The mother battle group turned north in the early morning of the 5th and approached Jeju Island.

At 3:35 on the 5th, the first batch of long-range anti-submarine patrol aircraft arrived and set up an outer anti-submarine cordon within 00 to 150 kilometers ahead of the aircraft carrier battle group route.

Hua Jianfeng organized the 54 anti-submarine helicopters in the battle group into three anti-submarine brigades, always ensuring that one brigade's 18 anti-submarine helicopters perform patrol missions within 50 to 1c0 meters in front of the battle group, the other brigade prepares for takeoff on the battleship, and the last brigade is maintained in the hangar. The 1c+ anti-submarine warships in the fleet are organized into two anti-submarine patrols, respectively, perform anti-submarine patrols and search missions 25 kilometers in front of the fleet, which is most vulnerable to attack. The towed sonar on the battleship is enough to detect submarines within 50 kilometers. The submarines accompanying the active in a fan-shaped anti-submarine search queue about 200 kilometers in front of the battle group, forming a long-range anti-submarine alert network for the battle group.

It seems that the fleet's anti-submarine network has great loopholes, especially behind the fleet, where there is almost no anti-submarine power.

In fact, the fleet's anti-submarine network is "sparse but not leaking".

Because the South Korean Navy has only a maximum speed of only 20 knots and has very limited submarine capabilities, the navigation speed of the aircraft carrier battle group has always been above 16 knots, so Hua Jianfeng did not consider the threat from the rear. If the Korean submarine dares to pursue the aircraft carrier battle group from the rear, not to mention whether it can catch up, even if it can catch up, it will be discovered by the towed sonar on the warship more than 1 kilometer away due to the huge noise emitted during high-speed navigation. No matter how fast the submarine is, it will not be faster than anti-submarine helicopters and anti-submarine missiles. For conventional submarines, exposure means being sunk!

The threat comes from the front hemisphere of the fleet, most likely to attack the warship's route side with torpedoes.

During the ferry, Hua Jianfeng did not call for "support".

At 7:30 on the 5th, Hua Jianfeng sent a message to the Navy Command, asking the submarines that came to support to go to the combat patrol waters of the aircraft carrier battle group as soon as possible and complete the "cleaning" work before the aircraft carrier battle group arrives.

15 minutes later, the Navy Command issued a new command using an ultra-long-wave radio.

At 7:55, I just passed the Tula Strait and entered the Yellow Sea to float to the depth of the periscope. I was ready to receive the orders sent by the communication satellite.

"Captain. Anti-submarine patrol aircraft is moving away."

"Wait a little longer." Du Xinghua was very stable. "Anyway, there is no hurry to wait for the dog to walk away before stretching out the communication antenna."

Rong Kangjian glanced at his partner and nodded to the communications officer.

At this time, Du Xinghua and Rong Kangjian were most worried about not the Japanese anti-submarine patrol aircraft, but the "unidentified submarine" where they encountered in the Tula Strait. The other party seemed to have noticed the existence of the "Attoria" or smelled the fighting atmosphere. Shortly after the "Attoria" left the Tula Strait, the submarine left the strait along the same course and headed towards Jeju Island at a speed of about 6 knots. Fortunately, the "Attoria" collected characteristic noise and was able to monitor the whereabouts of the other party.

Because the "April" has been sailing at extremely low speeds, Du Xinghua believes that he was not discovered by the other party.

"Captain..."

"Stretch out the communication antenna and move more gently." Du Xinghua glanced at the communication officer and returned to the screen.

The triangle icon representing the submarine appears and disappears, indicating that the signal received by the sonar is very weak.

"It's still 350 meters, 6 knots, and the course has not changed." Rong Kangjian said with a long breath, "It must be a Type 8111 submarine. If it were a conventional submarine from Japan or South Korea, we would have determined its specific model long ago."

Du Xinghua nodded. "You said, is it going to watch the fun or join the battle?"

"It should be to watch the fun." Rong Kangjian smiled bitterly, "Huanghai has always been our territory. No matter how arrogant the Americans are, they must distinguish the home and away game."

"I don't think it's necessarily..."

"Captain, I received the order."

"Retract the periscope, dive to the depth of meter, and re-determine the route.

"Du Xinghua didn't think much about it, knocked on the triangle icon on the screen, and said to his partner, "Try to put the Americans in front and find opportunities to collect more characteristic noise. If the Americans go to watch the fun, we will be guests. If the Americans dare to act rashly, we will treat them with torpedoes."

Rong Kangjian nodded and began to compile navigation data.

The communication officer handed a computer in his palm to Du Xinghua. After looking at the combat order he had just received, Du Xinghua showed a comfortable smile.

The Navy dispatched eight submarines near Jeju Island (including two submarines that were originally accompanied by aircraft carriers).

There are not many more ships, and there are not many less ships.

Du Xinghua is very familiar with the situation near Jeju Island. Even if all 12-regular submarines in the South Korean Navy are deployed, at most submarines are needed to occupy a favorable position to ensure the safety of the aircraft carrier battle group. The Navy sent 8-submarines over and had no intention of increasing the insurance coefficient.

What really reassuring Du Xinghua is that the "River Porpoise" commanded by Liu Haifeng is also among them.

Du Xinghua didn't know other captains, but he knew Liu Haifeng very well.

After Hua Jianfeng left the submarine force, only Liu Haifeng had the strength to challenge Du Xinghua and compete for the "number one ace".

Liu Haifeng is a "replica" of Hua Jianfeng. If it weren't for the fact that it was a few years later"

, I'm afraid it's not the turn of Du Xinghua and Hua Jianzhi who missed several opportunities, even Hua Jianfeng did not have the chance to become the "number one ace". In terms of the ability to command submarines in combat field, Liu Haifeng is no worse than anyone else, both capable and courageous.

With Liu Haifeng "blocking" in front, Du Xinghua decided to do his best to deal with the ignorant American submarine.

Although the Navy will not multiply the tonnage of the US ship by a factor greater than 1 when calculating the results of the battle, the Navy will give priority to the "best" results when measuring the captain of the submarine. Hua Jianfeng's ability to become the director of the "Swordfish" is not unrelated to his sinking of an American submarine in the Indian Ocean. After the East China Sea Battle, Hua Jianfeng's ability to be transferred to the aircraft carrier battle group is also closely related to his sinking of a "Virginia" class submarine during the battle.

Du Xinghua thought clearly that if he could kill the "8111" class submarine, he would be promoted before the age of 50, transferred to a certain aircraft carrier combat group or a certain fleet of submarine brigade to serve as commander, and continued to serve until the age of 65. If he could not be promoted before the age of 50, he would have very little hope of promotion after the age of 50, and he would serve until the age of 55, retire as a naval colonel and end his military career.

For Du Xinghua, who dedicated his youth to submarines, it is not that he does not want to retire, but that he does not want to retire too early.

Three hours later, the main propulsion motor of the "April" stopped working and was pushed by two heading control thrusters. The speed was reduced from below 2 knots and the noise also decreased from below 82 berms.

"The distance is twenty-five chains, the direction of the clock." Rong Kangjian marked the US submarine on the screen, "The computer is recording characteristic noise, and the target navigation data has not changed."

"We should not be discovered." Du Xinghua was also a little nervous, "The thruster relationship will keep everyone quiet."

The two heading propellers stopped quickly, and the officers and soldiers in the boat held their breath.

The noise emitted by the US submarine is very weak and cannot be heard by the human ears. Even the passive sonar can only receive noise signals intermittently.

"The course has not changed, and the speed has not changed." Rong Kangjian breathed a sigh of relief and said, "The Americans did not find us and were still sailing towards Jeju Island.

”

"Stay calm." Du Xinghua glanced at the officers and soldiers in the command center, "Keep the distance above fifty chains and take the z-shaped route at eight-chain speed."

Rong Kangjian nodded, indicating that he understood Du Xinghua's meaning.

Although the submarine ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

For submarines with a displacement of thousands of tons, the speed of several knots is equal to "climbing the turtle".

After about 90 minutes, the 8111 class submarine surpassed the "April".

"The main thruster starts and controls the acceleration." Du Xinghua glanced at the helm's rank, "Be gentle, don't make too much noise. Re-estimate the target route and set sail data."

Even if the "z"-shaped course is taken, the "April" cannot continuously monitor the target and must set the route based on the estimated data.

"I bite it, and the target navigation has not changed."

"Keep the speed and depth." Du Xinghua patted his partner's shoulder, "Import me immediately if there is any situation, and I will change shifts in four hours."

"No problem." Rong Kangjian looked at his watch, "I'll wake you up during dinner."

Du Xinghua smiled and left the command center.

At this time, the "River Porpoise" was sailing towards the combat waters at a speed of 6 knots.

After the outbreak of the Peninsula War, the "River Porpoise" commanded by Liu Haifeng has been operating in the western waters of the Jeju Strait in the Yellow Sea, monitoring Korean submarines entering the Yellow Sea through the Jeju Strait. After one day, Liu Haifeng completed the mission very well, and discovered at least 7 conventional Korean submarines and issued a timely alarm, allowing the Navy to send other submarines or anti-submarine patrol aircraft to monitor the whereabouts of Korean submarines.

In the afternoon, the "Eighth" Korean submarine was discovered by the "River Porpoise".

After contacting, Liu Haifeng concluded that it was a German-made 2211 AIP conventional submarine.

While he was about to give up his tracking and continue to search for other Korean submarines, the Navy Command sent a combat order.

Liu Haifeng was not late and immediately commanded the "River Porpoise" to catch up with the 2211 ship.

On the morning of the 5th, the "River Porpoise" discovered another 2~ Korean submarines, one 2211 and one "Tiger Shark" (a conventional AIP submarine developed by France after the "Scorpio" class). By the afternoon of the 5th, it was also when the "Spirit Porpoise" bit the "8111" ground, the passive sonar of the "River Porpoise" detected 6 Korean submarines, 3~2211 and 3 "Tiger Sharks".

An "underwater fleet"!

Liu Haifeng was very excited because they were the result of 6 battles delivered to the door!
