Go read it and watch the latest chapter to the sound of the torpedo entering the water, Rong Kangjian picked up the stopwatch. [No pop-up novel network]

After a while, there was a low slapping sound when the torpedo actively attacked the sonar to search for the target, Rong Kangjian wiped the sweat from his forehead and looked at Du Xinghua, who was sitting in the commander's position and as steady as Mount Tai.

Du Xinghua glanced at the officers and non-commissioned officers in the command center, and there was no nervousness in his expression.

In the past 20 years, Du Xinghua has worked in the position of captain of the Navy submarine for 20 years. The cadets of his contemporaries and submarine captains who served in the army at the same time were either promoted to more senior commanders like Hua Jianfeng, or transferred to the non-combat department and waited for retirement after the service period, or received severance pay from the Navy and retired early.

Up to now, only Du Xinghua is still directing submarine operations on the front line.

In terms of qualifications, Du Xinghua must be the "boss" among the submarine captains of the Republic Navy.

In June 2025, after the end of the Korean Peninsula War, Hua Jianfeng found Du Xinghua and proposed to let Du Xinghua go to the Submarine Academy as a senior instructor, and also hinted that Du Xinghua would have the opportunity to become the president of the Submarine Academy as long as he worked for a few years (according to the establishment system of the Republican Academy, the president of the Submarine Academy is at least a rear admiral. Du Xinghua was also tempted, and at the end of the year, he took the opportunity of family leave to return to his alma mater for an inspection. In the end, Du Xinghua still refused Hua Jianfeng's invitation. In Du Xinghua's words, he has lived on a submarine all his life and is not very accustomed to returning to the shore. Hua Jianfeng didn't force it, but just promised that the position of the Submarine Academy would always be reserved for him and could be transferred at any time.

Is Du Xinghua really used to living on a submarine? Apparently impossible.

Those who know Du Xinghua know that he doesn't want to go ashore, but he just doesn't want to borrow the light of Hua Jianfeng.

For decades, Hua Jianfeng has been Du Xinghua's most important friend and Du Xinghua's most powerful competitor. Although Hua Jianfeng has left the front-line combat unit, no one can deny Hua Jianfeng's status in the submarine force of the Republic Navy. Du Xinghua is not the kind of person who is competitive, but he is also a very face-saving person. If Lin Xiaolei proposed it, Du Xinghua would definitely agree. It's just that everyone knows that Lin Xiaolei is a person who is not good at figuring out other people's thoughts.

Duchende's decision. It also had a great impact on Liu Haifeng.

According to Hua Jianfeng's intentions. If Du Xinghua refuses to go to the Submarine Academy, let Liu Haifeng go to the Submarine Academy. After all, a submarine captain with rich combat experience is needed to teach submarine academy recruits. In accordance with the plan for the development of the Navy. The Submarine Academy was involved in the development and design of the new submarine and needed experienced captains to help the designers. As a result, Du Xinghua did not go. Liu Haifeng also refused to go. The reason is simple. Lost to Hua Jianfeng. Liu Haifeng also recognized it. After all, it was Hua Jianfeng who brought him into the industry at the beginning. If you lose to Du Xinghua. He wasn't convinced.

"Lao Du!"

Du Xinghua's eyebrows jumped a few times. He looked over to his partner.

"The torpedo is approaching!"

"I know." Du Xinghua asked with a long sigh. "Hit the time."

Rong Kangjian hesitated for a moment and said, "Fifteen seconds." ”

Because the anti-submarine torpedo launched by the Japanese anti-submarine patrol plane had not yet found the "Thorn Dolphin," Du Xinghua asked when the torpedo launched by the "Thorn Dolphin" hit the "Canglong."

Du Xinghua stood up and glanced at the main display of the fire control platform in the center.

In addition to showing the trajectory of the torpedo and the "Soryu", the countdown to the torpedo hitting the "Soryu" is also displayed in the upper right corner.

"Captain, continuous slapping, torpedoes are turning towards us."

Du Xinghua frowned slightly, quickly glanced at the upper right corner of the screen, and said: "The left is full of rudders, the speed is 8 knots, and the depth is maintained." ”

Rong Kangjian was stunned for a moment and did not interfere with the captain's command work.

Although Du Xinghua's circumvention order was somewhat unexpected, Rong Kangjian believed that Du Xinghua would be able to lead the "Thornfish" back to port safely. Over the years, Du Xinghua has never made mistakes in patrols and combat operations, and has never disappointed his brothers on the boat.

"Captain, we've been discovered!"

"Know the speed, heading and depth of the vessel."

At this point, the reading in the upper right corner of the screen is just zero.

Du Xinghua muttered something silently and glanced around. "Decoy Bomb Preparation ......"

"Decoy bombs are ready!" The electronic warfare officer immediately replied.

Du Xinghua nodded at the electronic warfare officer, silently read a few times, and suddenly said, "Launch a decoy bomb!" ”

The electronic officer did not dare to delay and immediately pressed the switch to fire decoy bombs.

The decoy bomb had just popped out of the launch tube in the lower right of the submarine's command platform when a dull sound came. It is not the slapping sound of the torpedo attack sonar, but the sound of the torpedo battle mine head exploding in the seawater.

"The main engine stops, the first fifteen, the last fifteen, and slowly dives."

"Dive slowly!" Rong Kangjian patted the helmsman on the shoulder.

Du Xinghua smiled coldly and said, "Now it depends on whether *** is willing to spend money on us." ”

At this time, the officers and men on the boat understood Du Xinghua's evasion attempt.

At the beginning of the year, the Military Intelligence Bureau obtained the performance data of Japan's new aviation anti-submarine torpedoes, which clearly mentioned that Japan's new torpedoes adopted a "dual-mode guidance mechanism." When attacking a submarine, the general anti-submarine torpedo will search in a passive way, and after discovering the submarine, it will switch to an active way to track and lock the submarine until the submarine is sunk. Japan's new anti-submarine torpedoes are active and passive dual-mode guidance for both search and attack, that is, they are used at the same time and mounted on the torpedo head

Attack sonar and passive sonar base arrays mounted on the side of torpedoes search and attack to maximize attack efficiency and reduce the chance of interference.

It seems that the new Japanese torpedo is very advanced, but it is not.

With technical strength, the United States, the Republic, and countries in Europe, such as France and Italy, are capable of using similar guidance methods on anti-submarine torpedoes. These countries did not do this for the simple reason that they worked in both active and passive ways, which not only increased the difficulty of the anti-submarine torpedo in processing information, but also made it easy for the anti-submarine torpedo to be interfered with.

The evasion measures adopted by Du Xinghua were simple, using the sound of explosions to interfere with Japanese aviation anti-submarine torpedoes.

Unlike ordinary sounds, explosions are very complex and cover a very wide frequency band. Regardless of the frequency band in which the passive sonar of the Japanese aviation anti-submarine torpedo operates, it is vulnerable to interference from the sound of explosions. Decoy shells were used to jam the active sonar of the anti-submarine torpedo of Japanese aviation, so that the active sonar and the passive sonar lost the target at the same time. In this case, the Japanese aviation anti-submarine torpedo could only search for the submarine in search mode again.

Taking advantage of this opportunity, it was possible for the "Dolphin" to avoid anti-submarine torpedoes.

"Captain, the torpedo is turning and is leaving us."

Hearing the sonar report, Xinghua only smiled faintly, and the officers and non-commissioned officers in the command center breathed a sigh of relief.

"Prepare communication sonar buoys." Du Xinghua looked at his partner, "Send out the news of sinking the 'Canglong' as soon as possible, and let the Navy Command know that we have completed the combat mission." ”

"Now?"

"Be ready, I'll give the order before launch."

Rong Kangjian breathed a sigh of relief. At this time, no matter what the "Thorn" did, it would make a noise and be spotted by the anti-submarine torpedo again. It is common sense that communication buoys should be launched only after reaching a safe sea area.

"Captain, Ray turned again and came towards us."

"Did you spot us?"

"No, searching."

Du Xinghua frowned slightly. "Lao Rong, it's time for the torpedo to enter the water."

Kang Jian hesitated for a moment and said, "There are about ...... left."

Du Xinghua pressed his hand and said: "The right rudder is full, the speed is 8 knots, and the depth is maintained." ”

Aviation anti-submarine torpedoes are all light torpedoes, and Japan has not mastered the production technology of advanced composite batteries, so most of the light torpedoes use ordinary batteries and engines using Otto fuel. In this case, the range of light torpedoes is very limited. According to the information provided by the Military Intelligence Agency, the maximum range of the anti-submarine torpedo of Japanese aviation was only 20 meters, and at the maximum speed it was 0 kilometers.

Because anti-submarine torpedoes use low speed for search and high speed for attack, the range is between 1C and 20 km. Exactly how much depends on how long the torpedo has been at high speed.

If a submarine wants to avoid torpedoes, it is best to get out of the range of torpedoes.

As the minutes passed, the officers and non-commissioned officers in the command center also became anxious.

The anti-submarine torpedo is still searching nearby, and it is possible to find the "Thorn Dolphin" at any time, and it is also possible to attack the "Thorn Dolphin" again at any time.

"Torpedo distance." Du Xinghua broke the silence.

Kilometers are approaching. ”

Du Xinghua nodded slightly, and after about 1 second, he suddenly said: "The main engine is propelled at full power, with a depth of 540 and a course of 180, moving forward at full speed!" ”

"Full speed ahead!" Rong Kangjian grabbed the helmsman's shoulder.

The advantages of the electric propulsion system are apparent, within 5 days, the propulsion motor reaches its maximum speed power, and the speed of the "Thornfish" increases from 8 to 37 knots in just a few seconds, while the most advanced attack nuclear submarines take at least 65 seconds.

"Use emergency power." Du Xinghua glanced at his partner.

"Emergency power?"

Du Xinghua nodded and didn't say anything more.

Rong Kangjian didn't ask any more questions, and nodded at the helmsman.

"Captain, we were torpedoed."

"Decoy bomb preparation."

"Decoy bombs ready."

Du Xinghua let out a sigh and glanced at his watch.

As the torpedoes approached, the "Thornfish" quickly exceeded 37 knots. When the propulsion motor was working at an emergency power of 125% of the rated power, the "Thornfish" was able to reach the maximum speed of knots. This is also the maximum speed that all electric submarines are capable of reaching today, and only when evading an attack can the electric motor work at emergency power for a short time. If you work at emergency power for a long time, no one can guarantee that the motor will not have problems.

Now, all the "Thornfish" needs is speed.

The maximum speed of the torpedo was only 70 knots, and the maximum speed of the "Thornfish" was able to reach knots. With a difference of 30 knots, the torpedo needed to travel about 85 kilometers to catch up with the "Thornfish". The torpedo had already traveled thousands of meters in the water, and if it could not cover 85 kilometers with the remaining power, it would never have to catch up with the "Dolphin".

Du Xinghua's calculations were very accurate.

When the torpedo was about 250 meters away from the "Thornfish", because the power ran out, the self-destruct device was activated, and about 20 kg of high-energy ** war mine head was detonated.

The officers and men of the whole boat breathed a sigh of relief, and Du Xinghua ordered the communications officer to launch the communication buoy.

Just when everyone thought they had escaped, a dull explosion was heard outside the boat again.

Not to mention other officers and soldiers, even Du Xinghua became nervous.
