Oshen unlocks £3.6m in funding led by Lunar Ventures to scale ocean-sailing robots built for navies and weather agencies

Oshen builds C-Star constellations, swarms of 1.2-metre wind- and solar-powered robots that sail the open ocean for months at a time and transmit data by satellite. The vessels give navies, weather agencies and ocean scientists real-time information about waters that would otherwise go unwatched, from vessel activity near subsea cables and pipelines to the ocean heat that drives hurricane intensification.
