Hydrogen-fueled drone submarine with 17 sensors could scan Hormuz for naval mines

Euroatlas unveiled Greyshark, a hydrogen-powered autonomous underwater vehicle built for long-endurance missions.

The submarine carries 17 sensors and can reportedly patrol for up to four months.

It is designed for subsea surveillance, mine detection, and monitoring contested waters such as the Strait of Hormuz.

The system could help navies reduce risk by collecting intelligence without sending crewed vessels into dangerous areas.
