Pixiu, it's really Pixiu. A 2,000-ton submarine cost Li Guang nearly one million US dollars. And that's not even counting the looting of alloy steel plates and hundreds of tons of lead-acid batteries.

If you want to really calculate the cost, the submarine cost more than 1.8 million US dollars. It's literally worthy of the name - Pixiu. It's too good to swallow money.

On November 1 of the 38th year, the pickup truck returned from selling non-ferrous metals in Germany, just in time for the launch of the Pixiu.

For seven months, hundreds of people worked around the clock, accompanied by a huge amount of money. Now it's up to us to see the results of the sea trials.

Not only Li Guang was excited, but almost all the coastal resistance fighters were excited. Escorted by the PlayJP and Pickup, the Pixiu quietly left the port at night without attracting the attention of the Uruguayans. Anyway, now the shipyard has several ships launched every month, and it is not surprising that another one is launched.

Under Li Guang's deliberate secrecy, there are really not many people who know about this submarine except the workers, and these workers are either Chinese or skilled workers recruited from the United States, and there are no Uruguayan locals at all.

Coupled with the fact that the dock is closed, it is difficult for outsiders to find out. Of course, absolute secrecy is impossible, but Li Guangjin is not an ordinary figure, and he is also a high-class person in Uruguay, and his influence has increased rapidly, so he can naturally avoid a lot of trouble.

The appearance of the submarine is swarthy and a little odd. This was Li Guang's idea, and even the designer didn't figure out what kind of paint was painted. For these lacquers, Li Guangke spent a lot of energy. Several members of the sonar team of Ji Kelian experimented countless times before he came up with the formula. This patent leather is effective against sonar detection, and the returned waveform and sound are closest to the submarine reef. The experiment was very laborious, but the material was not expensive at all, that is, the rubber sheet was beaten into epoxy resin at the end of the year, and brushed several times.

Li Guang couldn't buy radar for a while, and there was no way to test the stealth surname. And in this era, radar has not yet become popular in the navies of various countries, and now no one has thought about the concept of stealth at all.

Even the United States and Britain, which have the most advanced radar technology, have just set up ground-based radar stations, and the radars on warships are only equipped with one or two sets of equipment that the Americans have just experimented with.

As for the book, the development of the radar has just begun. There was no shortage of first-class technical experts and electronic engineers in China at that time, and these people successfully developed a fairly reliable cavity magnetoelectric tube in 1939 (10cm wavelength, which was only successfully developed in Britain in 40 years, but it was immediately applied to radar and actual combat), which is also the terrible thing about this book. However, it was not a matter of time and a half that I wanted to make radar practical. Don't worry about Pixiu for the time being.

For Li Guang, this is also one of the shortcomings of the Pixiu, the ranging only relies on the scale on the periscope. The accuracy of sonar is extremely low, and it is not accurate ranging at all. It is only possible to roughly determine whether there is an obstacle ahead, that is, to avoid the submarine from hitting an iceberg or an island.

The sea trials were carried out for a whole month, of which nine were returned to the factory for repairs. In the end, Li Guang was very satisfied, and everyone was very satisfied.

The most outstanding indicators of submarines are comparable to those of warships. The maximum speed above the sea surface is 24 knots, and the maximum speed under the sea surface is 16.5 knots. The silent speed can also reach six knots.

And one of the hardest indicators of the Pixiu submarine, the diving depth, has fully reached the design depth - 200 meters.

At this depth, there is nothing wrong with it, except for the creaking sound caused by some stress in the hull. However, when testing this project, several small failures appeared, which made Zheng Xuechang drenched in a cold sweat in the cabin. Later, Li Guang also personally tested a deep dive in the submarine, and the sound of stress deformation was indeed terrifying.

On 1 December, the Maritime Resistance Army could not wait to be dispatched. Li Guang served as the supreme commander. Zheng Xuechang is the captain of the pickup, and Huang Zhonghua is the captain of the PlayJP. Su Qing is the captain of the Marine Corps.

The captain of the Pixiu was concurrently served by Li Guang.

There is a shortage of talent in the Naval Resistance Army, and no one has experience in submarines. On the contrary, Li Guang is most familiar with submarines. At Li Guang's insistence, everyone had to agree to Li Guang to take the risk.

Li Guang became the first captain of the Pixiu.

There is another feature of this trip. The PlayJP is equipped with the only existing fighter of the Naval Resistance Force. It is said to be a maritime reconnaissance aircraft.

There is a simple one-arm crane on the deck, which can put a small plane weighing more than a ton on the sea at any time. Wait for the plane to complete its mission, and then hoist it onto the ship.

After the last battle, the pickup has not robbed for more than half a year, and the robbery is obviously addictive, and the soldiers have long been holding back their howls.

Now the full crew of the pickup is 80 people, each of whom has experienced tens of thousands of nautical miles of sailing, and all of them can be regarded as full-fledged naval soldiers.

The soldiers at all posts are extremely proficient. If the Pickup is a real destroyer, then it is completely capable of fighting. However, for the Maritime Resistance Army, it is not easy to have a destroyer, and a Pixiu has already spent money like flowing water, draining Li Guang's funds. Now as a fanatic of cannon and giant ship doctrine, Zheng Xuechang is now actually expecting the Baxia to be launched. Although the displacement of the Baxia is not large, it can be regarded as a real warship after all. And not like the Pickup, which is a practice ship to put it bluntly.

After all, the Pixiu is a submarine developed for the first time, and it has such and such problems, but there is no doubt that the surname Neng is really good. (In fact, if you only look at hard indicators, it has surpassed the most advanced submarines in the world at this time.) ）

The disparity in weapons between countries in the early and late stages of World War II was enormous, and war was the most stimulating to human creativity. In almost every type of weapon, the level of technology before and after the war has more than doubled, and various new technologies have emerged one after another.

Thanks to Li Guang's thinking, this Pixiu, except for some supporting software, is actually close to the highest level of World War II in history.

The submarines of this era are really surface ships. No submarine can stay on the surface for long periods of time. And the Pixiu is a real submarine in this sense. Thanks to the presence of a snorkel, the Pixiu can sail continuously at periscope depth, charging as it travels. And not like other submarines, you have to float and recharge after a while of diving.

Li Guang was almost in a state of excitement during the more than half a month of sailing. The members of the various departments on the Pixiu are all the elite of the Naval Resistance Force.

All of these men had gone through the simulation training on the pickup, and the brothers were extremely quick to get started.

The entire Pixiu submarine is divided into two layers, the outer layer is the water tank, and the inner layer is the pressure-resistant shell. The interior is divided into two parts, the upper and lower parts, and the lower part is mainly nearly 600 tons of batteries. And it is divided into four compartments. The head part is the torpedo compartment, then the command compartment, the third section is the living compartment, and the last section is the engine room. There are hatches with a diameter of 80 centimeters between the compartments, which can be closed in the event of an accident on the submarine to ensure the safety of the crew.

The Pixiu was originally based on the S-class submarines of the United States, which were originally only 1,000-ton submarines. In order to ensure that the endurance can reach 16,000 nautical miles, it is necessary to increase the reserve space of fuel and living facilities, and the hull will be expanded.

Due to Li Guang's preference for the endless pursuit of speed, the Pixiu chose a twin-pack 2,500 horsepower diesel engine. In order to make the power of underwater navigation more passable, the endurance reached three days, and the size of the battery pack was also increased, and the battery pack alone occupied a displacement of 600 tons, which is extremely amazing.

After a series of improvements, the Pixiu was upgraded to its current class - 2000 tons.

Originally, according to the design, there should be 64 people on board the Pixiu submarine, but for the sake of training and to cope with the unskilled manpower, 96 people were arranged on the submarine this time.

As for the crew on the Pixiu, Li Guangke really bothered, and in order to match the troops of various departments, he almost screened the more than 600 people of the Maritime Resistance Army. Don't look at just a 2,000-ton submarine, there are seven or eight majors. From the division of duties (equivalent to the type of work) of the personnel in the submarine, you can see how complicated it is. Yes:

Captain and deputy captain, chief and deputy clerk, military doctor, translator, chief and deputy navigator, helmsman, elevator helmsman, torpedo chief, torpedo crew, chief and deputy mechanical and electrical chief, navigation signal soldier, radio soldier, sonar soldier, engineer engineer, electrician, cabin soldier, cooking soldier, gunner. There are eighteen types of work, and the organization is much more complex than that of a merchant ship.

Among them, there are seven members of the torpedo squad in the torpedo compartment, all of whom are the most skilled electric mine operators. In particular, Quan Yonghai, the squad leader, is extremely proficient in calculating and adjusting the angle of the submarine, and is a veritable master.

The three people that Huang Zhonghua poached from Mawei Haixiao have all come in handy now. This Quan Yonghai served as the deputy gunnery chief when he was on the pickup, and he was already the squad leader of the torpedo squad on the Pixiu.

In the command module, the first mate Ren Tianyang is also from the Mawei Naval Academy, and has considerable research on navigation and operations.

And the helmsman and elevator are all strictly trained, and it turns out that they can also read and work on the pickup.

The sonar was played by Ji Keliang, the first Shunfeng ear of the Naval Resistance Army, and another music student.

The members of the marine engineering class, a total of 20 people went to sea this time, are more familiar with the engine and reducer and other mechanisms, in fact, this part is installed by them. The purpose of almost every screw is clear, and the direction of each wire of the battery pack and power distribution cabinet can be found without drawings.

The Deputy Observers are also the most discerning members. In the process of selecting the boaters, Li Guang found that the role of observer does not rely entirely on eyesight, but on his innate ability to catch unusually sensitive in the field of vision. This was a small discovery, and it later became a complete method for selecting observers. (Observers on submarines are generally the captain and first mate.) This time a dedicated observer was added)
