Yamamoto Isoroku is the sixth son of the Nagaoka City samurai Takano family. Because Takano Sadakichi was 56 years old this year, he named his son "Takano Fifty-six".

He was trained in bushido and military affairs from an early age, and had a strong will and a competitive enterprising spirit. When Fifty-Six was 10 years old, his father slashed his legs 12 times with a katana (showing the ancestral perversion of the little devil), representing his official Yuan Uniform.

(Yuan costume, the little devil's men's coming-of-age ceremony.) The boy of the Xiwu family is considered an adult at the age of 12, and he must learn Wenwu to be a real man. The Chinese nation lacks a martial spirit, so it naturally becomes the sick man of East Asia, and it is not surprising that they are bullied. In 1916, after graduating from the Etajima Naval Academy, he was introduced by Viscount Makino Tadashi to the old Yamamoto family of the old Nagaoka Domain, and became the righteous son of Yamamoto with a sword, and changed his name from "Takano Fifty-six" to "Yamamoto Fifty-six".

In December 1924, Isoroku Yamamoto was appointed instructor and deputy chief of the Kasumigaura Air Force of the Japanese Navy. In order to circumvent the constraints of the Washington Naval Treaty, Yamamoto proposed a bold idea, which was subsequently put into practice.

The idea is that if the shipping companies of the little devils build new ships according to the parameters designed by the Admiralty, then the Admiralty subsidizes 45% of the shipbuilding costs (later increased to 65% by the Admiralty).

This workaround greatly stimulated the shipbuilding enthusiasm of the major shipping companies, and from 1925, the tonnage of the little devil's "civilian freighter" began to grow from 15,000 tons. Soon there were 50,000-ton oil tankers, 70,000-ton cruise ships, and they continued to rise.

By 1938, there were more than 740 cargo ships with a standard displacement of more than 20,000 tons. Among them, there are more than 260 large "civil cargo ships" with a standard displacement of more than 30,000 tons.

It is precisely because of Yamamoto Fifty-six's cunning and cunning that he completely bypassed the "Washington Naval Treaty", so that the development of the little devil's navy was not restricted in the slightest, but expanded infinitely.

In the four years before the outbreak of the Pacific War, the little devils "requisitioned all oil tankers and cruise ships by the state" and then converted them into aircraft carriers. Because these so-called freighters are simply the hulls of aircraft carriers, but they have not completed the final outfitting.

At the same time, in order to solve the problem of limited tonnage of warships, Yamamoto proposed the method of aviation operations. Through continuous efforts, Yamamoto Isoroku became the founder of the Japanese Devil Naval Aviation.

Yamamoto Fifty-six proposed to the deputy chief of the Military Command Department, Nobumasa Sueji: "The Imperial Navy, which was forced to accept the inferior proportions, could only deal a severe blow to the enemy by air attack at the very beginning of the battle against the superior American Navy. ”

In letters to his subordinates, Yamamoto said many times: "The day of war with Britain and the United States is not too far off, and the main problem to be solved before the war begins is how to make a leap forward in aviation, and this matter is the most urgent task at present." ”

To this end, he actively promoted technical cooperation with Germany, and also paid special visits to Ribbentrop and the commander of the German Navy, Erich Raeder.

With the direct participation of Yamamoto Isoroku, the Heinkel company transferred He70 dive bomber technology to Japan. Later, in the surprise attack on Pearl Harbor, the Type 99 shipboard critter that played an important role was developed on the basis of this technology.

The notorious Zero fighter was also the result of Yamamoto's efforts, and it was also the most successful example of his cooperation with Germany in military aviation.

Without the aluminum alloy technology provided by Germany, there could have been no success in the Zero War; In exchange, Yamamoto also fully disclosed to Germany the technology of his flagship, the aircraft carrier Akagi, which built the aircraft carrier Count Zeppelin.

In 1939, in order to form an alliance with Germany, Yamamoto Isoroku had been vague about it, and the War Department and the Navy were split. After that, the Japanese army officers of the Shaozhuang faction began to openly accuse a small number of pro-American factions, believing that their opposition to the senior officers of the Three Kingdoms Axis was "harming Japan's due interests."

In a spring exercise last year, in March 1940, a fleet of two aircraft carriers led by Rear Admiral Jizaburo Ozawa destroyed a fleet of two battleships and one heavy aircraft carrier under Yamamoto's command in one fell swoop, using intensive aircraft to assault in a concentrated manner.

When Yamamoto Fifty-six saw the result of his defeat by his subordinates, not only was he not unhappy, but he was extremely excited, and said to the chief of staff next to him, Major General Fukurushi, "Furu-kun, do you think you can use a plane to bomb Hawaii?" ”

From this time on, Yamamoto Isoroku has been planning how to perfectly raid the Americans' Pearl Harbor Pacific Fleet.

"It's a matter of the simplest strategy, but I didn't expect Sakagaki-kun to not know, it's a pity. It was precisely because of the preparation for war against the Americans that it was not possible to go around proclaiming an alliance with the German Empire. His Excellency Nagano had already emphasized when he commented on Bai Shujie just now, and the art of war of the Shina people said: 'Yes, but it can't.' ’”

In response to the criticism of his rival Seishiro Itagaki, Yamamoto Fifty-six said with disdain: "Didn't Sakagaki-kun think carefully about the issue of strategy? It is precisely because they are preparing to act against the Americans that they cannot expose their intentions, let alone talk about the alliance of the Axis powers. This is the most basic strategy of the art of war, do you need me to explain it? ”

"I personally agree with your analysis that it will give us about half a year to curb the influence of the Americans in the Pacific." Konoe Fumiro finally made a decision: "The Admiralty immediately began to formulate a detailed battle plan, and I will enter the palace tomorrow to report the results of today's research to His Majesty the Emperor." Once approved by His Majesty the Emperor, implement it immediately! ”

What strategic adjustments have been made to the base camp of the little devils, Bai Shujie doesn't know.

After returning from the Gwangju launch base, he has been wandering back and forth between the Weapons Research Institute, the Instrument Research Institute, the Engine Research Institute, and the Rocket Research Institute.

Over the next two months, the Rocket Research Institute and the Engine Research Institute jointly conducted 72 tests. At most, three tests a day were carried out to verify the following:

rocket engine power, 7 tests were carried out; Balance gyroscope test, carried out 3 times; The magnetic sensor entered the missile control system and three launch tests were carried out; Rocket fuel formula improvement, completed 11 this practical yàn; The radar beam sensor entered the missile control system and was tested 5 times; Adjusting the electronic computer, 33 of this real yàn were carried out.

On March 21, 1941, the first verification test was carried out on the 4-layer 36-tube "Flying Dragon Rocket Launcher". This was the last full launch test before the installation, so the strictest secrecy measures were taken, and the test site was in the ravine northwest of Ahufeiling.

The content includes the launch mode: single-tube launch, double-tube salvo; Ignition device: the tractor drives the generator to ignite and launch, and the backup battery ignites and launches (it is used after the towing vehicle fails or is destroyed).

The 36-tube rocket launcher that is going to be finalized today is called a "tube", that is, a launch canister, not an orbital launcher at the beginning.

Because Bai Shu found that there are many problems with the orbital launcher, especially during the journey, if the rocket is put on the orbit, it will not work at all. Wait until you reach the destination and then start planting rockets, so as to ensure the suddenness of the strike. In the end, Bai Shujie decided to do it in one step and directly use the launch canister structure.

The diameter of the projectile is 240 mm, the length of the projectile is 1.52 meters, the total weight of the rocket is 56 kg, the warhead charge is 32 kg, and the diameter of the launch canister is 410 mm.

The solid fuel of the engine is 11 years old, and finally the polysulfide rubber (including magnesium powder and anti-decomposition agent that increases the combustion value) "invented" by Bai Shujie is used, and the oxidant is perchlorate to make the combustion column.

The first type of carrier vehicle was a 10-wheeled truck specially made for the Pyongyang Tractor Plant, with a total combat weight of 12 tons. The speed of the bomb-carrying highway is 80 kilometers per hour, and the maximum mileage is 320 kilometers.

The second type of carrier vehicle, a tracked armored vehicle produced by the Pyongyang Tractor Plant, has a total combat weight of 24 tons. The speed on the road is 72 kilometers per hour, the off-road speed is 56 kilometers per hour, and the maximum mileage is 240 kilometers per hour.

Today's test is the two rocket launchers, a total of 72 rockets. The whole process took one day, and the technicians of the expert group and the observers of the artillery regiment made detailed records.

The results fully met Bai Shujie's requirements: the range was 16, 20, 24, and 28 kilometers (divided into four ranges according to the elevation angle of the launcher), and the launch time interval of the single tube was 1 second, and the launch time interval of the double tube was 3 seconds. There is no problem with the ignition of the on-board generator and the ignition of the backup battery.

The finalized production speed is fast, because Bai Shujie has already arranged the production of the carrier vehicle in advance, and the manufacture of rockets is not complicated.

After two months of overtime, 72 10-wheeled trucks and 72 armored vehicles have been installed in place, and the two artillery regiments originally planned by Bai Shujie have been completed.

According to Bai Shujie's order, the reserve of carrier vehicles still continues to be produced, and the rockets need to be further refined until the range reaches about 36 kilometers, and then the rockets can be stockpiled in large quantities.

As for the current two regiments, they will not be included in the establishment for the time being, and all of them will be directly under the headquarters, and the main purpose is to train new-type artillery.

Bai Shujie's "Second Artillery", which had been brewing for six years, finally surfaced, and there was no longer any need to use "wooden cannons" to fool ghosts. Zhao Jinxi, Gan Tong and others all said that he was a man of God and could predict the prophet.

At the same time, in accordance with Bai Shujie's order, the expert group began to develop a ship-based "Gaoping dual-purpose rocket launcher" capable of launching at a large elevation angle, with a diameter of 320 mm, a length of 2.4 meters, a launch weight of 3.2 tons, a warhead charge of 1.8 tons, a firing range of 40 kilometers, and a firing height of 12 kilometers.

Bai Shujie knew that missiles capable of precision strikes could not yet be developed and formulated. However, in order to cope with a large-scale war that may break out at any time, it is necessary to have a certain ability to cover and strike and ensure the safety of its own fleet.

The use of rocket artillery air defense is a workaround that Bai Shujie came up with. Because the planes of this era are not fast, the dense rain of bullets can make the enemy aircraft at a loss.

"You're finally back!" Zhao Jinxi saw Bai Shujie return to his war room, and immediately took a few telegrams and said: "On April 6, Germany attacked the Balkan Peninsula, and this has been said by you; On April 13, the Soviets went so far as to sign the "Soviet-Japanese Non-Aggression Pact" with the Japanese. On April 27, Germany occupied Athens and Greece fell. ”

Bai Shujie smiled slightly: "Is there anything strange?" This is the most realistic international relations, one moment the two countries were fighting to the death, but in the blink of an eye they have become good friends. ”

Zhao Jinxi shook his head: "I mean that if the British and the Japanese sign a friendship treaty, you will let Wang Xinlan issue a telegram to declare war on the British." Now that the Soviets and the Japanese devils have signed a treaty of friendship, are we going to declare war on the Soviet Union? ”

After all, what happens next, let's see how it will be broken down next time.
