"What, General Zhang, you want to form a submarine force? Do you have a submarine?" A few days later, in a secret room of the Northeast Frontier Defense Force's headquarters in Jilin...

Ives, who had just arrived here, stood up in extreme surprise after hearing Zhang Xinghan's explanation of his purpose.

"Yes, we can buy the submarine." Zhang Xinghan nodded calmly.

"Buy?" Ives was a little surprised. Would anyone be willing to sell a high-tech ship like a submarine to you?

Sensing the surprise and confusion in Ives' eyes, Zhang Xinghan smiled and said: "Mr. Ives, there are many seemingly impossible things in this world, but they still happen, and these are called miracles.

So I can tell you clearly that I have prepared enough submarines for us to use. Of course, only two submarines should be enough for training. Am I right?"

Ives nodded doubtfully: "Yes, General, if you are ready, my companions and I can help you train submarine sailors."

"Well, very good, Mr. Ives, thank you!" Zhang Xinghan stretched out his hand.

"You're welcome." Ives quickly stood up and shook hands with him.

Two days later, Zhang Xinghan and Ives took a plane and arrived at Dalian Lushun Military Port. A group of sailor cadets with good performance were gathered together, totaling 500 people, for training as the first batch of submarine cadets.

In the dead of night, Zhang Xinghan turned on his multifunctional watch on a secret coast. At this time, there were many options for naval submarine equipment in the watch's weapon list.

These include various types of submarines from Japan, the United Kingdom, the United States and other countries. Of course, most of these submarines were developed during World War I. Their performance is lagging behind and they are far from being able to meet future surface combat needs.

After all, these submarines are not the real submarines that were later developed specifically for underwater combat.

It is a ship used to sneak close to surface targets and launch attacks.

After careful consideration, Zhang Xinghan chose a German submarine with a more outstanding surname and a very good reputation and record in history.

The German submarines in the weapons list are now mainly divided into two types. One is the ordinary old V22 submarine. This submarine and the submarines of other countries use stealth to attack surface ships.

However, aspects such as speed and noise may be slightly more advanced than other countries.

The second type is the new submarine model xxi. This submarine was the most advanced submarine during World War II. It was the first submarine in the world designed entirely for underwater combat, instead of diving to attack and avoid surface ship attacks in the past.

The submarine is the prototype of modern submarines, and all submarines in later generations are developed based on it.

Its water displacement and submersible displacement are 1,621 tons and 2,100 tons respectively, with an upper draft of 5.3 meters, a total length of 76.7 meters, and a width of 8 meters.

The hull structure is a double-hull structure, and the power system is equipped with 2 manm6v40/46kbb 6-cylinder diesel engines, 4000 horsepower

2 sswgu365/30 electric motors, 5000 horsepower

2-seater sswgv232/28 static electric motor, 226 horsepower.

And equipped with twin-shaft sculls, its top speed on water is 15.6 knots (diesel engine)

Section 17.9 (electric motor).

What is more interesting is that because its appearance design is simpler and streamlined, its underwater navigation resistance is much smaller than that on the water surface, so its underwater diving limit speed is higher than its water speed.

17.2 knots respectively (electric motor)

Section 6.1 (static electric motor).

The endurance is also quite amazing, respectively 15,500 nautical miles/10 knots (water navigation) and 340 nautical miles/5 knots (submersible).

In terms of weapons equipment, it is equipped with 6 torpedo launch tubes (a total of 23 torpedoes) and 4 20mm anti-aircraft guns.

The crew is 57 people.

Compared with other old U-type submarines, the Xxi-class submarine has improved the old battery capacity of the original U-type submarine, which is about three times that of the viic type, greatly increasing its underwater range and shortening the time it takes to surface.

Level xxi can use the snorkel in less than 5 hours to charge, and you can have underwater

The ability to submerge continuously for 2 to 3 days at a speed of 5 knots without recharging. The Xxi class is also quieter than the viic type, making it less detectable during submersible. The Xxi class hull is also designed to be simple and streamlined.

Increased submersible speed and reduced submersible resistance make it harder to track and destroy.

The space and equipment inside the xxi-class ship are also larger and better than before. The large hull still has space after being equipped with multiple sets of batteries. At the same time, the ship has refrigeration equipment and shower rooms that are not found on other ships. In addition, the xxi-class ship has

There is also a special hydraulic torpedo system that can shorten the time of assembling the torpedo (it can be done in 2

(launches 18 torpedoes in 0 minutes), and the torpedo firing rate is also faster. The Xxi-class submarine also has a more advanced sonar system, which can aim and launch torpedoes without using a periscope to aim, increasing its concealment. The Xxi-class submarine

There are a total of 23 torpedoes, or 17 torpedoes and 12 mines.

These data were still absolutely ahead of other countries in the world at the end of World War II.

So now in 1934, it is undoubtedly the most powerful and terrifying underwater overlord.

Today, among all the naval vessels and naval technical equipment in the world, no warship or navy of any country can detect it while it is submerged and sink it.

It is even more powerful than the Zero fighter that was put into service ten years earlier by Zhang Xinghan, because in an air battle, the Zero fighter, no matter how superior it is to the Japanese navy and air force, may still be sunk by ground anti-aircraft fire or enemy air power.

In the ocean, as long as the Xxi submarine is determined to escape, no anti-submarine destroyer can catch up with it.

It is not difficult to imagine that if the Northeast Navy can have about two hundred to three hundred submarines in the future, it will be an extremely powerful underwater force.

Can attack any enemy naval fleet appearing in the Pacific.

As for attacking Japanese merchant ships, transport fleets, and even small naval fleets,

With its excellent battery life and submersible capabilities, it is no problem.

Fortunately, this advanced and epoch-making U-shaped submarine has been lifted and can be mass-produced.

Of course, the cost is also quite high, and the required kill value is almost equivalent to that of a five thousand ton light cruiser.

But it is indeed worth the money.

Zhang Xinghan gritted his teeth and produced twenty XXX submarines in one go. Coupled with the consumption of naval ships produced some time ago, the enemy kill points earned by Zhang Xinghan from this western expedition were basically exhausted.

The newly produced submarine is floating on the water and anchored, so there is no need to worry about whether it will move on its own or become silent.

These submarines are now waiting for skilled navy sailors to manipulate them.

After securing the submarine, Zhang Xinghan and Ives and others started preparing for training the next day with the first batch of naval cadets.

Of course, all training is conducted under extreme confidentiality.

In order to prevent the leakage of relevant information about the Xxi submarine, Ives and the others were monitored and accompanied by Secret Service agents throughout the training process.

The entire submarine training base is also tightly blocked by the Northeast Border Guard Force.

As for Ives and others, Zhang Xinghan had already approached Alice and signed a twenty-year contract with them. The contract stipulated that they were not allowed to leave the Northeast for twenty years, otherwise they would be charged with desertion.

Of course, Alice will arrange for Ives and his family to come to Northeast China to reunite with them.

Zhang Xinghan also instructed Zang Shiyi to arrange suitable accommodation for them so that they can live in China permanently.

Of course, just in case, Shen Xingye's Secrecy Bureau will track and monitor them 24 hours a day.

In fact, the chances of Ives and the others leaving without permission are slim. First of all, working in the Northeast Navy, they will receive quite high remuneration and high-quality material enjoyment, which is much better than they did in the UK.

You know, they are all retired soldiers in the UK and are forced to do work every day that they are not familiar with and the soldiers are not willing to do it.

Moreover, there is also the relationship between Alice, the future head of the Max family, and no one is willing to leave without permission at the risk of offending the Max family.

In comparison, in China, they can return to the jobs they love and are familiar with, be respected by others, and receive huge remuneration. Why wouldn't they do it?

After settling the initial training of the submarine force and other matters, Zhang Xinghan stayed in Dalian for two days and then took a plane back to Jilin City.

As soon as he returned to the headquarters, he saw Shen Xingye coming out to welcome him.

"Commander, you're back?!" Shen Xingye walked out and saluted, and Jiang Baili and others followed him out.

Zhang Xinghan waved his hand casually and asked: "Yizhi, what's wrong? Do you want to see me if you have something?"

As he walked towards the inside, Shen Xingye followed, nodded and said: "General, I have good news to report to you. The Secret Bureau has completed the construction of branches in Shanghai, Nanjing, Hangzhou and Wuhan.

According to the latest news from our branch agents, we have learned something about the current situation in Japan."

"Oh? How is Japan doing now? Are the Japanese doing anything unusual?" Zhang Xinghan asked curiously.

Everyone had arrived at the headquarters hall. Jiang Baili personally poured a glass of water for Zhang Xinghan and sat down in order.

As soon as Shen Xingye sat down, he replied: "According to preliminary information, the Japanese are stepping up their efforts to train new troops and expand their military industry. It seems that they are always preparing to avenge their previous humiliation.

One piece of news deserves our attention, that is, the Japanese army has seized a batch of our weapons during the battle with our army, such as our army's general-purpose machine guns and individual semi-automatic rifles. They have recently had considerable contact with Western countries.
