Although Bai Shujie has never seen depth charges attack enemy submarines, he knows the performance of his depth charges. Once exploded in water, it has the power of a cloudburst bomb, capable of forming a huge blister in seawater.

Now that it was ready, Bai Shujie gave the order for the first helicopter to attack: "Order: All Mi-2 anti-submarine helicopters immediately leave the scene and return to the vicinity of the destroyer to continue to use towed passive sonar to monitor enemy movements." The dragon immediately rose to a height of 800 meters, and the bomb was set to a depth of 30 meters for the first round of bombing! ”

If you are not afraid of 10,000, you are afraid of what happens, so you ordered the Mi-2 to leave the attack site, because you were worried that "the fire at the city gate will affect the fish in the pond".

Ten minutes later, Bai Shujie saw three huge black barrels suddenly appear under the stomachs of the three dragon helicopters, and they fell into the sea and rushed up huge water columns in a short time.

At this moment, the chief engineer of the Daming 305 ship suddenly roared: "The right full rudder is urgently evaded, and there is a torpedo ahead!" ”

Bai Shujie stared at the depth charge landing point in front of him, and didn't pay attention at all. The Daming 305 ship shook its tail and spun on its own urgently, Bai Shujie stood unsteadily, and fell on the spot!

When he got up embarrassedly, Zhang Bingyang had already grabbed the command platform with both hands and leaned forward to look, Bai Shujie then remembered that it was to avoid the enemy's torpedo, and also climbed to the windowsill to look forward, and six white waterlines had already pounced!

The Daming 305 ship, that is, the Somers-class destroyer built by the Americans, has a standard displacement of 1550 tons, a full load displacement of 2400 tons, and a speed of 38.5 knots. After a left full rudder, the Daming 305 ship rushed out to the right front.

With a "boom-" sound, six white waterlines brushed against the hull of the ship, and the enemy's torpedo attack missed, exposing the position of the submarine at the same time, which was equivalent to sending oneself to hell.

Rumble! Rumble! Rumble!

The three depth charges that had previously fallen into the sea finally exploded at this time, and the huge water column rushed up dozens of meters high.

For the next minute or so, the entire sea was like a boiling pot, and the explosion area was still spraying white air upwards.

"Oh my damn it, it turns out that this is what it looks like after the depth charge explodes!" Bai Shujie didn't know the effect of the explosion now, so he could only look at the expert next to him, that is, Zhang Bingyang, the commander of the Navy: "Bingyang, what do you think of the explosion effect?" Did the enemy's submarine suffer? ”

"The explosion effect is naturally very good, and the power of depth charges is indeed very great." Zhang Bingyang grabbed the binoculars and stared at the sea in front of him, and then said: "The enemy ship dives to a depth of 35 meters, and you just ordered the bomb to be set at a depth of 30 meters, it seems that you don't want to blow up the enemy's submarines, but to sink them." ”

"Now there is no oil on the surface of the water, and there is no debris, which means that the enemy's submarine ship has not been damaged. If my estimate is correct, the little devil's submarine should be sunk by the powerful pressure generated by the big explosion. ”

"If you go beyond their extreme depth and don't have enough power, you're never going to get up. If there is enough power system, they still have a slight chance to rise urgently. ”

"But, in either case, these three submarines are finished, because in front of my destroyers, they can only wait for death! According to the character of the little devils, they should not come up to find death, but will die with their own warships under the water. ”

Bai Shujie nodded, and suddenly smiled weirdly: "Call Xu Jiatai, the commander of the Fourth Fleet, and order his Shennong 601 ocean-going submarine rescue ship to come over immediately and carry out emergency rescue of these three enemy ships." If you don't seize the opportunity to do such a good drill battlefield, you won't be able to find it in the future! ”

The Shennong 601 ocean-going submarine rescue ship is a rescue ship made by Bai Shujie with reference to his flagship "Shihuang 918" battlecruiser.

It is 224 meters long, the waterline is 218 meters long, the maximum width is 35.5 meters, and the draft is 8.2 meters. The standard displacement is 45,700 tons, the full load displacement is 51,200 tons, and the maximum displacement is 61,080 tons. 8 oil-fired boilers, 4 steam turbines, 4 shaft propulsion, 172,000 horsepower. The maximum speed is 37.5 knots, and the range is 9500 nautical miles / 27 knots.

The Shennong 601 ocean-going submarine rescue ship completed its outfitting three months ago, and has been in public tests recently, but it cannot find the target for training.

"I finally get it!" Zhang Bingyang suddenly realized: "No wonder you didn't order to blow up the enemy ship directly just now, but left a glimmer of life." I think you mean two things. ”

"On the one hand, they want to force the enemy ships up, and then take prisoners; On the one hand, you are ready to prepare the enemy to die rather than surrender, but you still salvage him. In short, you just want to get these three submarines, and they are really insidious and vicious enough! ”

Bai Shujie smiled and nodded: "The enemy is constantly emerging new technologies, and we need to formulate corresponding countermeasures according to the enemy's military technology level." Otherwise, it's going to be done behind closed doors, and that's going to kill people. ”

"The best way to understand the enemy's military technology is to directly capture the enemy's weapons and equipment. Even if it doesn't work out this time, it doesn't matter, it's all training anyway, isn't it? ”

At this moment, the Mi-2 suddenly shouted: "Report to the commander: there is an enemy ship that is urgently surfacing up!" The other two are now at a depth of 40 meters and continue to sink slowly. ”

Zhang Bingyang grabbed the microphone and shouted: "Order: The rearguard surface boat is ready for battle, and once the enemy ship floats, immediately launch an attack!" ”

"Don't be in such a hurry!" Bai Shujie hurriedly stopped: "Beware of the little devil's deception, and then blow himself up!" ”

"I know, but I won't give the little devil this chance!" Zhang Bingyang nodded, and then shouted into the transmitter: "Gun Commander: Order the main guns to be ready, and once the enemy ship surfaces, immediately destroy the enemy ship's control tower and naval guns!" ”

Three minutes later, three antennas on top of the conning tower had appeared on the surface of the sea, but they had been blown off. Then the conning tower also rushed out of the water, and a large black fish more than 100 meters long jumped out of the water with a huge spray.

The enemy ship was not yet fully balanced, and the commander of the cannon gave the order: "Open the gun!" ”

The main guns of the Daming 305 destroyer are two twin 88mm high-level dual-purpose guns, with an extremely fast rate of fire. Although it was not fully aimed, it was less than three kilometers away, 4 guns covered it, and half of the shells hit the control tower of the enemy ship.

Of course, it was not completely destroyed, and it is impossible to destroy.

Zhang Bingyang gave this order to test the enemy's true intentions. If you want to surrender, then hurry up and raise the white flag. If the negative side resists stubbornly, and even wants to play self-destruction, the helicopter hovering in the air is not dry.

Bai Shujie held a telescope to take a closer look at this submarine, and found that it was indeed newly built, because the hull was still as smooth as new, indicating that the time of launching was very short.

According to the time process, this should be the first type C submarine of the little devil, the serial number is the type 16 submarine of the I, which started construction on September 15, 1937. Later, 7 more ships were built, all of which were sunk by the Americans during the Pacific War, and the last one, the Yi 24, was captured.

The total length is 109.3 meters, the total width is 9.1 meters, the draft is 5.1 meters, the water displacement is 2184 tons, the water displacement is 3561 tons, two horsepower diesel engines (12400 horsepower), one electric motor (2000 horsepower), the maximum speed on the water is 23.6 knots, and the maximum speed in the water is 8 knots;

111 km (60 nautical miles)/3 knots in water, 25,900 km (14,000 nautical miles)/16 knots in water; The bow is equipped with 8 533mm torpedo tubes and 20 torpedoes; Deck 50 times caliber 140mm main gun, 2 25mm anti-aircraft guns. Deck-sealed hangars, loading 1 water bomber, later models were abolished.

The biggest problem with the Little Devil submarine is still the implementation of the old tradition of "firepower first", using all the space to store ammunition. As a result, the crew was 101 people, but there were only 97 cabins, and 115 people were actually needed to operate.

The worst thing is the toilet design, which is one of the worst places in the world. It's just a row of round holes above the cabin where the excrement is kept, and the capacity inside is so small that it will overflow if you are not careful, and then it will stink.

And sailing in the sea waves, it is absolutely impossible for you to keep the ship from shaking. The fermentation effect caused by the shaking of the hull of the boat made the toilet the only "quiet" area on the boat that no one approached, and it can only be described as "terrifying".

The enemy came out to surrender.

As soon as the main guns of the Daming 305 ship fired a salvo, the white flag was already raised. Then the sailors of the little devils began to appear, all of them on the deck in panic.

The "Dahan 905" North Carolina-class battleship, the "Shennong 601" submarine lifetank, the Tianlong light cruiser, and the Chunfeng destroyer of the Fourth Rescue Fleet rushed over one after another after receiving Bai Shujie's order, and in less than three hours, they temporarily formed a huge mixed formation.

There was no need for so many warships to gather here, so Bai Shujie ordered the light cruiser Tianlong to immediately return to the Jiaodao base to garrison, and by the way, escort the submarine that had surrendered back.

The submarine lifeship "Shennong 601" began its first sea operation. The rescue ship has four rotating booms on it, and the "underwater rescue tentacles" are lowered into the sea by means of a guò hoist.

After Bai Shujie's "guidance", the "underwater rescue tentacles" developed by the Institute of Physics for rescue ships are actually four adsorption electromagnets, which can automatically detect ships underwater.

The winch behind each tentacle lifts 36 tons, which adds up to 144 tons. Compared to a sinking submarine, this weight is not worth mentioning.

However, Bai Shujie believes that it is impossible for all the compartments of the damaged submarine to be flooded, as long as it is given a certain buoyancy, so that the damaged submarine can float a certain distance, and then anchored on the rescue ship, and then fixed with a main winch with a lifting force of 72 tons, and slowly towed to the shallow water, so that the divers can be arranged to go down for the final lock.

If the submarine cannot be allowed to leave the seabed after applying a lifting force of 144 tons, Bai Shujie feels that with the current technical conditions, the possibility of salvage and rescue has been completely lost.

Because of the hundreds of meters deep in the sea, it is impossible for divers to go down, and now it is possible to study underwater machines in their sleep.

What Bai Shujie wants to verify with his own eyes today is whether the four "underwater tentacles" can find that the submarine is slowly sinking, and at the same time can prevent the submarine from continuing to sink. This is the most critical step.

Bai Shujie didn't care about whether he could salvage the enemy's two submarines. What he hopes to test is whether his rescue theory can be established.

Even if you fail, you have to find the reason for it, and then you can continue to improve. Scientific research is not an easy road, and Bai Shujie is mentally prepared for complete failure. But what the final result will be depends on the results of today's experiment.

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