An underwater drone was shown in London that can change its tasks thanks to AI
At the DSEI 2025 exhibition in London, the German company EUROATLAS presented its new underwater drone Greyshark. This is reported by Army Recognition.
The system was developed against the backdrop of the growing vulnerability of critical maritime infrastructure. It is noted that this was influenced by sabotage on the Nord Stream in 2022, as well as on submarine cables in the North and Baltic Seas. Thus, the task of Greyshark is to conduct surveillance, mine countermeasures and intelligence gathering.
The underwater drone is available in two versions: Bravo, which runs on lithium-ion batteries, and Foxtrot, which is equipped with a fuel cell system. Bravo is 6.5 meters long and weighs 3.5 tons, while Foxtrot is almost 8 meters long and 4.5 tons, respectively. It uses fuel cells produced by the automotive industry.
It is noted that the Foxtrot has an autonomy of up to 16 weeks, this version can travel underwater for up to 11,000 miles without surfacing. If it is stationary on the seabed, it will "last" for several months in working condition.
It is noted that the drone can also be charged using electromagnetic induction and is designed to operate at depths of up to 4,000 meters. Its speed is up to 16 knots (almost 30 km/h).
The system is equipped with a suite of 17 sensors, including synthetic aperture sonar, multibeam sonars, electromagnetic and optical sensors, and a laser imaging and measurement system.
There is also an artificial intelligence system that processes data, controls navigation, and adapts missions in real time. This means that Greyshark can independently, without human intervention, change its targets during the mission.
Communication with the surface is provided by a telescopic antenna. The system supports military communications, satellite navigation with protection against interference. In addition, acoustic modems allow data exchange at a distance of up to 10 nautical miles in the water. It is this ability that allows the use of swarm tactics, when several drones independently coordinate their work.
In May 2025, the Greyshark Bravo was first introduced in Asia at the IMDEX exhibition in Singapore. And in August 2025, EUROATLAS announced the integration of Greyshark into Rheinmetall's Battlesuite command platform. The company plans to produce 150 units annually starting in 2026, with NATO and its partners as the main customers.
It was previously reported that Sweden is developing unmanned mini-submarines to counter Russian threats in the Baltic Sea. The prototype is scheduled to be launched in 2026.
