User Message: This week, China unveiled a new deep-sea cable cutter that could cut lines at depths of up to 4,000 meters. The cutter is designed for integration with China’s advanced crewed and uncrewed submersibles. The new device was designed and developed by the China Ship Scientific Research Center and State Key Laboratory of Deep-Sea Manned Vehicles. It is able to sever “armored cables,” lines with steel, rubber and polymer sheaths, which makes up the construction of the majority of cables that carry global data and communications.
