Dongxiang Guiichi is indeed fighting the idea of the North Sea Division fleet of the Ming Empire, and the idea he is fighting is still a very terrifying, and very bold crazy idea. Pen & Fun & Pavilion www.biquge.info

Because of Japan's limited national strength and the huge power gap with the Ming Empire in the production and procurement of weapons and equipment, the Japanese army has preferred the development and research of new weapons in the past year.

I have to admit that in Japan, a small island country, those aborigines who are cold in their bones actually have three points worth learning from. For example, this nation's ability to learn and learn from the strong, to integrate it into its own play and understanding, and to produce new understandings and results -- is really very terrifying and very powerful.

When the Ming Empire developed a new weapon, the tank, Japan immediately entered the mode of comprehensive exploration and research of new weapons. The Shenlong 1 fighter is an offshoot of this kind of exploration, and the secret weapon that the Japanese Navy has come up with to compete with the army for fighter projects is a new type of weapon that has been born for a long time but has not been taken seriously by the major naval powers.

The world's standard for measuring the combat effectiveness of the Navy is often the number of capital warships such as battleships and large-tonnage cruisers, so all countries are also developing the tonnage advantage of their navies and trying to maintain their position in this regard.

Traditional naval powers, such as the Ming Empire and the British Empire, both had large fleets of battleships and had cruiser fleets. In the construction of such warships, which cost people and money, it was obvious that the weak Japanese navy could not comprehensively strengthen and maintain an equal balance of power with the navy of the Ming Empire.

So, the clever Japanese Navy, with the support of Admiral Minister Takehiro Oda, began the research and development of the Qianlong project. As the name suggests, this time the Japanese Navy pressed its treasure on the unpopular submarine because of the shortage of materials.

With the recent progress in engine technology and the development of battery technology, the "Little Beanding" submarine, which was originally looked down upon by the navies of various countries, has been able to have a larger body and stronger firepower. Before the start of the war, the Japanese Navy secretly launched 13 brand-new submarines, which were named the "I-1" submarines.

The new submarine is designed with a complete modern submarine power system, using a diesel engine to provide surging power and charge the battery when sailing on the surface; When underwater, it is powered entirely by batteries, allowing the submarine to maintain a speed of between 3 and 4 knots.

Submarines of this type have an underwater displacement of more than 450 tons, a surface displacement of more than 300 tons, a length of more than 44 meters, and a width of more than 4 meters. With a height of 8.5 meters and a draft of 4 meters, the Japanese submarine is already very large in terms of size, compared to the experimental submarines equipped by various countries before.

The powertrain uses two six-cylinder diesel engines, as well as two electric engines. The maximum surface speed can be driven to about 12 knots, the endurance is as much as 3,800 nautical miles at the economic speed of 8 knots on the surface, and the submarine speed can be 40 nautical miles with 3 knots.

At the same time, the I-1 submarine is equipped with terrible weapons, equipped with three 533mm British Navy standard torpedo tubes in the bow, and five torpedoes can be reloaded and fired.

And this time, the biggest reason why Takaichi Togo was able to let the battleships of the Japanese Navy's Combined Fleet still cruise in the southern waters of the Korean Peninsula and did not go north to fight head-on with the prepared North Sea Division Fleet of the Ming Empire was that he sent his own killer submarine force.

The four I-1 submarines of the 2nd Guerrilla Fleet of the Japanese Navy were secretly deployed at the naval base in Nampo Harbor at the outbreak of war. One of the four submarines was under repair due to a malfunction, and one was on combat patrol in West Korea Bay, so only two were able to set sail immediately.

However, on the morning of December 10, the day after the Ming fleet shelled the Japanese coastal fortifications, the two submarines quietly sailed out of the military port. In the direction of the battleship fleet of the Ming Empire, he slowly approached the past.

But after all, they still missed the Ming fleet, because of the lack of communication, the two Japanese submarines who went north along the coastline missed the Ming Empire naval fleet, and drove all the way to the mouth of the Yalu River, and they were not able to find targets that could be attacked.

General Zhang Rude ordered the Ming Imperial fleet to turn around and return home, so that this fleet was lucky to avoid the Japanese submarine that came to sneak attack, but on the way back, it happened to encounter the Japanese submarine patrolling the sea in a hurry.

"Udada-kun...... Discover the Ming Dog Fleet! Inside the dimly lit submarine, a non-commissioned officer on duty stood in the middle of the hunting sea breeze, lowered his binoculars, and shouted to the submarine captain Kosuke Utada, who was sitting against the iron railing and smoking.

On the distant sea level, because there were too many warships of the Ming Empire, the billowing black smoke obscured the sky and the sun, as if it wanted to block all the horizon as far as the eye could see. The unconscious Ming fleet was mighty and headed in the direction of the Japanese submarine.

"Good! His Majesty the Emperor is indeed blessed by Amaterasu! Kosuke Utada threw away the cigarette butt he was holding in his hand, and then picked up the binoculars to look at the black smoke on the other side. In the eyepieces of the telescope, those huge ships were still just small black dots.

"Dive! Get ready for battle! Fast! Kosuke Utada put down the binoculars and ordered loudly to the sergeant beside him: "Open the valve and keep the ship at periscope height, quick!" Fast! ”

Following his order, the I-1 submarine, numbered No. 108, began to dive, and it took less than one minute for its entire body to dive into the biting cold waters of West Korea Bay, leaving only a periscope like a tube, still exposed on the water.

"Adjust course! We're going to the flanks of this fleet...... These damn Ming dog battleships, let's try your Uncle Utada's torpedoes! With his eyes on the periscope, Kosuke Utada muttered in his mouth as he gave the order to adjust.

This small warship with a displacement of 450 tons was just like a mosquito staring at a huge rhinoceros on the route of the North Sea Division Fleet of the Ming Empire. The rhinoceros unconsciously continued to walk the way it was going, but the mosquito had to find a way to extract a tube of bright red blood from the rhinoceros's body. (To be continued.) )
