At Euronaval 2026, taking place from 3 to 6 November in Paris, RTsys Group is showcasing three new solutions designed to meet the evolving operational needs of naval forces: SEMA MK-III, SONADIVE MK-II and SONABLOW. The Group is also presenting a broader range of underwater technologies dedicated to mine countermeasures, anti-submarine warfare and seabed security.

Three new solutions for naval forces

Among the highlights of RTsys Group’s presence at Euronaval are three new developments:

• SEMA MK-III is the latest generation of RTsys’ recoverable acoustic training target for anti-submarine warfare. It features enhanced simulation capabilities, including magnetic signature simulation, satellite communication and helicopter recovery.
• SONADIVE MK-II is an advanced underwater system designed to support military divers in reconnaissance and underwater operations. It combines imaging sonar, navigation and real-time acoustic communication.
• SONABLOW is an encrypted underwater acoustic command system that enables the remote activation of neutralisation devices at distances of up to 4km, without the need for conventional electrical firing cables.

Alongside these new products, RTsys Group is showcasing a wider portfolio of solutions, including the DEFENDER ROV combined with the VIPER system, the NIKA autonomous acoustic surveillance platform, the COMET-MCM and NEMOSENS-MCM autonomous underwater vehicles, as well as electromagnetic measurement systems.

Underwater technologies serving naval defence

Based in Lanester, Brittany, France, RTsys Group brings together three complementary areas of expertise through its entities: RTsys Underwater Technologies, RTsys Monitoring Solutions and MAPPEM Geophysics.

Drawing on its expertise in acoustics, underwater robotics and electromagnetism, the Group develops and integrates technologies for a wide range of naval defence applications, including mine countermeasures (MCM), anti-submarine warfare (ASW), and the monitoring and protection of the seabed and critical underwater infrastructure.

With 125 employees, €25m in revenue in 2025 and an average annual growth rate of 20% since 2021, RTsys Group is pursuing its international development, with the ambition of reaching €50 million in revenue by 2030. The Group invests 15% of its revenue in R&D.
