After this exchange of shotguns for cannons, the Wyvern 201 cruiser suddenly took on a new look. Especially after the main gun was replaced, there was no opponent in the light cruiser of the little devil.

At present, it has been able to form a small fleet with the Flying Dragon 301 destroyer (Hibiscus Maru) and the Flying Dragon 302 destroyer (Chaoyan Maru) to undertake coastal combat missions, relieving the defensive pressure on the west coast of Pyongyang.

These three warships hid at the Jiaodao pier and did not go out on patrol during normal times. The Flying Tiger Squadron at Pyongyang's Gangnam airfield is to provide them with air cover.

Together with the air defense regiment of the 1st Division of Shi Liancheng on the shore, they constituted two levels of air defense, and at the same time, they were also a killer weapon, which could directly threaten Andong and Lushun Dalian.

Your own capital is too small, as long as you have a certain deterrent. There is no need to go out and hang out until there is no submarine escort. This is Bai Shujie's basic guiding ideology, which is the so-called "asymmetric strategy".

It was not until mid-March 1938 that the Feilong 201 cruiser, the Feilong 301, and the 302 destroyers were all refitted, and Bai Shujie finally breathed a sigh of relief.

At present, the combat effectiveness of the army, navy, and air force of the Flying Dragon Expeditionary Force has long been formed, and it has also been tested in bloody battles for more than ten years.

The Air Force and Navy have a rudimentary shape, like a baby. But with a certain foundation, there is a platform for practical yàn to continuously accumulate experience.

For example, Bai Shujie's core shipyard, a batch of equipment carefully selected from Dalian Shipyard and Jinzhou Shipyard, and more than 2,400 workers and technicians after strict inspection, who personally modified three warships and surveyed the dimensions of all components. There are more than 30,000 drawings alone.

Now these drawings are being enlarged at the Cangyunli Military Shipyard, and at the same time they are doing another thing, which is to dismantle a 10,000-ton cargo ship, which is the thing of the little devil who seized it in Port Arthur. It was a supply ship, the construction of which began in 1917 and had a full load displacement of 31,000 tons.

Bai Shujie's meaning is very clear, we have captured a total of two 10,000-ton freighters, and if we can't dismantle one, we will also dismantle the other!

The English word in China is called "China demolished", how can you progress without demolition?

After dismantling, it was reassembled, and then disassembled. The final goal was to use the steam turbines of two 10,000-ton freighters to "piece together" an enlarged version of the Wyvern 201 light cruiser.

It is required that the standard displacement should reach 15,000 tons, the full load displacement should be 18,200 tons, the speed should be 30 knots, the endurance should be 6,500 nautical miles, and the weight of armor laying should not be less than 3,600 tons.

Not to mention, the technicians of this era can really work hard, it can be said that they never sleep, which is really commendable.

They have all worked under the forced management of the little devils for seven or eight years and have endured all kinds of humiliation. Now I have the opportunity to work hard for the country, so I have a lot of enthusiasm for work.

Of course, Bai Shujie did not expect it to be achieved overnight, nor did he expect this assembled cruiser to really go to the battlefield.

The point is that he needs a weapons test platform, which is also a real training ship, which can be converted into a mobile supply ship or a hospital in the future.

The tonnage of one light cruiser and two destroyers is too small for high-powered weapons to bear. Without carriers and weapon platforms, many ideas cannot be turned into reality.

Of course, in these processes, Bai Shujie turned into a "shipbuilding expert", and he was able to draw four sets of standard drawings from his hands, which surprised the chief engineer and deputy chief engineer of Cangyunli Shipyard!

For Bai Shujie, it is not to mentor these real experts, but to broaden their horizons. These four sets of drawings are actually quite simple:

British heavy cruisers of the "Exeter" class (full load displacement 10550 tons): length 175 meters, width 17.4 meters, draft 5 meters;

Soviet cruiser "Chabaev" class (full load displacement 14100 tons): length 199 meters, width 18.7 meters, draft 6.9 meters;

German battlecruiser "Scharnhorst" (full load displacement 38100 tons): length 235 meters, width 30 meters, draft 9.93 meters (37303 tons);

The German battleship "Bismarck" (full load displacement 41,700 tons): 248 meters long, 36 meters wide, 15 meters deep, designed with a full load draft of 10.2 meters, a speed of 34 knots, and a fuel load of 7,400 tons.

Bai Shujie handed over the drawings to the technicians, and the basic requirement was to hope that they would learn more from the innovative spirit of others and not always keep their eyes on their toes.

"Masters: My consistent principle is that failure is forgivable, and those who do not want to make progress cannot be forgiven." Bai Shujie said earnestly: "Why is my country backward, why is it bullied by such a small reptile as a little devil?" It is caused by the greed for pleasure and the lack of progress. ”

"I don't want you to be a blockbuster, and I allow you to fail countless times. However, every time you fail, you must figure out why you failed, and you must not fail twice on the same issue. If it doesn't work in one year, we will use it for two years, and if it doesn't work in two years, we will use it for ten years. As long as we are improving every day, we will succeed. ”

"I want you to open your mind and not think that you are amazing. The small-scale peasant consciousness that guarding against people is better than guarding against Sichuan will never be able to achieve anything. Learning from each other, learning from each other's strengths, and improving together is the real way of development. ”

"I'm not a stingy person, as long as you are willing to study hard and are willing to keep improving your shipbuilding skills, I can pay all the price. If you think it's necessary, even if the Wyvern 201 is dismantled tomorrow, I don't have any opinion. ”

A study program in shipbuilding was arranged, and Bai Shujie finally left the naval base. Because there are so many issues that he needs to calm down and think about it, it is impossible to focus on one thing.

For example, the second-generation armor-piercing incendiary bomb that was suddenly taken out and used this time, although others looked very powerful, Bai Shujie knew that it was not in place at all. Especially after hearing about the bombing, he thought that there was too much difference between him and his inner thoughts.

After coming to Pyongyang, Bai Shujie received a large amount of magnesium powder because of the acceptance of magnesite mines. Therefore, in addition to Huang Lin, magnesium powder was added to the second-generation napalm to increase the instant temperature of explosion and combustion.

Bai Shujie's territory is too small, his industrial capacity is too weak, and he has no way to produce really high-precision weapon systems for the time being, so he can only look for weapons and ammunition that are "simple to manufacture" and "raw materials can be seen everywhere", which are "inexpensive" and "have great lethality".

Over the years, Bai Shujie has been pondering, but there is a shortage of manpower. This time, he came to Pyongyang and brought more than 10,000 young people from Jinzhou, Yingkou, and Dalian, including more than 1,000 middle school students.

The Feilong Institute of Physical Chemistry was finally established on the basis of Bai Shujie concurrently serving as the director. The institute currently has three main research projects:

One of the topics: the research of new gunpowder, improve the performance of propellants, and increase the explosive power of shells, bullets, grenades, mines, and grenades.

Topic 2: Carry out a large number of practical products to find flammable substances that can produce high temperatures, such as magnesium powder and aluminum powder. There is no need to study magnesium powder and aluminum powder, because Bai Shujie understands it very well. The key is that potassium and sodium need to be focused on research.

Topic 3: Liquefied gas research. Pyongyang is a place where there is a lot of coal, and if the equipment of the gas plant is used to cool and pressurize the gas into liquid, this is the current focus of research.

The kind of bomb that Bai Shujie painstakingly wants to develop before other countries is a high-energy "cloud burst bomb"!

He believed that with the current chemical conditions and levels, it was impossible to produce large quantities of gunpowder for aerial bombs. In order to solve this problem, since six years ago, Bai Shujie has been envisioning a "cloud burst bomb".

The main charge of a cloudburst bomb is a cloudburst agent, also known as fuel-air explosive. Cloudburst is a high-energy fuel, not an explosive. Therefore, it is also called air bombs, fuel air explosives, oil and gas bombs, etc.

Explosives rely on their own oxygen during a detonation reaction, while cloudburst bombs make full use of the oxygen in the atmosphere in the explosion zone when they explode. Under certain detonation conditions, the cloud explosive agent is thrown away, mixed with the air and violently explodes, which is called cloud detonation.

Since the cloud detonation consumes the surrounding oxygen, an oxygen-deficient area can form within the area of effect, suffocating organisms to death. Cloudburst agents release much higher energy than explosives of equal mass, and the blast wave generated can damage large areas of military objectives.

During the Gulf War, a group of British scouts patrolled the border between Iraq and Kuwait when the U.S. military dropped a heavy cloudburst bomb to attack a ground target. The British soldiers immediately reported to the command that they had discovered that a certain war zone had been attacked by a nuclear bomb.

Since then, the cloudburst bomb, also known as a "sub-nuclear weapon", is second only to nuclear weapons in human history, but it has no nuclear contamination.

Bai Shujie started from the study of napalm, and his ultimate goal was to create a "cloud burst bomb". Because the little devils like to work hard and waste money the most, and build strong fortresses and tunnels everywhere.

For example, the northeast side of Pyongyang after turning over the mountain beam is the Ronan Fortress of the little devils, and the Shengshan Fortress in Sunwu County, Heilongjiang Province. Without heavy artillery with a caliber of more than 460mm, don't even think about it.

Bai Shujie thought that a direct attack on Ronan Fortress would at least be prepared to sacrifice hundreds of people. This was an unprofitable business that could not be done for the time being, so he ordered Chen Jie's second division to establish a defensive position in the Wolf Forest Mountain Range.

Just because you can't do it for the time being doesn't mean you can't do it forever. Only by taking the Ronan Fortress, controlling the Namgang Port and Wonsan Port, and then taking the Najin Fortress in the northeast corner, can we talk about controlling North Korea.

Due to the unique lethality and explosive effectiveness of the cloud burst fuel air bomb, it can be applied to a variety of combat operations, and naturally it has become a key research target of Bai Shujie.

Such as killing and injuring combat personnel at support points, artillery positions, assembly areas, etc.; destroying fortifications, command posts; Eliminate garrisons on islands and reefs; destruction of large targets such as airports, docks, stations, oil depots, ammunition depots, etc.; Attack ships, radar stations.

This time the sudden attack on the aircraft carrier Akagi, the armor-piercing incendiary bombs ordered by Bai Shujie to be used, are gradually approaching the category of cloud burst bombs. In the napalm bomb, yellow phosphorus, magnesium powder, aluminum powder, potassium and sodium elements are added, so the power is several times greater than the original.

However, Bai Shujie still wants to go further, hoping to destroy a destroyer with 10 500-kilogram third-generation napalm; With 50 third-generation napalm of 500 kg, destroy an aircraft carrier.

Now the research has entered a critical period, and the third generation of high-power aerial bombs is divided into two varieties: armor-piercing napalm bombs and high-pressure gas incendiary bombs!

No matter how powerful they are, you have to knock these bombs down on the enemy's head to be effective. Therefore, after Bai Shujie was busy with the construction of the air force and navy, he is now thinking about the projection carrier.

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