Jane's has covered Oshen's participation in Royal Navy-funded Atlantic Net Defence trials off Iceland, where a C-Star successfully deployed a hydrophone to detect maritime assets up to 10 nautical miles away — in storm conditions. Read how Oshen's small, affordable, sail-powered USVs could form the backbone of a persistent acoustic screen across the GIUK Gap, and why our CEO Anahita Laverack believes a constellation of 1,000 C-Stars could be deployed and operational in under a year.

In a world first, Oshen's C-Stars sailed directly into the eyewall of Hurricane Humberto — a Category 5 storm. Becoming the smallest uncrewed vehicles ever to collect and transmit key oceanographic and atmospheric data from inside the hurricane. Working alongside NOAA and the University of Southern Mississippi, the C-Stars recorded gusts exceeding 150 mph and air pressure readings significant enough to be cited in NOAA's official forecast discussion. "This opens up the possibility of more routine use of C-Stars for hurricane data collection in the future in support of hurricane research and forecasting."- Greg Folz, NOAA AOML.

In 2024, the Met Office verified the performance of a fleet that had gathered data from a particular storm. ...The comparisons between measured and modelled parameters were excellent, showing real promise for robots being the future of climate monitoring.

Under the Forecasting Tipping Points Program, Oshen will deploy a 50 strong fleet of robots to create a unique early warning system in the North Atlantic Sub Polar Gyre (NA-SPG). The Oshen-SWARM will improve both local and global forecasting and modelling.

Plymouth-based start-up has deployed a constellation of five C-Star autonomous sailboats into the Atlantic's "hurricane alley" as part of NOAA and the University of Southern Mississippi's 2025 hurricane monitoring programme. The wind-powered robots have already successfully gathered and transmitted live data from Hurricane Gabrielle. Oshen CEO Anahita Laverack said the technology has the potential to save lives by improving forecast accuracy, and that future deployments of hundreds of C-Stars could transform how hurricanes are monitored — all while keeping costs under control.

"Developers of the Oshen C-Star envisage “picket lines” of 1,000 eco-boats – powered by wind and solar energy – being deployed in the strategic area between Iceland, Greenland and Britain. The drones would be able to support the Navy’s eight new [Type 26 submarine-hunting frigates](https://www.telegraph.co.uk/news/2025/07/14/the-disastrous-type-26-programme-british-navy-defence/), which are set to join the fleet in the 2030s."

Oshen's CEO and co-founder Anahita Laverack sat down with Startups Magazine to tell the story behind Oshen. Read how a passion for sailing and a frustration with outdated data collection methods sparked the idea for a technology that could one day put affordable, real-time ocean data in the hands of anyone who needs it — from climate researchers to offshore wind developers.

No one has yet been able to sail an autonomous boat across the Atlantic, but a young couple in Wales hope their craft will revolutionise ocean monitoring of temperatures, wildlife and more.
