With the banging sound of deep bomb explosions, in addition to Hua Jianfeng, there was a creepy feeling on the "Swordfish"

"The sea must be very lively." Le Jiacheng squeezed out a smile, trying to ease the tense atmosphere

"Money, deep water bombs are all bought by money!" Hua Jianfeng smiled and shook his head, "It must be Lin Xiaolei's 'prodigal son' who commanded the fleet to fight. Only he is willing to throw deep water bombs around."

Le Jiacheng also shook his head with a smile

After the end of the Fourth India-Pakistan War, the Republic's Navy spent half a year summarizing the experience and lessons of Lin Xiaolei becoming famous in the battle. His "big move" when launching the second round of missile attacks was also controversial. Although the Navy did not deduct Lin Xiaolei's allowance, he gave him the rank of lieutenant general, whether to spend dozens of expensive anti-ship missiles to deal with several warships destined to sink has always been the focus of discussion among naval officers and soldiers.

From then on, the officers and soldiers privately jokingly called Lin Xiaolei the "prodigal son" of the Navy.

"Report, just received the telegram"

Hua Jianfeng was shocked and took the telegram from the communication officer.

"Combat Order?"

Hua Jianfeng nodded and handed the message to Le Jiacheng

The content is simple, only a few: "Plan b"

Le Jiacheng hesitated for a while and went to store the safe in the combat plan and brought a few pages of documents.

Two days ago, the "Swordfish" received an order to float up to the depth of the periscope. It received three combat orders using a satellite communication antenna. Then the "Swordfish" returned to the deep sea and lurked in the northeastern waters of the Diaoyu Islands.

Among the three orders, plan b is the most special

You don't have to look at Hua Jianfeng and you know that the General Staff let the "Swordfish" perform a free hunting mission, but the hunting targets are limited to Japanese submarines.

"Troubleshooting Japanese submarines" Le Jiacheng quickly looked through the documents "Waste broke out?"

"Maybe it's not certain." Hua Jianfeng touched his pocket for a while and found that he forgot his cigarette in his cabin. "If the war has broken out, our top priority is to attack the Japanese Fourth Fleet, of course, it is not ruled out that the General Staff will arrange other forces to deal with the Fourth Fleet and we will deal with the Japanese submarines."

"Maybe it just let us teach a lesson to the Japanese."

Hua Jianfeng nodded and walked to the tactical podium

After large-scale modification, the area of ​​the "Swordfish" command center doubled, and two new monitors were added to the tactical podium. The main monitor increased by 24 inches by 42. The biggest change is that all tactical information can be displayed on three screens for reference by submarine commanders including the captain, deputy captain, and commander of the pilot. In this way, Hua Jianfeng is not the only one who makes the decision.

The battlefield situation displayed on the screen is very clear

The East China Sea Fleet is in the southeast direction, with fourteen warships lined up in a column and sailing at a speed of 16 knots to 290 degrees. The Japanese Fourth Fleet is in the northeast direction, and the queue is very chaotic. The aviation anti-submarine destroyers and two air defense destroyers are in the center of the queue, and the general destroyers are distributed around.

Hua Jianfeng is not afraid of Japanese warships, but is worried about anti-submarine helicopters in the air

The Fourth Fleet is nominally the "Ninety Fleet", but in fact it has 12 places: the "Swordfish" is less than 10 nautical miles away from the Japanese Fourth Fleet. As long as the whereabouts are exposed, the anti-submarine helicopter can arrive within 5 minutes. In this case, the chances of the "Swordfish" successfully evacuated will not exceed 50%.

The complex battlefield environment also makes Hua Jianfeng feel headache

Above the sea, in addition to Japan's anti-submarine helicopters, there are also anti-submarine helicopters of the East China Sea Fleet. Although Japan's anti-submarine helicopters are difficult to perform submarine search and attack submarine missions under the entanglement of our forces, as long as the "Swordfish" launches torpedoes to attack Japanese submarines, the Fourth Fleet will retaliate, use the sonar on the destroyer to find the "Swordfish", and then use rockets to boost the anti-submarine torpedoes, or the aviation anti-submarine torpedoes carried by the helicopter to attack the "Swordfish"

Thinking about a retreat method before starting the battle is the basic tactical idea of ​​every submarine captain

"Using two-level speed and automatic attack mode" Le Jiacheng is also considering this issue, "After launching the torpedo, we will leave the battlefield immediately."

"This kind of attack will not be much more effective"

Hua Jianfeng rubbed his forehead and his eyes fell on the tactical screen again

The situation under the sea is also very complicated. After arriving at the battlefield, with the better performance of the sidewalk passive sonar, the "Swordfish" discovered nine submarines before releasing the towed sonar, including the 2093-class attack nuclear submarine, the 3 AIP conventional submarines of the Republic Navy, and the other four are the "Qiant Tide" class conventional submarines of the Japanese Navy. Several hours ago, the "Swordfish" released the towed sonar and discovered a +95 attack nuclear submarine lurking nearby.

After the East China Sea Fleet encountered the Fourth Japanese Fleet, the Swordfish took back the drag-and-drop sonar

At this time, except for not knowing the whereabouts of the +95 attack nuclear submarine, the other nine submarines have been under the surveillance of the "Swordfish".

Including the "Swordfish" and the 095-095-40 nautical miles, there are a total of 11 submarines!

This is equivalent to throwing 11 crabs into a bathtub. Not to mention attacking, even if you move your lower body, it will be easily discovered by nearby submarines.

Before launching the torpedo, the noise generated by injecting water into the torpedo tube is enough to cause the "Swordfish" to storm.

Fight, or not?

Hua Jianfeng took a long breath and said, "How many days can I drink the beer in the freezer?"

Le Jiacheng hesitated for a moment and said, "If you can't finish drinking for a month, why do you ask me for this?"

"Since you have food and drink, you don't have to rush to start." Hua Jianfeng stretched, "Give everyone a glass of beer, let's wait."

Le Jiacheng hesitated for a moment and ordered the engineer to go to the kitchen to prepare beer

As early as a few years ago, Japan began to build conventional submarines with AIP systems. It is probably too much money to install AIP systems for submarines that have been built and put into service. Japanese submarines use two completely different AIP systems. The newly built "Xichao" class uses oxygen ion membrane fuel cells from Germany, and the modified "Qinchao" class uses "Sterling" closed-circuit diesel engine from Sweden.

AIP system gives conventional submarines strong underwater endurance

However, conventional submarines are always conventional submarines, and their underwater navigation capabilities cannot be compared with nuclear submarines. Even the fully electric submarine of the "Swordfish" is not as good as the hydroxide ion membrane fuel cell or the "Sterling" engine. At most, conventional submarines can submarine underwater for two to three weeks, and their navigation speed is less than 4 times higher.

To submarine at a faster speed, you have to use the battery on the submarine

The conflict broke out on July 10, and Japanese submarines left the port on July 711 and arrived near the Diaoyu Islands from July 14 to 15. During this period, it can be calculated that Japanese submarines must have used batteries. After speeding up the ferry speed to reach the war zone, Japanese submarines will definitely reduce their speed to less than 2 and use the AIP system to charge the battery so that the maximum submarine speed can be achieved in an emergency.

In this case, those Japanese submarines stayed in the war zone for up to 34 days, and then they had to return.

Time has passed, and for Hua Jianfeng, who has been waiting in the war zone for several days, waiting for another 1 to 2 days is not a big problem.

As beer was delivered to every officer and soldier, the atmosphere on the submarine also relaxed a lot.

The sound of a deep-water bomb explosion from outside the boat was much sparse. The tactical screen showed that the East China Sea Fleet completed its second turn and followed the Japanese Fourth Fleet to the southeast.

About an hour and a half later, Hua Jianfeng walked to the tactical podium.

Passive sonar has been monitoring the surrounding situation. As carrier-based helicopters from both sides return to the warships to refuel, the battlefield environment has "improved" a lot.

Hua Jianfeng glanced at his partner, and the Lejia sounded the battle alarm as soon as he was established.

The red lights were on, and the officers and soldiers who had just drunk beer returned to their respective posts.

"Captain, there is something abnormal!"

"See it, keep paying attention!"

On the tactical screen, the light spots representing the Republic's submarine are moving rapidly, and the 3 conventional submarines are approaching the Japanese Fourth Fleet, and the submarine depth has also risen by 40 meters from 240.

Missile attack or torpedo attack?

Hua Jianfeng's brow jumped a few times and asked the conventional submarine to launch an attack first, which was not in line with the basic tactics. In addition, the noise caused by those submarines was too great, which must have aroused the vigilance of nearby Japanese submarines.

What do they want to do?

"Bail!" Le Jiacheng muttered

Hua Jianfeng nodded slightly, it must be that the conventional submarines received the order from the General Staff. The "Swordfish" has not taken action. He believes that the "Swordfish" did not lock in the Japanese submarines. They took the initiative to fight as bait. Perhaps, their mission is to act as bait.

"1, 2, 3 torpedo loading fire control data, primary extremely low speed, line-guided attack mode, locking three Japanese submarines that pose the greatest threat." Hua Jianfeng did not hesitate anymore, and the 4 torpedo adopts full-speed self-guided mode, and the fire control data is not installed for the time being."

"The fire control data has been installed and the attack mode has been set"

Hua Jianfeng nodded and did not immediately issue an order to inject water into the torpedo tube.

"Lao Hua..."

Take a look at the deputy, Hua Jianfeng pressed his hand, signaling Le Jiacheng not to hurry

"Captain, the sound of torpedo tube injection, the speed of Japanese submarine increased by 4, and the depth was 240.

Le Jiacheng clenched his fists and cast an anxious look at Hua Jianfeng. The Japanese submarine discovered the conventional submarines that were ready to attack the Fourth Fleet and were ready to launch an attack.

"Our submarine accelerates to float up, and the Japanese submarine opens the front cover of the torpedo launcher."

"Lao Hua!"

"Inject water from the torpedo tube, prepare to open the front cover." Hua Jianfeng supported his hands on the tactical podium, "Only sailing tube, minimize noise preparation..."

"Japanese submarines launch torpedoes..."

"emission!"

Three heavy electric anti-submarine torpedoes were fired in turn, and at a speed of 35 knots, they were fired at three Japanese "Qiant Tide" class conventional submarines within 5 to 10 nautical miles.

Le Jiacheng pressed the switch on the stopwatch and began to calculate the time when the torpedo hit the Japanese submarine

Hua Jianfeng looked at the tactical screen without turning his eyes

Can those three conventional submarines avoid torpedoes fired by Japanese submarines?

damn it*
