The submarine will …
Penn State University researchers have made progress on shielding large objects from sound. Chinese researchers have also published substantial progress on cloaking from sound. Both might lead to submarine sonar stealth. Chinese researchers presented the design, architecture and detailed performance of a three-dimensional (3D) underwater acoustic carpet cloak (UACC). The proposed system of the 3D …
China confirms that are testing an electromagnetic railguns on a navy ship. Zhang Xiao, associate research fellow at the Wuhan-based PLA Naval University of Engineering, led a team to develop repeating pulsating direct current power system that could charge the railgun. The same team solved technical issues for shipborne electromagnetic launching systems that will be …
Russia in a speech by Putin claims it has a new nuclear reactor that is 100 times smaller than those used by nuclear-propelled submarines and generates more power. The reactor can also reach its peak power 200 times faster than a conventional nuclear power plant The miniaturization of a nuclear reactor will give Russia another …
China might have a nuclear-powered aircraft carrier in the water by 2025. China Shipbuilding Industry Corporation (CSIC), which refitted China’s first aircraft carrier and built its second confirmed that a nuclear-powered aircraft carrier was in the works.
