After introducing the performance of the miniature submarine to Fang Duo in detail, Lin Dong saw that the other party's eyes had begun to flash with a terrifying light.

This so-called Swordtail Fish miniature submarine is still very different from the one in Lin Dong's hands.

First of all, in terms of power, this is just a conventionally powered submarine, which is simply incomparable to Lin Dong's miniature nuclear reactor technology.

However, the Swordtail is a typical primary marine warfare equipment with high attack and low defense. This is more suitable for Huaxia than the miniature submarine in its own hands.

It is precisely because it does not have too heavy defensive armor that its speed can be maximized, far exceeding that of normal submarines by four or five times, and it can quickly complete the reconnaissance mission of the entire sea area.

Compared with other surface ships, submarines have relatively strong concealment capabilities. Because it operates underwater and uses seawater as a cover, it is difficult for reconnaissance planes and reconnaissance satellites to discover its whereabouts.

However, the sound of the submarine's engines and propellers as it sails, and the reflection of sound waves from its massive body, make submarines easy targets for sonar capture.

Not only that, the periscope of the submarine observes the surface of the water when necessary, and the snorkel of the conventionally powered submarine sticks out of the water surface from time to time to suck in air, although it is not obvious on the rough sea, but it will also give the enemy's search radar an opportunity.

What's more, conventionally powered submarines also need to surface regularly to be propelled by diesel engines and charge the battery, which accounts for about 20% of the patrol time, so there is no concealment at all.

In order to improve the survivability of submarines, the major naval powers attach great importance to the development of submarine stealth technology. Although some achievements have been made over the years, it is still not as good as the swordtail fish in Lin Dong's hands.

"Since Captain Fang is from the special forces, he still knows something about submarines."

Lin Dong said in a good time.

"At present, the submarine reconnaissance equipment is mainly sonar, and as long as the noise emitted by the submarine itself is controlled, it will achieve a significant stealth effect.

However, in order to achieve real results, it is not possible to achieve success in a short period of time in terms of technology and materials.

In my Swordtail, the engine and transmission used in it are very quiet, and with the sound insulation and sound-absorbing equipment on the periphery, the noise can be successfully eliminated.

As for the propulsion device, it is a magnetofluid propulsion, which fundamentally solves the problem of ordinary propeller noise, so that driving below the surface of the water, almost no sonar detection can detect its existence. ”

Looking at Fang Duo's shocked appearance, Lin Dong introduced again: "Although it is conventional power, the power system in the submarine is different from all existing submarines, the continuous cruising time is more than four months, and the power plant does not rely on air, so there is no need to go out for ventilation from time to time, so the possibility of being detected is almost eliminated."

Moreover, the special microwave scanning system that comes with the submarine can form a sphere scanning area at ten kilometers around the submarine, so any stealth method of the other side will fail.

Everything is hidden in this scanning area, even a fish can be clearly realized on the radar cross-section, so it can complete any attack or reconnaissance mission underwater, without the use of periscopes. ”

"What about the attack power, how is its attack power?" Fang Duo asked with some eagerness.

"Since it is said that it has a high attack and low defense, its attack power is naturally not weak." Lin Dong explained again.

"Although it is only armed with two torpedo launchers, it is absolutely powerful. It only takes two torpedoes to hit at the same time, and then you can directly sink an Arleigh Burke-class destroyer! ”

Fang Duo's eyes widened instantly.

"You're not kidding, are you?"

You must know that the Arleigh Burke-class destroyer of the US Navy is known as the best destroyer in the world, with a full load displacement of 8,315 tons, and even many anti-ship missiles dare not say that they will sink it with one shot.

Unless it is like a modern-class destroyer, equipped with SS-N-22 missiles (NATO code name "Sunburn"), a conventional warhead of 300kg. It is still possible to sink a 7,000-ton destroyer.

However, Russia's "Sunburn" and "Granite" are known as the world's largest anti-ship missiles, and their power is not at all comparable to that of torpedoes.

And the overall size of this swordtail miniature submarine is less than twenty meters, so how big can it carry torpedoes?

Compared with those eight or nine meter-long anti-ship missiles, it was almost like a toothpick, saying that such a weapon could sink the Arleigh Burke-class destroyer, Fang Duo felt that Lin Dong was not talking in his sleep!

"Do I need to tease you here?" Lin Dong glanced at Fang Duo and said.

Call!

With a long exhale, Fang Duo stabilized his mood and said, "So, Lin Dong, I don't know if the design drawings of this kind of submarine can be sold to us?" ”

Lin Dong's eyes moved slightly, his fingers tapped on the table, and he said softly: "Then I don't know what price you plan to use to buy the blueprint of my swordtail fish?" ”

"This ......" Fang Duo paused slightly, and said: "I don't know much about this, but you can tell me your asking price, I will quote this price, and everything needs to be appraised by a professional." ”

Lin Dong nodded slightly, this is also a necessary procedure.

After all, you can't say anything yourself, and people will believe it, right? And for a layman like Fang Duo, even if Lin Dong handed him the design drawings, he couldn't see why.

"Well, I'll give you a copy of this analysis diagram, you can take it, and as for whether to make this transaction next, then ask a professional to judge.

It's just that my asking price is not cheap, and there are a lot of technologies involved that are far beyond the current ones, and these are really precious things, so less than 100 million US dollars, so you don't have to open your mouth! ”

Fang Duo and Lin Xia, who were present, gasped at the same time, looking at Lin Dong with a calm face, with incredulity on their faces.

"You guy!" With anger on his face, Lin Xia gritted his teeth and said, "You really dare to speak!" Aren't you afraid that so much money will stone you to death? ”

Lin Dong shrugged his shoulders indifferently, smiled slightly, and said, "Do you do business, is there still someone who dislikes the little money you make?"

And sometimes, some things can't just look at the surface, these technological things, for the country, can not be measured by some money.

I am also making my own contribution to the development of the motherland! ”

"You're ......!" Lin Xia felt that he was about to be blown up by this guy's shameless remarks. Looking at Lin Dong's smiling face, he couldn't wait to punch him directly.

Fang Duo groaned and nodded in agreement with Lin Dong's proposal.

Although he was also shocked by Lin Dong's words just now, unlike Lin Xia, he was not angry in his heart, but agreed very much with Lin Dong's last sentence.

A lot of times, technology isn't something that money can measure!
