The high-power electromagnetic sensor that Bai Shujie wants to verify turns out to use a 4,800 kilowatt generator to create a powerful electromagnetic field, and then at the front end of the sling of four cantilever winches, a permanent magnet with a size of 750mm ×750mm is connected, which can rely on strong magnetism to find metal objects, and only adsorb on this metal object, as long as you don't turn on the power supply, it will not fall off.

After Bai Shujie's explanation, all the experts from the Institute of Physics of the Comprehensive Research Institute said that it was theoretically feasible, and later succeeded in lifting a 150-ton weight on land. But it's a big unknown how effective it will be when it is used in water.

After more than ten failures, the good news finally came at more than two o'clock in the morning the next day: at a depth of about 45 meters underwater, a tentacle "grabbed" a heavy object! The number jù indicated by the oil pressure gauge of the winch indicates that the current lifting force has reached 30 tons.

At four o'clock in the morning, Bai Shujie finally got a piece of news that made him feel more at ease: "There are already three tentacles that have grabbed the heavy object, and they are now able to drag it slowly, and the moving speed is about 18 meters per minute." ”

Bai Shujie calculated in his heart that moving 18 meters per minute would be 1 kilometer in an hour. 75 kilometers, it takes three days and three nights to move back, which is too damn time-consuming, right?

At about half past four in the morning, the fourth tentacle finally grabbed the heavy object, and the Shennong 601 rescue ship finally magnified its courage a little, and its moving speed increased to 42 meters per minute, which is 2.5 kilometers per hour.

Bai Shujie suddenly remembered that the seabed in the northern part of the Yellow Sea from the mouth of the Yalu River to the mouth of the Datong River, due to the large tidal range and rapid tidal current, and the large amount of sediment carried by the Yalu River and the Datong River washed into the seabed, there are large tidal ridges in the northeast direction, and the seabed is very undulating.

Thinking of these common senses, Bai Shujie hurriedly said to the Guan Tong chief of the Daming No. 305 destroyer: "Inform the Shennong No. 601 ship that there will be a large number of tidal ridges near our Jiaodao. Let them test if they can lift the weight as much as possible. On the premise of ensuring the safety of your own warship, you don't have to worry about failure, although you can rest assured that you can do it boldly. ”

With Bai Shujie's supreme instructions, Xu Jiatai, the commander of the Fourth Fleet, also completely let go, and ordered all four cranes to be slowly lifted up and raised by 10 meters.

Unexpectedly, Xu Jiatai's order went down, and it didn't take long for something to go wrong.

It turned out that no coincidence or coincidence that the three tentacles were concentrated in a small area. As a result, the bow of the submarine came out of the water directly, just against the front deck of the "Shennong 601" rescue ship.

That is, this captured submarine was erected directly in the water! The I-type submarines of the little devils are generally more than 100 meters long. The depth of the Yellow Sea is only 40-50 meters. This time it was erected, and more than half of the submarine was exposed to the surface.

Now it's hard to ride a tiger, so anxious that fleet commander Xu Jiatai doesn't know what to do.

If it is put back now, this submarine has lost its original balance, and if it rolls in the water, it is likely to hit the keel of its own rescue ship.

A big guy of more than two thousand tons, as long as he hits it casually, the keel of any battleship cannot withstand it.

It's four or five o'clock in the morning, and although the nearby warships have turned on their searchlights, it is still very difficult to operate specific solutions.

Bai Shujie was also very anxious on the Daming No. 305 destroyer not far away, he directly grabbed the microphone and shouted: "The rescue sailor put on a safety belt, immediately go to the rescued battleship and hang another cable, and use the power of the windlasse to put it back again." Hold the cantilever crane and never let go! ”

It was only at this time that Bai Shujie realized that just having a rescue ship was not enough. The shipyard had to hurry up and build another rescue ship of the same type, and then the two could be put on board together to tow the sunken warship out of the sea.

Speaking of today's processes, Bai Shujie believes that the magnetic sensor designed by the Institute of Physics has great practicability.

Not only can it be used on rescue ships, but it should also be able to modify and improve the magnetic detector of mines, so as to improve the hit rate.

If it can be linked to a digital processor and then combined with a sonar system, it should be able to play a bigger role.

Busy until half past six in the morning of the next day, this submarine was finally locked by the windlass of the "Shennong 601" rescue ship.

Now that the sky is bright, two 5,000-ton tugboats that received a call for help have arrived at the scene.

At half past seven o'clock in the morning, the "Shennong No. 601" rescue ship finally transferred the "scourge" to the two tugboats, broke away from the "close contact" with the submarine, and avoided a more embarrassing situation.

At 7:55, all the battleships suddenly remembered the siren, and all the announcements shouted at the same time: "A huge group of aircraft is flying towards us 180 kilometers to the south, and all battle positions are immediately ready for battle!" ”

As soon as Bai Shujie heard the report on the enemy's situation, he suddenly broke out in a cold sweat. The main battleships concentrated here now are 1 North Carolina-class battleship numbered "Dahan 905", and then the "Daming 305" destroyer on which they are riding, and the rest are operational ships. Not only was it slow, but it also had no anti-aircraft fire.

At this moment, the walkie-talkie specially equipped for Bai Shujie shouted: "Report to the commander-in-chief: I am Zhang Nianzu." The enemy dispatched more than 70 warplanes, took off from the Fukuoka line, and swooped north across Jeju Island. ”

"24 attack planes have taken off from Quanzhou Airport to attack on the side, 24 attack planes have taken off from Jiangnan Airport to intercept them, and 24 Mustang attack planes have taken off from Miaoxiangshan Airport, and they are expected to arrive at the operational sea area in 20 minutes."

When Bai Shujie heard that the Air Force had taken measures, his heart finally settled down a lot, but he felt that this kind of strength was far from enough.

Therefore, he grabbed the walkie-talkie and shouted: "Order: 6 heavy bombers and 24 light bombers at Jeonshu airfield immediately take off and bomb the Fukuoka Shikashima Naval Base!" ”

"Order: 6 heavy bombers at Jiufengshan Airport immediately take off for reinforcements and bomb the Sasebo Military Port in Nagasaki! The Black Widow carrier-based aircraft of the First Fleet immediately took off to cover the bombers to complete their combat mission. ”

After thinking for a while, Bai Shujie began to call the headquarters again: "Gan Tong: Immediately order all the coastal defense forces and air defense forces to enter the combat state and go all out to meet the air raid of the little devil!" All radar units and sonar units were ordered to closely monitor the sea surface to prevent the enemy's three-dimensional attack. ”

At this time, Xu Jiatai, commander of the Fourth Fleet, had already ordered his flagship, that is, the "Dahan 905" North Carolina-class battleship, to move forward at full speed, passing the "Daming 305" destroyer on which Bai Shujie was riding in the southern sea area, and all the anti-aircraft guns had been raised high and were ready for battle.

With the sound of a whistle, the Glory-class aircraft carrier with the second fleet's side number "Daqin 802" and the two Yamato-class battleships with the side number "Dahan 903" and "Dahan 904" that had just returned appeared in Bai Shujie's sight.

The first batch of 12 Black Widow attack aircraft on the "Daqin 802" Tereglory-class aircraft carrier has already begun to form in the air; The second batch of 12 aircraft is taking off one after another.

Three battleships and an aircraft carrier blocked Bai Shujie's "Daming 305" destroyer behind him, making him anxious but unable to get by.

Not only that, but eight Mi-2 helicopters have also arrived over the "Daming 305" destroyer, and it seems that they are ready to be the last shield.

In fact, when he saw the appearance of the "Daqin 802" Brilliant class aircraft carrier, Bai Shujie was already relieved. The fighters of the little devils are currently not capable of fighting the Mustang attack aircraft and the Black Widow twin-fuselage attack aircraft at all. Now nearly 100 fighters have begun to take to the air one after another, and it is impossible for the little devil's plane to break through the defense line.

With a roar approaching, Bai Shujie saw that his huge fleet had reached the top of his head, and it was an air formation command plane hovering over the "Daming 305" destroyer.

"Report to the commander-in-chief: The interceptor fighters that took off from the Jeonju airfield have bitten the enemy planes over the island of Montenegro and are fighting fiercely. The 20 biplane fighters that took off from the Jiangnan airport have already arrived at the battlefield. The 20 Mustang that took off from Myohyangsan Airport have already spotted the enemy and are moving at full speed. ”

"Commander-in-chief, rest assured, we are confident that we will intercept the enemy on the Weng Jin line, and we will definitely not let them continue to advance half a step north!"

As soon as Bai Shujie heard the voice of Air Force Commander Zhang Nianzudi, he was immediately angry and scolded: "Fart! What is there to worry about Lao Tzu? Brothers are one life, and Bai Shujie will not have half a life, let alone more than others. You hurry up and order the pilots to carry out in strict accordance with the requirements of 'save yourself and destroy the enemy'! ”

"All air operations are to be carried out in accordance with tactics, and no one is allowed to violate tactical principles and fight the enemy. It doesn't matter if the little devil wants to fly to Russia, who the fuck wants to fight the little devil's fighter fighter, and when he comes back, Lao Tzu will kill him immediately! ”

Zhang Nianzu's air formation command plane is shared with all fighters. Therefore, Bai Shujie's angry scolding boosted the morale of all the soldiers.

"Report to the Commander-in-Chief: The enemy aircraft formation has discovered our bomber formation and is now preparing to turn around and go back for reinforcements. How to deal with it? ”

Bai Shujie said loudly: "The Mustang attack aircraft and the Black Widow attack aircraft use their speed and altitude advantages to entangle with the enemy aircraft, don't let them do whatever they want." Other fighters and interceptors immediately returned to their homes to alert the land bases. ”

"Order the bomber formation to maintain an altitude of more than 4,000 meters, and the enemy fighters will not curse. Today, there is no need for bombing accuracy, only bombing intensity, as long as the cloudburst bomb is dropped on the local territory of the little devil. ”

In this sudden air battle, nearly 300 planes were dispatched by the enemy and us, but unfortunately Bai Shujie did not see it in the end.

With the return of the air formation command plane, Bai Shujie knew that the air battle was over. It is not yet known what the specific results will be and what the specific losses will be.

In any case, Bai Shujie was very satisfied with the whole process of this day and night.

On the one hand, the fact that their own fleet and fighters can be pulled out at any time shows that the recent training has been very fruitful, and this is a huge progress.

On the other hand, regardless of the specific outcome of the air battle, at least this time three more enemy submarines were killed, breaking the enemy's conspiracy to sneak attack Pyongyang's front line.

Another point is that the overall design idea of the rescue ship is correct, the key is that the experience is insufficient and the number is not enough, which needs to be slowly improved.

With the experience of salvaging the first submarine, the next step is to let the rescue fleet practice here and try to get the other one back.

After all, what happens next, let's see how it will be broken down next time.
