Chapter 874

Type 033 submarine is a diesel electric powered conventional submarine imitated by Han on the basis of Xiong R-class submarine in the early 1960s.

During the honeymoon in the 1950s, Xiong Guo provided design drawings and construction equipment for Han R-class submarines. Han began to build its own R-class submarine in 1963, numbered 033.

This submarine is a submarine that inherited the technology of World War II. It adopts the conventional surface line, horizontal rudder at the bow and double shaft and double propeller propulsion. At the same time, it has made a number of improvements on the basis of R-class submarine to reduce the navigation noise by about 20 dB.

Compared with the R-class, its noise is much lower, but it is far behind other advanced submarines.

Now, the submarine is in the state of returning from the water.

In the concept of later generations, submarines seem to be hidden underwater and belong to the role of killers. In fact, of course not.

If it's a nuclear submarine, it's almost the same, but if a conventional submarine is underwater all the time, the precious power will soon be consumed.

Therefore, it usually sails on the surface and only enters the water when attacking the enemy.

Now, the submarine has completed all its training tasks and is returning to the port.

The 6e390c medium speed diesel engine made a clatter sound, and black smoke came up through the exhaust pipe at the top. At this time, on the command tower, a sailor was standing there and looking ahead.

The life of submarine soldiers is the most difficult. It can be seen from the subsidies. The food subsidies for submarine soldiers when they go to sea are the same as those for pilots.

The submarine space is narrow, and even sailors may not have their own place to sleep. They must go to the hot bed and work in three shifts. One person on the bed has enough rest to get up on duty, and the next soldier will sleep.

At the same time, the noise of the diesel engine and the unique smell full of diesel are quite strong. In addition, after diving, if you can't be in the vent pipe state, you have to use chemical methods to produce oxygen. That smell is like entering the production workshop of stinky tofu.

However, if no one cries bitterness, when you become a soldier, you can't be afraid of suffering.

Now, finally back to the port, they can relax. They can breathe fresh air on the command tower, which is the most comfortable.

In addition to the sentinels in charge of the lookout, the sailors lined up to breathe. They were also responsible for looking around.

The bow of the boat splits the waves, and the propeller at the tail rotates rapidly. The waves beat the boat. If the waves are large, they can even hit the command tower. Therefore, the position here is also called a bathtub. A big wave comes down, just like taking a bath.

Two minutes per sailor.

When Wang Bao saw his companion coming down, he finally climbed out excitedly. The air outside was great!

Looking at the sea, he was filled with infinite joy. Although they were also the Navy, they could only stay in the cabin after going to sea. There were too few opportunities to see outside. Now, he can finally look around.

Seagulls were flying in the sky. He looked at the sky and the sea. Suddenly, he felt every hair stand up.

"Report, the boat is on the right side, 30 degrees, five nautical miles away. Something's going on!"

When they let out the wind, they also undertook the task of assisting the lookout. Now, when he said this, the atmosphere became tense.

Hearing his words, the lookout post held a high-power marine telescope and looked in the direction over there. It was also very frightened.

I saw a seagull standing on the sea!

If it stirs its wings, it seems possible to hover on the sea, but now it is squatting and pecking its wings with its mouth. It is very relaxed. Is it squatting on the sea?

Of course not. There's something under its feet!

Wang Bao can't see with the naked eye, but he can see clearly under the high magnification telescope. As a submarine soldier, they are quite familiar with it. It's a periscope!

The other party's periscope is rising and just exposed to the sea. The periscope looks at the direction of its own military port. Just this action, you know that the other party is full of hostility!

Our submarines sail and return on the water. After all, this is our home. Continue to dive. What if they 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 cruise. Therefore, it must be the enemy!

The other party actually raised the periscope in this broad day. There is only one explanation, that is, the other party is monitoring its own military port and may be taking photos. After all, there is a secret nuclear submarine base on its own side, which can be photographed clearly only in the daytime.

At the same time, the other party is too rampant. No one bullies his own side?

"Periscope found, reconnoitering our port!" shouted the lookout post.

When he heard the news of the lookout post, the captain was stunned. Then, he was filled with anger and came to his own door to investigate. How unreasonable!

"Attention, all attention, enter the combat state, enter the combat state, prepare to dive and close the hatch cover!" the captain issued a combat order.

With his order, the personnel on the command tower quickly ran into the command tower. The last person closed the hatch cover and checked it. This is the simplest and easiest to make mistakes. If you forget to close the hatch cover, once the submarine dives and the turbulent sea water pours in, the submarine will have to sink.

Such tragedies have occurred in other countries.

"Turn off the diesel engine and turn on the sonar. Right rudder three, speed two."

With his command, the roar of the diesel engine at the tail disappeared, and the submarine immediately quieted down. The battery took over the diesel engine to power the motor at the tail. The submarine turned and went in the direction of the target.

When the sqz-1 integrated sonar system was turned on, the sonar soldier wore headphones and listened carefully to the sound in the sea water, including the sound of distant sea fish blowing bubbles and the sound of distant cargo ship propeller rotation. In these sounds, 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 light and almost inaudible. After all, for sonar soldiers, they mainly listen to the sound of the other party's propeller. Now, the other party is obviously floating and doesn't start the propeller at all.

However, he can still be sure: "the target is a nuclear submarine, which has not been started at present."

If the other side does not act, its own sonar will not hear the sound of the propeller, but the sound of the primary water pump of the unique nuclear submarine will never be eliminated.

Nuclear submarine, bear or eagle? No matter which country it is, it has seriously violated its territorial waters!
