All-Electric Propulsion is naturally very advanced, and the country is in a leading position in this regard. However, generally large ships use conventional drives. The main reason is that the electric propulsion system required by large warships is too terrible, and currently no country is very good at it.
Especially ultra-large warships such as aircraft carriers that can weigh tens of thousands or even more than 100,000 tons.
As for submarines, it goes without saying that All-Electric Propulsion has an extremely powerful mute effect and has advantages in various aspects such as acceleration performance.
Hearing Jiang Yan Hai's words, the soldier at the helm immediately said, "Should you turn off Nuclear Reactor and use All-Electric Propulsion mode?"
"Yes!" Jiang Yan Hai agreed, but was surprised in his heart, because the soldier said so directly, which means that the submarine's Nuclear Reactor can be turned off at any time... and not only can it be turned off at any time, this means that its battery can be used for an extremely long time.
Nuclear Reactor is not like a diesel engine. A gasoline engine can be shut down at any time and ignited at any time for use.
At the dock, if the submarine Nuclear Reactor is shut down and then restarted, it will take about 12 hours, because it has to gradually increase 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, it must be increased slowly.
This is mainly to prevent thermal shock, just like pouring hot water directly into a cold glass.
And turning on the reactor in this way requires electricity. If you are at the dock and have shore power, there will be no problem, but in the sea you will need batteries.
In fact, if a 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 higher temperature. In this way, if you want to start it, it can be completed within two or three hours.
However, this thing will basically not shut down at sea, but it can be shut down at will here, because the cooling system of Nuclear Reactor is one of the main sources of noise of Nuclear Submarine.
Many reactors are useless if they are stopped, because the cooling system still needs to be running, 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 Yan Hai knows.
Its technology is undoubtedly very advanced. If the reactor can be turned into a gasoline engine or a diesel engine that can be stopped at any time, then the usability of this thing will be very high.
"Report the current status of the submarine." Jiang Yan Hai 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, the enemy's voiceprint characteristics have not been detected. The voiceprint characteristics currently locked by the computer are all natural creatures."
At this time, the submarine naturally uses passive sonar, and it is impossible to use active sonar. Active sonar is equivalent to exposing itself. They don't even know where the enemy is, so it is naturally impossible to use active sonar at this time.
"Understood." Jiang Yan Hai nodded. He found another good thing. This submarine contains a huge database of natural biological voiceprints. Although this voiceprint database may not be the same as the real creatures on the seabed, these data are all good things.
To be honest, Jiang Yan Hai has no research on the combat tactics of submarines. He is just trying to catch a duck to the shelves. However, combat operations are sometimes the same. Without considering other weapons and equipment, you only need to consider why the other party is doing what they do.
In such a state, if the enemy searches for them, they will definitely come to arrest them.
Submarine warfare sometimes requires patience, and the enemy may not discover them immediately.
"Slowly dive to the extreme depth." Jiang Yan Hai thought for a while and 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 entire submarine was constantly increasing. Jiang Yan Hai did not speak. He just watched silently, watching its depth slowly drop from 625 meters to 800 meters, and then it began to stop.
"It has descended to its ultimate depth."
"Continue to move forward slowly, and pay close attention to the sonar." Jiang Yan Hai 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's only almost. In fact, there are still creatures in the deep sea, but you don't know what kind of condition these deep sea creatures are in.
The submarine continued to advance, and the surrounding air seemed to become thicker.
Time passed little by little, and just like that, about half an hour later, suddenly a huge impact sound came, as if some huge object hit the submarine, or the submarine directly hit something.
The sudden sound seemed to release a huge signal in the deep sea, and with the sound came a huge vibration. Jiang Yan Hai grabbed the objects around him with quick eyes and hands.
But the other officers and soldiers in the command room were thrown away by the impact and hit other instruments directly.
What's even more frightening is that along with this huge sound, the sound of "crunching" and "crunching" is heard, which is so heartbreaking that metal is squeezed.
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 diving depth activities.
But now there is such a sound, which means that its shell is damaged!
"Are you okay?" Jiang Yan Hai asked loudly.
"It's okay!"
"It's okay!" All the soldiers agreed to respond, but while responding, Jiang Yan Hai saw expressions of fear on their young faces.
If the death rate of plane crashes in this world is almost 100%, then submarine crashes in the deep sea... it is absolutely 100%, without the word "almost".
Moreover, the kind where even the body could not be found.
Every submariner knows what he is going through, but every submariner has no hesitation when he steps into this position.
Jiang Yan Hai What else was he going to say, but another duller "boom" sound of impact came directly. This time, the entire submarine seemed to be directly knocked out sideways by a huge force.
With this impact, the two men heard a frightening "crunch" sound, and at the same time, a harsh warning sound sounded inside the submarine.
