China has unveiled a compact deep-sea cable-cutting device that could sever the world’s most fortified underwater communication and power lines. The device was developed by the China Ship Scientific Research Centre and its affiliated State Key Laboratory of Deep-sea Manned Vehicles. The cable cutter targets armored cables layered with steel, rubber, and polymer sheaths that underpin 95 percent of global data transmission.
Although created as a tool for civilian salvage and seabed mining, the dual-use potential of the device raises significant national security concerns for other nations. The revelation of this technology underscores the strategic importance of subsea communication infrastructure. It may prompt other countries to reassess their own maritime security protocols and technological capabilities.
Chinese researchers from state-affiliated institutions claim the cable cutter is capable of severing heavily fortified communication and power lines at depths of up to 4,000 meters. This is nearly twice the depth of the world’s deepest undersea cable. The new design emerges amid growing concerns over the vulnerability of Taiwan’s critical infrastructure.
Deep-sea cable security concerns
Collin Koh, a research fellow at the S. Rajaratnam School of International Studies in Singapore, said while cable-cutting tools are commonly used for maintenance, the breakthrough in the ability to sever cables at record depths with great efficiency is alarming in the current political context.
The concern is that in the event of an invasion, China could sever the undersea cables around Taiwan. This could sow panic among its public and potentially disrupt the island’s military communication with the US and other partners. Koh pointed out that the new cable-cutting design may have existed so far only in the experimental stage.
“Whether it has translated into operationalized tool for use is a big question mark,” he said. The development of the deep-sea cable cutter comes alongside other Chinese maritime innovations that have captured the attention of defense experts. These include a chain of massive barges stretching from a Chinese beach into the sea, which could be used to deliver tanks, armored vehicles, and other heavy equipment in the event of an invasion of Taiwan.
The barges and cable cutter fuel concerns about China’s expanding military and technological prowess at a time when the ruling Communist Party is ramping up pressure on Taiwan. China already sends fighter jets and warships near the island almost daily and stages increasingly frequent military drills to intimidate what it calls “Taiwan separatist forces.”
