Chapter 1249: Keep up

"Execute orders." Ivanov said to his assistant. Submarines often act alone. The captain has absolute authority. It can be said that if his men do not obey the order, he can shoot. As for the captain's command Negligence, at most, after returning to the port, it will be handed over to the military court to judge.
Now, his order cannot be violated.
The elevator of the submarine began to move. The huge hull, with its bow upward, slowly lifted up. As it sailed forward, the depth was gradually decreasing.
"Thirty meters."
"Twenty meters."
"Ten meters."
"Flatten."
Ivanov proficiently gave orders one by one. To operate the submarine, many people are required to act together. These people all listen to his orders. He is the soul of these people. Now, the submarine is at a depth of ten meters. Has been leveled.
"The sonar report, the target is one nautical mile on the port side and is expected to arrive in five minutes."
"Ascend the periscope." Ivanov said, operating the periscope in front of him with his hand, and as the periscope slowly rose, he protruded out of the sea, his eyes fixed on it.
The moon was shining on the sea, and the wind and waves were not too great. He could see the sparkling waves on the sea. In the distance, a dark shadow came slowly, and it was the submarine that was still floating.
The Han State Navy will always be like this, without any combat awareness, as long as its own submarine goes out to sea, the whole time is below the surface of the sea.
There is no way, because as long as they leave the base, they will be caught in endless peek-a-boo operations with the Eagle State Navy. If they dare to sail on the sea after leaving the base, they will simply tell the Eagle State people that they are in There.
At the same time, they are all nuclear submarines. Han's are conventional submarines. For this kind of submarines, water navigation is the norm. After all, they are not real wars. Moreover, they are experimental boats.
"Strange, why is it a lone submarine, shouldn't they be a formation?" Ivanov said to himself, and suddenly his eyes widened.
Under the moonlight, from this angle, he could just see the ship number on the opponent's control tower, 200, just right, that's right, that's it!
The KGB has accurate information for a long time. In order to achieve the goal of launching a launch vehicle underwater, the Han people have carried out research for several years. The submarine with hull number 200 is used. This submarine is still in accordance with Xiong's 031G. It is said that the Chinese people have improved the launch tube for testing.
Now, the hull number of this submarine is 200, which is absolutely correct!
The other party must know that someone will be following, so they deliberately sneak out in the middle of the night, so that they are unconscious, and then they will meet in a certain area.
That's right, that's it!
Now, there is only one task, keep up!
"Attention, two cars, one forward." Ivanov said.
His nuclear submarine can reach 30 knots underwater, while this conventional diesel-electric submarine can only reach 20 knots. Therefore, his pursuit is quite easy.
I just ventured to use the periscope, it was good. Now I can finally confirm the target. Ivanov’s face is full of smiles, retract the periscope, right rudder, and follow!
Underwater games are quite thrilling and exciting, but generally speaking, whoever is behind will be invincible.
It's like fighting with a fighter plane, because the sonar is in front.
The bow of the submarine, in the huge space, is equipped with a sonar ball. The environment here is the best, the quietest, and the lowest sound in the sea can be heard, which is convenient for the submarine to listen.
If the target is in front of you, you can find the opponent's trail steadily, and you are behind the target, facing the position of the opponent's propeller, and the noise there has already covered up all of your own noise.
Catch up steadily until they reach the point where they launch the missile, and wait quietly to watch their launch!
Ivanov thought secretly in his heart.
It's just that he didn't expect that there would be a new kind of sonar, specifically looking for the enemy behind him!
This is of course the drag array sonar.
The technology of the 039 class submarine was at that time spent huge sums of money and was imported from Niuguo. Naturally, it also included the above advanced sonar systems, including the 2046 towed VLF passive array sonar, and the 2040 bow active and passive warning sonar, 2041 Type hull passive array sonar and 2019 type passive ranging sonar.
When it was first introduced, it was naturally for the advanced equipment of this submarine, especially this towed line array sonar that best reflects its advanced nature!
In later generations, this will not be realized until 112 ships, and now it has been equipped on submarines.
It is a sonar that inlays hydrophones on cables to form a linear array, and is towed by the towed cables to detect targets in the water behind the stern of the ship. It is mainly used for listening to submarine radiated noise, remote monitoring, direction finding and identification, and some can also be used for ranging.
Although there is a propeller at the tail, it can continue to rise by hundreds or even thousands of meters! In this case, it is far away from the submarine noise source and has a larger size, so it has outstanding long-range detection capabilities.
The discovery distance of hundreds of nautical miles can only be achieved by this towed line array sonar. The hull of the sonar can find an advanced submarine within 50 nautical miles.
Now, on the 320 submarine, Captain Lei heard the sonarman’s report: "A big fish was found, following us."
Relying on the advanced towed array sonar, the submarine behind with good silent performance was still spotted by the submarine here when it turned.
Sure enough, a submarine was hooked!
"Attention, prepare to dive." Captain Lei issued an order, and the watch post of the control tower was withdrawn, and the hatch was closed. In the waves, the ship number 200 quickly disappeared on the sea.
The vent pipe is still exposed, and the rumble of the diesel engine seems to be releasing a lullaby.
"Keep at 5 knots and continue sailing." Captain Lei said.
Their goal is to bring all the submarines in this sea area behind them, away from the sea area where the missiles are actually launched, so that they can bring the greatest convenience to the Great Wall 200 activities.
When the missiles over there are launched, they will start strangling them here, huh, just use you to practice your hands and exercise various anti-submarine methods, everyone can't wait!
"Captain, do you report to the superior now?" the radio soldier asked.
Since the successful launch of the Dongfanghong 1 geosynchronous communications satellite a few months ago, the Navy’s communications have also been easy. Otherwise, long-distance communications would be a problem when the submarine is far away from the land. Now, just use the satellite. Up.
"No, I'll be stunned. Let's communicate during the daily talk time." Captain Lei said, his gaze is on the chart in front of him. Since the other party has followed up, just take him on the bottom of the sea. play for fun?
