Minewarfare systems

Drawing on vast expertise, Thales designs and integrates complete mine countermeasures systems. Wideband and SAS synthetic aperture sonars can detect and locate even the stealthiest mines.

As integrator of over half the world’s in-service fleet of Mine hunters, our added value is in our understanding of Mine Warfare operations, and the coherence of our MW systems: not only do we detect, classify, identify mines and mine-like objects, but we assess and measure MW risk, and quantify confidence that there are no mines remaining.


The TSM 2022 MkIII Hull Mounted Sonar utilises Sea-proven wideband technology directly derived from French, Dutch and Belgian CMT Class MCMV refit programmes. It offers Compact 3D stabilization gear fully compatible with existing platforms, most modern data processing and operator aids. TSM 2022 Mk III  is equipped with the latest technology necessary to counter the modern mine threat in difficult environmental conditions like shallow waters.

The mandatory requirement of the DUBM44 / TSM 2054 SAS is to make the routes safe from the mine threat. So the CONcept of OPerationS (CONOPS) is the following:

to achieve regular surveys with a very high resolution specific MCM SSS which maps the sea bed

to compare the new SSS/SAS images with reference SSS/SAS images

if a suspicious object is discovered, to assign a Mine Counter Measure Vessel (MCMV) with HMS for exploratory and if necessary clearance tasks.
