I am Jiang Weiguo in World War II

One after another, so dark that it merged with the black lacquered submarine, slowly surfaced, keeping most of the hull below the water surface, only the conning tower exposed.

Undoubtedly, the captains who commanded these submarines were all experienced in actual combat and had excellent commanding skills. Under their dexterous command, the submarines quietly appeared in the waters near Midway Island, without disturbing the US troops on the island.

There are ten submarines in this batch. It can be seen from the outline that these ten submarines belong to the German U-type, but they are not combat submarines, but transport submarines.

After the hatches of the conning tower were opened one by one, teams of well-armed crew members filed out. Obviously, these crew members were not submarine soldiers. They were all strong, muscular, bright-eyed, and highly disciplined. There is a clear division of labor and each perform their duties with high efficiency. No one speaks, and they communicate with each other through gestures. It can be seen that these people are from the most powerful troops in the army, and the strangest thing is that these people are wearing They are all U.S. military uniforms, and they are holding U.S. military weapons. They even have yellow hair, blue eyes, and fair skin. They are all European and American Caucasians. Inside the American military uniforms of the soldiers, there are hidden armbands that clearly mark their true identities: the Chinese Navy's "Yasha" special forces.

"Take care, brothers! I wish you a successful mission! Return safely!" On each submarine, the submarine officer and the special forces officer solemnly exchanged military salutes.

"Wait for our good news!" The special forces members replied in fluent Chinese, calmly inflated the rubber raft, and paddled silently to Midway Island in the night on the rubber raft.

The heading of the fleet is 37 degrees, and the speed is about 18 knots. This time is the local time in Hawaii × month × day × hour × minute!”

……

In the Fleet Command Room of the aircraft carrier Nanjing, [-] or [-] staff officers are working intensely, meticulously, seriously, and rigorously. On the huge nautical chart, the distribution of the US fleet group around the Hawaiian Islands is constantly being supplemented. , improving and updating.

If the army wants to win a battle, in addition to competing in hard power, it also needs to compete in soft power. One of them is the commander's judgment and decision-making ability.

Many people think that the key to the victory or defeat of a war lies in whether the commander can "wave a goose feather fan and come up with a clever plan" like Zhuge Liang, and then be able to defeat the enemy.

In fact, to achieve this, a large number of excellent and experienced staff officers are needed, and it is definitely not possible to "strategize" with one person's mind.

In a battle, all aspects of information generated are very complicated. What should the staff officer do?It is to do our best to collect all kinds of battlefield information that can be collected, and then "purify, extract, and summarize" it, and report the correct and accurate information to the commander in the most concise language, so that the commander can base on these Battlefield information for judgment and decision-making.

It is conceivable that if the staff officers report wrong or long-winded or irrelevant information to the commander, the commander's judgment and decision-making ability will inevitably be greatly affected. The effect is very great.

Right now, this is what the staff officers are doing in the general command room of the Nanjing.

Land battles, sea battles, and air battles each have their own characteristics, and sea battles may be the one that tests mathematical ability the most.

If the Nanjing Fleet wants to win the battle, it must know where the U.S. fleet is and how it is distributed. At the same time, the U.S. warships are not fixed on the sea. How was it?Where was the U.S. fleet an hour ago, and where is the U.S. fleet an hour later?During this hour, did the course and speed of the US fleet change?If you can't find the target, just calculate it based on the course and speed of the target when it was found last time.Has the target discovered its own intentions, and then suddenly changed its course and speed?After all, the sea is a plane (of course it is not a real plane, but it can be regarded as a plane within a range of thousands of kilometers, ignoring the arc angle of the earth). The speed of the carrier aircraft... the combination of various factors is undoubtedly a complicated math problem.

"When I was in school, I often encountered a kind of math problem!" Ouyang Sihai stared at the nautical chart and said to Zhong Junchu, "How many meters are the distance between A and B? The car is moving, and the second car is driving towards the first car at a constant speed or some kind of acceleration or some kind of deceleration, and finally please calculate when the first car and the second car meet!" He laughed, "I looked down on this kind of math problem at the time, and thought it was very boring , has no practical significance.

Thinking about it now, how superficial it was at that time!Look, how many kilometers are there between our aircraft carrier and the U.S. aircraft carrier, where are the two sides, what speed and heading are they, and when will they meet? This fucking is exactly the same as that kind of math problem!It’s just that if you made a mistake at that time, you would only be scolded by the teacher, but now you will be bombed and torpedoed by the enemy, and the precious fleet entrusted to us by the country will be ruined!”

"Not only the data of the two fleets, but also the data of the carrier-based aircraft!" Zhong Junchu added, "There is no need for face-to-face battles between aircraft carriers, as long as they find the enemy fleet and dispatch carrier-based aircraft.

Then, when calculating, we must add many factors such as the speed and range of our carrier-based aircraft, the speed and range of US carrier-based aircraft, the fuel consumption of the aircraft, the fatigue of the pilot, the efficiency of the carrier-based aircraft taking off and landing, etc. .

This kind of math problem is much more difficult than the ideal state encountered in school!"

Yuan Fangqiao came over and said, "A total of 13 aircraft carriers have been deployed by the U.S. military on Oahu Island. Two of them (the Lexington and the Essex) were sunk by the defenders of Oahu Island. There are still 2 aircraft carriers that the U.S. military participated in. There are about 11 escorting aircraft carriers, 50 of which were successively sunk by the Oahu defenders, and there are still about 13 ships!" He pointed to the nautical chart, "The eleven regular aircraft carriers of the US military are the top priority. The defenders tried their best to cooperate with us. During the day, they dispatched planes to harass the U.S. troops to contain and attract the U.S. troops. At the same time, they also reconnaissance the U.S. troops. At night, they dispatched reconnaissance planes equipped with night vision goggles to continue reconnaissance of the U.S. troops, providing us with In addition, our navy currently has about 35 submarines operating in the waters of Hawaii, basically not attacking the US fleet, but quietly tracking, monitoring, and reconnaissance of the US fleet. Provides a steady stream of enemy information.

Of the 11 aircraft carriers of the U.S. military, 8 have confirmed their positions and 3 are uncertain. Although they are not perfect, they are enough for us to take the lead!" He smiled confidently, "In modern warfare, intelligence can be called The key to the decisive role, we are far inferior to the US military in strength, but we are in a great advantage in intelligence!"

Zhong Junchu nodded: "In order to storm Oahu, the U.S. military must deploy aircraft carriers in the waters around Oahu. They can't put the aircraft carriers far away from the battlefield, right? Because they have to be close, so This is one of our advantages!"

"Where is the land-based aviation force of the US military?" Ouyang Sihai asked.

Yuan Fangqiao thought for a while: "The U.S. military is indeed constructing field airports on Kauai, Maui, and Hawaii, and the U.S. military is completely mechanized, and the progress is quite fast. It was seriously damaged, and our army's special agents and special forces lurking on the three islands also continued to cooperate with the Oahu Air Force to continuously attack the U.S. airport.

Not only that, but the U.S. military is also very smart. On the one hand, they built an airport on the three islands half-truthfully. The carrier-based fighter jets are waiting for the Oahu defenders to come to the air strike.

In this way, the price paid by the Oahu defenders' air strikes on the U.S. military airports on the three islands was getting higher and higher, and it was obviously not worth the loss.

The defenders of Oahu have done their best, but it is only a matter of time before the US military has land-based aviation!"

"How early and late?" Ouyang Sihai asked.

Yuan Fangqiao calculated in his heart: "The elder is half a month, and the shorter is ten days!"

"Time is running out for us!" Ouyang Sihai nodded, the logic is ready-made: If the US land-based aviation can gain a firm foothold on the battlefield in Hawaii, the Nanjing Army on Oahu will be able to handle it, and they will be able to drill into the ground. You can take it easy, what about the Nanjing fleet on the sea?Where to drill? "Concealment is our greatest advantage!" Ouyang Sihai said, "What I am most worried about now is whether the little devil has tipped off the Yankees!"

"Probably not!" Zhong Junchu said, "Up to now, we have not been intercepted by the US military!"

Xu Zushan came over: "The arrow is on the string, we have to launch it, if we are paranoid at the last moment, it will be mediocre.

Don't think about it so much, I decided to hit the target in the first wave!" He clicked somewhere on the nautical chart with his finger.

Ouyang Sihai and the others looked at the nautical chart together.

At this time, the U.S. military has hundreds of ships and ships involved in the Hawaiian campaign. Such a large number of ships must not be concentrated in one place, but scattered around Oahu Island in a patchwork manner. The division of labor is clear and each performs its duties. Some are responsible for directly participating in the war or providing sea and air firepower for the U.S. military on the island; etc.

If you want to use an image metaphor, Oahu Island is like a magnet, attracting large and small U.S. warships in all directions, some close to some farther away, scattered into more than a dozen large and small "ship groups" .

The scattered array of the US fleet group is undoubtedly very suitable for the Nanjing fleet's surprise attack. At the same time, the Nanjing fleet's surprise attack can only be carried out once. After the surprise attack, the US military will know that the Nanjing fleet has touched itself side, it is impossible to raid a second time.

Therefore, the U.S. fleet is divided into more than ten "fleets", large and small, and the Nanjing fleet can only "eat once". Which one should it eat?

The four aircraft carriers of the Nanjing Army are equipped with a total of 296 carrier-based aircraft. The performance and pilots of the aircraft are world-class, but the number is really small. Considering that after the attack is launched, some carrier-based aircraft will be reserved for the self-defense and reconnaissance of the fleet. Therefore, the Nanjing fleet can dispatch about 250 carrier-based aircraft to participate in the first wave of attack, half of which are fighter jets, and half are dive bombers and torpedo attack aircraft. At the same time, the Oahu defenders will also dispatch land-based aircraft to assist their own fleet The number of carrier-based aircraft attacking the U.S. military together can exceed 300, totaling about 550.

——There is such an idea: after the carrier-based aircraft is dispatched, can the spare carrier-based aircraft be transferred from the transport ship to the aircraft carrier and then take off, thereby increasing the number of carrier-based aircraft?In actual combat, this method is difficult to work, because it is very time-consuming to transfer the spare carrier-based aircraft from the transport ship to the aircraft carrier, the efficiency of dispatching carrier-based aircraft is too low, and if the time is not grasped, the dispatched carrier-based aircraft will return to the voyage. If the flight deck of the aircraft carrier is occupied by spare carrier-based aircraft, the entire aircraft carrier will be in chaos, which will not only cause unnecessary losses, but also allow the enemy to take advantage of the battlefield where every second counts.

Since it can only be "eat once", some military officers advocate opening up and attacking four or more U.S. aircraft carriers at the same time. Killing the four U.S. aircraft carriers first in one go can greatly weaken the strength of the U.S. military. Narrowing the gap in the number of aircraft carriers between China and the United States is conducive to our own continued efforts, and can also play a "guaranteed" effect-the Nanjing Army has a total of 4 aircraft carriers. Even if an aircraft carrier is completely wiped out (or completely wiped out by the U.S. military, or completely wiped out by the Japanese army), it will still make money without losing money;

Other military officers advocated being cautious and only attacking two or three U.S. aircraft carriers at the same time, eating them as soon as they could be eaten, and giving up the attack immediately if the situation was not good, so as to preserve their strength to the greatest extent while achieving certain results. Next, the fleet will play hide-and-seek and guerrilla warfare with the U.S. military in the North Pacific Ocean. It can still play the role of containing the U.S. military and reinforcing the war on Oahu.

Xu Zushan, who had the decision-making power, finally made the final decision, delineating a seemingly simple goal: three US aircraft carriers.

"The latest information shows that about [-] nautical miles north-northwest of Oahu Island, there are three US aircraft carriers, all regular aircraft carriers, and several escort aircraft carriers.

Let's hit those three regular aircraft carriers!" Xu Zushan gave the order.

Yuan Fangqiao looked outside, the night was dim.

"We have now advanced to about 520 nautical miles (about 1000 kilometers) east-northwest of Hawaii. It has just entered the night, and the night will cover us for about 8 hours. In 8 hours, the fleet can continue to sail about 250 nautical miles. The distance between the enemy and our fleet It will be shortened to about 270 nautical miles (approximately equal to 500 kilometers) at dawn tomorrow. After taking off the carrier-based aircraft, the carrier-based aircraft can launch an attack on the US aircraft carrier after flying for an hour.

However, that will happen after 9 hours!" Yuan Fangqiao calculated, "9 hours, the variables are too big, what should we do if the number of scheduled strike targets suddenly increases?What if the planned targets suddenly decrease?The deployment of US aircraft carriers can undergo comprehensive changes within these 9 hours.

Junzao, everyone, when the Japanese raided the U.S. fleet, we are also raiding the U.S. fleet now. However, there is a big difference between the two raids. When the Japanese raided, the U.S. capital ships were all motionless in Pearl Harbor, and they were completely fixed targets. , we are going to make a surprise attack now, and the US warships are all in motion!"

"Yes, on the battlefield, the situation changes rapidly, let alone after one night!" Xu Zushan nodded approvingly, "However, there is no conclusion that one can draw a conclusion of victory through prediction and calculation before a battle is fought.

War itself is actually a kind of gamble. What we can do is to do our best to minimize the risk and maximize the chance of winning.

Alright, I'm going to take a nap first!" After speaking, he walked into the single room near the meeting room, and soon, his snoring came from the lounge.

Listening to Xu Zushan's snoring, the officers felt waves of psychological comfort.

The battle is imminent, if your commander shows negative expressions such as panic, restlessness, uncertainty, timidity, hesitation, etc., it will inevitably greatly affect the psychological state of his subordinates. Talking and laughing happily will inevitably make the subordinates feel a kind of spiritual support, so that they will be more calm and confident.

Later, everyone knew the truth: Xu Zushan didn't fall asleep at all in the lounge. He didn't feel sleepy and kept his eyes open, but in order to calm his mind, he deliberately snored intermittently and pretended to be asleep.

It is impossible for Xu Zushan and others to "not feel guilty".

Although the Chinese navy is not strong right now, it is very strong, because in the past four years of peaceful development and construction, the Chinese navy has had enough time, enough funds and resources to conduct high-intensity training, whether it is warships or people, All have been strengthened to the maximum extent. The latest weapons and equipment and machinery and equipment are constantly replaced on the warship, and the personnel are trained like a thousand times. For example, the pilots of aircraft carrier aircraft are completely devil training. First, it is not inferior to the Japanese naval pilots before the World War. Anyway, Jiang Weiguo has money and oil, so that the trained naval pilots are not only of high quality, but also in batches. The formerly trained pilots immediately fell into a situation of "shortage" after being killed or injured. Even ordinary sailors are well-trained.

It stands to reason that the Chinese navy is not a silver-colored pewter gun, and has all kinds of opportunities and favorable conditions. Senior military officers such as Xu Zushan should feel that they are "confident and sure to win." In this battle, Xu Zushan and others felt "not guilty" but abnormal.

Just like the Japanese, in order to attack Pearl Harbor, they carefully planned for a year, but when they were about to put it into action, Yamamoto 56 and others still felt guilty.

"Actually, we still have an imminent problem!" After watching Xu Zushan leave, Yuan Fangqiao looked at Ouyang Sihai and Zhong Junchu, "At the beginning of the war, we knew where the US fleet was, but the US military didn't know where our fleet was. However, after launching the first wave of strikes, it is impossible for our carrier-based aircraft to be wiped out. After the battle, the carrier-based aircraft will return to the aircraft carrier. The US carrier-based aircraft can completely follow our military carrier-based aircraft and find ours aircraft carrier fleet.

At that time, the enemy will know us and we will be equal, but the strength of the US military is much stronger than ours. We will not be able to wipe them out in the first wave of strikes. They will still have thousands of aircraft, enough to fight back. Blow us all to the bottom of the ocean.

An aircraft carrier-based aircraft can fly hundreds of kilometers an hour, an aircraft carrier can only run tens of kilometers an hour, and our aircraft carrier can't outrun the US carrier-based aircraft at all!"

Zhong Junchu nodded: "This is indeed a key issue.

After all, it is different for an aircraft carrier to launch a carrier-based aircraft and a rifle to shoot bullets. The bullets are disposable and do not need to be recycled, while the carrier-based aircraft needs to be recycled!"

Ouyang Sihai looked at Yuan Fangqiao and Zhong Junchu, and said disapprovingly: "Then I won't take it back!"

Yuan Fangqiao and Zhong Junchu stared at Ouyang Sihai together.

夏威夷当地时间4月30日，凌晨2时30分整，夏威夷西北偏东约330海里处。

The rapid knock on the door woke up Xu Zushan who was pretending to be asleep. He immediately jumped up and opened the door of the lounge. Ouyang Sihai stood outside the door, ignoring the salute, and handed over a document: "Junzuo, suddenly situation.

Sixteen minutes ago, the destroyer Yangzhou spotted and sank a non-our submarine of unknown nationality on the southern outskirts of the fleet's anti-submarine defense circle!"

Xu Zushan, who was not sleepy at first, was startled: "Why did it take 6 minutes to report?"

"Jun Zuo, have you forgotten? For the sake of concealment, our entire fleet is radio silent, and the radios on each ship must be strictly turned off. The communication between each ship can only be through signal lights, signal flags, and traffic boats.

After the Yangzhou sank the submarine, a speedboat was dispatched to the Nanjing and reported the incident!"

"How far was the Yangzhou from the main body of the fleet at that time?"

"About five nautical miles.

Junzuo, all accompanying cruisers and destroyers are equipped with the most technologically advanced air-to-air radar, sea-to-sea radar, and sonar detector jointly developed by China and Germany, which can scan underwater submarines within five nautical miles, so each escort All warships keep a distance of about five nautical miles from the aircraft carrier!"

"What's the weather like now?"

"Sunny day, bright moon and few stars!"

Xu Zushan felt a little nervous: "So, depending on the conditions, there is still a certain probability that the submarine will find our aircraft carrier?"

"This possibility cannot be ruled out!"

Xu Zushan tried his best to keep his sleep-deprived brain calm: "If that submarine had spotted our aircraft carrier and sent a signal to its headquarters before being sunk by the Yangzhou, then we would have been completely exposed. If not, we would have It will be exposed, because the submarine has lost radio contact with the headquarters, and its headquarters must have noticed the clues!"

Ouyang Sihai thought for a while: "Not necessarily.

After the submarine is dispatched, in order to maintain concealment, radio communication with the submarine base will not be carried out very frequently.

Optimistically, we still have some buffer time.

Two hours later, the attack will start, and the same sentence, the arrow is on the string, we have to launch!"

Xu Zushan thought for a while, then nodded: "Yes, the arrow is on the string, so I have to shoot it.

I was wondering, is that submarine American or Japanese? "

Ouyang Sihai said: "I hope it belongs to the Japanese!"
