[Big military news] The Chinese manned submersible "Struggle" successfully sat in the deepest in the world The Mariana Trench (10909 meters) has attracted attention at home and abroad.

10 years ago, in July 2010, my country’s first self-designed and integrated manned submersible "Jiaolong", with a diving depth of 3,759 meters, China became the second after the United States, France, Russia, and Japan. , The fifth country in the world that has mastered the technology of manned deep diving at a depth of 3500 meters; in June 2016, the "Jiaolong" completed its ultimate challenge-7062 meters.
3 years ago, on October 3, 2017, China’s second deep-sea manned submersible "Deep Sea Warrior" and the deep-diving test team completed all sea test tasks in the South China Sea. "Deep Sea Warrior" has an operating capacity of 4,500 meters underwater, with a higher degree of localization and greater practicability.

On November 10, 2020, the Struggle, which combines the fine pedigrees of the previous two generations of deep submersibles, won the Mariana Trench in one fell swoop (American undersea explorer Victor Vescovo claimed that the May 2019 He once dived to 10928 meters). The
Struggle uses a safe, stable and powerful energy system, a more pressure-resistant manned ball cabin and buoyancy materials, and is also equipped with a more advanced control system and positioning system.
and the "struggle" used a new domestic titanium alloy material, giving her the "super magic" to withstand the huge seabed pressure, this material has been optimized and tested thousands of times by scientific researchers before it came out.

Why are the world’s major powers obsessed with exploring the underwater world? In a word,
ranks among the global maritime powers. The paper "Development Status and Trends of Deep-Sea Manned Submersible Technology" written by Hu Zhen, deputy chief designer of
"Jiaolong", mentioned that deep-sea submersibles are an indispensable means of ocean exploration and resource development and utilization. To a certain extent, it marks the national marine resource exploration and development and even the protection of marine rights and interests and the level of science and technology. The development of this technology is not only of great significance for national economic and social development and national security, but also for the future use of marine space and marine tourism. Industry, deep sea salvage, life-saving, etc. have inestimable value and strategic significance.
Yes, there are 2 keywords mentioned here: "Marine Rights" and "National Security".

foreign media also pay attention to the "Fighter" number.
As we all know, the ocean area accounts for 71% of the world, and the mineral and energy reserves deep in the seabed exceed that of the land. This is not only a "cornucopia", but also a "big treasure basin" and a "treasure land". Human exploration and development here It is still far from enough, and even not much is known about it. To a large extent, the deep sea still seems so mysterious and unknown.
Exploring the ocean, protecting the ocean, managing the ocean, and building a maritime power will inevitably require high-tech deep diving equipment.
The deep-sea technology represented by the abyssal entry technology and the abyssal detection technology represents the top level of the current international deep-sea engineering technology field.
CNN issued an article on November 11, emphasizing the "competition for deep-sea resources". The
article mentioned that in a review article published by the Chinese official media, the author stated that deep-sea exploration is essential to better understand the “international strategic landscape”; Japan has discovered rare earths in the Pacific Ocean in recent years. Resources, it is said that its recoverable reserves are 1,000 times more than land; if we do not explore the underwater world, others will also explore.
The US media once again emphasized the importance of rare earths, whether it is civilian smart phones or military high-tech products such as missiles and radars, they are inseparable from rare earths. At present, most rare earth products are controlled by China, but they face severe competition from other countries in the world. In 2018, Japanese researchers claimed to have made a major "game-changing" discovery. Rare earths containing millions of tons of rare earth reserves were discovered in the deep ocean near Nantori Island (Marcus Island), a volcanic island in the Pacific Ocean. mud. In the same year, Reuters stated that India was preparingInvested more than 1 billion U.S. dollars in ten years to explore large areas of the seabed to find rare earth and other mineral deposits.
