2025年我国载人潜水器应用水平持续提升

Core Viewpoint - China's manned submersibles are making significant progress in deep-sea exploration, with a focus on expanding operational capabilities and achieving new milestones in various marine environments [1][3]. Group 1: Manned Submersible Achievements - In 2025, the "Jiaolong" submersible successfully completed China's first descent in the Arctic ice zone, collaborating with the "Fendouzhe" submersible for dual operations [3]. - The "Fendouzhe" submersible, supported by China's first ice-capable mother ship "Tansuo 3," conducted the first manned scientific exploration in densely packed Arctic ice areas, expanding China's deep-sea capabilities from "full ocean depth" to "full ocean area" [3]. - The "Shenhai Yongshi" submersible performed the first coordinated operations with unmanned submersibles in the underwater cultural heritage protection area of the northwest slope of the South China Sea, leading to new discoveries in deep-sea archaeology [3]. Group 2: Operational Statistics - As of now, China's three manned submersibles have completed a total of 1,746 dives, with expectations to surpass 2,000 dives by 2026 [5]. - In 2023, the three submersibles are projected to complete a total of 314 manned deep-sea dives, indicating a continuous improvement in operational capabilities [1].
