China deep-sea cable cutter test at 3,500 meters is drawing global attention after a successful sea trial demonstrated the ability to cut undersea infrastructure at extreme depths. The test, conducted from the research vessel Haiyang Dizhi 2, reached nearly 11,500 feet below the surface, marking a significant leap in subsea engineering capability. Reports from South China Morning Post indicate the trial has “bridged the last mile” between development and real-world application.This breakthrough matters immediately because more than 95% of global internet traffic flows through undersea cables. Any advancement in cutting or manipulating these cables carries both industrial and strategic implications....
