Xinhua News Agency, Sanya, November 28. The "Struggle" all-sea deep manned submersible successfully completed the 10,000-meter sea trial and returned successfully on the 28th.
Xi Jinping, General Secretary of the Central Committee of the Communist Party of China, President of the State and Chairman of the Central Military Commission, sent a congratulatory letter to extend his warm congratulations and sincere greetings to all scientific researchers who are committed to deep-sea equipment research and development and abyssal scientific research.
Xi Jinping pointed out in the congratulatory letter that the success of the "Struggle" development and sea trials marks my country's ability to enter the deepest part of the world's oceans to carry out scientific exploration and research, and reflects my country's comprehensive strength in the field of marine high-tech.
From the "Jiaolong" and "Deep Sea Warrior" to today's "Struggle", you have practiced the "rigorous and realistic, united and cooperative, dedicated, and bravely climbing" China with a rigorous and scientific attitude and courage to be self-reliant. The spirit of manned deep diving has set a model for technological innovation.
Xi Jinping hopes that all scientific researchers who are committed to the research and development of deep-sea equipment and deep-sea scientific research will continue to promote the spirit of science, bravely climb the peak of deep-sea science and technology, and work hard to accelerate the building of a maritime power and realize the Chinese dream of the great rejuvenation of the Chinese nation. The protection and development of the ocean continue to make new and greater contributions.
At the welcoming event for the return of the "Struggle" sea trial held on the 28th, Liu He, a member of the Political Bureau of the CPC Central Committee and Vice Premier of the State Council, read out Xi Jinping's congratulatory letter and delivered a speech via video connection.
He said that General Secretary Xi Jinping’s congratulatory letter fully embodies the great importance of the Party Central Committee on technological innovation and the building of a maritime power. It has pointed out the direction and put forward requirements for deep-sea science and technology work. It is necessary to in-depth study and understanding, and resolute implementation.
The "Struggle" fully mobilized and coordinated the scientific research forces of all parties during the development process, and successfully broke through a number of key technologies. This is an important milestone in my country's deep-sea scientific and technological exploration.
It is necessary to conscientiously summarize successful experience, vigorously promote China's spirit of manned deep diving, strengthen collaborative innovation of industry, university and research, accelerate the application and transformation of scientific research results, and promote more core technological breakthroughs and sustainable iterations.
Since the "13th Five-Year Plan", the Ministry of Science and Technology, together with the Chinese Academy of Sciences and China State Shipbuilding Corporation, has organized nearly a thousand researchers from nearly 100 scientific research institutes, universities, and enterprises to successfully complete the development of the Struggle after arduous research. Starting from October 10, 2020, the Struggle went to the Mariana Trench to conduct a 10,000-meter sea trial and successfully completed 13 dives, of which 8 times exceeded 10,000 meters. At 8:12 on November 10th, the Struggle created a new record of 10,909 meters for China's manned deep diving, marking that my country has reached the world's leading level in the field of deep manned deep diving.
