The site of the sinking of the John Barry is 8,500 feet, or about 2,590 meters, a depth of 259 atmospheres at the most rough calculation.

The pressure is so high that it is explosive, and the difficulty of salvage operations in such an environment can be imagined.

Jamie Bostwick also told Zhang: "The first half of the Barry is sinking, about 10 degrees to the left.

That's all good news, as the third cargo hold where the silver ingots are stored is on the starboard side, so at least there is no need to worry about the hull tipping over when pulling things out of the wreck.

But that section of the cargo hold was actually reinforced, and the information we got from the shipyard in advance was not marked at all, and the underwater cutter equipped with the Mir basically did not move."

To put it bluntly, the large-scale production of free wheels in the United States during World War II was for a "fast", not fast speed, but to build fast, and the performance indicators and quality of cargo ships were so-so.

The result of so-so is that the manufacture is simple and fast, and the number of free wheels is huge, which naturally leads to the fact that the quality of some free wheels is really so-so.

Wartime standards, speeds, you don't think you can be elaborate, there have even been cases of the ship being open at the sea, and the ship is broken in two.

The structural strength is defective, and the metal fatigue and overload after high-strength use

Not particularly sturdy anyway.

In order to avoid this situation again, some of the free-wheels manufactured in the middle and late stages were structurally reinforced during construction, and some ships that were used at sea for one or two years after micro-cracks and fatigue of the metal structure were also partially reinforced.

This would have been the case with the veteran sailor of the Deep Diver who had fought in World War II, not on the John Barry since the new ship.

At that time, the crew obeyed the needs of the war and often changed ships, especially the experienced old crew members who were responsible for bringing new people.

Anyway, the free-wheels are all printed in one mold, and they can work the same and have fun on any ship.

The John Barry was built at a small private shipyard on the south side of the West Coast, which had been out of business for decades and now had no drawings for the ship, which Jack was referring to as standard drawings for free-wheels.

In fact, even if the shipyard were still there, there would not be any drawings that belonged to the "John Barry" alone: mass-produced things could be launched in a few weeks, and they were all the same set of drawings that won the world.

Sailors often change, and even if they don't, it is unlikely that they will know that the hull of the third cargo hold has been reinforced;

Even if you can see it, who will pay attention to this in those years?

Even if you have paid attention to it, it has been half a century, and you have long forgotten about it.

"You can only use blasting, I have contacted the company, one or two hundred meters depth blasting technology, personnel and equipment can be found in the international civil market, deeper are hidden, don't even think about it, let alone blasting operations at a depth below a kilometer, even if there is a state secret.

We calculated that if the cutting method were forcibly used, and the two Mirs would take turns to rotate on and off the axis, it would take more than a month, or even a quarter.

The world can afford to spend it, but the cost is too great, and the worst thing is that if you do that, the two deep submersibles will wear out too much. ”

The Jack paused for a moment, and then said, "So this boss, see if you have a way?"

Underwater blasting is a trivial matter, even those who pirate ancient shipwrecks in the South China Sea know this skill, but the water depth in those sea areas is less than one meter, and the depth is a few meters, more than ten meters, and there is no comparison at all.

The blasting within a few tens of meters of its own salvage company has done it in the Java Sea, 2590 meters?

Catch the blind!

The company is blind, and Zhang Nan is also blind!

"Jack, there is no way for the company's professionals, am I a liberal arts student, do you understand?

I've got a hairy solution!"

It's all rude, but the old saying doesn't mean "it's difficult to find a leader", although it doesn't work, but you still have to find it.

This Jack Bostwick is also in a hurry to go to the doctor, not only the company's leaders are useless, but even the technology is not in a position for the time being, and he is still asking around.

He also had to find a boss with difficulty, maybe the boss with great powers would have a way.

As soon as Zhang Nan's foul mouth exploded, he felt that it was not a matter of pretending to be a dead dog and playing helplessly, and said: "Our deep submersible can bring down the finished bomb, but there is no suitable bomb, right?"

"Yes, boss. The water pressure is too high, and the bombs of the general structure are either flattened or seeped into the water, and the problem of detonation is even more difficult."

The general "light-body explosives" can be used when blasting in shallow water, and there is no hope at all in the state of deep water pressure, and the detonation cannot be done, so the finished product has to be exploded-bombed!

At a depth of 2,590 meters, this requires a guy who can withstand 300 atmospheres to be reliable, and this will be the most advanced deep-water anti-submarine torpedo, and the maximum working depth seems to be 800 to 1000 meters.

As for the deep-water anti-submarine mines, they are even shallower, and the books I have read say that the maximum working depth seems to be only 3 or 500 meters.

I can't count on standard equipment, I can only hope for special equipment!

The question is: where to look?

Even if such a technology exists, the controller must not hide it as a treasure!

After turning his mind, Zhang Nan didn't have a particularly good idea for the time being, but he also had a general direction: small countries and weak countries are excluded, and the United States should not expect it, even if such technology exists, it is still in the navy.

With the attitude of the United States towards explosives, high-precision technology, don't even think about it!

Britain, France and Germany may be able to do the same thing in Europe, but without that friendship, even if there is friendship, it is unlikely to give it.

Even if they will give, won't people come to get a piece of the pie?

Does Huaxia have this technology?

Forget it, even if there is, don't bother to ask, it must be a secret on the line, it's too troublesome, and it's likely to be thankless.

Then there is only one place left: Russia!

Thinking of this, Zhang Nan said into the microphone: "I'll find a way, you have been floating on the sea for a long time, and you are going to find a suitable port nearby to rest first."

By the way, you have calculated the number and power of the bombs you need, and let me know as soon as possible.

Wait for my news, even if you can find it, nine times out of ten it is not finished, and God knows when it will be shipped over. ”

Two thousand tons of silver, even if you can get half of it, the price can now be hundreds of millions of dollars, if the price is not big, you can try it, the company needs.

Jamie Bostvik on the other end of the phone smiled and said, "We are relatively close to the coast of Oman now, just over a hundred nautical miles away, but we will go to the Emirate of Fujairah in the United Arab Emirates."

It is more convenient, it is the entrepot of the US President's Steamship Company, and our company has signed an agreement with the other party to make it easy to use the port facilities that they have invested in Fujairah, and the UAE and Fujairah also welcome American ships to call at the port, and the cost is low. ”

Zhang Nan didn't care about the specific operation of these subordinate companies, and let the salvage company and Jack make their own decisions.

Hung up the phone and saw Andrei pouring himself a drink at the bar, so he asked him: "Andrey, there is one thing, do you know if Russia has the technology to blast underwater at a depth of 2,500 meters?"

You can blow up, blow up the hull of a sunken ship. ”

Andre was actually paying attention to the boss's phone, and then said, "Yes, at least two."

The first one I have heard is that it is used for deep mining of hot springs, which is more than 1,000 meters common, and it should be possible to do it at 2,500 meters, but it takes some effort.

Basically, it is a compression-resistant steel barrel stuffed with explosives and an initiator, which is detonated by wired remote control.

I don't know how to seal these, but there are factories that can make them, or civilian ones, and I can have people try to find and contact them.

But it's still time, maybe a bomb can be done for tens of thousands of dollars, but it's normal to wait for a month or two.

Transportation is more troublesome, even if it is air and sea, it will take a lot of time to reach the Arabian Sea. ”

Zhang Nan couldn't help it, but as soon as Andre said it, it was two!

I haven't heard of it, but I can't help it, but it turns out that people actually have such a trick that can be used in civilian technology.

"What's the second one?"

Andrey took a small sip of vodka, today is the New Year, he is not on duty, he came to play, it is normal to drink.

"It's faster and more expensive.

Now Russia should mothball and eliminate a lot of unmanned deep submersibles, several of which can reach a depth of three or four thousand meters, and the remote control equipment can also match our salvage ships.

Even if it is eliminated and sealed, it can almost be used, but because it is not used at all now, and the maintenance fee cannot be paid.

Many of those deep submersibles have their own payload, and if you find one or two cables and batteries for dual-purpose power supply, the batteries will be smaller, and they will not take dozens or hundreds of hours of working time.

The vacated battery space and payload are equipped with high-energy explosives, and when the time comes, the boss can blow up as much as you want, but it will cost hundreds of thousands of dollars with a sound, which is slightly expensive. ”

Slightly expensive?

It's not expensive!

This is the "improved super-deep line-guided torpedo" that is only useful under special conditions, and it is this speed that is so slow that the speed of ordinary unmanned deep-sea submersibles is only a few knots, and it cannot be counted on for naval warfare.

But this time it is appropriate to use this method to blow up the hull of the sunken ship!

Hundreds of thousands of dollars a shot, it's really not expensive.
