World War II:The wreckage of an American ship in the depths of the ocean, which 'looked as if the ship was still fighting'

Survivors report that a captain of a Japanese ship saluted the sinking American ship as it was disappearing into the waves.

In 1944, during World War II, the USS Johnston sank in the largest naval battle ever fought in the world.After more than 75 years, the wreckage of the ship has been discovered at a depth of six kilometers above sea level.

On October 23, 1944, the largest naval war in modern human history began in the Gulf of Latvia along the Philippine Sea.Over the next three days, more than 300 US warships competed with about 70 Japanese ships.

The Americans also had 34 aircraft carriers, which is less than the number of carriers in the world today. There were about 1,500 aircraft on these 34 ships. The U.S. Air Force had a ratio of one to five compared to the Japanese.

Despite being hit by shells, Johnston continued to fight for two more hours, raining down artillery shells on large enemy ships.The wreckage of most sinking ships is found in shallower waters. This is because ships sail on trade routes close to ports so that if the weather gets bad, coastal waters are their refuge. So this is where most ships sink.

But the water in which Johnston drowned was a very different matter. Instead of sinking near a nearby shore, it sank deeper into the ocean.Summer Island is located on the shores of a vast ocean valley called the Philippine Trench. It stretches for about 820 miles (1,320 km) along the coasts of the Philippines and Indonesia.

The sea is very deep here. If you place Mount Everest at Galathia Depth, the deepest point in the Philippine trench, its peak will still be underwater at a depth of more than one mile (1.6 km).One of the ships that sank was the USS Johnston. At seven in the morning, Johnston was hit by a Japanese ship, the Yamato.

His efforts kept Japanese naval ships away from light-armed American aircraft carriers.After two hours of continuous fighting, Johnston was hit by dozens of Japanese Navy shells. Surviving crew members clung to the rear of the wreck.

Eventually, the ship sank, including 186 of the 327 crew members. Survivors report that a captain of a Japanese ship saluted the sinking American ship as it was disappearing into the waves.

But the story doesn't end there.

The deepest parts of the ocean where life is extinct

No one knows how long it will take USS Johnston to reach the bottom of the ocean. It sank into the depths of the Philippine Sea, with some of the coldest and most difficult places, where life is scarce.

When you go 100 meters (328 feet) deep in the sea, the sunlight starts to decrease there. When you go down another 200 meters (656 feet) the light goes out.
This is a vast layer about a kilometer deep which indicates the end of the effect of sunlight on the sea.
As the ship sank, the temperature dropped further. At 1,000 meters (3,280 feet), Johnston's broken hill would have sunk into deep water just a few degrees above freezing, which marine experts call the 'Bathal Zone', also known as the 'Midnight Zone'.

No plants or plants grow here because sunlight cannot reach that low. Life does not exist in this deep frozen area, only aquatic animals can survive here in the dark and extreme cold.The average depth of the world's oceans is 3,688 meters (12,100 feet), which is more than two miles deep.

It is as deep as the water in which the ill-fated Titanic sank on its maiden voyage in 1912. But Johnston's "Death Dive" went much deeper.Going further below 4,000 meters (13,123 feet) is the Abyssinian Zone, where the water temperature is around freezing point and only three-quarters of the dissolved oxygen at sea level remains.

But the sea is deeper than that.

The fish found here look as small as the fish that swim near the surface. But they are also soft and slippery when touched. Some of these aquatic creatures are blind and some are almost transparent, meaning you can see through them.

The water pressure is so strong that most creatures cannot live here. Unlike their shallow aquatic creatures in almost every way, fish have antifreeze in their blood to keep them flowing even in extreme cold, while their cells contain special proteins that give them intense water pressure. Help to resist which would otherwise crush them.

Further down is the Huddle Zone (or Hades), another layer 6,000 meters (19,685 feet) below the water's surface. The huddle zone is found in deep ocean trenches and mostly in the Pacific Ocean, where giant tectonic plates push each other under waves.

The term was coined by Anton Friedrich Brown, a Danish maritime expert, in the 1950s, when technology was advanced enough to make the first careful search of these submarines. The term huddle comes from the ancient Greek god Heads of the underworld. This zone is in complete darkness, the temperature is close to freezing point, and the pressure is about 1,000 times higher than sea level.

This is where the lower part of the Philippine trench emerges in the deepest part of the zone. Many of the points measured along its length are about 10,000 meters (32,808 feet or 6.2 miles) deep, and its lowest points are 10,540 meters (34,580 feet) deep above sea level.

Somewhere in this vast trench or gorge under water, USS Johnston was finally buried. But its exact location was difficult to determine.

The sea level is by no means deformed, but because the oceans are not named after different places, finding the right places for naval battles can be a daunting task.

There are no memorials to the site of this battle, and there are no topographical features of mapping like Earth that help identify. In addition, the large currents flowing under the ocean waves can carry the wreckage of a ship far away from the place where it sank.
