A series of biomimetic submersibles independently developed by China have started practical deployment in the South China Sea, with larger variants for armed reconnaissance missions under development, media reported.
Developed by a team at the Northwestern Polytechnical University of China with complete intellectual property rights, the soft-bodied submersibles imitate the manta ray, or devil fish, China Central Television (CCTV) reported on Sunday.
Six variants in the series ranging from an operating weight of 10 kilograms to 720 kilograms have been built since 2006, CCTV reported.
ViWorld Timesdeos show that the submersible swim naturally just like a manta ray.
