The red lights began to flicker, and within half a minute, all the more than 100 officers and men on the submarine were on combat duty.

When Hua Jianfeng walked into the command center, Le Jiacheng immediately greeted him. "It's been confirmed three times, it's the 'Houston'. We've just circled the rear of the Houston, about twenty-five chains, and it's a great position to attack. ”

"No. 3 torpedo loading and firing data," Hua Jianfeng turned around, and after seeing Lu Chengwen nodded, he said again, "Attack sonar preparation, wire guide mode." ”

The energy of the low-frequency sound waves emitted by the submarine attack sonar is so great that it is capable of transmitting tens of nautical miles in the seawater.

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

As the chief of ordnance reported the azimuth and distance data of the target, Hua Jianfeng immediately said: "Fill the No. 3 torpedo tube with water and open the front cover. ”

"Fill the third torpedo tube with water and open the front cover!" The chief of ordnance passed the command to the torpedo compartment through the intercom in the boat.

The torpedo tubes made a "gurgling" sound when filled with water. When the front cover of the torpedo tube was opened, the sound of metal striking from the mechanical equipment was more noticeable.

"Captain, the target is speeding down!" The sonar shouted loudly.

The atmosphere in the command center suddenly became tense, which indicated that the preparations before the launch of the torpedo had revealed the location of the "Gun Squid", and the sonar personnel on the opposing submarine judged that the "Gun Squid" was about to launch a torpedo.

"Torpedo No. 3 launched. Torpedo No. 4 ready, self-guided mode. ”

"Whoosh". Heavy anti-submarine torpedoes, weighing almost two tons, were pushed out of torpedo tubes by high-pressure currents. Dragged a long trailing tail line towards the "Houston".

Hua Jianfeng also walked to the side of the weapon operation table at this time. Look intently at the image displayed on the screen.

Torpedoes have two guidance modes. One is the wire guide. i.e. through the data line. Controlled torpedo attack targets by submarine fire control computers; The second is the self-guided mode. That is, the torpedo's own ground sonar is used to obtain target information. And it is controlled by a torpedo ground guidance device. Let the torpedo automatically attack the target. The former is mainly used against 9 out of 10 targets. And the probability of success is much higher. The main thing is that submarine ground detection equipment is much more sensitive than torpedo ground detection equipment. It can detect the activity of the target more accurately. Provide torpedoes with more accurate attack information. The latter is mainly used in skirmishes. When the submarine needs to avoid the enemy to fire incoming torpedoes. And at the same time, it is time to fight back to the ground. You can't let the torpedo drag a long wire. Exactly. In online guide mode. Submarines can't do large ranges. Maneuver with high intensity.

Judging by what is displayed on the screen. The "Houston" was like encountering a hornet-like bear. It's going crazy and speeding down. But. Torpedoes are much faster than submarines. And the depth of the attack reached 900 meters. The maximum depth of the "Houston" was only a pitiful 450 meters. The ultimate depth is only 530 meters.

Fifteen seconds countdown to the torpedo hit. "Houston" released three sets of jamming devices in a row. Then turn left at full speed to float up.

It seems that this situation has been taken into account for a long time. Hua Jianfeng smiled faintly. A second order was given for the attack.

With the dull sound of the water, the heavy torpedo in the No. 4 torpedo tube galloped out. The torpedo sailed about eight hundred meters, and the active sonar installed in the nose fairing began to work. After only a dozen seconds, the sonar on the torpedo detected the "Houston" floating at a high-speed turn. Receiving the reflected sound wave signal, the fire control computer on the torpedo automatically compares it with the target characteristic information entered in advance. When the two sets of data matched, the fire control computer gave instructions to the course and depth service equipment of the torpedo, and the torpedo fired at a speed of 55 knots towards the "Houston".

At this time, it can be said that every second is in the race.

The Houston had already been attacked, knowing that the Gun Squid was behind it. While evading the attack, the "Houston" had to make every effort to aim the bow at the "Gun Squid" and then counterattack with torpedoes. 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 not the same.

The three sets of jamming devices launched by the "Houston" were capable of influencing self-guided torpedoes, but it was difficult to have an effect on line-guided torpedoes. Shortly after the first two torpedoes were fired, the first torpedo had already passed through the bubble zone formed by the jamming device and again locked onto the target.

It was also at this time that the "Houston" turned ninety degrees and was trying its best to aim at the "Gun Squid".

"Torpedo No. 3 switched to self-guided mode and cut the wire." Hua Jianfeng didn't intend to give the opponent any chance, "The No. 1 torpedo input the shooting data, and the No. 1 fish ** is injected with water." ”

Five seconds later, the Ordnance Chief personally reported the situation. "Torpedo No. 3 has switched to self-guided mode, and the wire has 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, and the probability of destruction of the submarine by the two torpedoes exceeded 96 percent, and the "Houston" was destined to be sunk.

The problem now is that the "Houston" must be delayed in counterattack and not give the opponent a chance to counterattack. Therefore, the "Gun Squid" must try to stay behind the opponent's butt and, preferably, in the back and bottom of the opponent, driving the opponent into a dead end. If the "Houston" wanted to launch a counterattack, it had to continue to turn at a large angle and continue to accelerate, thus shortening the attack distance of the torpedo and reducing the difficulty of the torpedo's attack. Conversely, if the "Houston" intended to avoid the torpedo, it would have to reduce the steering angle while accelerating, increasing the attack range of the torpedo as much as possible and providing more time for interfering with the torpedo. As soon as the second scenario arises, the third torpedo that is ready on board the "Gun Squid" can immediately come in handy.

Although this is Hua Jianfeng's first real command battle, more than ten years of service experience, three years of experience as a captain, plus two combat patrols and a joint exercise every year, he has accumulated rich combat experience, and also made him a very good attack nuclear submarine captain.

"Captain, the Houston has turned right."

When the sonar chief screams, the information is also displayed on the screen of the weapon operating platform.

The Houston, which had previously turned left, suddenly turned to the right, indicating that the boat had spotted a second torpedo and that the first torpedo was still in hot pursuit. Attacked by two torpedoes, the captain of the "Houston" must have given up his plan to attack the "Gun Squid" and decided to protect himself.

However, under the premise that the torpedo hit rate was as high as 96 percent, could the "Houston" escape?

"First level, one-third of the propulsion power, keeping up with the 'Houston'." After giving the last order, Hua Jianfeng let out a long breath.

For the next two minutes or so, the officers and men on the "Gun Squid" only had to wait patiently.

When the first explosion came, the officers and soldiers in the command center shouted excitedly, and then they all shut up again. Then came the second explosion.

At this moment, all the officers and men on the submarine cheered excitedly.

Both torpedoes hit, and the "Houston" was certain to die.

The "Los Angeles" class nuclear submarine with a large compartment and a single-hull body is probably the most "vulnerable" nuclear submarine in the world. As long as one compartment is flooded, its remaining buoyancy is not enough to float to the surface. On the contrary, the survivability of the Russian Navy's nuclear submarines, which have small compartments and double hulls, is significantly better than that of the Los Angeles class nuclear submarines.

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

Soon after the explosion had subsided, there was a creepy cracking sound of metal. This is the sound of the undamaged pressure-resistant hull of the Houston when it sank and deformed and cracked under the weight of seawater. All the officers and men on board the "Gun Squid" remembered this sound, and it was the first time they heard the sound of the submarine's pressure-resistant hull deforming and rupturing.

Lu Chengwen also had an unprecedented fear in his heart.

When the pressure-resistant shell rupture, more than 100 officers and men on board the "Houston" were crushed by dozens of atmospheres of seawater in an instant. Death came so fast that the deceased didn't even have time to cry out for help. However, isn't the "crunching" sound coming from this time the call of death?

A nuclear submarine of several thousand tons and more than 100 servicemen will forever remain in the mud on the seabed more than 5,000 meters above the surface of the sea.

From beginning to end, the officers and men on the two submarines did not meet each other, and they did not even know what the other side looked like, nor did they know the name, age, or whether they had a family. However, in just a few minutes, more than 100 officers and men aboard the "Gun Squid" became the executioners of more than 100 officers and men aboard the "Houston." When the officers and men on the "Spear Squid" cheered for victory, who would have thought that they had just slaughtered more than a hundred living people with their own hands?

This is war, without the slightest mercy or sympathy.

Hua Jianfeng was also very excited, he didn't stop the cheering officers and soldiers, until the sonar chief suddenly shouted, Hua Jianfeng stood up violently, and the officers and soldiers in the command center immediately shut up.

The thud of the attack sonar, no, is the slapping sound of the torpedo active sonar.

"The first fifteen, the tail ten, the left full rudder, full power propulsion!" Hua Jianfeng gave the order in the first time, "Deputy Chief, calculate the hit time." ”

"Forty-five seconds!"

"Depth?"

"Three hundred and seventy-five meters."

"The front and rear ballast tanks are filled with water and dive at full speed."

By the time Lu Chengwen reacted, the "Gun Squid" had already rushed towards the deep sea at a 25-degree depression angle. At this time, the "torpedo" fired from the rear was already less than 1,500 meters away from the "Gun Squid".
