Thomas received a message from the submarine below. The unknown submarine underwater actually dived to a depth of 500 meters and was sailing at a speed of 32 knots.

At this time, the catapult's fault had been eliminated, and two S-3 anti-submarine aircraft flew away from the deck of the Kitty Eagle one after another.

The s-3 anti-submarine aircraft can have an anti-submarine radius of 500 nautical miles, so if they are willing, they can completely avoid tracking the damn submarine within more than ten hours. The surface ship can also sail at high speed and keep track of the damn submarine. But what can they do if they catch up? As long as the other party stays in the water and stays in the water below 500 meters and doesn't come out, they have no way to deal with it.

Five hundred meters! Thomas could almost tell that although he had not found out the people in the submarine, he could know that it must be a Soviet submarine!

The Soviets always like to create such things, such as large diving depth and high speed. Two years ago, they discovered that a Soviet submarine was sailing underwater at a speed of more than 40 knots. This speed exceeded the speed of all the torpedoes equipped by the US military, which means that even if they fired torpedoes, they could not catch up with each other.

This time, Thomas's face looked very ugly. He knew that if it were during the war, the aircraft carrier under his feet would be very dangerous.

All the formation personnel already knew that the submarine was showing off in a very close place in their formation, and then blatantly fled.

You must not let it go!

The nuclear reactor at the tail is operating at full power and has been sailing for more than three hours.

"Go forward one. Reduce the navigation, sonar room, and detect whether there are dangerous targets around you." Yeruofu gave the order.

During the full-power navigation just now, the noise of the submarine itself was still very high, and the detection distance of the sonar would be greatly reduced. Now, they have arrived a hundred nautical miles away. You can relax a little.

As the submarine soldiers in the cabin operated, the propellers of the huge submarine began to rotate slowly and their speed slowly decreased.

"The other party's submarine began to slow down." Captain Johnson received a report from the sonar room on the Baton Rouge.

"Slow down immediately, reverse at full speed, and be ready to follow the steering at any time. Don't expose us." He ordered immediately.

During these three hours, the Los Angeles-class submarine was following closely behind the unknown submarine without stopping.

Because, the Los Angeles-class submarine obviously made a mistake in the invasion of this unknown submarine. He had to find the thief who invaded their underwater, which was considered to be a save face. Of course, more importantly, this was obviously a new submarine from the Soviet Union, and he had to follow behind. The submarine's water sound characteristics and various performances were recorded. At the same time, he had to follow the military port where the other party was docked, and then the agents determined what this new submarine was.

Therefore, the Baton Rouge broke away from the aircraft carrier formation and carried out a new mission to follow this unknown Soviet submarine.

Another lobby Los Angeles-class submarine, a hundred nautical miles east of the aircraft carrier formation, has received new instructions to take over its mission and protect the underwater safety of the aircraft carrier formation.

During the Cold War, submarines on both sides often carried out such activities underwater, especially Los Angeles-class attack nuclear submarines. They were already familiar with tracking Soviet ballistic missile submarines.

Johnson has always followed the other party, and this is the other party's blind spot.

For a submarine, there is a main sonar in front and a side sonar on both sides, so it is not a good choice to get close from the front or the side, and it will be discovered by the other party at any time.

There is only the back, because all the submarines are huge propellers behind them, so there is no sonar arrangement here. Even if it is arranged, it will be disturbed by the noise of the propeller and nothing can be found.

Therefore, similar to fighter jets, for submarines, there is an absolute blind spot behind them.

The Los Angeles class is also sailing at its maximum speed. In this case, its own noise is also very loud. However, because it follows the k-132, its noise will not be received by the k-132. However, the huge propeller at the tail of the k-132 is always in front of it (or below the front), so it sounds very clear.

This kind of underwater high-speed tracking and racing took more than three hours.

Now, hearing that the other party slowed down, Johnson immediately ordered to slow down to prevent him from rushing to the front of the other party.

They found that there was a reaction time before they slowed down, so Johnson not only made the submarine reduce its power, but the slowdown was not fast enough. The propeller must be reversed so that the maximum deceleration effect can be achieved and accidents can be prevented. This underwater tracking technique is very familiar to every submarine soldier.

Generally speaking, submarines are rarely sailed underwater. For example, although nuclear submarines have a high speed of thirty knots, they usually sail at a cruise speed of about ten to twenty knots, so that they can avoid the exposure of their positions due to noise and avoid various possible failures due to long-term full power operation of the reactor. Therefore, although the Los Angeles-class speed is not fast enough, Johnson did not give up. In this way, after chasing for three hours, the other party finally began to slow down.

This is still a nuclear submarine. If it is a conventional submarine, it will only rely on the electricity carried in its own battery and sail underwater at full speed, it will consume all the electricity in one hour. Therefore, conventional submarines will only start at full speed when they occupy space.

In order to avoid being discovered, and because the distance is too far, the Baton Rouge did not contact the aircraft carrier, which would expose itself to the other party. Now, he is convinced that the Soviet submarine did not discover it.

The sonar soldiers were listening carefully, confirming that there was no movement around them.

"All people pay attention, the left rudder is full." Ye Ruofu gave another order.

For submarines, the tail is a blind spot. If there are pursuers at the tail, it will not be discovered in time. Therefore, there is only one way to turn quickly. In this way, the submarine that follows at the tail will be exposed to the side sonar of its submarine because it cannot turn in time.

With Ye Ruofu's order, the submarine soldiers underwater immediately and consciously grasped the objects around them like conditioning and solidified their bodies.

Then, a huge centrifugal force came, and the submarine more than 10,000 tons had already begun to turn around.

"The opponent is turning left." In the Baton Rouge, the sonar soldiers immediately discovered the opponent's actions.

"Full the left rudder, pay attention, immediately go full rudder and move forward." Johnson ordered.

The Los Angeles-level behind also began to turn, and the underwater tracking was so exciting.

The sonar soldier of k-132 listened carefully to the surrounding movements again and confirmed that no suspicious target was found. Ye Ruofu ordered the right rudder to search again, because the Los Angeles-class submarine was likely to follow him.

However, no target was found.

"Sink up to 100 meters and continue our original course." Yerofu ordered. They needed to enter the Indian Ocean southwest, and then return to their home port after completing this voyage.

"A large ship on the surface was found, which should be a large tanker with no load." said the sonar.

"Follow up." Ye Ruofu immediately thought of a method. Following the tanker was the safest choice. There were a large number of underwater listening equipment arranged by the United States in the several seas they were about to pass through.

Continue to float up to thirty meters, adjust the course, and after continuing to sail for two nautical miles, k-132 followed under a big belly tanker sailing on the sea.

"Report, the sonar signal of the unknown submarine disappeared." On the Los Angeles-class submarine, Johnson heard a news that made him very frustrated.

How is it possible? The sonar signal of the submarine disappeared inexplicably?

After following the submarine for a distance, Johnson felt more and more that they followed a very special submarine this time, and the noise from the other party was very small!

The reason why Johnson's Los Angeles-class submarine discovered this unknown submarine at such a close distance was that the noise of the other party was too small!

For example, when the Los Angeles class is currently on the road, only within five nautical miles can one be fully confident of discovering it when the opponent is sailing at a distance of twenty nautical miles. Even if the opponent is sailing at full speed, he can only be sure to discover the opponent at a distance of twenty nautical miles. Under the vast water, this distance can almost be said to be almost non-existent.

This noise level is almost comparable to that of the Los Angeles class itself. The noise of Soviet submarines has always been very huge, especially the noise of their propellers, which can be found fifty nautical miles away.

When did the Soviet Union actually transform its submarine so silently?

It is precisely this that aroused more interest from Johnson, and it is necessary to find out clearly! Follow up!

But now the other party has disappeared again. Release the drag array sonar and then find the other party?

Johnson asked the sonar soldier: "Where were they when they finally found out that the other party disappeared?"

"It's been rising all the time, and then the signal disappears." The sonar soldier said: "However, when it disappeared, there was an oil tanker on the sea. The noise of the tanker was too loud, covering up the sound of the target. When the tanker passed, the target disappeared."

The tanker on the sea? The other party is rising? Johnson had an idea in his mind. The Soviets were so cunning!

"Rise to fifty meters, we follow the tanker!" said Johnson. (To be continued)
