Chapter 874: Target: nuclear submarine

The Type 033 submarine is a diesel-electric conventional submarine modeled on the basis of the Xiongguo R-class submarine by Han in the early 1960s.
During the honeymoon in the 1950s, Xiong provided the design drawings and construction equipment for the Han R-class submarine. Han Guo began to build its own R-class submarine in 1963, numbered 033.
This submarine can be regarded as a submarine that inherited the technology of World War II. It adopts conventional surface line type, horizontal rudder on the bow, dual-axis and dual-propeller propulsion. At the same time, many improvements have been made on the basis of R-class submarines to reduce navigation noise. About 20 decibels.
Compared with the R-class, its noise is much lower, but compared to other advanced submarines, it has fallen far behind.
Now, the submarine is returning to the surface.
In the concept of later generations, the submarine seems to be hidden underwater and is a killer role. In fact, of course it is not the case.
If it’s a nuclear submarine, it’s pretty much the same, but for a conventional submarine, if it stays underwater, the precious electricity will quickly be consumed.
Therefore, it is usually sailing on the surface, and only when it attacks the enemy will it enter the water.
Now, the submarine has completed all training tasks and is returning to port.
The 6E390C medium-speed diesel engine made a rattling sound, and a puff of black smoke rose up through the top exhaust pipe. At this time, on the control tower, a sailor was standing there, looking ahead.
The life of submarine soldiers is the most difficult, as can be seen from the subsidy, the food subsidy for submarine soldiers when they go to sea is the same as that of pilots.
The space of the submarine is so small that even the sailors may not have a place to sleep on their own. They have to go to the hot bunks and work in three shifts. One person on the bed is enough to rest and get up on duty, and the next soldier sleeps.
At the same time, the noise of the diesel engine and the unique smell full of diesel are quite rich, and after diving, if you can’t stay in the snorkel state, you have to use chemical methods to make oxygen. The smell is like It's like entering a stinky tofu production workshop.
However, no one shouts hardship, and as a soldier, one cannot be afraid of hardship.
Now, they are finally back to the port. They can relax. On the control tower, they can breathe fresh air, which is the most comfortable.
Except for the sentinels who look out, the sailors are all lined up to breathe out, and they are also responsible for looking around.
The bow of the boat splits the waves, and the propellers at the tail are spinning fast. The waves hit the boat. If the waves are big, they can even hit the control tower. Therefore, the location here is also called a bathtub. A big wave comes down, like It's like taking a bath.
Two minutes for each sailor.
When Wang Bao saw his companion coming down, he finally climbed out excitedly. The air outside was simply wonderful!
Looking at the sea, he was filled with infinite joy. Although they were also navy, after going to sea, they could only stay in the cabin. There were too few opportunities to see outside. Now, he can finally look around. Up.
Seagulls were flying in the sky. He looked at the sky and the sea. Suddenly, he felt every hair of his own stand up.
"Report, the right side of the boat, in a 30-degree direction, five nautical miles away, there is a situation!"
When they released the wind, they also assumed the task of assisting the lookout. Now, when he said this, the atmosphere suddenly became tense.
Hearing what he said, the lookout post was holding a high-power marine telescope and looking in the direction over there, it was also extremely shocked.
I saw a seagull standing on the sea!
If it stirs its wings, it seems possible to hover on the surface of the sea, but now, it is squatting, pecking its wings with its mouth, extremely relaxed, is it squatting on the sea?
Of course not, there is something under its feet!
Wang Bao can't see it with the naked eye, but he can see clearly under a high-magnification telescope. As submarine soldiers, they are quite familiar with it. It is a periscope!
The opponent's periscope is rising, just exposed to the sea, and the periscope is looking at the direction of your own military port. With just this action, you know that the opponent is full of hostility!
Your submarine’s sailing and returning are in a state of surface navigation. After all, this is the door of your own home. Continue submerging. What if you hit a fishing net or something?
At the same time, they also know that no submarine has come out recently. They are the only one to come out to cruise, so the enemy must be coming!
The other party actually raised the periscope in this bright day. There is only one explanation. The other party is monitoring its own military port. It may be taking pictures. After all, there is a secret nuclear submarine base on its own side, which can only be taken during the day. clear.
At the same time, the other party is too rampant, do you bully no one on your side?
"A periscope was found and we are investigating our port!" The lookout shouted loudly.
When he heard the news from the lookout post, the captain was taken aback for a moment, and then, a wave of anger surged in his heart, and he came to his door to investigate. It is unreasonable!
"Attention, pay attention to all, enter the combat state, enter the combat state, prepare to dive, close the hatch!" The captain issued a combat order.
Following his order, the personnel on the control tower ran into the control tower quickly, and the last one closed the hatch and checked it was intact. This is the simplest and the easiest to make mistakes. If you forget to close the hatch, then once the submarine dives and the turbulent water fills up, the submarine will sink.
Such a tragedy has happened in other countries.
"Turn off the diesel engine and turn on the sonar. The right rudder is three and the speed is two."
Following his command, the roar of the diesel engine at the tail disappeared, and the submarine instantly became quiet. The battery took over the diesel engine to provide power to the electric motor at the tail, and the submarine turned towards the target.
The SQZ-1 integrated sonar system is turned on. The sonar soldiers wear headphones and listen carefully to the sounds in the sea. There are the sounds of distant sea fishes blowing bubbles, and the sound of the propellers of the cargo ships in the distance. In the sound, he listened carefully, and finally heard the sound of the water pump in the primary circuit of the unique nuclear submarine reactor.
The sound is very soft, almost inaudible. After all, for the sonar soldier, the main thing he listens to is the sound of the opponent's propeller. Now, the opponent is obviously in a floating state, and the propeller is not activated at all.
However, he can still be sure: "The target is a nuclear submarine, which has not been activated yet."
If the other party does not act, then one's own sonar will not hear the sound of the propeller, but the sound of the unique nuclear submarine's primary circuit water pump can never be eliminated.
Nuclear submarine, bear country, or eagle country? No matter which country it is from, it has already seriously violated its territorial waters!
