SIGURD Mine Countermeasure System
Modular mine search, detection, and neutralization support built on the S6 Class.
Find the Mine. Close the Mission.
Mine countermeasure operations do not reward complexity.
SIGURD is a modular MCM system built around the S6 Class. Deploy it for search and detection. Configure it for neutralization support. Field one component, or combine both into a complete mine countermeasure workflow.
The system is man-portable, platform-flexible, and built for contested maritime environments where standoff, autonomy, and operator control all matter.
Search the area. Confirm the contact. Act when required.
Built for the MCM Kill Chain.
Search and Detection
SIGURD executes structured search patterns across designated lanes at operational depth. Side scan sonar payloads support detection of seabed anomalies, moored mine contact points, and mine-like objects in known or suspected threat areas.
Contact Reporting
When a contact is identified, SIGURD generates mission data for operator review, follow-on tasking, or post-mission analysis. The system supports TAK-enabled workflows, web-based mission planning, and API-based integration into external C2 systems.
Retasking and Inspection
Operators can adjust mission parameters, assign follow-on inspection, or continue the search pattern based on contact data and mission priority.
Neutralization Support
When configured for neutralization missions, SIGURD supports autonomous transit, terminal sensing, camera-assisted inspection, and mission-specific payload integration. Operators select the engagement mode based on mission requirements.
Platform-Flexible Deployment
Launch from shore, small craft, USV, or platform of opportunity. No large support footprint. No slow deployment cycle.
Attritable at Scale
Mine countermeasure systems need to be fielded in numbers. SIGURD is built on a compact, manufacturable UUV architecture designed for scalable deployment.
Choose the Mission Package.

One platform. Multiple outcomes.
The Numbers
What Ships With SIGURD
* Final configuration depends on mission package, payload selection, and customer requirements.
Where It Works
Mine Countermeasures
Search, detection, localization, and neutralization support for mine-like objects in contested maritime environments.
Port and Harbor Clearance
Survey restricted maritime zones, anchorages, piers, approaches, and high-value port infrastructure.
Littoral Access
Support route survey and threat reduction in shallow, complex, and contested waters.
Expeditionary Operations
Deploy from small craft, shore, USV, or platform of opportunity with minimal footprint.
Seabed and Near-Bottom Survey
Detect mine-like objects, contact points, and anomalies along the seafloor.
Post-Engagement Re-Survey
Support follow-on survey and confirmation workflows after operator-authorized action.
Built on the S6 Class. Ready for the Water.
SIGURD uses Vatn’s S6 architecture: compact, modular, and designed for field deployment at scale.
The S6 Class has been integrated across multiple unmanned surface launch concepts, tested in open-water environments, and built around the navigation, autonomy, and C2 architecture used across Vatn systems.
Mine countermeasure missions require more than a vehicle.
They require a system that can search, report, retask, and support action under operational pressure.
