The US Navy has developed an autonomous robotic fish

The Navy is testing its shark-like ‘Ghostswimmer’ unmanned underwater vehicle at Joint Expeditionary Base Little Creek this week. It is one of a handful of programs being brought to life by the Navy’s innovative Rapid Innovation Cell. The project is called ‘Silent Nemo’ and it is aimed to put real-world unmanned tactical capabilities into systems that mimic organic species. The five foot long, 100-pound Ghostswimmer moves much like a large fish, and has been used to collect data on tides, currents, wakes and weather conditions.
