China tests 'jellyfish shredder' to save aircraft carriers
China has tested its "jellyfish shredder" weapon aimed at protecting its fleet of aircraft carriers, according to reports. The system, towed by a tugboat ahead of the aircraft carrier, destroys jellyfish by chopping them into thousands of pieces. Jellyfish often get sucked into ships' water intake pipes and clog their cooling systems, bringing the vessels to a complete halt.
