"Major General, you find an unknown fleet ahead, and it may be the Chinese fleet." A Japanese lieutenant hurried over to report.

"Baga! When will China have a fleet?"

Upon hearing this, Masato Kimura scolded. The Japanese lieutenant who came to report it muttered to himself that there was indeed a fleet, but the Japanese lieutenant could only lower his head and dared not let out any more.

Not long after, a Japanese captain came over and reported loudly: "Major General, you have already investigated clearly. It is not a Chinese fleet in the distance, but an American transport fleet, and the destination may be Ningbo."

Masashiki Kimura raised his hand and slapped the Japanese officer who had just come to report the situation. The poor Japanese lieutenant came to report the first time, hoping to please Masashiki Kimura and leave a good impression, but unexpectedly he was slapped.

After slapping this, Masato Kimura's face relaxed slightly. It was just an American transport fleet, so there was nothing to worry about.

"Major General, this is the second time we have discovered the American fleet. These damn Americans always transport things to Ningbo, providing a lot of resources for the development of the newly formed 6th Army. Whether we sink these transport ships."

The Japanese have obtained preliminary information. A number of factories have been built in the jurisdiction of the newly formed 6th Army, which can produce a large number of weapons and equipment. The Japanese are so angry that they hate these American fleets.

Masashi Kimura frowned and thought for a while, "Let's lean over and scare these Americans, and aim our muzzles at these American ships."

With Masato Kimura's order, the warship of the little Japanese leaned towards the American fleet, Masato Kimura was ready to scare these Americans. Then he fled here. Masato Kimura believed that even if the newly formed 6th Army discovered his whereabouts, even if he had to send a motive group to deal with him, it would not be so fast.

The little Japanese fleet was not far from this American transport fleet, and the two sides were traveling face to face, and the distance between the two sides quickly narrowed.

American fleet.

On the largest cargo ship, inside the captain's room, the middle-aged captain had received a report. A fleet of little Japanese was heading towards him.

The middle-aged captain who was smoking had a serious face and swung his cigarette butts hard, picked up one of his old monocular telescopes and looked into the distance. Even if he had only the naked eye, he could see the little Japanese warships sailing by.

The help of telescopes made it clearer. The middle-aged captain saw that the cannons on the Japanese warships were facing him, as if there were signs of firing at him.

"Hurry up and show your identity. Tell those Japanese shorts that we are the American fleet." No one was uncomfortable when they were aimed at by a cannon from little Japan, and the middle-aged captain was also unhappy.

On the heavy cruiser of the "Ancient Eagle", Masato Kimura held a telescope and looked at the American fleet in the distance. Seeing that the American ship was aiming at his cannons, the American ship was facing his identity, a smile appeared on Masato Kimura's face, which seemed to be very refreshing.

"Yoxi! Major General, are we going to fire a few shots? Scare these Americans?" A Japanese colonel next to him looked proud.

Masato Kimura shook his head. Masato Kimura knew that if he ordered the firing, it would probably turn into a diplomatic dispute, and Americans would definitely cause trouble for themselves through diplomatic channels.

Neither side noticed that in the sea water dozens of meters deep below the Japanese fleet, several submarines were sailing quietly and slowly.

This is not a submarine from the little Japanese, but a submarine from the newly formed 6th Army.

The small Japanese fleet led by the heavy cruiser "Aunt Eagle" did not have a submarine, and the newly formed 6th Army submarines under the water did not find the small Japanese submarines.

The naval forces of the newly formed 6th Army have been equipped with a submarine force, and the number of submarines has reached the scale of twelve. With the "Nuwa" system in hand, as long as there is enough merit value, it is not a problem to quickly equip a large-scale submarine force.

The soldiers of this submarine force have been undergoing training for several months, and what they lack is only practice. Each submarine has at least two or three professional command talents exchanged for the "Nuwa" system, commanding the soldiers to train and commanding the soldiers to fight.

All of these twelve submarines are German U submarines.

German U submarines were famous in later World War II. The submarine model exchanged by Ye Feng was naturally the first choice for German U submarines, and they are relatively advanced German VII U submarines.

This offensive submarine was the main submarine of the German submarine force in World War II in later generations, and was also the most important submarine in World War II. The boat was 67.1 meters long, with 44 to 52 crew members, a diving depth of 220 meters, 5 torpedo tubes (4 boat heads and 1 boat tail), and a total of 14 torpedoes. The maximum speed on the water surface is 17.7 knots, and the maximum speed underwater is 7.6 knots. The diving speed is very fast and can disappear from the water surface in 20 seconds.

The German VII U-shaped submarine is constructed with a pressure-resistant hull. The hull is made of slender steel cylinders and is equipped with waterproof facilities. The outer side of the pressure-resistant hull is equipped with a Ballast groove and a seawater shutter is located below.

When the air is charged into the tank, the submarine's buoyancy increases and the submarine will float. If the seawater valve and air valve are opened, the seawater will enter the tank, the air is squeezed out, and the submarine can dive.

The fuel bank located outside the hull has a clever structure, which will neither cause unnecessary buoyancy due to the consumption of fuel, nor will it collapse due to excessive pressure during submarine. U boats use two propulsion devices.

Two diesel engines are used when sailing on water at high speed, while underwater use electric motors driven by secondary batteries. The secondary battery weighs several tons and has a charging time of 3 hours. It can enable the submarine to reach a speed of 8-17 knots in the water. If the cruise speed is used, the U-boat can continuously submarine for 24 hours and a range of 100 kilometers.

The German VII U-shaped submarine has good underwater handling performance, with a floating speed of 16-18 knots per hour, and can quickly dive into the water within 20 seconds. Its endurance is 11,500 kilometers, and after improvement, it can reach 16,100 kilometers.

Six U-shaped submarines were quietly suspended in the sea water dozens of meters deep, moving slowly, with very small sounds and the electric motors were not loud.

"Tell me the order to prepare for battle, launch torpedoes, and sink these warships from Japan."

The commanders of these submarines issued combat orders, and the submarines began to open their torpedo launch tubes, and the sound of sea water pouring water.

In the submarine, the confined space is very quiet, and the soldiers are all in their place and are fully focused. This is the first actual combat for the soldiers, and no one dares to be careless.

On the sea.

On the heavy cruiser of the "Aunt Eagle", several Japanese sonar soldiers were still following the convention and monitoring the movements under the water as usual. From the heart, they thought that the Chinese army could not have warships, and even more impossible to have submarines. These Japanese sonar soldiers looked leisurely and hardly took it seriously, and even two people were talking and laughing.

A stingy-faced Japanese sonar soldier seemed to be different from others. He was carefully monitoring the movements on the sea. Seeing this, a short sonar soldier next to him smiled and said, "Noda, do you want to hear the movements of whales giving birth to cubs under the water? Haha..."

The other Japanese sonar soldiers also burst into laughter. One of them, who seemed to be thirty years old, reminded with a smile: "Noda, there are no submarines in this area, but there may be a few whales."

The sonar soldier with a faced face seemed to be more dedicated. He ignored the ridicule of the people beside him and listened carefully. Not long after, the face of the face seemed to change. There seemed to be a sound of torpedo launching tubes pouring into water under the water.

"No, there seems to be a submarine underwater!!!"

"Ha ha……"

The other Japanese laughed even louder, but unexpectedly, Mabang actually said that there was a submarine underwater. Looking at Mabang's serious look, two Japanese laughed even louder.

Seeing that everyone didn't believe it at all, he looked anxious and shouted loudly: "There is really a sound of torpedo tubes pouring into water under the water. Really, please believe me."

Looking at the face of the thirty-something, the Japanese man in his thirties, who seemed to be more experienced, shook his head while personally starting to monitor the movements under the water.

Under the water, there seemed to be a sound of torpedo tubes pouring water. As a veteran of the Japanese, this old Japanese man in his thirties was quite experienced. It was definitely the sound of torpedo tubes pouring water just now.

However, the sound seemed to be a flash in the pan and disappeared quickly, and then there was noisy sound under the water. At this time, the submarines under the water were ready to launch torpedoes.

"Baga, there is really a submarine. It was clearly the sound of torpedo launch tubes pouring water just now." The old Japanese man in his thirties shouted.

Seeing this, the smiles on the faces of several Japanese Japanese who were laughing suddenly froze, and they looked at the old Japanese Japanese in disbelief.

Just a few seconds later, all the Japanese reacted and suddenly became in chaos. The news of a submarine under the water soon reached the Japanese Major General Kimura Masatoshi.

When a submarine is most easily discovered, it is when the torpedo tube is flooded. This inevitable sound of flooding can often easily expose itself.

After receiving the report from a Japanese Major, Masato Kimura's face was so gloomy that he could almost pinch out the water. Unexpectedly, there was a submarine under the seemingly calm sea.

Which country's submarine is this? American? British? Or Chinese?

Thinking of the Chinese army's submarine, Masashi Kimura became nervous. If it were a Chinese army's submarine, it would definitely deal with him. So Masashi Kimura shouted, "Drive deep water bombs quickly, drop deep water bombs quickly."
