Deploy anywhere. Survey everything

SQ18, powered by FLANQ, extends hydrographic capability beyond dedicated survey vessels. Deployment from mission bays, small craft or slipways allows naval units to establish seabed awareness quickly, supporting navigation safety, amphibious planning, mine-warfare assessment and Rapid Environmental Assessment without delaying operational tempo.

Survey with confidence

Configured with a multibeam echosounder, precision navigation and autonomous sound-velocity profiling, SQ18 delivers repeatable bathymetric data for cartographic production and operational decision-making. Autonomous mission execution improves survey efficiency while reducing risk to personnel in constrained or contested waters.

Versatile deployment

Deploy from naval vessels, mission bays or slipways with minimal crew and supporting infrastructure.

Survey-grade data

Combine multibeam sonar, precision positioning and autonomous profiling to produce reliable hydrographic information.

Multi-mission platform

Support hydrography, reconnaissance, Rapid Environmental Assessment and scientific missions from one adaptable USV.
