The brain was running rapidly, thinking about why the commander of the submarine dared to order the work of the nuclear reactor to be stopped, and soon, Xia Yu guessed whether it was because it was discovered by a Chinese submarine or ship, so he had to stop the work of the reactor, because the noise emitted by the nuclear reactor at full power operation is much higher than that of a conventional submarine propelled by electricity, so the nuclear reactor can only be turned off to improve the concealment effect?

Maybe there is also the reason for active sonar, Xia Yu thought to himself, and then felt that it should be the work of active sonar that made the commander of this submarine feel threatened, otherwise it would be possible to let the nuclear reactor run at the minimum power, instead of shutting down the nuclear reactor, after all, if the nuclear reactor is turned off, the danger is too great.

However, as soon as the nuclear reactor is turned off, the nuclear submarine that uses the backup power supply will remove some unimportant equipment, so as not to cause a waste of electricity, if necessary, the active sonar system is naturally among them, Xia Yu, who thought of this, immediately left the control room, and now it is no longer necessary to continue to stay in the control room, because the systems that are still in operation are very important equipment, once damaged, no one knows what the consequences will be, Xia Yu can only leave the control room, and come directly to the monitoring console where the leaves are.

Xia Yu, who had just arrived at Ye Zi's side, had not had time to say a few words before he noticed the abnormal vibration and sound, which was the sound made when the torpedo compartment was filled with water. The submarine was about to attack, and Xia Yu, who realized this, asked Ye Zi to hold on to his seat, and at the same time sat on the seat next to him to fix himself.

No matter who this submarine is planning to attack, the submarine itself that has entered the combat state is unstable, and an emergency sinking or floating may injure the unprepared crew, these things are all learned by Xia Yu when he participated in the outward bound training, at this time, all these knowledge were used, and Xia Yu couldn't help but secretly rejoice in the outward bound training plan he proposed at the beginning.

Naturally, the sound of the US nuclear submarine's torpedo bay filling reached the two searching Navy ships, and almost at the same time, the sonars on both ships shouted in unison, making everyone's nerves tense.

"Sink 50 meters, and push the left full rudder at full speed." The captain of the 039A submarine immediately gave the order, and at the same time, the bearded captain of the nuclear submarine also gave the order: "Launch tube No. 1, launch." Launch tube No. 2, launch. ”

Quietly underwater, with the opening of the torpedo hatch, two torpedoes dragged the wire out of the torpedo tube, and the screen of the sonar display console of the nuclear submarine showed a high pulse spike with the launch of the torpedo.

"Torpedo out of the tube!" Almost at the same time, the sonar crews of the 139 ship and the Type 039A submarine immediately discovered the torpedo launched by the nuclear submarine, and directly reported the course and speed of the torpedo loudly, and the commanders of the two ships also reacted immediately and made an emergency evasion, and at the same time fired air curtain shells and decoy bombs to interfere with the torpedo, but the wire-guided torpedo can be controlled by the launch boat all the time, so it is not so light that it can be gotten rid of, so it is still chasing the two ships.

It is only the responsibility of the Supreme Commander to direct the ship to escape, and his crew can not do much more than follow orders, and the sonar can only report all the information they have monitored under the flashing red attack warning light.

"1900 meters, 1800 meters......" said this recurringly, and the sonar man shouted hoarsely.

"Right full rudder, full throttle, launch anti-torpedo torpedoes." The commander shouted.

"Anti-torpedo torpedo launches, distances 1500, 1000, 500, 300, 200, 100. Didn't hit. ”

"Launch decoy bombs and float urgently."

In the sea, which was only a little glimmer and looked very gray, the Type 039A submarine successively threw several decoy bombs around the submarine, and the decoy bombs immediately began to send out a sonic signal similar to that of the submarine in the water to attract torpedoes, and then immediately began to drain the water at full speed, emptying the water tank, and the submarine quickly rushed to the surface of the water under the greatly increased buoyancy. But the torpedo was obviously not so easy to get rid of, and the torpedo that was biting 039A changed direction and continued to rush towards 039A.

"Distance 300, 250, 200, 150......" The sonar operator truthfully reported the distance, but his voice had become very nervous.

"Prepare for the onslaught!" The captain of 039A shouted, and everyone clung to what was able to hold on to them, ready to accept the torpedo attack.

Modern submarines, no matter how advanced they are designed and how many high-tech countermeasures they have, cannot guarantee that they will be safe and sound after being hit by a torpedo, or that once they are hit head-on by a torpedo, they will sink nine times out of ten. Because submarines are not as good as surface ships, surface ships are hit and damaged, and even if they are hit in a fatal part, there is still reaction time for the crew to escape. But when a submarine in underwater warfare encounters a torpedo attack, there is another fatal thing, and that is water pressure.

Even if the torpedo does not suffer a direct attack from the torpedo, even if it is not fatal to the part, if the torpedo causes substantial damage to the hull of the submarine, such as tearing a crack or something, if the depth of the submarine is too deep at this time, the strong water pressure can even directly crumple the steel submarine into a ball like waste paper, and the possibility of the survival of the crew in the submarine is infinitely close to none in that state.

A sense of powerlessness that may die emerges in the hearts of all the officers and soldiers in the 039A submarine, regardless of courage and faith, this is just a relationship between peacetime and peace, and they have not experienced a front-line life-and-death battle, even if they are afraid, the officers and men still try their best to complete the captain's order, and then hand over everything to reality to answer.

With a bang, a torpedo exploded at a distance of about 80 meters from the submarine, and in the display screen on the sonar display console, the pulse peak was instantly full, but at this moment no one can pay attention to the content above, even the sonar himself is no exception, because with the explosion sound, it is the pressure wave that is 100 times stronger than the torrent and has hit the submarine.

Different from detonating in the air, the destructive force that explosives of the same yield can produce underwater is much smaller in range than on land, because the density of water is more than 800 times greater than that of air, and the resistance is needless to say, any missile or bomb that relies on fragmentation to kill is actually not much of a role underwater, so all underwater explosives basically use shock waves to attack the target, because water is a very good conductor of energy, although the range is small and the duration is short, But the speed of propagation is three to four times faster than on land, and the peak of overpressure can even reach more than two hundred times, which also means that the explosives do not even need to hit directly, as long as they are within the peak range of the pressure wave, there is a chance to damage or even sink the submarine.
