Twenty kilometers away, when the huge mushroom-shaped fireball rose from the sky, Lin Han was twenty kilometers away, sitting alone on a submarine numbered U571 to enjoy the scene.

Fearing the radiation damage to the divers caused by the large amount of radioactive dust caused by the nuclear explosion, all human crew members were forbidden to stand on the submarine and watch the scene of the nuclear bomb being exploded at an altitude of 500 meters above the head of the U.S. fleet.

After the second nuclear explosion, the warships around the entire waters of Artura Island were in chaos, and the mobile anti-submarine patrol ships and air defense alert ships that were originally located on the periphery were all in a state of confusion and confusion in which communications were cut off and they could not contact their superiors. There are also a large number of flaws in the originally tight protective patrol network. In the area where U571 is now driving, there are no destroyers within a dozen kilometers around, and you can safely surface (crab) to drive. Farther away, there were a number of U.S. destroyers, but they were all at full speed, frantically moving away from Artura Island to escape a possible third nuclear strike.

Sitting on the boat, after Lin Han said this sentence to Hannah, a female figure appeared out of thin air on the surface of the boat, and Hannah also came out.

As soon as she appeared, she stretched out her hand to Lin Han, and the hands of the two joined in the air, and soon the two of them merged into one person, and then disappeared into the boat platform out of thin air.

A few seconds later, the high-powered radio station on the submarine began to work, sending out radio signals to guide the sky that was approaching the Soviet nuclear attack aircraft group to correct its course and approach the target.

After a high-yield nuclear explosion, radio communications will be strongly affected for a short period of time. However, if you only guide the aircraft within a few tens of thousands of meters overhead, you can still be contacted.

The third round of nuclear strikes by the Eurasian coalition against the US fleet on the island of Atura was carried out fifteen minutes after the second atomic bomb was dropped. And it came again.

A Tu-4 strategic bomber, escorted by several TA154 night fighters, dropped a third Soviet-made atomic bomb with an explosive yield of 80,000 tons over the man-made port on the island of Artura at 4 a.m.

The third hurricane was still raging, and only ten minutes later, another Tu-4 strategic bomber flew over the U571. Five minutes later, a fourth sun rose over the island of Artura.

Although the fourth nuclear bomb was dropped by Soviet Tu-4 bombers, it was made by China. In order to "save" nuclear bombs. New China directly used its first nuclear test in actual combat, with the US Pacific Fleet as the target of the experiment.

In less than two hours, the tiny island of Artura ate four atomic bombs in a row. The total equivalent is close to 300,000 tons!

"Summer is here. It's mushroom harvest season again! ”

On the U571 submarine, the egg-sore Lin Han issued this telegram to the whole Pacific Ocean in clear code, and after dawn, the telegram was published on the front page of newspapers all over Europe.

After the Battle of Guam, the U.S. Navy was in the process of rebuilding, and by 1946, a total of 12 fleets had been formed, 10 of which were placed in the Pacific Ocean. In the early hours of the Fourth of July. Four fleets are being deployed on the island of Artura, and the remaining four are also in the waters of the Aleutian Islands. Only the 4th and 8th fleets were repaired and maintained on the west coast of the United States.

The huge fleet stationed on the island of Artura was scattered in three artificial harbors on the island at that time. If it weren't for the saturation of the harbor with ships, the need to guard against the Combined Eurasian Fleet in the south, and for the sake of "conservative" security, President Dewey, who was so overjoyed, would have almost cram all eight Pacific Fleets remaining in the western Pacific here.

When the Atura Islands were hit by a nuclear attack, the remaining four Pacific Fleets, the Fifth, Sixth, Ninth, and Tenth Fleets, were scattered in the waters off Kiska Island to the east of Artura Island, and because of the distance between the Soviet land-based airfields, they were fortunate to escape this round of nuclear strikes by the Eurasian coalition forces.

The U.S. Navy's 1st, 2nd, 3rd, and 7th Pacific Fleets stationed on Artura Island were the key targets of the nuclear strike that night.

On 4 July, the National Day of the United States, according to President Dewey's "pretending" plan, 20 Essex-class aircraft carriers, eight Independence-class aircraft carriers, all four Iowa-class battleships, and the USS Montana, the general flagship of the Pacific Fleet, were moored on Artura Island, in addition to 20 cruisers, more than 180 destroyers, 34 escort aircraft carriers, and more than 200 other auxiliary ships. It can be said that forty percent of the combat strength of the US Navy is concentrated here.

Since the three ports of population on the island of Atula are separated from each other and have a certain interval between them, in order to ensure the maximum effect of nuclear strikes, coalition planes dropped three enhanced atomic bombs with a yield of more than 80,000 tons on the three ports in the form of airdrops in about 32 minutes, ensuring that each port will receive one.

The main reasons why the three atomic bombs were not dropped at the same time were that the three dropping points were close to each other, the risk of throwing them was high, and the technical difficulty of detonating them was high, and the second was that the time points of the atomic bombs were too close to each other, and the impact of the nuclear explosions would conflict with each other, which would weaken the effect of the strike.

In two hours, swallowing four atomic bombs in one go, the defenders and the fleet stationed on Artura Island suffered a fatal blow.

MacArthur, who had escaped the first nuclear attack in an underground bomb shelter, did not escape the second nuclear attack. The second nuclear bomb was detonated 550 meters above the harbor, about 1,500 meters away from where his bomb shelter was, and MacArthur, who was "watching the scenery" outside the bomb shelter, was directly blinded by the light radiation generated by the nuclear explosion, and then the shock wave of the nuclear explosion directly blew his body without a trace.

Another commander of the US Navy's Pacific Fleet, Halsey, did not escape the catastrophe.

An atomic bomb with an 80,000-ton yield exploded right above the head of his fleet.

If he had been commanding in his flagship Montana at the time, the Montana captain's room with more than 200 millimeters of horizontal armor and 400 centimeters of side armor could have withstood the shock wave and radiation of a nuclear explosion from a distance of 1,000 meters, and he might have escaped death.

It's a pity that he was on a thin-skinned cruiser. When a nuclear eruption occurs, he looks up at the sky through the porthole.

The intense flash of the nuclear explosion burned Ha Guangxi's eyes at the first time, and then the shock wave of the nuclear explosion. Smashed the porthole and rushed into the command room. The crushed glass shards hit Halsey in the face like bullets, and the bodies of all the personnel in the command room were pierced like sieves, plus light, heat, and nuclear radiation, and all of them died.

After swallowing four mushrooms, the garrison on Artura Island was almost completely killed and wounded, and a very lucky few barely escaped that day. Suffering from intense nuclear radiation, they could not escape the torture of radiation damage, and they went from dying immediately to dying after a month of painful struggle.

A handful of personnel from the command center who escaped the four nuclear bombings by hiding in a fortified bomb shelter. It is also inevitable to die.

According to the data of the "crossroads" nuclear explosion test that occurred on Bikini Island in "history", Lin Han's family decided that they would completely annihilate the US fleet here by attacking Artura Island with only four nuclear bombs before the nuclear strike. Theoretically impossible. (The striking effect of a nuclear bomb on the fleet.) I have already said it in the previous chapters, so I will not repeat it)

According to Lin Han's point of view, it doesn't matter if all enemy ships cannot be "nuclear sunk," and it is also possible to achieve the strategic goal of completely annihilating this fleet by killing and scrapping as many sailors on the ships as possible.

The first way of killing and injuring human beings with protein bodies by a nuclear explosion is the "physical direct attack" of light radiation, nuclear radiation, and nuclear shock waves during the nuclear explosion, while the second is more terrifying, which is that the nuclear dust produced after the nuclear explosion is absorbed into the human body and causes various types of nuclear radiation sickness.

Lin Han's family, who lost their conscience. All the bombs dropped on the island of Artura were "refueled" "off-offspring bombs" -- cobalt bombs!

Each nuclear bomb shell is coated with a special layer of cobalt, and all four of these bombs are cobalt bombs. The cobalt bomb is also considered one of the most "dirty" nuclear bombs.

A certain amount of ordinary cobalt (Co59) is placed around the explosives in a nuclear bomb. When a nuclear bomb explodes, the neutrons produced in the nuclear reaction convert cobalt-59 into the radioactive isotope cobalt-60, which returns to Earth in the form of dust and contaminates the ground. Cobalt-60 decays into nickel-60 and emits gamma rays of 1.17 with a value of 1.33 MeV. Its half-life is 5.27 years, which gives cobalt-60 enough time to propagate and maintain sufficient radiation intensity, and because the half-life is too long, it is difficult for the attacked person to wait until the radiation is over, even if he hides in bunker.

The gamma rays emitted by cobalt-60 are extremely penetrating, and even in thick steel hulls, the weakening effect on them is very poor. Historically, this concept was first developed by physicist Leo Brown. Proposed by Szilard on February 26, 1950, claiming that a batch of cobalt bombs could wipe out all human beings. His aim was not to create such a bomb, but to illustrate that nuclear weapons technology would soon reach the level of annihilating the entire human race.

Of the four nuclear bombs detonated by the Lin Han family on the island of Artura, the most powerful was the first, and the "dirtiest" was also the first.

Since it is a "primitive" means of detonating a submarine beach, it is possible to manufacture it without considering the load problem. In order to increase the power and "pollution" effect, you can frantically install all the things you can think of to increase pollution on this nuclear bomb.

After the four nuclear explosions, the US Navy officers and sailors at the center of the nuclear explosions, those survivors, more or less inhaled deadly nuclear dust, which will soon cause nuclear radiation sickness in their bodies.

No matter how strong a warship is, it needs a healthy sailor to maneuver.

Although the 1st, 2nd, 3rd, and 7th Pacific Fleets, which suffered three air-blast nuclear strikes, still had a large number of warships stubbornly floating on the surface of the sea and did not sink directly, this fleet has been abandoned.

The five battleships moored in the harbor all survived the nuclear explosion and did not sink on the spot. But all the warships were damaged to varying degrees.

The most serious damage was the destruction of vulnerable parts such as radar and optical sighting equipment on the surface of the fleet, and the destruction of secondary artillery and anti-aircraft artillery with insufficient armor protection. The high-heat and high-temperature impact caused by the nuclear explosion also detonated some of the ammunition piled up in the open air of the hull, causing certain losses.

The powerful nuclear shock wave hit the warship's hull, which also caused a certain degree of deformation and damage to the ship's hull, and in addition, the portholes of all warships in the military port were shattered.

The damage caused by the three nuclear strikes to the four Iowa-class battleships did not "break their muscles and bones", but directly abolished their "five senses". All kinds of sighting equipment and radar equipment were completely destroyed, and these five battleships actually lost the capability of long-range artillery warfare. The destruction of the secondary anti-aircraft guns made these warships weak and powerless in the face of air threats, and they could only be slaughtered.

In addition, another fatal point lies in the fact that during the nuclear explosion, a large number of "faithful" sailors went to work on the upper echelons of the warship, and as a result, they faced the flash of the nuclear explosion, and the lucky ones were directly killed by thermal radiation, light radiation, and shock waves, and the "unlucky" ones were blinded on the spot, and then endured the torture of radiation sickness in the coming time.

The five battleships withstood the "test" of a nuclear strike with their thick skin and rough flesh, but the other warships in the harbor did not have this "good fate."

The heaviest losses were those auxiliary ships and destroyers that made the explosive heart. After the three nuclear explosions, nearly 100 such ships sank directly or ignited as a result of the nuclear explosions, turning them into eye-catching torches floating on the sea.

Twenty Essex-class aircraft carriers and seven Independence-class aircraft carriers were all severely damaged in the nuclear explosion. Twelve of the Essex-class aircraft carriers and four Independence-class aircraft carriers were extremely seriously injured. Although they had not yet sunk immediately, fires were on fire on each of the ships, and damage crews were desperate to salvage the damaged ships. The decks of these aircraft carriers were all badly damaged and completely incapacitated before the shipyard overhauled. As for those Casablan-class aircraft carriers, they were also extremely damaged in the nuclear explosion, 20 of the 34 aircraft carriers were severely damaged in the nuclear explosion, and 12 of them were sunk or in the process of sinking or in the process of igniting fire.

Four nuclear attacks in less than two hours, completely abolishing these four fleets, but this is not the end, but only the beginning.

In July, the sun rises above the horizon on the island of Artura, located at high latitudes, very early, around 4:10 a.m.

At 4:40 a.m., when the U.S. fleet, which had been tragically attacked by a nuclear attack, was struggling with the aftermath of the nuclear bombing, a dense buzzing sound could be heard over the island of Artura.

A large number of four-engine heavy bombers, which took off from the island-based airfield of the Komandor Islands of the Soviet Union before the first nuclear explosion, appeared at the head of the American fleet. The four-engine heavy bombers, half of which were German ME26 (Crab)4 and the other half of which were Soviet Tu-4 bombers, entered the skies over Artura Island in batches.

In the belly of these four heavy bombs, there is a special aircraft bomb of the same kind: HS293, the first air-to-ship missile in human history to be used in actual combat. (To be continued......)
