Back to the Republic of China to be a editor

So, two weeks after the last time, Tang Hua boarded the Moscow-Stalingrad-Kapustin Yar missile launch site train again.The car also has all the equipment of the control room demo2.0.

"Hans, you have been asking about China's anti-aircraft missiles. Why don't I ask you about the situation of the 'Waterfall' missile?"

In the past few days, Hans asked directly and indirectly. In short, he was very interested in a kind of anti-aircraft missile that he believed must exist in China.

"'Waterfall'? Apart from the analog computing circuit I participated in designing, there is not much to say." Hans said honestly, "Also, you have also seen 'Waterfall' in the third special bureau. technical data."

The "Waterfall" air defense missile is developed by Germany and may be the world's first air defense missile. How primitive is it? ——The bomb body is modified with V-2.

Yes, it is the kind of ballistic missile with a range of 600 kilometers.

"Waterfall" is as thick as the V-2, shorter than the V-2, and weighs 3.7 tons, which is lighter and more flexible than the S-25.The maximum range is 25 kilometers.At first, the "Waterfall" planned to use visual tracking and radio command corrections. Obviously, this is an almost hopeless guidance method. The missile and the target are not in a straight line, and the operator can only send control commands according to the feeling. The second-stage improvement of "Waterfall" is back on the right track, radar tracking, analog computing circuit solves output control commands, and sends them to missiles.It was at this stage that Hans joined the Waterfall development team.

In fact, "Waterfall" has a more primitive place, it does not have a proximity fuze...

Proximity fuze, a black technology of World War II, Britain and the United States, has become an eternal pain in Germany's heart.It is said that Britain bought the patent of the most prototype proximity fuze from a German company in the 30s, changed the electrostatic trigger to radio trigger, and then handed it over to the United States, which produced a radio proximity fuze.However, Germany has been walking on a crooked road, and it was not until 1943 that it suddenly realized, but it was too late.Therefore, during World War II, not only all German large-caliber anti-aircraft guns had only timed fuzes, but also anti-aircraft missiles.The Germans planned to hit the "Waterfall" into the heavy bombing fleet of B-17/24. The controller saw that the distance was almost the same. When he pressed the button, the missile exploded in the sky. If he was lucky, he could blow up the plane.

"Hans, the 'Waterfall' system has a missile body and engine that were quite advanced in 1944, and a first-class analog computer at that time, but it cannot be equipped with the radio proximity fuze that has been loaded into the shell in the United States. What does this mean? " Tang Hua asked Hans.

"Illustrate...the 'waterfall' system has many flaws."

"I want to say that the radio proximity fuze is your shortcoming. For the dozen or so subsystems of the entire missile system, the technical level or completion of the fuze lags far behind other subsystems. Even a mature second-tier fuze like Germany The industrial countries after the second industrial revolution were just like this when they developed missiles."

This Tang Hua gave Hans a big hint, and sure enough, Hans quickly figured out the key points. "So, China also lacks some... So what technology do you want to take from the 'Golden Eagle' project, do you need my help? If the technology is available, can I go to China?"

"You...you...if you can leave the Soviet Union, you just need to enter China, and China will take care of your food, clothing and housing for the rest of your life."

Hans and several people who worked with him in the [-]rd Special Bureau now have East German ID cards, but they are participants in the Soviet Union's top-secret defense program, where they can go and where they can't go, not East Germany The government can manage it, but it is up to Moscow to decide.Therefore, it is not so easy for them to immigrate now.

……

At the Kapustin Yar missile launch site, another luxury package of missiles was fired indiscriminately.Now, Tang Hua is no stranger to the huge production capacity of the Soviet Union's military industry. Let's fight, play a few more rounds, collect more test data, and make research and judgment easier or more accurate.

The Third Special Bureau was also anxious. Comrade Stalin personally instructed "develop the missile in one year! One year! One year!" Listen, the Georgian Russian language still carries an echo.

The successful sign of the last missile test was "try to crash all the missiles after they are launched", this time it will be reversed, after the missiles are launched, they will perform various maneuvers according to the control instructions, but first of all, there must be no breakage or disintegration, and secondly , to see the controlled maneuvering of the missile.

So, in the bunker, Tang Hua watched the S-25 sample bombs fly into the sky one by one.Seeing that the first two missiles performed maneuvers accurately, Tang Hua felt bored about the next 10 missile tests, so he put down the binoculars and found a place to rest.

……

"All the tests are done. Although I still have to wait for the high-speed camera video for final analysis, I feel that the system should be normal. Why don't we try the low-speed target drone now?" The chief engineer watched from the beginning to the end in the bunker. Suddenly made this suggestion to Tang Hua.

"What? Does your target drone say you can call it if you want it?"

"It shouldn't be a big problem. You can call the airport now. There are still 8 spare missiles stored here."

The S-25 missile, after the test firing of the control missile, does not have a low-altitude balloon shooting stage, and directly enters the middle-high altitude low-speed target drone target shooting test.

Because the minimum effective combat altitude of the first version of the S-25 missile is 2000 meters...a tethered balloon cannot fly so high.Only low-altitude air defense missiles with a minimum shooting height of less than 100 meters and a maximum shooting height of only 4500 meters need to hit low-altitude balloons.

Tang Hua nodded, and let the Ivans work hard.

The chief teacher shook the phone to inform the shooting range, then turned to Tang Hua and said, "Here we are. After 40 minutes, the target plane will fly over the shooting range."

After the reorganization and design of the computer system is completed, Tang Hua is actually not in a hurry now, just let the missile test site conduct test launches step by step.As for the head teacher who was in a hurry, it was probably because "Siberian potatoes" made him a little bit stressed.

40 minutes later……

Still can't see anything in the sky...

This is not a level target drone in the 20s that Shen Fei picked up from scraps and parts, but a special mid-altitude target drone. Today, the flying altitude is 6000 meters and the speed is 420 kilometers per hour.

If you want to see the target drone, you can only use the high-power automatic tracking optical measurement system, but there is only one in the bunker, and the chief engineer is now lying on the eyepiece and does not move.

"The first shot...I seem to see it...flying towards the target...flying past...Damn it, it must have missed the target drone."

"The second round...flying to the target...the drone...destroyed..."

"Dear Comrade Chief Instructor, in fact, it is not necessary to do the two-stage test on the same day." Tang Hua said, "The deadline given by Comrade Stalin is August this year, and we still have 8 months to complete the test firing and finalization. .”

"No, we don't have enough time." The chief division said to Tang Hua, "There will be many modifications in the future, especially the second plan. The weight of the warhead has changed, and the entire front of the missile may have to be redesigned."

"The weight of the warhead has changed?" Tang Hua suddenly remembered something, and quickly grabbed the chief teacher and continued to ask, "The second plan, is the nuclear warhead used as the warhead of the anti-aircraft missile?"

The chief teacher spread his hands and smiled strangely at Tang Hua.

"2 tons equivalent."

Chapter 126, this missile is paid for by North Korea

"What, the S-25 missile is going to be aided by the Soviet Union to North Korea? Not to China?"

On February 2th, the chief engineer of the "Golden Eagle" project improvised. On the day after the test firing of the test and control sample bomb, another target drone was called to shoot. 20 shots hit 2. Go back and look at the film of the high-speed camera. The shot that missed It is very close to the target drone, and there is a high probability that there is a problem with the fuze and it has not been triggered.This means that the problem of the control system of the S-1 missile has basically been solved by Tang Hua, and now the finalization of the missile is just around the corner - there are still some minor problems that have not been solved, and that is not in the control system.

At this time, Tang Hua was relieved, and when he returned to Moscow, he would have time to find Ambassador Wang Jiaxiang, and by the way, ask Su Yuan what he was talking about now.As a result, Ambassador Wang told Tang Hua that the S-25 missile system was an anti-aircraft missile project introduced by North Korea from the Soviet Union, and North Korean comrades were already discussing this matter with the Soviet Military Industry Committee.

But if you think about it carefully, the S-25 missile system is indeed the business of the North Korean comrades.

Because the S-25 is a fixed surface-to-air missile, it cannot maneuver by road at all, and the deployment of this missile system requires the construction of many ground and underground buildings.Forcing into the missile's control room, Tang Hua's demo version is a room on the ground, but according to the system design drawing, it needs to dig a basement.Not only the control room should be underground, but also an underground bunker-style dormitory that can accommodate 60 people should be dug nearby, and at least two caverns for storing 60 missiles should be dug; each anti-aircraft missile launcher needs to build a road to load the missiles on the trailer Ship it there for loading; the radar needs to be surrounded by a bulletproof parapet; the missile launching device, the radar, and the control value are connected by underground cables.

This kind of missile is deployed in North Korea, so it is naturally a fixed asset of North Korea. After the Korean War, China can't say "this is my missile system. I have withdrawn my troops and dismantled it", and then sent a demolition team to move it back to Shanghai. .Some devices and cables simply cannot be disassembled.

"That's reasonable. The missile...should belong to North Korea. However," Tang Hua said, "since North Korea received the aid, the money should come from North Korea, right?"

Ambassador Wang: "The Soviet Union provides loans to North Korea, and North Korea repays them in ten years."

"Then there is no problem, Ambassador Wang, this is not a bad thing, but a good thing." Tang Hua thinks this is really good news. The S-25 air defense missile system is very expensive.

In the past, a Soviet S-25 missile cost 11 rubles, while a MiG-15 fighter jet cost only 14 rubles.Tang Hua's changes were mainly to upgrade the fire control computer and the analog-to-digital circuit, and did not perform any surgery on the missile itself, so it should still be 11 rubles each.

10 S-25 salvos are fired, which means that 8 MiG-15s are gone.

Others, such as rotating launchers, loading vehicles, search radars, tracking radars, and control rooms, all cost a lot of money, and the construction of air defense system launch positions also costs money.

要知道，部署在莫斯科的第一套S-25防空导弹系统，一共有2部搜索雷达、20部跟踪雷达、2个控制室、60个旋转发射架和120辆装填车，全套价格超过1000万卢布，一次最多可发射60枚导弹，打击20个空中目标。也就是它一次全火力齐射拦截烧掉660万卢布，48架米格-15没了。

Thinking of this, Tang Hua couldn't bear it. "How many anti-aircraft missile systems have Comrade North Korea ordered?"

"Two sets."

"How much loan did they ask for?"

"I heard that it is 500 million, the construction of the missile base is 2000 million, and the rest is the cost of ammunition."

"The price is a bit too high, North Korean comrades have to bear a lot of burden. Let me find a way for them..."

The point is not that North Korean comrades have too many debts. What Tang Hua cares about is that the two S-25 systems are too few.
