The National University of Defense Technology has long been deeply engaged in national key research projects spanning the development of underwater intelligent equipment, collaborative operations of unmanned underwater swarms, and deep-sea environmental sensing. It boasts world‑class research capabilities in overall system design, intelligent control, and system integration for underwater platforms. During the practical implementation of these projects, research prototypes and experimental test rigs urgently require specialized underwater pressure‑rated housings that deliver high performance, exceptional reliability, and adaptability to a wide range of operating depths. At the same time, stringent requirements are imposed on dimensional accuracy, pressure‑resistance ratings, waterproofing levels, lightweight structural design, and customized configurability—criteria that off‑the‑shelf sealing products cannot readily meet, given the demanding standards of military‑industrial research and testing.
In response to the pain points of deep-sea equipment connectors—reliance on imports, insufficient reliability, and high maintenance costs—a certain military unit has put forward a demand for domestic substitution, requiring compliance with operational performance criteria of 1,000 meters water depth, five years of maintenance-free operation, and zero failures. Against this backdrop, Hesi Technology, leveraging its technological expertise in precision manufacturing and materials R&D, has entered into a strategic partnership with the First Academy of China Aerospace, drawing on its profound capabilities in military equipment R&D and reliability management, to jointly advance the development of this domestically produced waterproof connector.
