Chapter 791: Huge waves ashore

Of course, they will not agree to this immediately, and it will take a long time for them to make a decision. Anyway, they are not in a hurry.
And Huang Lao on the side was very interested in Qin Guan's thoughts: "Mr. Qin, you said that our submarine-launched missiles can also go to land?"
If it is only a submarine-launched missile, it is not equipped with much. A nuclear submarine is equipped with a dozen or so at most. If it is on land, it will be equipped with more. After all, the cost of submarine is high, and the one on land Launch the car, how many are there?
Qin nodded his opinion: "Yes, our Dongfeng-3 can be launched by maneuver and towed away, but it is a liquid rocket engine and takes a long time to prepare. The only way to change it to a solid model is to tow and run. It’s much more efficient if it’s erected."
Think about Dongfeng 21 in future generations. That is the great weapon of the great power.
In 1984, the country held a military parade. If at that time, it showed its solid ballistic missiles, it would be a sensation!
There are two ways to launch a missile. One is towing the head, and the latter is just a trailer. This way, it can only travel on roads and does not have the ability to maneuver in the wild.
One is the off-road chassis with all-wheel drive. These are all professional. Modification of ordinary car parts is not possible. Qin Guan yearns for the latter method.
There are many such strategic materials in the weapon cemetery. As long as you exchange one and let the Northern Heavy Truck Factory refit, that will be enough.
The biggest feature of the land mobile launch vehicle is its concealment, and it is impossible for the enemy to find it.
If the enemy wants to carry out a nuclear strike, the first target is its own missile launching position. Those fixed silos have the lowest survivability and are the first targets to be hit by a nuclear attack.
No matter how well the silo is camouflaged, the enemy's reconnaissance satellites will conduct daily investigations and the enemy's intelligence personnel will be able to find them every day.
Although there may be camouflaged silos, at most it is just a waste of some missiles from the other side, and the real and the fake bombs together.
Mobile launch is different.
These vehicles usually travel back and forth on the road. The reconnaissance satellites in the sky can tell where they are, even if they can track them, drive into a cave, and when they come out again, they will come out from another secret exit in the dark. It disappeared completely.
If you want to track a huge mobile launch vehicle, it is simply an impossible task. If there are some fake vehicles posing, it will make the enemy more helpless.
As long as they are not sure to kill all their nuclear weapons in the first round, they will not dare to attack. This is the origin of nuclear deterrence. You can destroy me, and I have the ability to destroy you.
"Yes, it is a good idea to let the submarine-launched missile land ashore." At this moment, a voice came from behind.
General Ye turned around here, and returned to the table here. Hearing Qin Guan's words, he immediately agreed with him. This matter was of great significance.
"Mr Qin, let's point to the North Industries Corporation for the corresponding missile launcher." General Ye continued.
The people present can be responsible for the missile. Of course, the most advanced domestic heavy-duty truck manufacturer must be found for the launch vehicle. After all, the missile launcher is also a heavy-duty truck.
Qin nodded his opinion: "As long as we give us the technical parameters of the missile, we can develop the corresponding heavy trucks, and we promise to complete the task."
"Although it is more convenient to equip it on submarines, it is impossible for our country to produce a large number of nuclear submarines." General Ye continued.
At this moment, Qin Guan suddenly thought of something: "It's not just the production of nuclear submarines. Our country's nuclear submarines seem to be relatively loud, right?"
Now, the country’s first-generation nuclear submarine is still completely top secret, but this does not prevent the Western world from speculating about Han’s nuclear submarine.
In the underwater world, the radar cannot be used, the only thing that can be done is to listen to the sound.
For a submarine, the vibration of its own engine will produce sound, the propeller at the tail will produce sound, and the movement of the hull and the friction of sea water will also produce sound.
Therefore, technical experts from various countries have spared no effort to reduce this sound. The most common methods are to install rubber shock absorbers on the engine, which is not rigidly connected to the hull, lay noise-absorbing tiles on the hull, and use more advanced propellers.
The submarine must make a sound. This is incomprehensible. If the sound it makes is so low that it is similar to the background noise of the ocean, then it will be difficult for the other party to detect it.
The background noise of the ocean is about 90 decibels. The most common Los Angeles-class nuclear submarine of the Eagle country is 128 decibels. The bear country’s is larger, exceeding 130 decibels, while the Han-class submarine of the Han country has a noise of 165 decibels.
What kind of number is this?
If the Yingguo people squatted two hundred nautical miles away in Han's submarine port, they could hear the movement of the Han's nuclear submarine, and the Han country's nuclear submarine found the Yingguo's submarine at a distance of no more than 50 kilometers.
It can be said that Han's nuclear submarines have only solved the problem of existence. The technology of Han is backward.
When thinking of this, Qin Guan suddenly remembered another thing: "General Ye, although we cannot build a large number of nuclear submarines, we can change the performance of our nuclear submarines. For example, in simple terms, as long as we Processing the seven-blade large skew propeller can greatly reduce the noise of our submarine."
When referring to the propeller of a submarine, it is bound to mention a large seven-leaf oblique.
Ordinary submarine propellers, which are three-blade propellers, are low in efficiency and must rotate at a high speed. After the speed is high, the propeller stirs the sea water and makes a louder sound. At the same time, the circumferential load of the propeller blades is uneven, and cavitation, buzzing and vibration will be generated when rotating, and high-intensity noise will be emitted.
If it is changed to seven leaves, the efficiency is high, the speed is low, and the sound is low. At the same time, this large side is also to further reduce the noise and achieve the most perfect solution. It can be said that the use of large skew, variable pitch, multi-blade propellers can improve the water flow and pressure state at the blades, reduce cavitation and reduce propeller noise.
Unfortunately, Han does not have this processing technology.
Submarine propellers are made of a whole piece of special alloy, usually copper alloy, and then cut out on a machine tool. Ordinary three-blade propellers can be used on domestic machine tools. However, if it is a seven-blade large skew propeller, Ordinary machine tools can't achieve accuracy at all, and you must use advanced multi-axis linkage CNC machine tools. This kind of complex surface can only be solved by multi-axis linkage.
