Traveling through the sword to engage in military industry

#396 - Ride a whale to explore the Pacific Ocean!

At Midway Island, Ma Yingwei harvested the first batch of vegetables, nearly a hundred kilograms of Chinese cabbage, lettuce, and water spinach.

With full-spectrum LEDs, Ma Yingwei could adjust the lighting time. By providing longer illumination than the normal outdoor exposure, the vegetables' growth cycle was shortened. The cultivation in organic soil and the scientific allocation of organic fertilizer, coupled with the absence of external pests and diseases, made the vegetables on the submarine grow even more fresh and tender.

They were even good enough for vegetable salads. So, even just blanching them in boiling water and serving them cold, these vegetables were devoured by everyone!

They alleviated the longing for fresh food after eating bean sprouts and canned food for a long time.

Although they couldn't eat their fill, this supplement made the soldiers feel that life on the submarine wasn't much different from life on land. Except for being careful not to make noise and speaking in low voices, the physical and mental states of the officers and soldiers piloting this long-range submarine for the first time didn't change much.

This somewhat disappointed the two doctors who had hoped to show off their skills.

After all, under such harsh conditions, everyone was in excellent health, with no one getting sick or developing mouth ulcers. It was almost unscientific.

In this era, under normal circumstances, even on surface ships, if they were at sea for a long time, most of the sailors would develop some ailments.

However, this was this timeline, with the knowledge from the main world to draw upon. Ren Zhong had long provided detailed technical information for the living support of the nuclear submarine's officers and soldiers, which is why the agricultural experts and doctors were on board for the maiden voyage.

Hard work was important, but if conditions allowed, improving the living conditions of these brave men was even better.

More than ten days later, the 001 nuclear submarine passed through the Amukta Pass and entered the Bering Sea.

After entering the Bering Sea, the atmosphere on the submarine suddenly became tense.

Thanks to the information from the main world, the submarine had basic information about the oceans it planned to pass through, obtained by Ren Zhong from public channels.

Therefore, after entering the Bering Sea, Liu Wensheng convened a general meeting.

"Comrades, the test is upon us!" Liu Wensheng said through the submarine's communication system.

"In a few days, we will reach the area around St. Lawrence Island and the Bering Strait, where the ocean depth will be only between 30 and 50 meters. Our submarine will face comprehensive monitoring from the air and sea by the two superpowers. There is a high probability that our target will be exposed, attracting pursuit and even attacks from the enemy!"

Liu Wensheng's voice echoed in every corner of the submarine.

Everyone listened in solemn silence. In fact, these things had already been explained before departure. Passing through the Bering Strait would be one of the most dangerous sea areas of this voyage.

Here, there was nearly 800 kilometers of sea area with a depth of less than 100 meters, and it was located in a place where the two superpowers bordered each other. This was one of the most densely monitored hotspots on the Blue Star!

The 001 nuclear submarine had no other way to deal with these monitoring systems but to face the difficulties head-on!

"Therefore, I require all officers and soldiers on board to stop all activities that may cause noise in three days, including cooking in the kitchen and maintenance work on the submarine. All maintenance work must be completed within three days to ensure that the entire submarine will not emit noise caused by maintenance work in the coming days. Except for observers reporting the situation, all officers and soldiers must communicate in writing unless necessary!" Liu Wensheng reiterated the requirements.

The officers and soldiers, who were disciplined and obeyed orders, had no objections to these requirements. They would respond to Liu Wensheng's request with practical actions.

Internationally, the decibel used to calculate underwater noise is the same unit value as the one used to measure air noise in everyone's hands; however, the reference points for evaluation are different.

Generally, 0 decibels on land refers to a sound pressure of 20uPa, but in underwater acoustics, 1uPa is 26dB, which means there is a difference of 52 decibels. The so-called ocean background noise of 95dB is actually equal to 43 decibels of noise in the air, which means that the natural sounds of the sea, such as water currents and schools of fish passing by, start at 43 decibels, which is about the same as the humming of our home refrigerator running.

The current top-level submarines have a noise level of about 110 decibels. The crude things from the Big Bear are mostly still around 140 to 150 decibels. That is to say, the noise emitted by all the mechanical equipment of a top-notch quiet submarine is about 58 decibels, which is equivalent to people talking face-to-face!

Therefore, after a submarine enters combat status, if people are talking, it will have a relatively large impact on the submarine. Even if the submarine is a sealed space that blocks some of the human voice, the submarine's steel plates cannot be very thick, generally around 30 millimeters, some places may be thicker, but some places may be thinner.

Places like torpedo launchers need to leave channels for launching things.

Therefore, the noise inside the submarine should be reduced as much as possible.

Not cooking is not a big problem.

In fact, in the main world's timeline, early submarines didn't have any hot food to eat. Bread, canned food, instant noodles, and instant rice were all in ample supply.

In terms of the diversity of convenience foods, only Dongda in this timeline has it all.

These food products are still Dongda's second-largest source of revenue, second only to the textile industry.

However, after electronic products such as televisions and microwave ovens began to increase in volume, their growth rate was amazing. Ren Zhong estimated that in a few years, they would surpass the previous two traditional industries and begin to rise to become the largest industry.

In the submarine, Liu Wensheng's voice was still transmitting, "Comrades, at this moment of decisive battle, I require all officers and soldiers to strictly demand themselves, strictly abide by discipline, operate rigorously, and activate first-level combat readiness. Torpedoes are in a ready-to-fire state, ready to fight at any time."

Although fighting was the last resort, Liu Wensheng would not passively take a beating when attacked by the enemy and would inevitably choose to fight back!

According to the current weapons and equipment on the submarine, there are a total of 26 533mm heavy torpedoes. While it might be an exaggeration to say they could wipe out an entire fleet, they definitely have a good chance of taking out a few submarines or destroyers that attempt to chase or eliminate them.

Don't forget, a single one of these heavy torpedoes can take out a destroyer!

As for submarines, getting hit means certain death!

Otherwise, with the Qin-class nuclear submarine's superior underwater speed, enemy submarines and even torpedoes of this era wouldn't have much of a way to deal with it.

The only relatively dangerous thing is a fast destroyer releasing heavy depth charges!

"Comrades! Fortune favors the bold. Our No. 001 nuclear submarine is undertaking a groundbreaking event in the history of the Heavenly Dynasty's navy. Every step we take today is a new step that no one has ever taken before!

For victory, follow orders, and fight to the finish!"

Liu Wensheng used three clean and powerful words as the ending of his pre-battle encouragement, causing all the officers and soldiers in the submarine to become excited. They silently clenched their fists, raised them high in the air, and waved them non-stop, venting their excitement.

Even Ma Yingwei, an outsider, felt his blood surging and his heart rate soaring to 180!

The journey so far had been too smooth, making everyone forget that this was a difficult battle!

After all, in the vast Pacific Ocean, with the No. 001 nuclear submarine's superior diving depth, there was basically no chance of being discovered by the enemy. In the enemy's mind, there is currently no concept of a submarine that can dive to a depth of 400 meters!

Therefore, whether it's sonar or other detection tools, they wouldn't be researching such deep seabeds.

So, in the Pacific Ocean, as long as the navigation direction is maintained and there are no underwater mountains blocking the way ahead, it's full speed ahead!

The current nuclear reactor has no distinction between economic cruising speed. The reactor fuel design, with a lifespan of up to ten years, allows for a full-throttle global voyage!

Entering the Bering Sea, the first three days were still deep sea. Liu Wensheng directed the submarine to advance at full speed, and the maintenance team's engineers conducted a comprehensive final inspection, confirming that the submarine had no mechanical, electrical, or reactor abnormalities.

After three days, when the depth of the sea gradually increased from several hundred meters to less than one hundred meters, Liu Wensheng began to reduce the submarine's speed, slowly decelerating to 18 knots/hour, and then stabilized the submarine's depth at 40 meters.

All unnecessary extra tasks and movements on the submarine were stopped, and even walking inside the compartments was reduced. If not necessary, the officers and soldiers stayed at their posts.

Even those reading books began to carefully turn the pages, no longer making any noise.

"Chief, active sonar completely shut down, passive sonar activated!" On the command screen in the command module, the latest news was flashing. Even the submarine's avionics information was now being transmitted silently via computer.

"Everything is normal at the moment."

"Communication frequency reduced, already entered low-frequency response mode."

Low-frequency response, according to the prior agreement, the contact with the headquarters was reduced from a frequency of 10 minutes to once an hour, and the signal transmitted to the satellite was more concise, with only a longitude and latitude information indicating that everything was normal!

In this way, the headquarters can see the current location of the No. 001 nuclear submarine through the change in the track, and predict the location it should reach in the next hour.

It can be said that the richest content is expressed with the least amount of information.

Liu Wensheng's command computer screen is the latest 18-inch large screen, which can see the status of most of the key equipment of the entire ship and the current main physical state of the submarine!

Therefore, even without anyone reporting, he can understand the situation of the entire submarine through the sensor data on the entire ship.

With the reduction in speed, the noise of the No. 001 nuclear submarine was also reduced by several decibels. Now it's just over 100, which, according to the decibel standard on the road, is about the state of whispering.

However, Liu Wensheng didn't dare to be careless.

He saw him concentrating on every line of information flashing on the command screen: speed, depth, seabed height, seabed topography ahead...

There was even a camera monitoring screen next to it, real-time transmitting the seabed image in front of the submarine.

Schools of fish, being rammed by this big black fish all the way, the fish in front seemed to know they couldn't afford to provoke it, and fled in all directions!

If there were old fishermen who had been fishing at sea for many years to see such a scene, they would definitely say involuntarily that the marine resources here are really good.

Suddenly, a warning appeared on the command module!

"Whale pod ahead!"

Liu Wensheng's heart tightened!

His eyes left the command screen and looked at the video monitoring screen next to him. Sure enough, a pod of huge whales, orcas, appeared faintly in the distance!

This is one of the sea overlords who are not afraid of anything. Facing the huge nuclear submarine, they will not be afraid, and will still rush towards the nuclear submarine!

"Reduce speed, turn the rudder for emergency avoidance!" Liu Wensheng's forehead suddenly broke out in sweat. If they were to collide head-on, and both sides used their full strength, the collision force would be enough to collapse the nuclear submarine!

You must know that the full speed of orcas can reach an astonishing 55 kilometers/hour! Almost the same as the design speed of the No. 001 nuclear submarine!

If there is a full-speed head-on collision, the weight of an adult orca can reach five or six tons, which is equivalent to a truck with a speed of 110 kilometers per hour crashing into it!

Even if the orca's body is slightly lower than the strength of steel, the rigidity of the submarine may not be able to withstand such a full-speed impact!

And in the ocean, orcas don't understand what avoidance is!

After the speed slowly decreased, the orca pod seemed unaware, and continued to maintain a normal diving speed forward. As for the nuclear submarine in front of them, some smaller young orcas wagged their tails and chased up, preparing to try their mouths, but they broke their teeth with a bite!

Then some angrily slapped the huge hull of the nuclear submarine with their tails and swam away! The orcas next to it seemed to know that this was not good food, and swam past without even looking at it.

In this way, the nuclear submarine, which had reduced its speed, was like a big fish in the sea. The orca pod naturally separated the water flow and passed the nuclear submarine on either side, passing by without incident.

Liu Wensheng squeezed a handful of sweat and let out a long breath. You must know that this is a large pod of more than twenty orcas. If it was startled and crashed around in the water, even if it won, it would not be easy.

It's not good to get hit with a dozen holes in it.

Fortunately, a real-time monitoring TV was installed, giving Liu Wensheng some time to avoid it.

In this sea, anything can happen. Liu Wensheng's originally tense nerves were sounded the alarm again.

"Reduce speed to 15 knots and cruise, pay attention to observing the fish schools and seabed conditions!" After typing on the keyboard for a while, Liu Wensheng issued a new order.
