Chapter 1179 Feelings

All-electric propulsion is naturally very advanced, and the country is in a leading position in this regard, but generally large ships use conventional drives, mainly because the electric propulsion systems required by large warships are too terrifying, and currently no country has too much. OK

Especially super-large warships like aircraft carriers that cost tens of thousands or even more than 100,000 tons.

As for submarines, not to mention all-electric propulsion, it has an extremely powerful mute effect, and has advantages in various aspects such as acceleration performance.

Hearing Jiang Yanhai's words, the soldier at the helm over there immediately asked, "Would you like to shut down the nuclear reactor and use the all-electric propulsion mode?"

"Yes!" Jiang Yanhai agreed with his mouth, but he was surprised in his heart, because the soldier said that directly, which means that the nuclear reactor of the submarine can be shut down at any time... and not only can it be shut down at any time, which means Its battery can be used for an extremely long time.

Nuclear reactors are not like diesel engines. Gasoline engines can be turned off at any time and can be used when they are ignited at any time.

At the dock, if the nuclear reactor of the submarine is shut down and then restarted, it will take about 12 hours, because it needs to gradually raise the nuclear reactor from normal temperature to a high temperature of several hundred degrees Celsius, and this process cannot be too fast all at once, but must be raised slowly.

This is mainly to prevent thermal shock, as if pouring hot water directly into a cold glass.

Moreover, power is needed to turn on the reactor in this way. It is naturally no problem to have shore power at the dock, but batteries are needed in the sea.

In fact, if the reactor is shut down in the sea, it must be a thermal shutdown, that is, although the reactor is stopped, it is still maintained at a relatively high temperature. It can be done within.

However, this thing is basically not shut down at sea, but it can be shut down at will here, because the cooling system of the nuclear reactor is one of the main sources of noise for nuclear submarines.

It is useless to stop many reactors, because the cooling system is still in operation, so naturally this thing will not stop in reality, but it stops here.

This means that the nuclear reactor here is definitely not any kind of nuclear reactor that Jiang Yanhai knows or knows.

Its technology is undoubtedly very advanced. If the reactor can really be turned into a gasoline engine or diesel engine that can be stopped at any time, then this thing has high usability.

"Report the current status of the submarine." Jiang Yanhai issued another order.

"The current speed is 10 knots, the noise decibel is expected to be 80 decibels, which is lower than the background noise of the ocean, and the depth is 625 meters."

"Is the sonar responding?"

"Report, no, no enemy's voiceprint features have been detected, and the current computer-locked voiceprint features are all natural creatures."

At this time, submarines naturally use passive sonar, and it is impossible to use active sonar. Active sonar is equivalent to exposing themselves. They don't even know where the enemy is, so it is naturally impossible to use active sonar at this time.

"Understood." Jiang Yanhai nodded, and he found another good thing. There is a huge natural biological voiceprint library in this submarine. Although this voiceprint library may not be the same as the real underwater creatures, these data are good. something.

To be honest, Jiang Yanhai has no research on the combat tactics of submarines. He is purely rushing ducks to put them on the shelves. However, things like combat are sometimes the same. Regardless of other weapons and equipment, you only need to consider why the opponent does this. .

In such a state, if the enemy finds them, they must come to arrest them.

Submarine warfare is sometimes more than patience, and the enemy may not have discovered them.

"Dive slowly to the limit depth." Jiang Yanhai thought for a while, and then gave another order.

"Yes!" The helmsman here immediately began to operate.

"The submarine is diving, the current depth is 630 meters... 631 meters..."

The depth of the whole submarine was constantly increasing. Jiang Yanhai didn't speak, he just watched silently, watching its depth slowly drop from 625 meters to 800 meters, and then stopped.

"It has descended to the limit depth."

"Continue to move forward slowly, sonar pays close attention." Jiang Yanhai said softly.

"yes!"

What is the concept of 800 meters deep sea? The surroundings here are endless darkness, nothing can be seen outside, no light, and almost no living things.

Of course, it is only almost. In fact, there are still creatures in the deep sea, but you don't know what kind of state these deep-sea creatures are.

The submarine is constantly advancing, and the surrounding air seems to be starting to become heavy.

Time passed little by little, just like that, after about half an hour, there was a sudden "dang" sound of a huge impact, as if some huge object hit the submarine, or the submarine directly hit something. object.

The sudden sound seemed to release a huge signal in the deep sea, and following the sound was a huge vibration. Jiang Yanhai grabbed the objects around him with quick eyes and hands.

But the other officers and soldiers in the command room were thrown out by the impact and hit other instruments directly.

What's even more frightening is that with this huge sound, the piercing sound of "crunch" and "crunch" rang out.

You know, such a sound has never appeared before, which means that this submarine is very safe in the deep sea at a depth of 800 meters, and its submarine is strong enough to maintain such deep diving activities.

But now there is such a sound, which means that its shell is damaged!

"Are you okay!" Jiang Yanhai asked loudly.

"fine!"

"It's okay!" All the soldiers agreed to respond, but while responding, Jiang Yanhai saw expressions of fear on their young faces.

If it is said that in this world, the fatality rate of plane crashes is almost 100%, then the submarine crashes in the deep sea... that is absolutely 100%, there is no such word as almost.

Moreover, the kind that even the dead body can't be found.

Every submariner knows what he has experienced, but every submariner has no hesitation when he steps into this position.

Jiang Yanhai wanted to say something else, but there was another "boom" and a more dull impact sound. This time, the entire submarine seemed to be knocked out sideways by a huge force.

With this impact, the two people's fearful "creak" sounded, and at the same time, a harsh warning sounded from inside the submarine.
