In particular, the rich oil-flowing countries in the Middle East are vying to wave these large amounts of gold and rice dollars to buy them. Pen Fun Pavilion www.biquge.info now the two saplings have become the best selling items in the world, far surpassing the oil that used to be the number one.

The third watch was woken up in the middle of the night, Li Gang felt a little unhappy, but when he saw that it was Sun Hao, the unhappy look on his face immediately disappeared without a trace.

"Mr. Sun, are you still letting people sleep?" Li Gang said in a joking tone.

"Mr. Li, I'm really sorry to disturb you in the middle of the night, but I have something urgent, so I'm very sorry."

"Tell me, what can I do for you?"

"I need to build three steam engine submarines, which are guaranteed to be able to dive for about an hour, with a displacement of about 600 tons, and a speed of 10 knots above the water and about 6 knots underwater. Steam turbines are used for surface navigation and electric motors for submersible navigation, and four 450 mm fish launch tubes are installed. Torpedo technology is also very backward, with a range of about 800 meters and a speed of about 25 knots. "Originally, Sun Hao's own shipyard could also be built, but the speed was not as fast as Li Gang's here, so it was worth bothering Li Gang.

After Li Gang heard this, he felt a little strange in his heart, he had already handed over 120 advanced submarines to Sun Hao, why did he want this old-fashioned submarine?

"Mr. Sun, according to the technical requirements you said, this submarine is very similar to the U-boat of Germany during World War I, not only is its attack power not strong, but its performance is also very backward. But the U-boat is powered by a diesel engine and a battery, so I don't know what you're doing with such a submarine? ”

"Mr. Li, I use such a submarine to fool customers." Sun Hao had an idea and said casually.

Li Gang heard that Sun Hao was using it to fool customers, so he said: "Mr. Sun, since it is to fool customers, it is a good model." ”

Sun Hao heard that the submarine he casually said was the U9 submarine of Germany during World War I, and his heart began to be happy. The U9 submarine does not seem to be weak in attack power, but it shines in World War I. However, such a submarine is only equipped with a 450mm torpedo, and it can deceive not only the British, but also the world.

However, Sun Hao thought that there are so many countries in the world, and many countries will know that Huaxia has a powerful battleship in the future, and they will definitely come to buy it, so can't he sell the battleship?

As long as the power of these warships sold is replaced with the power of the early stage of World War I, these warships are not equipped with radar and fire control and aiming systems. Even if they buy more warships in the past, the threat to the Huaxia Navy is not very great, but it is a live target for the Huaxia Navy.

Thinking of this, Sun Hao seemed to see countless gold coins smacking beside him, and saw many countries holding gold coins in their hands, and then ran to beg to buy warships.

"Mr. Li, then build according to the U-boats of Germany during World War I, a total of 50 submarines will be built." Sun Hao built 50 U-9 submarines in order to sell this submarine to the Germans, so that they could own the submarine in advance.

If you leak some news in the future, can you let the Germans carry the black pot this time? Let these countries turn their suspicions to the Germans. In this way, not only can you earn a lot of money, but you can also get out of this matter.

Li Gang didn't ask Sun Hao why he was building 50 U-9 submarines, anyway, as long as he had money to earn.

"Mr. Sun, when you get out of the submarine, do you want other warships?"

"Yes, I'll build me a hundred Elizabeth-class battleships and 100 prestige-class battlecruisers, but the Elizabeth battleships must be as good as they were in history. The prestige-level battle patrol canceled all the air defense, radar, fire control, depth charges, and aircraft ejections, and replaced the power with the power of the First World War era, and it can't be seen that it can be built in half a year? ”

"No problem, but I don't need antiques this time, I just need wood and saplings from iron pear trees and nanmu."

"Yes, every question. However, I had to build three U-9 submarines in 20 days. ”

"No problem!" Li Gang promised that with the scientific and technological ability of future generations, it can be said that the construction of these old antiques can be said to be a matter of hand.

"Mr. Sun, Germany developed a kind of warship that can dive during World War II, do you need a few?" Li Gang wanted to expand the order, so he sold Sun Hao the diving warship developed by Germany during World War II.

Diving battleships? Sun Hao was a little puzzled after hearing this, Germany's industry is very developed, especially the technology of precision manufacturing. During World War II, it can be said that the Seiko manufacturing industry was almost at the forefront of Germany, but I haven't heard of Germany developing a warship that can dive?

"Mr. Li, can you take a look at the information of this diving battleship?" Sun Hao looked very yearning, and Sun Hao was very curious about the battleship that could dive. During World War II, it was not impossible for Kou to develop 400 submarines capable of carrying aircraft, and for Germany to develop submarines.

Li Gang smiled and put the information of the diving battleship in the trading machine, and soon, the virtual display showed the information of the diving battleship.

Sun Hao saw that in history, not only Germany developed underwater warships, but also Britain, France, Rakshasa and the United States have developed and have built a few. However, due to the stacking technology and lack of practicability, this kind of battleship called heavy artillery submarine did not play any role in actual combat. In addition, when facing the aircraft carrier battle group, it was completely powerless to fight back, and was later abandoned by various countries.

Sun Hao thought of the development of various radar and anti-submarine technologies during World War II, and it was difficult for this kind of warship, called heavy artillery submarines, to exert its combat effectiveness. However, before the advent of radar and anti-submarine technology in World War I, it must have been very popular to get such heavy artillery submarines out and sell them to those belligerent countries.

Thinking of this, Sun Hao showed a hint of a smile. If Germany were to buy dozens or hundreds of its own heavy artillery submarines to block the lifeline of Britain and France, this would be more practical than submarines.

However, he had to replace the engine and naval gun technology with the technology of the First World War, so as not to allow the Germans to acquire advanced technology.

Hahaha! Thinking of this, Sun Hao couldn't help laughing. It seems that they have seen that the British and French transport ships are facing the continuous ravages of German submarines and heavy artillery submarines, and there is no other way to beg him to sell them heavy artillery submarines, and then the British and French and Germany launched a sea heavy artillery submarine war.

Sun Hao saw the historical French cruiser Sukuf, which installed 203 mm heavy guns on the submarine, which was the same level as the heavy cruiser! And it is equipped with a seaplane, which is the first submarine in the world that can carry aircraft. Because of the stacking technology and lack of practicality, this submarine did not play any role in real combat.
