Super Weapon Swap System

The Los Angeles class nuclear submarine is the latest generation of eagle's nuclear powered attack submarine and the product of various advanced technologies in the mid-1970s.

In addition to various shock absorption measures, it also has its unique s6g pressurized water reactor, which is improved from the D2G pressurized water reactor used on the US Navy Missile Cruiser in the 1960s. Its biggest feature is that when the Los Angeles class is sailing at low speed, The reactor on the boat can operate in natural circulation mode without starting the circulating main pump in the primary circuit, so as to minimize the noise on the boat.

For nuclear submarines, the biggest noise sources are two, one is the propeller at the tail, and the other is the circulating water pump of the reactor.

The circulating water pump of an ordinary reactor must be turned on even at the lowest power. As long as it is turned on, it will make noise.

Like the nuclear submarines of the Han Dynasty, the circulating water pump made a huge noise and was discovered by submarines of other countries from a distance.

However, the Los Angeles class has achieved a miracle. In low-speed navigation, the primary circuit of the nuclear reactor has realized the operation of natural circulation, and the circulating water pump does not need to be turned on. In this way, the noise is greatly reduced.

Of course, if you want the nuclear submarine to sail at full speed, the circulating water pump of the nuclear reactor cannot be turned on. At the highest state, s6g pressurized water reactor can provide 35000 horsepower, which can meet the high-speed navigation required by this class of nuclear submarine to perform short-range direct support mission and the low-noise navigation required to intercept enemy submarines.

The Los Angeles class nuclear submarine is the pride of the eagle Navy and a sharp weapon for them to fight bear submarines underwater. Now, it is also a good opportunity for the Han navy to practice.

At this time, underwater, the Los Angeles class nuclear submarine is sailing at a low noise speed of 3 knots, the main circulating water pump is stopped, and the whole nuclear submarine is in silence.

Wearing clean uniforms, Captain bill was calmly directing the submarine forward.

When the bear submarine in front accelerated, Bill found that the situation was bad. After pursuing at full speed for less than three minutes, Bill decided to stop the pursuit.

Now, the bear submarine has had to surface in the explosion of the deep-water bomb. The tragic situation of this colleague makes bill feel the ferocity of the underwater world.

As underwater kings, they must leave here safely. If they are found by the other party and attacked again, they will make a big oolong.

"Sonar buoy, all four directions." just then, as if afraid of what comes, the sonar said the voice captain Bill didn't want to hear.

Xiong Guo's submarines have been expelled. Now, some people are throwing buoys. They must be looking for them!

"Watch out, the propeller stops and we drift with the current," Captain Bill said.

The nuclear submarine has been sailing with low noise. If you want to make the noise lower, you can only stop the propeller. In this way, the nuclear submarine has no sound. It just moves with the ocean current like a whale. This is the quietest.

"The most advanced in Han is the fan hunting anti submarine aircraft imported from NiuGuo. In the past, we could make them return in vain as long as we turned off the propeller," Bill said.

The equipment of the Han state comes from Niu state, while Eagle state and Niu state often hold joint exercises. In Beida Xiyang, anti submarine training is even more common. It is not easy to find them.

If only there are fan hunting anti submarine aircraft, they can't be found. However, if the data link networking has been completed and more powerful and advanced algorithms are available, it's different.

At this time, it was already dark, and the anti submarine at night was even more a test of the combat level of the troops.

"Find the target, direction * *, depth * * *." on the hunting fan anti submarine aircraft, suddenly, the system has screened the target!

"Follow the same pattern and hit two anti submarine deep bombs!" said General Zhao.

When dealing with Xiong's submarines, you're welcome. More than a dozen anti submarine deep bombs have passed. Now, if you know that you are dealing with eagle's Navy submarines, you have to give some face and force them out.

In the dark night, two anti submarine deep bombs dragged flames and flew out of the rocket launcher.

Sitting on No. 111, Qin Guan knew that the anti submarine battle would soon come to an end.

"The technology of these eagle and bear nuclear submarines is quite advanced, and the underwater noise is very low. Our current anti submarine forces can find them. It's really not easy. However, we don't know when our submarines can reach this level."

General Zhao is waiting for the news of the other party's submarine floating. At the same time, he is also talking with Qin Guan about the construction of the Navy.

The nuclear submarines of the Han state have only solved the problem of whether they exist or not. The noise is quite loud. Technology is a role that will be tracked just out of the port. If they are stared at by the other side's surface ships during the war, the end will definitely be worse than the submarines of the bear state and the eagle state.

"Yes, our national defense industry has great defects, especially for submarines. We need our scientific researchers to continue to work hard and study advanced technology." Qin Guan said: "the most important technology on nuclear submarines is nuclear reactors."

When it comes to nuclear reactors, suddenly, the word "high temperature gas cooled reactor" appears in Qin Guan's brain!

The principle of a nuclear reactor is very simple, that is, it uses nuclear fission to generate heat, just like boiling water in a boiler. A nuclear reactor is a large boiler.

Ordinary reactors are pressurized water reactors. Nuclear raw materials are immersed in liquid. The liquid flows. On the one hand, it dissipates heat for the reactor, on the other hand, it will take away heat to heat the secondary circuit and drive the steam turbine.

PWR is already the most mature nuclear reactor in this era. In fact, when scientists first began to study the reactor, they first thought of gases, such as carbon dioxide, for the selection of coolant.

For example, an ordinary graphite moderated core, coupled with several powerful blowers, can easily form a reactor. The structure of electric blower is much simpler than that of the main pump of PWR. The gas-cooled core never has to worry about nuclear leakage, let alone coolant leakage.

In extreme cases, as long as the core is blown, there is no risk of meltdown, and the safety is much higher than the popular pressurized water and boiling water reactors!

Therefore, when developing commercial reactors in the early stage, all countries chose the technical route of gas cooled reactor without hesitation. NiuGuo took the lead and built the first commercial gas cooled reactor in human history. The exhausted empire once again showed the world that its thin dead camel was greater than a horse.
