Fan Wuxian personally sent Masha and Katya back to Russia. Not only because it shows the importance it attaches to this matter, but also because Russia has begun to officially salvage the Kursk.

In order to ensure that the salvage of the Kursk nuclear submarine can proceed smoothly, the Russian Ruby Central Marine Design Bureau has developed a large-scale simulated salvage test program. According to Valentin Pashin, academician of the Russian Academy of Sciences and president of the Krylov Central Scientific Research Institute in St. Petersburg, the simulated salvage test has ended.

Pashin said that in the past, experts from the research institute were in full swing to use a large number of models of the Kursk nuclear submarine to conduct simulated salvage tests, and these models with a length of two or three meters were all made according to the test requirements.

The Krylov Central Scientific Research Institute has its own nautical base, where specialists complete a wave simulation operation for the salvage of the Kursk nuclear submarine. In addition, they have recently tested whether the towing device and transport equipment of the salvage nuclear submarine are strong and reliable.

In May of this year, the Russian side officially signed an agreement with the Dutch company Mamut on the salvage of nuclear submarines. According to the agreement, the salvage work will be completed by 20 September this year.

This time, Fan Wuxian sent Masha and Katya back to Russia, just to visit the cooperation team of CCTV and New Silk Road Entertainment Company, which has already launched a team in the Barents Sea, to see what the actual situation of salvaging the Kursk is.

As a big creditor of Russia and the financier of the salvage of the Kursk this time, Putin attaches great importance to the arrival of Fan Wuxi, especially when he specially sent his two daughters back, and this favor is inevitable to be repaid.

So, Putin specially hosted a banquet for Fan Wuxian in the Kremlin and sent a special person to send him to the salvage site of the Kursk.

Submarines are often remembered for carrying a wealth of advanced military technology, and salvaging a wrecked submarine is definitely a great opportunity to get close to core military secrets. As a result, in the process of salvaging wrecked submarines, the struggle between secrecy and theft of secrets, whether overt or covert, between military science and technology, often occurs.

Last August. The Russian nuclear submarine Kursk unfortunately sank at the bottom of the Barents Sea, and none of the 118 people on board survived. In order to recover the bodies of the officers and men who died and to protect the secrets on the boat from leaking, Russia decided to salvage the wrecked submarine and announced that the salvage work would be carried out through international bidding.

Western countries were overjoyed when they heard the news, the Kursk is Russia's most advanced missile nuclear submarine, and it usually does not have the opportunity to see the true face of Lushan.

Speaking of which, Western countries have coveted the Kursk for a long time.

One is the details of the sound-absorbing material on the surface of the hull. A layer of unique sound-absorbing material is laid on the surface of the boat, which can greatly reduce the noise of the submarine during submersion and enhance the concealment. However, what kind of material is this and what kind of effect it can achieve, the details are not known to outsiders.

The second is the Granite long-range supersonic anti-ship cruise missile. This is the most headache for the Americans with the killer weapon of the aircraft carrier. It can skim the sea at a cruising speed greater than twice the speed of sound, attack surface ships within a range of 20 to 550 kilometers, and has an anti-jamming capability and defense penetration capability that is unparalleled.

The third is the storm high-speed torpedo, which is the prototype of the blizzard torpedo that Fan Wuxi made before. In the eyes of Westerners, this perverted weapon is simply an underwater missile, capable of flying underwater at a high speed of more than a hundred knots. When attacked by it, the ships may not even have time to react, let alone evade, and no country is not moved by such advanced torpedo technology.

In order to keep the secret, Russia has taken even greater pains.

On Putin's orders, the Northern Fleet dispatched a large mixed fleet of more than a dozen ships, led by the heavy nuclear-powered missile cruisers Peter the Great and Marshal Uskinov, as well as five helicopter gunships and two transport planes of naval aviation, into the predetermined area.

Russian President Vladimir Putin also said that the wrecked sea area of the Kursk nuclear submarine is a no-sail zone, and who dares to trespass. Russia will be unceremonious, in order to let the countries with evil intentions take their words seriously, Russian President Putin also ordered the Northern Fleet to regularly repeat this message to other countries by radio, and authorized his own warships to carry out preventive blasting in the no-sail zone on a regular basis, eager to blow up the designated area to the sky.

Despite the aggressive actions of the Russian side, there were still uninvited guests who broke into the restricted area.

On one occasion, Admiral Koravchenk, chief of staff of the Russian Navy, inspected the salvage work by helicopter. When the helicopter flew over the Severomorsk anti-submarine ship, which was on guard in the operation area, a foreign naval helicopter actually passed by the general's plane.

Obviously, this helicopter was using the general's plane as a cover to conduct aerial reconnaissance of the salvage work of the kukboat. The general was indignant at this, and he remembered the audacity of a foreign reconnaissance ship and a sonar detection ship at sea not long ago, and these two ships ignored the warnings and got closer and closer to the sunken sea area of the Kuboat, and the Russian frigate repeatedly drove them away, until the guns were put on their heads, and the two ships reluctantly left.

With these previous convictions, Russia has a tighter eye on the Kursk nuclear submarine, and ordinary people can't approach it at all, even the joint film crew of CCTV and Fan's Investment Group, which has been given the right to interview, must strictly abide by the regulations of the Russian side, and close-range shooting is obviously not allowed.

Two days after arriving at your destination. The Norwegian deep-sea salvage mothership Regalia on which they were traveling finally arrived at the site of the sinking of the submarine Kursk.

The weather was good, the sea was calm, and for the first time, Fan Wuxian and others had the opportunity to see the absolute protagonist of this salvage operation that attracted the attention of the whole world.

Russian, British and Norwegian divers, in addition to Russian military divers, Norwegian divers from Helabton Petroleum, the Norwegian branch of the American oil company.

During the interview, Russian diver Petrovsky was the first to say what was in his heart, "The difficulties and dangers we face are too great, and anyone who says that they are not afraid is a lie." ”

According to Petrovsky, divers from Russia, Great Britain and Norway dived in batches, with two Russian divers and one foreign diver in groups of three. Their first task was to cut through the walls of the thick Kursk submarine and forcibly open a passage to the interior of the submarine.

This is not an easy task, unlike other modern large nuclear submarines in the West, the Kursk nuclear submarine has two thick hulls, filled with a full 20 centimeters of rubber in the middle. The purpose of such a facility is to absorb the mechanical sounds emitted by submarines, making it difficult for enemy sonar systems to pick them up.

However, this design undoubtedly made it difficult for divers, who had to use high-pressure water cannons and diamond steel drills to forcibly cut through the hull, and then forcibly tear off the rubber protection with the help of a crane on the surface.

On the surface, the purpose of this salvage operation is, of course, to recover the bodies of the officers and soldiers killed in the Kursk.

Whenever a dive team is working on the bottom of the sea, the other divers stay in the pressurized chamber of the Regaria mothership, ready to dive for shifts or to deal with sudden dangers.

Divers breathe helium mixture when working on the bottom of the sea, which can affect people's pronunciation, so the sound transmitted back to the surface by divers when working on the bottom of the sea is particularly sharp and a bit weird.

However, what the divers are most afraid of is not the difficulty and danger of the salvage operation, but the psychological test they face, and the unexpected encounter with the dead in the submarine in the dark.

Petrovsky told reporters, "You think about it, in the darkness where you can't see your fingers. How should you suddenly come face to face with a body that has been blown up and deformed in the sea? Then, even if you drag, carry or carry the corpses out of the submarine, that's not all, because getting them to the surface is also a matter of care, depressurizing them little by little, and if they float too fast, the corpses will be crushed by the pressure in their bodies. When you think about it, you know what kind of mental endurance divers need. ”

"There are also some experts who believe that it is impossible for us to find the bodies of the officers and soldiers who were killed," the British diver said. Why, because looking for a corpse in a dark submarine cabin is like looking for a needle in a haystack, to be specific, the light on each diver's head can only shine at a distance of four or five meters, and the volume of the Kursk is 10,000 cubic meters. What's more, two-thirds of the 118 officers and men on board the Kursk stayed in the weapons room and control room at the bow of the submarine, and they were killed on the spot when the explosion occurred, and their bodies were estimated to have been blown to pieces, so the divers most likely recovered about 20 percent of the bodies. ”

Before starting to cut the Hull of the Kursk, the most important task for the divers was to try to find out if the inside of the Kursk was safe, that is, whether there was a leak in the two nuclear reactors on board.

If the radiation in the submarine exceeds the standard, it means that the plan to salvage the bodies of the dead officers and soldiers will have to be completely abandoned.

To do this, the divers drilled a small hole in the sturdy hull of the eighth compartment of the Kursk submarine, the nuclear reactor compartment. Then I put the camera and the radiation detection needle in.

Divers and field commanders were relieved that the reactor chamber was well equipped, no anomalies were found, and the radiation detection needles showed that the radiation levels were normal.

A spokesman for the field in Norway said, "From the preliminary test results, the water samples obtained in the eighth compartment show that there is no leak in the nuclear reactor, but it cannot be ruled out that there are leaks in the other compartments." ”

A Russian spokesman for the field said, "Water samples taken from the eighth compartment show that the seawater inside is pure seawater and there is no danger." ”

Divers collected water samples in small containers and handed them over to two Norwegian radiation experts on board the mother ship for identification. Judging by the results of the identification. Obviously, drilling can be carried out.

According to the plan, if you want to explore the 154-meter-long hull of the Kursk, you have to drill at least seven holes in the Kursk submarine, each of which is an average of two meters square, and it takes at least 15 hours to cut each hole.

Today, however, the cutting of the outer hull went very well, and it took only ten hours for the outer hull to be cut through a large two-metre square opening. Due to the anxiety of some journalists, media around the world have reported that divers will be able to enter the Kursk, but the reality is still far from it.

The next day was cold and the sea was stormy, and the divers had to suspend the hull cutting operation. The successful cutting of the outer hull was very exciting to the divers and the Russian naval commanders on the scene, who were ready to cut open the inner hull of the Kursk in one fell swoop.

A Russian naval officer who participated in the construction of the Kursk submarine at the scene told Fan Wuxian while watching the TV picture from the bottom of the sea, "The divers are really amazing, you must know that the inner shell of this submarine is made of specially reinforced steel, and it is not easy to drill the inner hull in the shipyard under normal circumstances, but they have actually drilled ten centimeters, which is really amazing." ”

Fan Wuxian smiled, didn't say anything, in fact, he was a little disappreciative in his heart, after all, it is easy to destroy and difficult to build, and people will always have many ways to do it.

Just after dark, the head of the rescue department of Russia's Northern Fleet, General Virich, announced the temporary suspension of night operations, because the wind that had been blowing all day had intensified enough to threaten the lives of divers.

So far, divers have completed a fifth of the cutting tasks, and it seems that it will take some time to cut a hole that can be safely accessed by divers, who left the cutter on the submarine hull before returning to the surface.

The third day was again cloudy, and there was a storm at sea, and the commander of the Russian Navy reserved the right to cancel the operation at any time.

However, the suspension of the operation instead gave CCTV and the joint film crew of Fan an interview with the commander of the Russian Navy, Vladimir. Admiral Kuroyedov had the opportunity to further understand the dangers faced by the divers.

Due to the violent explosion in the bow of the Kursk submarine, most of its internal structure is believed to have been blown to pieces, and most of the heavy equipment in the stern compartments is believed to have been shaken everywhere, which makes the divers enter the interior of the submarine as if they are entering a labyrinth, and every step forward may be fatal.

As they navigate the inaccessible submarine, the fragmented submarine equipment and sharp iron frames threaten to tear the divers' pressurized suits or cut their air supply pipes. Any kind of danger can kill the diver.

For this, Admiral Kuroyedov sincerely praised the divers, saying, "This salvage operation is an unprecedented challenge in terms of technological innovation, courage and psychological factors. ”

There are no pop-ups
