Take Taobao to fight against Japan

"Nani? There are a large number of torpedoes approaching us at high speed? Are you all idiots? Why haven't you noticed the situation?"

The devil's captain Jun Matsuyama frowned immediately, and the smile on his face froze instantly. He never dreamed that there were actually submarine troops ambushing in the waters of Madaban Bay.

"Bageya Road! Hurry up and dodge!"

"Hurry up! Report to the Commander of the Fleet that the submarine brigade has encountered an enemy submarine raid!"

"Hurry up! Search for the specific location of the enemy submarine immediately!"

After a short shock, Jun Matsuyama issued a series of orders again and again!

"Hayi! Your Excellency Major, we are already taking emergency measures!"

In fact, there is no need for the old devil to brag, the devil sailors with rich combat experience have already become flustered as soon as they received the police report.

On the deck of the Yamato-class battleship.

While Ren Takenaka, commander of the Devils Fleet, was standing still to watch, the Communications Officer of the Devils ran over anxiously: "Report to Your Excellency, Commander, it's bad, the submarine brigade was attacked by an enemy submarine!"

"Ba Ga! Sure enough, there is an ambush!"

Rien Takenaka raised her mustache, and then said in a deep voice: "Order all the destroyers to speed up to support, and we must kill all these hateful British guys!"

In order to avoid being missed by the Devils Navy, the submarine force of the Huben Army has always been developing in secret, and the scope of activities is limited to the submarine base and the coastal defense line.

So Japan, so far, knows that the Huben Navy has only a small number of small-tonnage surface ships, and has no idea that Yang Fan already has a submarine force of nearly [-] ships.

"Hay!"

The devil's communication staff immediately took the order and left.

Destroyers are equipped with various weapons such as air defense, anti-submarine, and sea-facing. They can not only serve as offensive assault missions in naval fleet formations, but also undertake air defense and anti-submarine escort tasks for combat formations. They can also serve as support in landing and anti-landing operations. troops.

Destroyers are relatively fast, and the torpedoes of the current era have no guidance function, so destroyers can generally avoid them.

In the current era, submarines have no missiles and only torpedoes. If they want to attack targets on the water, they must surface to attack, so that they can be easily spotted by destroyers.

Destroyers are faster than submarines, and have rough skin and thick flesh. Even if a submarine is hit by two torpedoes, it will not sink, but it is hard to say for a submarine.

The range of the naval gun is outside the boat gun, and its depth charges are the nemesis of the submarine.

Therefore, in the current era, destroyers have a crushing advantage over submarines, and they are like natural enemies. Submarines will never attack destroyers unless it is absolutely necessary. The targets of their attacks are generally oil tankers, transport ships, not destroyers.

Yang Fan is also very clear about this situation. A single submarine force cannot face the tough devils' naval fleet. The main purpose of ordering the navy submarine force to participate in the battle this time is to train troops.

"Boom! Boom! Boom!"

As soon as the devil's communications officer walked away, three waves exploded on the sea more than ten kilometers ahead, and the dull explosion sound quickly reached Ripple's ears.

"Reporting, Commander, three of our submarines were blown up, I-3, I-4, and I-52 were blown up, Major Matsuyama and 188 imperial soldiers! The enemy submarine force is heading towards the coastline quick escape"

It didn't take long for the battle damage to be counted.

"Baga! Die, die! Damn the British, everyone must die!"

Ren Takenaka was so angry that he was so careful that he got the point. Before he officially joined the battle, three submarines were blown up.

Although these three submarines are all old models more than ten years ago, their cost is not cheap at all. The cost of each submarine is as high as 1553 million yen, equivalent to more than 700 million US dollars in those years!

Thinking of this, Ren Takenaka was really desperate, and immediately roared viciously: "Hurry up, the destroyer formation pursues at full speed, and we must kill all these damn British guys!"

"Great job! The 24 torpedo rounds were not in vain! Continue to speed up and return to the voyage, and immediately send power to the coastal defense and air forces, and ask for fire support!"

Liu Qiang was well aware of the power of it, and returned immediately after launching two rounds of torpedoes in a row, not daring to stay where he was.

It was not until 2 minutes later that the results of the battle were confirmed through sonar. This time, three devil submarines were killed, which was considered a small profit.

According to the previous combat plan, the submarine force was lurking in the offshore area, and only took advantage of the troubled waters to take advantage of the troubled waters after the Devils' fleet fought with the coastline defense forces and the air force bomber fleet.

But the plan is not as fast as the change. The Devils Navy is really cautious enough to not give the Huben Submarine Detachment a chance to make a big deal.

"Baga! Drop the depth charges quickly, and we must not let these damn Brits escape!"

After a fierce pursuit by the 6 Devil destroyers, they finally caught up with the Huben submarine detachment that was retreating at full speed. Without any hesitation, the Devil destroyers began to output crazily!

Chapter 1058

Liu Qiang led the Huben Submarine Detachment to preemptively kill 3 Japanese submarines. The commander of the Devils Navy Task Force Commander Takenaka Ren became angry and sent all the destroyers to hunt down the Huben Submarine Detachment.

thump!thump!

After chasing for more than ten kilometers, the Devil destroyer finally caught the target. After setting the delay fuze, the Devil sailors began to push depth charges weighing more than 200 kilograms off the deck.

Depth charges have always been the standard weapon on anti-submarine ships in various countries. They are powerful, easy to use, and very popular.

The depth charge does not need to hit the submarine directly, the change in water pressure caused by the explosion is enough to tear the hull of the submarine.

Therefore, depth charges do not need to use trigger fuzes, but use delay or pressure fuzes, which need to be detonated at a fixed depth.

It's just that although depth charges are powerful in water, they can be as powerful as torpedoes destroying the keel of a ship.However, the shock wave decays quickly in the water, and the explosion radius is not large. For example, the D-type depth bombs widely used by the British army are only about 22 meters.

However, a deep bomb can seriously injure a submarine within 20 meters, and it needs to be destroyed within 10 meters, so the requirements for the timing and distance of the explosion are very high.

In the current era, the sonar system on destroyers is still very backward, and the sonar operation has to be discerned by the human ear.

It is well known that sound waves travel very fast in water, about 1500 m/s.

When the destroyer is less than 200 meters away from the submarine, the pulse wave emitted by the sonar is extremely close to the echo, which exceeds the resolution limit of the human ear, making the two "bang" sounds merge into one, and the submarine disappears.

This leads to very inaccurate depth parameters, and the error of the depth-fixed fuze is very large when the depth charge is thrown, and the submarine can escape many attacks by diving in time.

At the same time, the sonar has a blind spot directly in front of the bow, and there is a minimum detection distance, and the downtilt angle of the sonar beam is limited, so that the destroyer cannot be found when the submarine passes under the beam.

Therefore, anti-submarine ships can only blindly drop bombs on the expected waypoints, knowing nothing about the movements of underwater submarines, and the accuracy is poor, with a hit rate of only 3%.

Therefore, in World War II movies, there are often scenes where destroyers throw a lot of depth charges and work for hours, but the submarine still staggers out of the sky.

The reality is true. Most submarines are destroyed by the cumulative damage of long-term intensive firepower, and not many are sunk at one time.

For example, in April 1945, the German submarine U-4 survived the indiscriminate bombing of 427 depth bombs.

This time, the red-eyed Devil destroyer could only bomb blindly with depth charges in this way, dropping sixty or seventy depth charges at once, and carried out a wide-scale bombing.

Boom boom boom, after a while, huge waves churned violently, and the sound of dull explosions was endless.

But fortunately, although the devil's operation was as fierce as a tiger, the final record can only be nothing.

Under a burst of extreme operations, Liu Qiang and others escaped this wave of net bombing without any risk. Only two submarines were severely impacted, but that was all, and they did not lose their mobility. and fighting power.

"Report to Your Excellency, the enemy's 12 submarines are all alive and are continuing to flee towards the coastline!"

After all the depth charges exploded, the Devil's sonar operator immediately scanned to confirm the results, but sadly found that the 12 submarines were still alive and kicking.

"Baga! Not one of the damned British submarines was blown up? Hurry up and keep chasing, and drop all the depth charges this time!"

The commander of the Devil Destroyer Fleet, Yoki Iida, screamed angrily, this wave of operations was too embarrassing.

At this time, Koiwai, a devil's communication staff officer, stepped forward and politely persuaded: "Iida-kun, we are already too far ahead, and we have already entered the range of the Huaxia Coastal Defense Artillery. It may be dangerous to continue chasing!"

"Mr. Xiaoyan, as an imperial soldier, how can you be greedy for life and afraid of death?"

Iida Yanghui's eyes were already red, how could he let the fat in his mouth fly away like this? After glaring at Koiwai, he roared: "Immediately execute the order, and all destroyers continue to pursue! We must not let the imperial navy warriors sacrifice in vain ! Hurry up!"

In addition to being eager to make contributions, Iida Yanghui is not completely mindless looking for death, but has something to rely on.

Because although it has entered the effective range of the coastal defense artillery, the destroyer is fast and the target is small. As long as it is not very unlucky and back, it is difficult for the coastal defense artillery to hit the target accurately under normal circumstances!

"Hay!"

Xiaoijing, the devil's communication staff officer, didn't dare to continue to confront him, so he hurriedly led away.

"You're so arrogant, you dare to continue chasing after we get to our territory! Give me an order, aim and shoot! All artillery positions open fire immediately, and I overthrow all these **** ships!"

Ou Hao, the commander of the Tiger's Coastal Defense Force, has been observing the approaching Devil fleet. After seeing the Devil's six destroyers breaking into the range of the coastal defense guns, he gave the order to fire at all without hesitation.

In order to prevent the Japanese naval fleet from directly attacking Huanglong and just landed around Yangon, Yang Fan spared no effort to strengthen military defenses on the coastline around Yangon after entering Myanmar, and built a complete port defense system.

There are 88mm anti-aircraft guns, 155mm secondary guns, 280mm and 305mm coastal defense main guns. The forts can support each other or land firepower, and can also defend against the Japanese navy and air force.

In addition, there are dozens of coastal defense torpedo launchers. If the Japanese navy forces a landing or approaches and bombards them, it will definitely surprise the Devils fleet.

"Roger that!"

"understand!"

"Ready! Fire!"

More than 30 coastal defense guns of large and small calibers roared all day, and the shells drew white bullet marks in the sky.

Boom boom boom, a moment later, huge waves burst into the sky on the sea surface of Madaban Bay.

Especially the 305mm howitzer, the waves blasted are simply overwhelming, and the sound waves go straight to the sky, even ten kilometers away, it can also be deafening.

"idiot!"

"Die, die!"

But unfortunately, this round of concentrated fire attack did not directly hit the devil's ship, but it caused great panic to the six devil destroyers rushing to the front!

"Baga! How can the coastal defense artillery of the Chinese army be so many and so powerful!"

A 305mm heavy gun landed on the sea less than 30 meters behind the destroyer, blasting a huge wave as high as more than 20 meters.

A huge sound wave hit, Iida Yanghui was shaken so badly that his eardrums hurt and his head buzzed.

Fortunately, this is at sea, and the old devil is standing on the destroyer several meters above the water, otherwise, he would be dead or maimed!

Even so, Iida Yanghui was also startled into a cold sweat by the passing shot.

Although coastal defense guns cannot be like torpedoes, as long as they hit the hull, small and medium-sized ships like destroyers can shoot a child with one shot.

But as long as it is serious, it will definitely be fatal or injured, and its lethality cannot be underestimated.

Chapter 1059

"Hurry up! Drop the depth charges immediately!"

Although he was terribly frightened, he had no choice but to shoot. Iida Yanghui really had no face to keep his words like this, so he had to hang on for a while, at least he had to throw the bomb, right?

"Hay!"

The devil sailors also knew that it was not suitable to stay here for a long time, so they didn't care too much after getting the order, and pushed the depth charges down the slide with all their might.

At this time, the war had already begun, and there were noisy explosions and waves crashing everywhere, and the Devils' sonar officers could no longer track the sneaking submarine troops.

The devil sailors could only make rough estimates, and kept pushing depth charges weighing more than 200 kilograms into the sea on the destroyer's forward route.

thump!thump!

Depth charges fell into the sea one after another, splashing small waves.

After a while, there were dull and loud noises, and then I saw waves splashing into the sky on the sea.

This wave of devils was basically blind bombing, but it caused a lot of trouble for the Huaxia Huben Submarine Detachment. Bombs exploded in the sea, causing waves of extremely powerful overpressure shock waves.

Several submarines were shaken violently, and many Huben sailors were caught off guard and had their heads broken. Some even broke their bones and were seriously injured, and the hull also suffered great damage.

"Damn it, these devil destroyers are never finished!"

The No. 1 submarine where Liu Qiang was located was also shaken severely, and gradually stabilized after shaking violently for a while. Fortunately, although this round was more dangerous than the previous round, it survived anyway.

Captain Luo Faren said with a dark face: "The military seat is too aggrieved to be beaten passively like this, so why don't we float up and fight with these bastards!"

Since there are no torpedoes launched vertically in the current era, there are no missiles launched in the water, and submarines cannot face up. Therefore, if a submarine wants to kill a surface ship, it has to surface to launch a torpedo!

But it is obvious that it will not work in broad daylight. Not only is the coastal defense turret firing at full strength, it is easy to be accidentally injured, and the naval guns of the Devil Fleet are not vegetarian.

"It's not too late for a gentleman to take revenge for ten years, what are you in a hurry for?"

Liu Qiang glared at him fiercely, he didn't want to be happy with his enmity, but as the leader of the Huben Navy, he must never act on his will.

"I guess the depth charges of the devil destroyer should be exhausted, and our crisis should be temporarily lifted! Now we don't need to fight the devil!"

After a pause, Liu Qiang said in a deep voice: "Pass my order, the submarine detachment will continue to retreat to the naval base, and immediately check the hull damage and casualties."

"fire!"

"Hit me hard!"

"Aim at the point and kill all these dog days!"

Seeing that the Devil destroyer continued to chase and drop depth charges under artillery fire, Ou Hao was really anxious and angry, fearing that his submarine force would suffer a big loss, he repeatedly ordered the artillery to speed up the fire suppression.

In fact, without Ou Hao's urging, the coastal defense artillery artillerymen who had already suffocated all their energy, aimed at the devil's ship and fired wildly, carrying out round after round of heavy artillery fire.
