The red light began to flash, and within half a minute, more than a hundred officers and soldiers on the submarine all entered the combat post.

When Hua Jianfeng walked into the command center, Le Jiaxing immediately came up. "It has been confirmed three times that it is the 'Houston'. We just walked around the rear of the 'Houston', about twenty-five chains, and an excellent attack position."

"The No. 3 Torpedo reloads the shooting data," Hua Jianfeng turned around, and nodded when he saw Lu Chengwen, and then said, "Attack sonar preparation, line guide mode."

The energy of the low-frequency sound waves emitted by the submarine attacks the sonar is very huge and can pass through dozens of nautical miles in sea water.

"The direction is three or five, the distance is two or six!"

As the Ordnance Chief reported the target's position and distance data, Hua Jianfeng immediately said: "Inject water from the No. 3 torpedo launch tube, open the front cover."

"Inject water from the No. 3 torpedo launch tube, open the front cover!" The ordnance commander passed the order to the torpedo compartment through the telephone in the boat.

When the torpedo launcher is injected with water, it makes a "gurgling" sound. When the front cover of the torpedo launcher is opened, the metal impact sound from the mechanical equipment is even more obvious.

"Captain, the target accelerates the dive!" The sonar shouted out loud.

The atmosphere in the command center suddenly became tense, which indicated that the preparations before launching the torpedo had exposed the location of the Calamari, and the sonar on the opponent's submarine determined that the Calamari was about to launch the torpedo.

"Torpedo No. 3 is launched. Torpedo No. 4 is prepared, self-guided mode."

With a "swoosh", a heavy anti-submarine torpedo with a weight of nearly two tons was pushed out of the torpedo launch tube by high-pressure water flow. He dragged the long guide tail line toward the "Houston".

Hua Jianfeng also walked to the weapon operating platform at this time and looked at the ground image displayed on the screen.

There are two guidance modes for torpedoes. One is line guidance, that is, through data lines, the torpedo attacks the target by the submarine fire control computer; the other is self-guided mode, that is, using the torpedo's own ground sonar to obtain target information, and the torpedo ground guidance device is used to allow the torpedo to automatically attack the target. The former is mainly used to deal with a certain target. The probability of the attack success is much higher. The main reason is that the ground detection equipment on the submarine is much more sensitive than the ground detection equipment on the torpedo. It can more accurately detect the activity of the target and provide more accurate attack information for the torpedo. The latter is mainly used in encounter battles. When the submarine needs to avoid the enemy's torpedo shooting in the ground and counterattack at the same time, the torpedo cannot drag long ground conductors. That's right. In the online guide mode, the submarine cannot perform large-scale and high-intensity ground maneuvering.

Judging from the ground displayed on the screen, the Houston was like a hornet bear. It was accelerating its dive in a crazy manner. However, the torpedo ground speed was much faster than the submarine. The attack depth reached 900 meters. The maximum dive depth of the Houston ground was only pitifully 450 meters. The extreme dive depth was only 530 meters.

When the torpedo hit countdown fifteen seconds, the Houston released three sets of jamming devices in a row. Then he turned left and floated up at full speed.

It seemed that this situation had been considered long ago. Hua Jianfeng smiled faintly and issued a second attack order.

Amid the dull sound of water flow, the heavy torpedo in the No. 4 torpedo launch tube galloped out. The torpedo sailed about 800 meters, and the active sonar installed in the first fairing began to work. After just ten seconds, the sonar on the torpedo detected the "Houston" floating on a high-speed turn. After receiving the reflected sound wave signal, the fire control computer on the torpedo automatically compared it with the target feature information input in advance. When the two sets of data coincided, the fire control computer issued instructions to the heading and depth service equipment of the torpedo, and the torpedo shot towards the "Houston" at a speed of fifty-five knots.

At this time, it can be said that it is racing against time.

The Houston has been attacked and knows that the Calamari is behind it. While avoiding the attack, the Houston must do everything possible to aim the bow of the Calamari and then counterattack with a torpedo. Therefore, to ensure absolute safety, it is necessary to sink the Houston before it can launch a counterattack.

Submarine warfare is similar to combat air combat, but it is also different.

The three groups of jamming devices launched by the Houston can have an impact on self-guided torpedoes, but it is difficult to act on line-guided torpedoes. Shortly after the second torpedo was shot out, the first torpedo had passed through the bubble zone formed by the jamming device and locked the target again.

At this moment, the Houston turned ninety degrees and was trying its best to target the Calamari.

"The No. 3 torpedo turned into self-guided mode and cut off the wires." Hua Jianfeng did not intend to give his opponent any chance. "The No. 1 torpedo inputs shooting data, and the No. 1 fish** injects water."

Five seconds later, the Ordnance Chief personally reported the situation. "The No. 3 torpedo changed to self-guided mode and the wires have been cut."

"Fifteen on the head, ten on the tail, two-thirds of the propulsion power, one-third of the left rudder."

Hua Jianfeng did not rush to shoot the third torpedo. The probability of the two torpedo destroying the submarine exceeded 96%, and the "Houston" was destined to be sunk.

The problem now is that the counterattack time of the Houston must be delayed and the opponent will not be given a chance to counterattack. Therefore, the Calamari must try to stay behind the opponent's butt, and it is best to be behind the opponent's back and below to force the opponent to death. If the Houston wants to launch a counterattack, it must continue to turn at a high angle and continue to accelerate, thereby shortening the attack distance of the torpedo and reducing the difficulty of the torpedo attack. On the contrary, if the Houston intends to avoid the torpedo, it must reduce the steering angle while accelerating, increase the attack range of the torpedoes as much as possible, and provide more time for interfering with the torpedoes. As long as the second situation occurs, the third torpedo ready on the Calamari can come in handy immediately.

Although this is the first time Hua Jianfeng is commanding a real gun, his ten-year service experience, three years of captain experience, plus the second combat patrol and a joint exercise each year, he has accumulated rich combat experience and has also made him a very excellent captain of the attack nuclear submarine.

"Captain, the 'Houston' turned right."

When the sonar screamed, the information was also displayed on the screen of the weapon operation platform.

The "Houston" who turned left before suddenly turned right indicates that the boat had discovered the second torpedo and the first torpedo was still chasing. Attacked by two torpedoes, the captain of the "Houston" must have given up his plan to attack the "Calachite" and decided to protect himself.

But, with the torpedo hit rate as high as 96%, can the Houston escape?

"The first level, one-third of the propulsion power, keep up with the 'Houston'." After giving the last order, Hua Jianfeng breathed a long sigh.

In the next two minutes, the officers and soldiers on the Calamari only needed to wait patiently.

When the first explosion came, the officers and soldiers in the command center screamed excitedly, and then closed their mouths again. Then, the second explosion was the same.

Now, all the officers and soldiers on the submarine cheered excitedly.

If both torpedoes hit, the Houston will surely die.

Using the large sub-member cabin, the single-hull "Los Angeles" class nuclear submarine may be regarded as the most "frail" nuclear submarine in the world. As long as one cabin enters water, the remaining buoyancy is not enough to make it float on the surface of the Shanghai area. On the contrary, the Russian Navy's nuclear submarines that use small sub-member cabins and double-hulls have significantly better survivability than the "Los Angeles" class nuclear submarines.

Not to mention two heavy anti-submarine torpedoes, even one light anti-submarine torpedo can kill the "Houston".

Shortly after the explosion dissipated, a creepy metal breaking sound came. This was the sound of the undamaged pressure-resistant shell deforming and rupturing under the heavy pressure of seawater when the Houston sank. All the officers and soldiers on the Calamari remembered this sound, and this was also the first time they heard the sound of the submarine pressure-resistant shell deforming and rupturing.

Lu Chengwen also felt an unprecedented fear in his heart.

When the pressure-resistant shell ruptured, more than 100 officers and soldiers on the Houston were crushed by dozens of atmospheric pressures in an instant. Death came very quickly, so fast that the dead didn't even have time to make a cry for help. However, wasn't the "crunch" sound coming at this time a call to death?

A nuclear submarine of thousands of tons and more than one hundred soldiers will remain in the seabed silt more than 5,000 meters above the sea surface forever.

From beginning to end, neither officers and soldiers on the two submarines met, and they didn't even know what the other person looked like, or whether they were married. However, in just a few minutes, more than 100 officers and soldiers on the Calamari became the executioners of more than 100 officers and soldiers on the Houston. When the officers and soldiers on the Calamari cheered for victory, who would have thought that they had just slaughtered more than 100 living people with their own hands?

This is war, without any mercy or sympathy.

Hua Jianfeng was also very excited. He did not stop the cheering officers and soldiers. It was not until the sonar suddenly screamed that Hua Jianfeng stood up suddenly, and the officers and soldiers in the command center immediately closed their mouths.

The slamming sound of attacking sonar, no, is the slamming sound of torpedo active sonar.

"Fifteenth head, tenth head, left rudder, full power propulsion!" Hua Jianfeng issued an order immediately, "Deputy Chief, calculate the hit time."

"Forty-five seconds!"

"depth?"

"Three hundred and seventy-five meters."

"Fill water in front and rear auxiliary ballast tanks and dive at full speed."

When Lu Chengwen reacted, the "Calachian" had rushed towards the deep sea at a descent angle of twenty-five degrees. At this time, the "torpedo" shot from behind was less than 1,500 meters away from the "Calachian".
