SEAQUEST® 420 is a cost-effective and attritable 4.20 m semi-rigid unmanned surface vessel to deliver agile, reliable and rapidly deployable maritime capabilities for both defence and civilian applications.

Compact and easy to operate, SEAQUEST® 420 can be deployed from shore or from a mother ship with minimal operational constraints. Its lightweight semi-rigid architecture combines robustness, maneuverability and ease of integration, making it an efficient solution for extending operational reach while reducing the exposure of manned assets..

At the core of the platform is SIRSEA®, Sirehna’s dronization and remote operation system. Fully integrated from the design stage, SIRSEA® provides advanced teleoperation, command and control, and mission management capabilities, enabling safe, responsive and efficient remote operations in demanding maritime environments..

Built on a modular architecture, SEAQUEST® 420 can accommodate a wide range of mission payloads to support surveillance, reconnaissance, inspection, force protection and maritime security missions. Its versatility, operational simplicity and optimized life-cycle cost make SEAQUEST® 420 a smart and effective force multiplier for modern naval and maritime operations.
