The Chinese Navy Is Building a Robo-Shark The fish-like undersea drone able to operate with a low acoustic signature at high speeds for reconnaissance and anti-submarine warfare. The U.S. Navy is by no means the only force that sees the incredible value undersea drones can provide commanders in terms of high-risk surveillance, clandestine targeting reconnaissance, countermine operations and of course unparalleled endurance. Many of them can launch from missile tubes built into host-ship manned submarines beneath the surface and operate with less risk of detection in hostile waterways less approachable by submarines. The Chinese Navy is now talking about its new “Robo-Shark” fish-like undersea drone able to operate with a low acoustic signature at high speeds for reconnaissance and anti-submarine warfare.
