If it weren't for the stubborn and strong domestic conservative forces, the Japanese Empire in the Meiji Taisho era almost turned to **** several times.

The Japanese Navy is supposed to be the first group of Japanese people to see the world clearly, but in fact, only a few have actually seen foreign customs, and only a few qualified naval officers have seen it.

Not every Japanese naval officer has the conditions to go abroad for inspection, for example, Kijima Nakasa has never gone abroad to study abroad, his graduation grades belong to the middle and lower, and he ranks 62nd among the 95 graduates in the class, and he is not an elite student, let alone get the "short sword given by the emperor" (that is a prize that can only be obtained by the students who rank first and second in the graduation grades of the whole grade).

Unless a graduate with ordinary grades like him has the opportunity to enter the Naval University for further study, he will wait for the grassroots troops to slowly get up. It took 24 years for Guijima Moriji Nakasa to become the commander of a diving detachment.

To say that there are few graduates in this period of Guijima who stand out, the best among the classmates is Takeji Osa, who is currently serving as a naval staff officer in the base camp of the military command department, and in history he also served as the fourth captain of the battleship [Yamato] in four or four years, and his position before retirement was the director of the naval personnel bureau, and the final military rank was rear admiral of the Imperial Navy.

Speaking of which, this Ono Osa graduation score is only a little better than that of Guijima, ranking forty-two out of ninety-five, but the problem is that his father is the Japanese Navy Admiral (Marshal) Ijiin Goro, and after passing to Ono Yoshikata Navy Osa, he took the surname Ohno, a proper navy ***.

He may have been the first Japanese Navy soldier to be allowed to enter the main ocean-going submarine of the independent country, and it was not until 1942, when the I-30 under the command of Nobuo Endo Nakasa went to Germany, that the Japanese Navy first came into contact with the German diving unit.

"The device doesn't look much different from the sea." Guidao said to the flower house.

Both of them are experts who have served as submarine captains for a long time, and even if some of the equipment in the U-boat command tower is seen for the first time, they can guess the purpose of it.

The conning tower of the German U-boat and the command tower of the Japanese Navy submarine belong to two different styles in terms of design. The Japanese Navy obviously borrowed the design of the large cruiser artillery submarines equipped by France and Britain in the early days, such as the imposing Sukuf, the Japanese designers added some of their own changes, and the structure belongs to the large conning tower, which has the advantage of having enough space to place command, observation, combat and navigation equipment, and the disadvantage is of course that it is not conducive to concealment at sea, and it will increase a lot of resistance when diving.

The German submarine control tower is generally small in size, this is for the actual combat considerations, the imaginary enemy of the German submarine is the powerful Royal Navy, fighting with this enemy, concealment is the most important, and the small control tower is convenient for the submarine to dive urgently, and the underwater mobility of the submarine can also be taken into account.

Historically, the Germans had found in the middle of the war that their conning towers were designed to be too small to accommodate more anti-aircraft firepower, and as a result, the conning towers of German submarines immediately began to evolve to large-scale, not only renovating anti-aircraft fire platforms, but also erecting four anti-aircraft guns.

"It's an improvised sighting device." Robin said, pointing to the torpedo-aiming telescope mount in front of the fence.

"Oh," the two Japanese officers sighed, whether they understood it or not, it was always right to nod anyway.

"Look this way, two." The third value official said with the camera in his hand. The expressions of the two Japanese officers stiffened slightly, but the picture still looked quite harmonious.

"This will be a testament to the friendship between the German and Japanese navies." Robin explained that Guidao quickly gave a thumbs up to the camera after hearing this.

"Guys, please come down this way with me." Igor had already climbed out of the hatch and leaned out of the cabin halfway out.

"Thank you." Guidao bowed to Robin, and then followed Igor down the ladder into the shell cabin.

The enclosure compartment has a lot of combat command equipment, and in the past, when fighting underwater, the submarine commander would operate the attack periscope here and direct the submarine to launch an attack on hostile targets.

In later movies, submarine commanders are often seen in the main command cabin, holding a periscope in his hand, and launching a torpedo attack in a serious manner. Although it is technically possible to do this, under normal circumstances, the captain usually gives important attack orders in the attack command room of the enclosure cabin or the command module, which is very detailed in the German U-boat movie "Attack from the Sea". As for the Hollywood "U571", everyone should just take it as a lively look, don't take it as a historical fact.

The Germans did not give Kijima Nakasa time to stay in the enclosure compartment, he only saw a large number of small instruments of unknown names, and an attack periscope encased in a lifting shaft, all the covers on the observation ports were closed, and Kijima did not see the important firing calculations and parameter nameplates.

Of course, there are also such attack command compartments on Japanese submarines, and as mentioned earlier, the design of Japanese and German submarines originated from the Second Empire, and there are not many differences in the overall layout.

Guidao followed the vertical ladder and neatly descended to the main command cabin of the submarine. This can be regarded as the brain and heart of the U106, and almost all the valves and equipment related to submarine navigation are located in this cabin.

The helmsman of the submarine is generally divided into two people, one controls the bow and stern balance rudder of the longitudinal pitch of the submarine, and the other controls the stern rudder of the submarine's left and right steering. This set of control procedures is common to submarines all over the world, and even in the 21st century, in the era of nuclear submarines, there are still two helmsmen in the control seat of the submarine.

Kijima did not have much interest in the steering system of German submarines, and Japan considered itself not to lag behind any country in the world in this regard. The Japanese Navy really stole a lot of cutting-edge technology from the British Royal Navy in the twenties, because it had cooperated with Japan for many years, and there were many people in the British Royal Navy at that time who were full of favorability towards Japan, and many people felt that the Washington Treaty was unfair to Japan, and the British government should continue to support Japan to fight against the Russian giant bear in the north. Many people even spontaneously leaked the British Navy's secret technology to Japan. For example, the British Armstrong maneuver... Ahem... The design director of the shipyard, Dane Court, leaked the design drawings of the British battleship [Nelson] to the famous Japanese Navy designer Hiraga without authorization, and many of the advanced design concepts gave Hiraga a lot of inspiration, and finally were used in the design of the "Yamato".

After Guidao entered the command module, what he wanted to see most was the navigation instruments of the U106, because from the parameter settings of these instruments, a lot of confidential information about the submarine could be read.

You must know that all the instruments of the submarine are specially customized, as long as you look at the readings on the dial, you can accurately estimate the performance indicators of the ship. For example, the depth gauge of the submarine clearly indicates the diving range of the submarine and the maximum diving depth. These are the secrets of the submarine, which are absolutely not allowed to be released to the outside world, and even if the government needs to do so, it will only give a false data.

Guidao immediately found his target, because it was originally a necessary instrument for sailing, and the position of the arrangement was quite conspicuous, and the size was several laps larger than the other instruments.

"This—" Nakasa Kijima was a little dumbfounded. These dashboards were coated with a thick layer of unknown substance, and now they can't see anything clearly, but Guidao can't come forward and wipe them with his hands, otherwise it will be too explicit.
