Submarines all over the world are almost all circular cross-sections, which are inevitably designed to resist the pressure of sea water.

But among the modern giant submarines, the former Soviet Union has a Typhoon-class strategic nuclear submarine called the world's largest, which is a double-cylinder parallel design, and in fact, when the Soviets created this huge weapon that can destroy the world, at the end of World War II, the Japanese also did it.

It's just that at that time, the purpose of the crazy Japan to adopt the double chamber was to use the submarine as an aircraft carrier for the aircraft, and form a space on the wide hull deck that could be ejected and taken off and recovered!

A submarine aircraft carrier like no other in history!

When it comes to World War II and submarines, almost all people remember is the German Sea Wolf, and they have no impression of Japanese submarines at all, this is because there is a difference in the strategy of using submarines between the two countries, the Germans are fighting independently of each submarine, and the main goal is to attack Allied merchant ships to destroy supplies, so in the end they set a terrifying record of sinking a total displacement of 25 million tons, while the Japanese used submarines as support ships for surface ships, and assisted in attacking large warships in naval battles, so in the end they only achieved a total record of 900,000 tons.

Comparing the two, no one remembers the submarine forces of the Japanese.

But in fact, Japan was indeed one of the most productive and innovative countries in that era, with a displacement of 6,500 tons of giant submarines unique in the world, and at that time Japan had 62 of the 65 large submarines in the world!

So professionals remember the most brilliant 40-headed submarine aircraft carrier of the Japanese Navy!

However, in the later stage of the war, because the US submarines used a large number of attacks and transportation supply ships in the Pacific Ocean, they not only prevented the Japanese from transporting the looted goods from Asia back to China, but also blocked the transportation of raw materials for production, resulting in an extreme shortage in Japan.

But in all the documents, the numbers of these five giants are all arranged from Yi 400, Yi 401, Yi 402, Yi 404, and Yi 405, except for one 403!

The Japanese themselves explained that the plan for 403 was delayed and not put into production, but the real answer was that they had already sent the completed submarine to Southeast Asia!

This people, who are accustomed to lying, lie until they die!

Of course, Buck didn't know so much about the origin and history, he only understood that this was a huge Japanese submarine, and the Japanese inscription on the hull of the boat indicated the ownership, it was a huge submarine that he had never seen before, and he sighed that Japan was strong nearly a hundred years ago, but he only wanted to serve the mother who had suffered humiliation.

If you fall behind, you will be beaten, this is really a famous saying for the ages.

Stepping on the rusty U-shaped ladder, under the attention of the two girls on the shore, Buck climbed onto the bow of the huge boat almost parallel to the water, and there were still anchor chains on the left and right sides, indicating that he did not enter in a panic at that time, but walked back along the hull of more than 100 meters, during which he crossed a lot of yellow cloth military uniform bones leaning together, and some of them were only wearing white underwear.

The hollow skull looked at Buck very frighteningly, and Buck easily lit up the sides with torches, and observed that they were all cliffs and cliffs, and there was no supply equipment to even survive, then this rock crack was not a submarine supply station at all, it could be a simple haven or hiding point, hiding from the U.S. military planes that were already ubiquitous and dominant in the South Pacific at that time!

The wide submarine deck can even play basketball, the width of more than ten meters, in the center of the average submarine with only one conning tower, here is a huge hangar, a hangar that can be hidden by folding wing aircraft, of course, in Buck it looks like a missile launcher on a modern ship, and some modern American submarines will also make such a special miniature submarine hangar, in fact, the Americans' approach is to learn from this.

The hangar doors that stood on the deck, like the conical shape of a modern aviation rocket, were so heavy that Buck tried and didn't move at all, and he couldn't shake them for half a minute without using the oxygen cutting equipment, and the many entrances and exits of the submarine on the deck were also rusty and motionless, Buck could only pin his hopes on the bridge, look at the watch on his wrist that was already two o'clock in the middle of the night, and raise his voice to call out to the two girls After getting a response, Buck tried to climb the control tower that was not on the central axis.

Buck had seen the Black Sea Fleet's large submarines up close, even if it was a modern large nuclear submarine, the conning tower was still as narrow as an excavator operation room, and here, it was so spacious that it could walk sideways than Mu Tianbo's Pingjing Vito RV, and the Japanese, who may have been embarrassed in their own narrow country, finally found a feeling of three bedrooms and two living rooms on this submarine.

It's just that Buck's head poked over the railing and was surprised to see a skeleton in a high-class naval uniform, sitting on the command platform!

Then behind the bones, a huge round hatch opens to the inside of the giant submarine!

Buck, holding the torch, hesitated for half a second, choosing to look at the bones first.

Just familiar with the British and Russian Chinese, he obviously can't do anything about the full Japanese on the command platform, try the leather-wrapped notebook seems to be made of tarpaulin inner core, there is no sign of shattering, so he carefully closed it and put it aside, ready to take it back to his wife.

Looking back at the face that has turned into white bones, there are still a little traces of muscle tissue decay and weathering, and there is also air circulating in the cavity of the mountain that has been connected with the sea outside at certain times, so it generally does not form a mummy-like state, which is very scary, but Buck took it as a diorama, and did not touch the opponent's naval cap, black military uniform with golden ribbons, and boots, just looked at it and confirmed that this should be the supreme commander of the whole ship.

Because a nearly one-meter-long command knife leaned against the side of the bones, the black scabbard should be leather, the handle was carved and gilded, and the workmanship was exquisite, and it was a high-end product at first glance, but Buck only touched it and felt that there was no dust on it, so he didn't pick it up at all, but with such a small movement, the ribbon on the scabbard was cracked, and the handle of the knife smashed on the metal floor of the command platform, and there was an echo in the empty tomb-like cave cavity, and Buck immediately raised his voice: "It's okay, it's okay......"

As a result, Fang Lingying's voice was not loud: "You are busy with you, we are looking at the bones ......" It is estimated that her occupational disease has attacked, and Buck has a very eerie feeling, which immediately attracted Ye Mingjing's scolding.

Then turn around and put the torch close to the round hatch, Buck, who has many years of experience in handling corpses, tested the hatch mouth, and put aside the ventilation state of the humid environment for sixty or seventy years, and changed the water every day, and there was no miasma formed after the corpse decomposed, and after confirming that the flames had not changed at all, he began to slowly descend the rusty iron ladder......

The descent is slow and careful.

But after only seven or eight meters, Buck stopped moving, because under the firelight, starting from the aisle of the cabin where he was staying, there were gold bricks everywhere he looked!

The surface is slightly blackened and slightly rough, but each one is about the size of a brick!
