To mark the start of Euronaval, Euroatlas and EvoLogics have announced the commencement of series production of their autonomous underwater vehicle, the Greyshark. The system has been designed for reconnaissance, surveillance, mine countermeasures and the monitoring of critical underwater infrastructure.
At the naval exhibition in Paris-Nord Villepinte, which opened on 3 November, the companies are presenting the first production vehicle. According to the manufacturer, orders from European government customers have already been received. The Berlin-Bremen partnership expects the first deliveries to take place before the end of the year. Naturally, details regarding customers, production figures and order values remain undisclosed.
The exhibition, which runs until 6 November, is traditionally an occasion for product launches, cooperation agreements and announcements regarding development progress. Unmanned systems are once again among the key topics. On the opening day, KNDS and SeaOwl announced a collaboration to develop and test an armed surface drone. Following its acquisition of the Canadian specialist International Submarine Engineering, Elbit Systems is showcasing the latter’s underwater vehicles for the first time as part of its expanded maritime portfolio.
These announcements thus represent different stages: a development partnership, the expansion of a product range and, in the case of “Greyshark”, the reported transition to series production. Whether these will result in permanently available military capabilities will be determined following delivery, acceptance and deployment by the users.
From prototype to series production
“Greyshark” made its debut at Euronaval 2024. The system, approximately six metres long, is designed for reconnaissance, surveillance, mine countermeasures and the monitoring of critical underwater infrastructure.
For the battery-electric version, the manufacturers quote a range of around 300 nautical miles at four knots and a mission-dependent operational duration of three to five days. A fuel-cell variant, designed for greater range and longer endurance, was already unveiled in March 2026.
Several vehicles are to be able to exchange data via encrypted underwater acoustic communication and allocate tasks autonomously. The current press release does not contain any details on the actual annual production capacity. When the Foxtrot variant of the ‘Greyshark’ was unveiled in March 2026, the manufacturers had indicated a production capacity of 150 units per year, stating that an increase in production to up to 500 units annually was feasible. The extent to which these capacities have since been established remains unclear.
