In recent years, China has made remarkable progress in deep-sea exploration, with its three manned submersibles—Jiaolong, Shenhai Yongshi (Deep Sea Warrior), and Fendouzhe (Striver)—continuously setting new records and demonstrating the nation’s comprehensive capabilities in deep-ocean technology.Jiaolong, China’s first domestically designed manned submersible, reached a depth of 7,062 meters in 2012, setting a world record at the time for operational manned submersibles. In 2017, Shenhai Yongshi successfully completed sea trials at a depth of 4,500 meters, achieving high levels of domestic component integration, which significantly improved operational efficiency and reduced costs. Most notably, Fendouzhe, launched in 2020, surpassed the 10,000-meter mark by reaching 10,909 meters in the Mariana Trench—the deepest known oceanic trench—making China one of the few countries capable of full-ocean-depth manned submersion.These submersibles have not only expanded humanity’s understanding of the deep sea but also play vital roles in marine resource exploration, ecological research, and seabed geological surveys. Their successful development and deployment reflect China’s integrated innovation capabilities in advanced equipment manufacturing, materials science, and underwater acoustic communication, laying a solid foundation for the nation’s future deep-sea strategic scientific and technological ambitions.
近年来，中国在深海探测领域取得显著进展，三大载人潜水器——“蛟龙号”、“深海勇士号”和“奋斗者号”不断刷新纪录，彰显了我国深海科技的综合实力。“蛟龙号”是中国首台自主设计的载人深潜器，2012年成功下潜至7062米，创下当时同类作业型载人潜水器的世界最深纪录。随后，“深海勇士号”于2017年完成4500米级海试，实现了关键部件国产化，大幅提升了运维效率与成本控制能力。而2020年问世的“奋斗者号”更是突破万米大关，在马里亚纳海沟成功坐底，深度达10909米，标志着中国成为全球少数掌握全海深载人深潜技术的国家之一。这三台潜水器不仅拓展了人类对深海的认知边界，还在海洋资源勘探、生态环境研究及海底地质调查等方面发挥着重要作用。它们的成功研制与应用，体现了中国在高端装备制造、材料科学、水声通信等领域的协同创新能力，也为未来建设国家深海战略科技力量奠定了坚实基础。
