Super Weapon Swap System

In January 1960, the Machinery Industrial Department held a meeting regarding the "031." The originally planned Shipyard had yet to develop production capacity, so it was not suitable to start construction in a short period of time. The meeting suggested that it should be built by the Jiangnan Shipyard in Hua Ting, but the factory had no time to take responsibility for the construction of the "033" boat.    

Under such circumstances, the leaders of the Shipyard in Binhai City who participated in the meeting took the initiative to volunteer. They proposed to take responsibility for the construction of the "031." After a few rounds of research, they found that there were no problems and gave the task to the Shipyard in Binhai City.    

3rd, Mar., 1960, the "031" boat began to display the blueprints. 1st, Apr., 1960, the order to start building the "031" submarine was officially issued. The construction work number of the factory was "C-601."    

In May, to improve the technical level of the construction workers, Shipyard held machine processing, welding, and heat processing respectively. The specialized technical training courses for installation, debugging, and experimentation of special equipment were focused on the AK-shipped from the Bear Country. 25. AK - The processing of 27 steel plates, welding and use of stainless steel weld, and other aspects of organizing practical technical training, as well as inviting experts from Bear Country to give professional lectures based on the type of work. They were going to pass on their experiences.    

Originally, they were going to make a big deal out of it, but in the end, the two countries were on bad terms. The experts of Bear Country were withdrawn, and the subsequent materials were not transported over.    

Under such circumstances, the Shipyard in Binhai City was ready to fight. After some experimentation, they finally completed the first submarine trial. Originally, they planned to build two of them in the first batch. After that, they planned to build four in the second and fifth phases of the plan. In the third and fifth phases of the plan, they would build 36. However, due to the limitations of the technology, coupled with the fact that they had yet to develop the accompanying stealth Ballistic Missile, the original plan was to build two submarines in the first batch. Therefore, they did not proceed with the construction of the subsequent ships. Instead, they only built one ship.    

This submarine had more than 3000 tons of displacement, which was within the category of large submarines. At the same time, model 033 had less than 2000 tons of displacement.    

At the same time, the most advanced part of it was that it belonged to the Ballistic Missile submarines. This kind of submarine designed by Bear Country was equipped with 3 SS-N-4 launchers. missile length 9. 5 meters, 880 millimeters diameter, 350 kilometers range. Although its performance was not very good, it was still a submarine that could launch Ballistic Missile.    

Although after military service, due to the lack of accompanying missiles, the submarine could only be used for training for a long period of time.    

At the same time, along with Han Country preparing to develop the first generation of latent Ballistic Missile, a large number of underwater missile systems were needed to be trained and tested, and the submarine itself had the ability to launch the Ballistic Missile. Therefore, they decided to use the model 031 ship as the experimental ship, and use it to cooperate with the planned research and development of the first generation of submersible Ballistic Missile in Han Country.    

Under such circumstances, the submarine 031 began to modify.    

The first step was to change the 3 Su Type CM-60 missile launchers on the boat to 2 domestic "giant wave" Type 1 underwater missile launchers.    

The core of the new launch device was to push the missile out of the barrel and shoot the missile out of the water. It would surpass the technical level of the first generation compressed air ejection device and gas ejection device of the submersible missile. Similar to the Ballistic Missile Nuclear Submarine in Y Country, it used the latest gas ejection device. The structure of the system was simple, the missile's overload was small, and the ejection thrust was large. It was equipped with world-class technology.    

After that... After that, in order to improve the missile launch ability under high sea conditions, the boat immediately went through a second modification. After this modification, the ship was also changed to Expedition 200 submarines.    

However, the test launch of the missile was a very complicated process. Every time they came back, they had to improve it. This time, when they returned to Shipyard, they might have to make some major improvements.    

This was supposed to be the highest secret in the country, but Qin Guan's level had already reached. Furthermore, with Qin Guan's participation, perhaps these problems could be solved.    

"President Qin, we still have a long way to go if we want to complete the experiment. Now, we have done enough experiments on the underwater launch. We have accumulated a lot of experience to make the missile successfully come out of the water. However, the location of the submarine is still a big problem. "    

If you want the missile to be accurate, then you must have an advanced positioning system.    

The launch of the Ballistic Missile is a complicated process, the location of the missile. The location of the target, the rotation of the Earth, and other factors were all taken into consideration. Then, the computer calculated the trajectory, when the engine was shut down, when it would enter the atmosphere, and so on.    

If this was not precise enough, then the missile would go over, and the error would be a few thousand meters.    

On land, the location of the launch site was determined. Even if it was a mobile launch site, they would find a certain launch site beforehand, and the coordinates were already known.    

However, it was different on the sea.    

The submarine sailed in the sea and could launch missiles at any time according to the needs. If they couldn't accurately locate their location, then the accuracy of the missile wouldn't be high enough.    

Qin Guan also frowned. "Yes, this problem, let us solve it. We used our own method to obtain some advanced technology from the international market. Then we will hand it over to our technical experts. We hope to develop a laser top as soon as possible. "    

The development of advanced technology was not easy. Up until now, there were still some technologies that were not up to par in Han Country. The inertial guidance system was one aspect.    

Other than submarines, fighter planes and missiles all require this kind of advanced technology.    

The inertial navigation system, the navigation parameter deconstruction system of sensitive components with gyroscope and acceleration as the base. The system established a navigation coordinate system based on the output of gyroscopes, and calculated the speed and location of the carrier in the navigation coordinate system based on the acceleration deconstruction.    

Among them, this gyroscope was of great importance, and the less resistance the gyroscope faced, the better.    

The first one was the Rolling Ball bearing gyro. Its drifting speed was (L-2). degrees / h, this precision was very poor. The first V-2 rocket was this kind of guidance system. With a range of a few hundred kilometers, the error could be more than ten kilometers.    

After that... After that, the accuracy of the gas levitation, liquid levitation, and magnetic levitation gyroscope could reach 0. 001 degrees / h.    

At the current level of Han Country, they were using a floating top. The Long March series rockets used this kind of product, although the accuracy was not low anymore. However, the accumulated error was still considerable. If the submarine was patrolling underwater for half a month, it would not be able to meet the need to launch the missiles.    

This time, they went out for half a month, then came back to readjust the top, and also discussed a solution.    

What was the solution? Of course it was the laser top.    

In 1960, the laser top was first successfully developed. In Western World, this kind of top was widely used for inertial navigation. The western fighter jets, missiles, and so on all used this kind of top.    

However, in Han Country, there was still no technological reserve.    

What should he do? Of course, he would find it from the Weapon Data Cemetery! This crisis was not only limited to submarines, missiles, airplanes, and so on. Qin Guan had already made up his mind. Find the information and hand it to Prof. Lin, the leader of the Han Country's navigation system. If he needed the processing equipment, he would look for it in the lathe cemetery. In short, this technical problem must be solved!    

"If we don't have enough time, we can also import the advanced laser top from the west through certain channels and install it on our submarine. We will satisfy the needs first." Qin Guan added.    

After all, underwater launch experiments were being prepared in full swing. They might not be able to wait for their own research to be completed. It was not difficult to import a finished product from the western market.
