Of course, judging by the trajectory of the enemy's fleet, it did not completely circle Izumo for collective anti-submarine maneuvers. Since last night, the Yunon, which is running at the front, has been very inactive, whether it is the 419 report or the deliberate exposure of the periscope, it has not made a positive reaction, judging from the speed of the tracked host, it even speeds up, but it does not turn around, deliberately widening the distance from Izumo.

"The enemy ship Nagara on the left flank approached at high speed, at a distance of 25 chains. Flag Wind is approaching behind, and the distance is 90 chains away. ”

Cheng Dayang sat in the command cabin, looking at the two more dexterous enemy ships, which were crossing a huge circular track, leaning towards the place where he showed his periscope just now.

419 at a speed of 18 knots, snatched in front of the bow of Nagara, according to the trajectory calculation, in the next 2 minutes, 419 will be close to Nagara, and at a certain moment the distance between the two sides will be close to 300 meters, of course, such a distance is not enough to support the attack of such a crude benzene weapon as a deep bullet. In addition, it is unlikely that the enemy will be able to predict the position of 419, and the speed of this nuclear-powered submarine will inevitably be far beyond the enemy's expectations. Although it is the duty of every captain to take the initiative to avoid the enemy's anti-submarine destroyers, at this moment, Cheng Dayang does not want to modify the course, he feels that it is unnecessary. In order to cope with the swerving or slowing down of an old ship that is nearly seventy or eighty years behind? It's unseemly to say anything. Of course, his other intention is to take advantage of the enemy's rumbling blades to add some fear of imminent battle to all posts in the submarine, and it would be better if the enemy could throw a few deep water* down. Too many people here (in fact, including himself) have not yet fully entered the combat state, and at this point, Lin Xiuxuan is one step ahead of them.

"Intercepted the second batch of targets, azimuth 115, the position is backward, it is moving away, it can't keep up with us."

"It seems that the flag wind behind is slowing down, is this preparing to drop a deep bomb?" Cheng Dayang glanced at the enemy's track, which is a typical anti-submarine method in the World War II era, the captain judges the route and depth of the enemy's submarine, and then merges the routes, uses a higher speed to drive over the head of the submarine, drops bombs all the way, and prays to hit.

"The Japanese judge that we are still close to Izumo." The commissar said.

"Even if you guess what, the route is so outrageous, I'm anxious for them."

"Didn't find active enemy sonar?"

"Not yet."

"They only have passive listening equipment in the bow, but even if they can hear it, they can only determine the bearing, not the distance." Chu Aiyun added.

"The enemy ship dropped bombs. Something fell into the water behind the flag wind. ”

"Not bad, look at their judgment of depth."

Cheng Dayang said and pinched the stopwatch, he wanted to see the explosion time. The fact that the enemy panicked and threw deep water 1 km away* indicates that they are completely bottomless, and that this thing may blow up the ears of the nearby ship's listeners, which will make them even more blind.

"Izumo is still doing anti-submarine evasion?"

"Yes, sirens can be heard."

"Qiyun threw another one."

"Well, the depth is very large, probably thinking that we were sitting at the bottom and waiting for them to drop the bomb."

At the same time, Ino Shaozuo on the Qiyun was also pinching the stopwatch and watching the timed drop* from the rear. The 1,300-ton destroyer was blocking the submarine from the rear according to the signal sent by the Nagara, hoping to sink or force the submarine to surface. The water depth in this area is only 30 to 50 meters, which is quite unfavorable for submarines.

Another * rolled into the sea from the rear launcher orbit of Class A. At the same time, a few dozen meters away, the sea suddenly surged upward, and it was the first deep-water* explosion that had been dropped before. If it happens that the submarine is on the side, it can be killed.

The sound of continuous deep bomb explosions immediately disrupted the tracking of the listening personnel on all nearby ships. The advance of SCP-419 was not inaudible, especially as it passed within 2 kilometers at nearly 20 knots, and some movement could still be heard, but for now, the problem was solved.

"Their tactics were intercepted by Nagara and the flag was bombed."

As Cheng Dayang spoke, the enemy's deep bullets exploded continuously. Each time it was 1 km away and getting farther and farther away.

"Stick to the bottom of the sea, and we'll drill under Izumo."

419's high-frequency sonar scans the seabed at frequencies that cannot be heard by the human ear, which allows 419 to obtain the seabed topography instantly.

The nuclear submarine quickly approached Izumo, a few kilometers away. Leave Nagara and Qifeng behind. Judging from the enemy's movements, it was completely hooked.

It can be heard that the main engine of the Izumo is struggling to rotate and is constantly changing course, as if it is thought that this will avoid a submarine attack, and if Cheng Dayang is allowed to launch a direct voyage* to attack such a target that is already guarded and not low in speed, it is indeed unlikely.

419 quickly passed through a bubble a few hundred meters behind Izumo, and Nagara and Kikaze in the east were trying to "anti-submarine" and had already dropped the 25th*, while the Yukumo ran away and seemed to be heading in the direction of Shandong.

Twenty-five minutes later, 11 kilometers west of Izumo, 419 resurfaced to periscope depth, and now she occupies the most advantageous position, completely undisturbed by any kind. At this distance, Izumo also has a hard time spotting tiny periscopes with the naked eye of an observer, unless it has radar.

Cheng Dayang reversed his training cap, turned the periscope, and re-observed the target, and at the same time, Chu Aiyun took over the command and issued a series of instructions, making the submarine turn around 300 degrees and roughly aim the bow at the target.

At the same time, the optoelectronic mast transmits the image to the large display of the command module, and it can be seen that at sea level, the battleship is heading north. The second electronic mast was raised, allowing SCP-419 to regain control of the aerial drone, which had been flying on its own in accordance with the set navigation route.

"Look, there's not a single person walking around on the deck of Izumo. The main gun is pointed east, and it seems that it has been fooled. ”

"Well, the drone is ready to drop bombs."

Judging from the condescending picture, the huge armored ship, still in a huge turn, has white spray rolling up in the rear, and several chimneys are emitting smoke.

"Smoke interferes with laser irradiation, we have to wait."

"No. 1 No. 2 * Da Dingshen."

"No. 1 and No. 2* are in charge."

"* Tube filling."

"Fill the water."

"Open the *tube."

"The fire control is solved, and the target is within the feasible domain of the attack. It is expected to arrive at 700 after launch. ”

"Launch No. 1." Cheng Dayang held the intercom and gave an order, "Launch on the 2nd." ”

The submarine was shaken, the first one * drilled out* the tube, followed by the second. He was determined not to launch a third*, 2 should be enough.

"The drone is steady, and the first* should at least hit around the chimney and blow up a gap."

"At the moment the wind is in our favor, the smoke is weakening, and target designation can be carried out."

"Wait, wait* closer."

Cheng Dayang ordered to continue waiting, he had to wait for the 2* that were still moving in the sea to approach, it was best to let all the attacks occur at the same time in a very short time, which could not only paralyze Izumo at once, but also make the rest of the enemy ships in the east unable to react, so that the effectiveness of Shu Ping's enemy poison attack could reach the maximum.

"When Izumo resumes course, smoke may continue to disrupt the laser designation."

Cheng Dayang hesitated for a moment, and now he had to make an accurate judgment immediately.

"Bomb dropping."

At an altitude of 4,000 meters, the drone dropped a 100-kilogram* drone that followed a laser beam fired by another drone and flew towards the Izumo's first chimney.

At the same time, Nagara and all the members of the Qifeng were busy catching turtles in the urn, sometimes dropping bombs in the subjective guessing area, sometimes cruising and observing, and everyone was lying on the side of the ship, searching for no oil on the surface of the sea or other signs of sinking enemy boats.

The battle alarm on the Izumo Class A was still ringing violently, and Qiyun and Nagara 7788 in the distance dropped a total of 40 deep bombs in a sea area of several square kilometers, and they didn't know what they hit. In fact, it was the first time that the Japanese Navy had experienced a real anti-submarine battle, and they had collected a lot of examples from the Allies (the Germans could only provide experience in submarine attacks) and used them to conduct reverse research on anti-submarine warfare, but they had no extra experience other than exercises.

* Plunged headlong into the No. 1 chimney, smashed through the mesh fence at once, and plunged downward.

Cheng Dayang can see through the drone video that at the moment of the explosion, the 12 exhaust pipes around the chimney spewed black smoke at the same time, which shows that the ventilation equipment was destroyed, which is the effect he wants.

After the explosion, the original No. 1 chimney was gone, leaving only a large black hole with faint flames scurrying out from below, and the other two chimneys were no longer smoking.

"Captain, keep dropping bombs?"

"Wait, wait 20 seconds, let people gather before they start."

He expected that an explosion of this magnitude would not cause the Japanese to abandon ship, and if nothing else, they would give the order to rescue Izumo, so that the man would return to the center and hit at the same time, and at the same time open all the passages, which would be a good opportunity for him to strike.

As expected, the Izumo was suddenly attacked by an inexplicable attack, but there was no panic at all, and the captain immediately requested an "emergency response" through the broadcast system when the damage was unknown.

This is, after all, a ship that has seen the world, and everyone is well aware of their duty at such times, and the combat posts continue to calmly monitor the sea (no one knows that the attack is coming from the air), while the rest of the posts quickly organize themselves and concentrate on the blast area, where they must use hoses or other means as quickly as possible to prevent the worst-case scenario from spreading to the ammunition depot.

The sailors shouted and ran in the smoky corridors, looking at death as if they were returning to the Showa 11, the first time the ship was hit by a suicide plane of the Chinese Air Force, and that emergency response played a key role in reversing the occupation, and when the Izumo, which was boasted by Chinese newspapers to have sunk, reappeared in the Huangpu River, the arrogance of the Chinese army was completely knocked out.

The experience of history has proved many times that as long as we work together and the gods support us, no power can sink this ship.

A cloudburst bomb fell silently from the sky. It fell directly through the huge hole below, through the broken boiler, and into the least lethal area of the warship, the coal storage tank.

The orange-red flames instantly engulfed the surrounding sailors who were struggling to extinguish the fire, and then the low-speed flames extended along all possible passages to various areas of the warship.

Cheng Dayang could see flames coming out of the top exhaust pipe and the rest of the chimneys, the top of the turret, and even the gangships close to the waterline, and he knew that this must be a full internal burn.

Izumo, who has been constantly changing course, suddenly stops and brakes. It was slowly engulfed in fire like a coffin that smoked everywhere, and there was not a single living person walking around the deck. No one knew what the effect of the attack would be, only that the ship had stopped all its previous struggles and floated quietly as if it were dead.

Everything was frozen in motion, except for the flames and faint smoke.

Suddenly, there was another flash of fire, and the 203-mm twin guns* on the bow of the ship flew up and then smashed down. Shu Ping's prediction of detonating the ammunition depot under the main gun loafer with a high probability obviously happened.
