What is the name of a Chinese submarine that has a 7 km to the sea

That's not called a submarine, it's a submersible. It's called "Jiaolong".

Related information: In 2002, China's Ministry of Science and Technology listed the development of deep-sea manned submersibles as a major special project of the National High-tech Research and Development Program (863 Program), and started the self-design and integrated development of the "Jiaolong" manned deep-sea submersible. From 2009 to 2012, Jiaolong successively achieved successful sea trials of 1,000 meters, 3,000 meters, 5,000 meters and 7,000 meters.

In July 2012, Jiaolong set a Chinese manned deep diving record of 7,062 meters in the Mariana Trench test sea area, and also set a record for the largest diving depth of similar operational submersibles in the world. This means that China has the ability to carry people to more than 99.8% of the world's ocean depths for operations. On December 18, 2014, Jiaolong went to the Indian Ocean for the first time.

On January 14, 2015, Jiaolong carried out the last dive of the first leg of the Indian Ocean scientific expedition in the Longyi hydrothermal area of the southwest Indian Ocean, which was also the ninth dive of the Jiaolong in this segment. After the completion of this dive, the "Jiaolong" will berth in Mauritius on the mother ship for replenishment, and then continue to carry out the diving and scientific research mission of the second leg of the Indian Ocean scientific expedition in the southwest Indian Ocean. On March 17, Jiaolong docked at the National Deep-sea Base Wharf on the ship "Xiangyanghong 09" and officially settled in Qingdao.

<>20,000 Leagues Under the Sea".

in the submarine.

It is the famous submarine Nautilus, which was secretly built by Captain Nemo on a deserted island in the middle of the ocean, with a sturdy hull and the ability to use the sea for energy, and they depend on the various flora and fauna of the ocean for their lives. Captain Nemo was also very kind to his captives, but he couldn't let them leave in order to keep the Nautilus's secrets.

Captain Nemo invites Aronnath on a journey to the bottom of the sea. Aronnath had no choice, so they set out from the Pacific Ocean, passing through coral islands, the Indian Ocean, the Red Sea, and the Mediterranean.

In the Atlantic Ocean, Dong Sen saw many rare animals and plants in the sea and the strange sight of Na Lu Mu. On the way, there were also many dangerous situations such as stranding, indigenous sieges, fighting with sharks, iceberg closures, and octopus attacks.

There is no record of who the captain Nemo really is in the book 20,000 Leagues Under the Sea, but later on the mysterious island.

In the book, it is explained that the captain Nemo was actually Indian.

The submarine in <>20,000 Leagues Under the Sea" is the famous submarine Nautilus, which was secretly built by Captain Nemo on a deserted island in the middle of the ocean. Captain Nemo was also very kind to his captives, but he couldn't let them leave just to keep the Nautilus's secret.

Captain Nemo invites Aronnath on a journey to the bottom of the sea. Having no choice, Aronnas set out from the Pacific Ocean, passing through coral islands, the Indian Ocean, the Red Sea, the Mediterranean Sea, and the Atlantic Ocean, where they saw many rare flora and fauna and strange sights in the sea. On the way, there were also many troubles such as stranding, indigenous sieges, fights with sharks, iceberg road closures, and octopus attacks.

China's 10,000-meter submarine is called the Struggler.

Struggler is a 10,000-meter manned submersible developed by China, which was established in 2016 and undertaken by a scientific research team based on the research and development strength of Jiaolong and Deep Sea Warrior manned submersibles. On June 19, 2020, China's 10,000-meter manned submersible was officially named Struggler.

On October 27, 2020, the Endeavor successfully dived more than 10,000 meters in the Mariana Trench to reach 10,058 meters, setting a new record for China's manned deep diving. At 8:12 on November 10, the Struggler successfully sat at the bottom of the Mariana Trench at a depth of 10,909 meters, setting a new record for China's manned deep diving.

At 8:04 on November 13, 2020, the Endeavor manned submersible successfully dived again to break through 10,000 meters in the Mariana Trench. At 7:44 on November 17, the Struggler dived again to break through 10,000 meters. On November 19, the Struggler once again broke through the 10,000-meter sea depth to review the scientific research operation capacity.

Submarine-type structure

The double-hull submarine hull is divided into an inner shell and a shell, and the inner hull is a steel pressure-resistant hull to ensure that the submarine can withstand the hydrostatic pressure corresponding to the depth when it is active underwater; The hull is a non-pressurized hull made of steel and does not withstand seawater pressure. Between the inner shell and the shell are the main ballast water tanks and fuel tanks. Single-hull submarines only have a pressure-resistant hull, and the main ballast water tanks are arranged in a pressure-resistant hull.

A half-hulled submarine with partially non-pressure-resistant hulls on both sides of the pressure-resistant hull as the main ballast water tanks of the submarine. The hull of the submarine is mostly streamlined (advanced submarines are generally designed to be drop-shaped or cigar-shaped) to reduce the resistance of underwater movement and ensure that the submarine has good maneuverability.

The pressure-resistant hull is usually divided into three sections: bow, amidship and stern, which are divided into 3 8 sealed cabins, which are equipped with control command positions and equipment, devices, various systems and crew living facilities, etc., to ensure the normal work, life and combat of the crew.

Modern submarines are equipped with large spherical sonar base arrays and torpedo compartments in the bow section, and 4-8 533-650mm Yushen tordo tubes are generally installed in the torpedo compartment. The amidships section has a pressure-resistant pre-leased command room and a non-pressure-resistant water command bridge.

Summary. Chinese submarines can dive to the bottom of the sea up to 7,000 meters.

Chinese submarines can dive to the bottom of the sea up to 7,000 meters.

The Deep Sea Warrior is a deep-sea submersible independently designed and built by China, which can dive into the deep-sea area at a depth of more than 7,000 meters, and is one of the deepest submarines built by China.
