China tests submarine cable cutter at 3,500-metre depth

A Chinese deep-sea mission has efficiently examined a complicated machine able to chopping by underwater constructions comparable to submarine cable at a depth of 1000’s of metres.

The “Haiyang Dizhi 2” analysis vessel accomplished its first deep-sea scientific mission of 2026 on Saturday, based on the Ministry of Natural Resources.

The expedition included a chopping check of a deep-sea electro-hydrostatic actuator at a depth of three,500 metres (11,483 ft), utilizing know-how that has drawn consideration for its potential military use.

“The sea trial has bridged the ‘last mile’ from deep-sea equipment development to engineering application,” the official China Science Daily reported on Saturday, suggesting the tools was poised for precise deployment.

An electro-hydrostatic actuator, or EHA, integrates the hydraulic system, electrical motor and management unit right into a single compact machine, eliminating the exterior oil piping typical of standard programs.
