"Nani?! The submarine ship of the independent country?" Nakasa Kishima was also surprised, because in his concept, this kind of thing was impossible.

Takashima Moriji Nakasa is not the kind of bureaucrat sitting in the rear office. He is a graduate of the 44th class of the Navy School. After graduation, he has been serving in the submarine force. He worked as a submarine captain for a full twelve years. After accumulating enough qualifications, he was promoted to the commander of the team by his superiors.

Guidao has served as captains on five submarines, one of which is the Yi60 under his feet. Although most of the crew members under his command had been retired at this time, Guidao is well aware of the performance of this ocean-going submarine.

The special structure of the submarine made it impossible for her to search for sea targets as easily as other surface ships. As we all know, the height of the submarine command tower is very low, which brings good concealment to her, but also reduces the distance for observation because the earth's surface has curvature.

Therefore, submarines must rely on other technical detection methods to find targets up and down the sea surface. The most commonly used equipment is an underwater listener, which can be regarded as a passive sonar in later generations. The listener will not actively emit sound waves, but will only passively receive the sound in the sea water. After strict training, the sounds made by the propeller and engine of the ship can be distinguished from the noise of a sea water. A skilled operator can even calculate the speed and approximate course of the other party based on the angle changes between the sound source and the boat.

However, this time the independent submarine floated to the surface at such a close distance from Yi No. 60, and the listener on Yi No. 60 did not notice any strangeness in advance. This is really an incredible thing.

"If the listener is not malfunctioning, it is the operator who is slacking off and dereliction of duty. This must be investigated." Guidao held the large telescope installed on the open platform on the back of the bridge and turned the lens to the German submarine in front of the side.

This twelve-centimeter binocular telescope produced by Japan Optical Industry Corporation (at the time of Mitsubishi Consortium and later Nikon) is considered to be the standard equipment of Japanese naval ships. The submarine is equipped with a specially customized waterproof model. In fact, a metal waterproof cover with rubber gasket is installed at the eyepiece position. It is usually flipped up above the lens barrel, put down before diving, and is fixed and sealed with large bolts. This is the original creation of Japanese submarines, so that when outsiders see the huge waterproof cover that is flipped up, they often mistakenly think it is a Japanese high-tech equipment.

At amplification of twenty times, the unique command tower of the German U-boat was as close as it was, and you could clearly see several German naval officers and soldiers watching their own side with telescopes.

"The commander may have been covered up by other noises." The flower house was thinking of explaining to his subordinates, but in the end he was severely scolded by his boss.

"Ma Lu! Flower House! You are also a qualified captain! Wouldn't you blush when you say such words?" Guida let go of his large glasses and handed them back to the original lookout soldiers.

"The submarine ship of the independent country is turning and approaching slowly." The lookout hand standing at the top of the bridge reported it in time, and then turned the attention of the two chief officials back to the German ship in front.

At this time, the entrance and exit hatches on the front and rear decks of u106 were all opened, and German sailors wearing yellow tropical uniforms were climbing onto the deck one after another.

"All of them are recorded. This is the main ocean submarine equipped by the Japanese Navy." Captain Robin put down his telescope and turned his face to the second-level official. The other party was holding an eight-mm film camera in his hand.

"Don't worry, captain." The official replied with a smile.

"It's such a big ship." Lieutenant Igor lit a cigarette and passed the lighter to the captain.

"From the data provided by the headquarters, she has more than 800 tons more than us, but after seeing the real ship, I feel that it is much worse than this. Look at the size of this thing." Robin was addicted to smoking by the deputy captain. He took out his cigarette box from his pocket and took out a cool mint cigarette from it.

"Captain, the deck is sorted out, can you start?" The sailor shouted at the command tower while standing on the front deck.

"Okay, let the guys be more energetic. Now they represent the German submarine force." Robin replied loudly while pulling the command tower enclosure.

"I understand, everyone will be here! Everyone is more energetic!" The sailor shouted loudly, and the star-worthy official on the bridge blew a long whistle. The sailors rushed to their respective battle positions on the deck. The artillery opened the cover, the machine gun was loaded, and the air defense rangefinder was installed on the support of the boat hull fence. In the blink of an eye, the deck became a serious look.

No. u106 slowly turned the bow and began to walk opposite No. 60. At this time, the distance between the two sides was only 800 meters, approaching the safe distance that usually meets at sea.

"Keep the route at one-third of the speed." Robin ordered to the microphone.

"It's the captain, one-third of the speed." The navigator replied loudly in the command cabin.

"Send a signal." Robin turned his face and ordered the signal soldiers.

"It's Morse Code." On the bridge of Yi No. 60, the flower room was carrying a telescope and translated.

"This ship is the Navy submersible ship U106 of the Great Single Will Imperial Empire"

"Oh, it turns out it's u106." A sigh also sounded on the front deck of yi 60.

The group of students from the Navy Diving School, led by the instructor, also ran to the deck to watch the fun, saying that they wanted to see the young military academy students at the market. In fact, the instructors led the team had never seen the German submarine ships.

"Note! Such an opportunity is rare. Everyone should observe carefully. I have seen it in the school's briefing. This is the ace submarine ship of the independent Navy." Captain Fujiki, the leader instructor, said to the students with a serious look on his face, making it seem like he had really seen the briefing.

"The submarine ships of the country seem to be preparing for war. Are they fighting with whom?" Staff Nomura also ran up to the command tower after hearing the news. The originally spacious bridge was now full of officers at all levels. The original sailors had all been driven to the deck.

"How is it possible? The war has ended long ago, Nomura. This should be just ordinary training. The spirit of the Imperial Navy that never forgets training is what the Imperial Navy needs to learn, so everyone should work harder, Huaya." Nakasa Kishima looked up at the Huaya Captain.

"Ha, I understand, Commander." Huafang was still very convinced of this senior who was seventh period earlier than him, although the military ranks of the two sides were only one level apart.

In fact, the so-called 28th diving team currently has only the submarine No. 60, the submarine of the so-called 28th diving team. The situation of the commander of the Guidao team can be said to be quite embarrassing.

The original 28th submersible team was composed of three submarines, with hull numbers of Yi 59, Yi 60 and Yi 63, all of which were Haida iiib-type ocean submarines, and it was worthy of its name. However, Yi 59 was affiliated with Wu Zhenshoufu in its organization, and it was placed in the reserve service for sealing after three years of launching. So the 28th submarine team had only two submarines left. Last year, Yi 60 sank Yi 63 again. In the end, Yukiji Nakasa Kishima became the commander of the submarine team with only one submarine under his command. If something happened to Yi 60, the team could basically be revoked.

"How should I answer the submarine ship of the country asks about my ship's identity, mission and destination?" said Staff Nomura.

"Reply to them, this ship is the Imperial Japanese Navy submarine No. 60, which is undergoing a long-distance navigation training mission, and its destination is the Bangkok Port in Siam." Guida ordered.

"Is this appropriate? Commander." Nomura asked.

"There is nothing to hide, and you think the independents will not be able to find out later?" Takashima was born in Kagoshima fisherman and has a very open-minded personality.

"The submarine ship of the Duguo replied, u106 expressed his greetings to our ship. The captain of the Duguo people asked if we could exchange some supplies with them?!" The flower room put down the telescope and looked at the people in the bridge with a look of surprise.
