said, "Well, there is a special comrade today. For various reasons, he cannot attend the meeting, but I have invited him to the Defense Work Committee to listen to his thoughts from the internal confidential call. It may not be correct, but it has certain reference value."

This is the solution the leader came up with, a telephone conference, and Gao Zhendong did not attend the whole meeting. He just expressed his opinions based on a few basic issues here, and left after expressing his opinions. Apart from the questions and what Gao Zhendong himself said, Gao Zhendong did not understand anything else in the meeting.

This will cause the least trouble, but I believe the gains will be significant.

Gao Zhendong has always been good at "creating something out of nothing" in terms of technology. That is, even if you don't have this demand, he can create the demand for you, and you still think it makes sense.

His ability is very fascinating.

Besides, Gao Zhendong's current identity is not suitable for attending this meeting. At the same time, the confidentiality level of many comrades at this meeting is not high enough to know Gao Zhendong. If Gao Zhendong really wants to attend the meeting, both parties have to go through the formalities.

As for calling Gao Zhendong over to answer the internal confidential call, it was because such matters, even if they were confidential channels, were unnecessary risks, so it would be best if he could be invited over.

Please listen to the question... No, no, wrong, try again!
"Comrade Advisor, what range do you think is more suitable for ballistic missiles? In other words, given our current conditions, what range of ballistic missiles should we develop is the most appropriate?"

Although he didn't call him by name directly, it turned out that Gao Zhendong actually had a certificate as a technical consultant of the National Defense Work Committee.

Hearing this question, Gao Zhendong was delighted. He knew that they could not hold back. After they had dealt with the short and medium-term problems, they began to take a long-term view.

It's just that he needs to think carefully about this issue.

"I need to calculate and think about this question."

Wow, this guy sounds quite young. Maybe it's just the way his voice is. Some people can't tell their age by their voices, so they could be anywhere from 20 to 45.

It’s just like some people look old, they look like that at 18, and hey, when they reach 48, they still look the same. Gao Zhendong had a classmate like this in his previous life.

The comrades at the meeting were very curious about who this person was, but it sounded like he really had done some research and had some ideas on this issue.

Not speaking out without thinking or blurting out the answer actually shows that you have some thoughts. This issue is too big and too important, and it would be a bit frivolous to speak out without thinking and thinking about it.

In his storage room, Gao Zhendong spread out a map with his consciousness and began working on it.

This is a very troublesome thing. He doesn't have a map on his computer, so he can only measure the distance directly with a distance measuring tool.

The flat map is transformed through spherical projection. The nearest route measured directly on the map is not actually the nearest route. The nearest route on the sphere is actually the great circle route. However, when the great circle route is projected onto the flat map, it becomes very exaggerated and it is difficult to calculate.

Fortunately, Gao Zhendong himself already remembered a lot of relevant data. After all, he was an old military fan and had done a lot of things like drawing lines on the map to see the coverage of war drum XX.

Moreover, his brain was very useful, and he could quickly calculate what needed to be calculated.

Everyone felt that they had not waited too long, as Gao Zhendong's voice rang out from the speaker connected to the phone.

"I think it should be divided into several stages. 1700, 3500 or 4500, 8500, 11500, 14500."

"Oh? Can you tell me the reason?" Seeing that he spoke very convincingly, the leader of the Defense Work Committee asked with a smile.

"There's no need to talk about 1700. We have everything, and it's clear what we can do."

"3500, can cover the core cities of major neighboring countries and the bases of the second island chain in the Pacific. Of course, if there is room for maneuver, 4500 is recommended. In this way, this level can provide better coverage and there is no need to consider using long-range missiles to hit medium-range targets. Otherwise, some medium-range targets will have to be hit with 8500 long-range missiles, which is a bit wasteful."

3500 can cover the entire territory of Tibet, the capital of the Russians, an important node in the second island chain of the Americans, and the entire Nanyang.

4500 can cover all important targets south of Dirty Three and the entire oil-producing area of ​​the Gulf of Oil, including the country in the west that is as big as a booger.

After listening to Gao Zhendong's analysis, everyone felt that it made sense. If there was spare capacity, then 4500, if not, then 3500. After all, the areas covered by more than 4500 were of little significance at this stage. However, Gao Zhendong's next words were full of murderous intent, and every sentence was about the same goal.

"With 8500, we can cover all of America's targets in the Pacific Ocean from our northeast, as well as the northwest part of America's homeland, including the area near the North Pole."

When discussing this issue online, people generally say that 8000 kilometers can cover the west coast of the United States. In fact, this statement is not very complete. Due to the great circle route, 8000 kilometers can only cover the northern two-thirds of the west coast of the United States in the northeast and the northwest corner.

8500 kilometers can basically cover the entire west coast of the United States in the northeast, including its northwest part, but it just needs to choose the position.

"11500, can basically cover the entire territory of Taiwan from the northeast! And can cover parts of Taiwan's west coast in our southern waters."

"14500 can cover the entire territory of the United States in most of our territory, and this range can also cover the entire territory of the United States in our southern waters, which is very important."

Hiss~~~~~~Many comrades took a deep breath. This consultant comrade was very murderous.

But the emphasis on the southern waters is very confusing, and no one knows what he means.

“Why the southern seas?”

Many people still haven’t thought about going underwater, and they don’t know much about its uses, and they don’t think so much about it.

Gao Zhendong laughed on the phone: "Because our inland sea is too shallow."

He didn't say more.

The sea east of the capital is our inland sea. In terms of distance, it is the best launching position, but there is a big problem. The water is too shallow, with an average depth of less than 20 meters. Here, there is no difference between underwater and on the surface, and there is not much cover at all.

After hearing what Gao Zhendong said, the leaders of the Defense Work Committee and the comrades from the user side looked at each other with sparkling eyes.

It seems that that sea area is very important.

The leaders of the Defense Work Committee were even more pleased. They called Gao Zhendong to make a phone call today. They did the right thing! They not only systematically summarized the problem of range, but also made a strong systematic statement with sufficient reasons, regardless of whether it was right or wrong.

As for this 1450... Wrong, the relationship between 14500 and the southern seas is a very important unexpected gain. I really didn't think about it at that time. But now that someone has brought it up, it is worth thinking about it in depth.

But now is not the time to discuss this. The leader of the Defense Work Committee asked, "What about the 500-kilometer one?"

It was very strange that Gao Zhendong directly skipped the simplest short-range missile and did not mention it.

"500 kilometers is too close, and there aren't enough targets. I think 1700 kilometers is a good choice. The largest target requires too much projection, so it's not suitable to use this. If you want to strike with precision, the accuracy is not good enough now. My suggestion is that before ground-to-ground missiles become cheaper to a certain extent and their accuracy is better than 100 meters, don't equip them in large quantities with short-range ground-to-ground missiles. If you have that much money, you might as well invest in some long-range large-caliber rockets."

Long-range large-caliber rockets? It seems that it is possible.

"We won't discuss rockets today. So if we go for 4500, how do we solve the accuracy problem?"

Gao Zhendong smiled: "Actually, the accuracy of 4500 and 1700 is about the same."

This involves a technology that War Drum No. 2 did not use.

Star navigation correction.

Each starlight navigation correction is equivalent to clearing the accumulated error to some extent, and the error accumulates again after the correction.

Loosely speaking, with this combination of technologies, the accuracy of medium-range and intercontinental missiles is only related to the accuracy of the inertial navigation system and the distance to the target at the time of the last star navigation correction.

After saying the above sentence, Gao Zhendong became excited.

"For a range of 4500, it is possible..."

"Beep...beep...beep..."

Bang! The call was cut off, and Gao Zhendong was confused as he held the beeping phone.

What do you mean? Even if you think I'm bragging, you don't have to hang up the phone.

At the meeting, the leader of the Defense Work Committee slammed the telephone hook and looked at everyone with an embarrassed look on his face.

"Well, the following words are not suitable for everyone to listen to together. Haha, comrades all understand, right?"

There was a burst of laughter at the scene, and after the laughter there was admiration.

This mysterious comrade on the phone is really amazing. He can just talk casually and turn it into a top secret.

The one who can make people present unable to listen together is probably at this level.

The leader of the Defense Work Committee answered the call again: "Comrade Consultant, we are not going to discuss the specific technology today. Do you have any other opinions or suggestions? Let's talk about it together."
