In the early morning of the 5th, the mother battle group turned north and approached Jeju Island. 【No pop-up novel network】『bubble book』

At 3:35 on the 5th, the first batch of long-range anti-submarine patrol aircraft arrived, and a peripheral anti-submarine cordon was set up within 00 to 150 kilometers in front of the aircraft carrier battle group's route.

Hua Jianfeng organized the 54 anti-submarine helicopters in the battle group into three anti-submarine groups, and always ensured that the 18 anti-submarine helicopters of one group carried out patrol tasks within 50 to 1C0 meters in front of the battle group, and the other one group prepared for take-off on the battleship, and the last one group was maintained in the hangar. The 1C anti-submarine warfare ships in the fleet are organized into two anti-submarine patrol teams, which carry out anti-submarine patrol and search missions 25 kilometers diagonally in front of the most vulnerable fleet. Using the towed sonar on the battleship, it is enough to detect submarines within 50 kilometers. The submarines accompanying the activity advanced in a fan-shaped anti-submarine search queue about 200 kilometers in front of the battle group, forming a long-range anti-submarine warning network of the battle group.

It seems that there are big holes in the anti-submarine net of the fleet, especially in the rear of the fleet, where there is almost no anti-submarine power.

In fact, the anti-submarine network of the fleet is "negligent but not leaky".

Because the ROK Navy only has AIP conventional submarines with a maximum speed of only 20 knots and very limited submarine capability, and the sailing speed of the aircraft carrier battle group has been maintained at more than 16 knots, Hua Jianfeng did not consider the threat from the rear. If a South Korean submarine dares to pursue the aircraft carrier battle group from the rear, not to mention whether it can catch up for the time being, even if it can catch up, it will be towed by the battleship from a distance of more than 1 kilometer because of the loud noise made during high-speed sailing. No matter how fast the submarine is, it cannot be faster than an anti-submarine helicopter or an anti-submarine missile. For conventional submarines, exposure means sinking!

The threat came from the front hemisphere of the fleet, most likely by attacking the battleship with torpedoes on the front of the course side.

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

At 7:30 a.m. on the 5th, Hua Jianfeng sent a message to the Navy Command, asking the submarines that rushed to support them to go to the combat patrol area of the aircraft carrier battle group as soon as possible and complete the "clean-up" work before the aircraft carrier battle group arrived.

Fifteen minutes later, the command of the Navy issued a new command with an ultra-longwave radio.

7:55. Just passed through the Tura Strait. Enter the Yellow Sea and float to periscope depth. Prepare to receive combat orders from communications satellites.

"Captain. Anti-submarine patrol aircraft are moving away. ”

"Wait." Du Xinghua is very stable. "Anyway, it's not in a hurry. Wait for the dog to go away before extending the communication antenna. ”

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

At this time, Du Xinghua and Rong Kangjian were most worried about not the Japanese anti-submarine patrol plane. Rather, it was the "unidentified submarine" that encountered in the Tura Strait. The other party seems to be aware of the existence of the "Thorn Dolphin". Or smell the breath of battle. Shortly after the "Thornfish" left the Togara Strait. The submarine left the strait in the same direction. Drive at a speed of about 6 knots towards Jeju Island. Thankfully, the Thorn Dolphin was able to pick up the characteristic noise. can always monitor the whereabouts of the other party.

Because the "Thornfish" has been sailing at extremely low speeds. So Du Xinghua believes that he was not shown by the other party.

"Captain......

"Stretch out the communication antenna and move gently." Du Xinghua glanced at the communications officer, and his gaze returned to the screen.

The triangular icon representing the submarine appears and disappears, indicating that the sonar is receiving a very weak signal.

"It's still 350 meters, 6 knots, and the course hasn't changed." Rong Kangjian let out a long breath and said, "It must be the Type 8111 submarine, if it is a conventional submarine from Japan or South Korea, we have already determined its specific model." ”

Du Xinghua nodded. "You say, is it going to see the excitement, or is it going to go to the battle?"

"I guess I'm going to see the excitement." Rong Kangjian smiled bitterly, "The Yellow Sea has always been our territory, and no matter how arrogant the Yankees are, they can also clear the home and away games." ”

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

"Captain, orders received."

"Retract the periscope, dive to a depth of meters, and re-determine the course." Du Xinghua didn't think much about it, tapped the triangle icon on the screen, and said to his partner, "Try to put the Yankees in front and find an opportunity to collect more characteristic noise." If the Yankees go to see the excitement, we will be the guests. If the Yankees dare to act rashly, we will treat them with torpedoes. ”

Rong Kangjian nodded and began to compile the voyage data.

The communications officer handed Du Xinghua a handheld computer. Glancing at the combat order he had just received, Du Xinghua showed a pleasant smile.

The Navy dispatched 8 submarines to the vicinity of Jeju Island, including 2 submarines that had previously accompanied the activities of the aircraft carrier.

One more is not much, one less is not less.

Du Xinghua is very familiar with the situation near Jeju Island, and even if all the ROK Navy's 12 conventional submarines are dispatched, the most submarines are needed to occupy an advantageous position and ensure the safety of the aircraft carrier battle group. The Navy sent 8 submarines over, not intending to increase the insurance factor.

What really reassured Du Xinghua was that the "Finless Porpoise" commanded by Liu Haifeng was 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 trump card".

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

, missed several opportunities, I'm afraid it won't be Du Xinghua and Hua Jianzhi's turn at all, and even Hua Jianfeng has no chance to become the "number one trump card". In terms of the ability to command submarines on the battlefield, Liu Haifeng is no worse than anyone else, that is, he has the ability and courage.

With Liu Haifeng "in the way" in front, Du Xinghua decided to go all out to clean up the American submarine that was not known to the sky.

Although the Navy does not multiply the tonnage of U.S. ships by a factor greater than 1 when calculating the results, it prioritizes the "best" results when measuring the capabilities of submarine captains. Hua Jianfeng's ability to become the director of the "Swordfish" is not unrelated to the fact that he sank a US submarine in the Indian Ocean in the first place. After the Battle of the East China Sea, Hua Jianfeng was able to transfer to the aircraft carrier battle group, which also had a lot to do with his sinking of 1 "Virginia"-class submarine in the battle.

Du Xinghua thought very clearly: If he could get rid of the "8111" class submarine, he would be promoted before the age of 50 and transferred to a certain aircraft carrier battle group or a certain fleet submarine group as the commander, and continue to serve until the age of 65. If you can't get promoted before the age of 50, you have very little hope of getting promoted after the age of 50, and you can serve until the age of 55 at most, and retire as a colonel in the navy, ending your military career.

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

Three hours later, the main propulsion motor of the "Thornfish" stopped working, and was propelled by two heading control thrusters, reducing the speed to less than 2 knots and the noise to less than 82 belongels.

"Twenty-five chains away, bell direction." Rong Kangjian marked the US submarine on the screen, "The computer is recording the characteristic noise, and the target navigation data has not changed." ”

"We shouldn't be there." Du Xinghua was also a little nervous, "The propellers are all related, let everyone be quiet." ”

The two heading thrusters quickly stopped, and the officers and men in the boat held their breath.

The noise from the US submarine is so weak that it cannot be heard by the human ear, and even the passive sonar can only receive the noise signal intermittently.

"The course has not changed, and the speed has not changed." Rong Kangjian let out a long breath and said, "The Yankees did not show us and still sailed in the direction of Jeju Island. ”

"Hold your breath." Du Xinghua glanced at the officers and soldiers in the command center, "Keep the distance above 50 chains, and take a Z-shaped route at a speed of eight knots." ”

Rong Kangjian nodded, indicating that he understood what Du Xinghua meant.

Although submarine terrestrial sonar can operate in a passive manner, its positioning and ranging performance is far superior to that of a broadside passive sonar. In order to continuously monitor the target, the submarine should try to aim the side side at the target, rather than aiming the boat at the target. Only when attacking, will the bow be aimed at the target. Because it is difficult for a submarine to detect a target behind it, it is possible to increase the sailing speed appropriately when tracking an enemy ship.

For a submarine with a displacement of several thousand tons, the speed of a few knots is equal to a "turtle crawl".

It took about 90 minutes for the "8111" class submarine to overtake the "Thornfish".

"The main thruster is activated, and the acceleration is controlled." Du Xinghua glanced at the non-commissioned officer at the helm, "Be gentle, don't make too much noise." Re-estimate the target route and set the voyage data. ”

Even if it takes a "Z" course, the "Thornfish" cannot continuously monitor the target, and must set its course based on the estimated data.

"Biting it, the distance is fifty-five chains, and the target navigation situation has not changed."

"Keep up the speed and the depth." Du Xinghua patted his partner on the shoulder, "Notify me immediately if there is any situation, and I will come to change shifts in four hours." ”

"No problem." Rong Kangjian glanced at his watch, "I'll wake you up when you're having dinner." ”

Du Xinghua smiled and left the command center.

At this time, in the direction of Jeju Island, the "Finless Porpoise" was sailing towards the operational sea area at a speed of 6 knots.

After the outbreak of the Korean War, the "Finless Porpoise" commanded by Liu Haifeng has been operating in the western waters of the Jeju Strait in the Yellow Sea, monitoring South Korean submarines entering the Yellow Sea through the Jeju Strait. In the first day, Liu Haifeng completed the task very well, and successively appeared at least seven South Korean conventional submarines, and issued an alarm in time, so that the navy could send other submarines or anti-submarine patrol aircraft to monitor the whereabouts of South Korean submarines.

In the afternoon, the "eighth" South Korean submarine appeared on the "Finless Porpoise".

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

Just as he was about to abandon the pursuit and continue the search for other South Korean submarines, the Navy command came to give combat orders.

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

On the morning of the 5th, the "Finless Porpoise" appeared two more South Korean submarines, namely one 2211 and one "Tiger Shark" AIP conventional submarine launched by France after the "Scorpio" class. By the afternoon of the 5th, when the "Thorn Dolphin" bit the "8111" ground, the passive sonar of the "Finless Porpoise" detected 6 South Korean submarines, 32211 and 3 "Tiger Sharks".

An "underwater fleet"!

Liu Haifeng was very excited, because it was the result of 6 deliveries to the door!

It's the last few days of the month, and I'm going to keep the top six monthly passes, so I beg the brothers
