At the Combined Naval Event (CNE) in Farnborough, UK (May 19–21, 2026), FarSounder demonstrated what a genuinely fused maritime perception stack looks like in a single operator interface. The showcase centered on SonaSoft LT, the company’s navigation software platform, now integrating four distinct sensing layers simultaneously:
- FarSounder Argos 3D Forward-Looking Sonar — real-time underwater hazard detection ahead of the vessel (submerged obstacles, shallow water, bottom topography)
- SEA.AI — above-water AI-powered optical detection of vessels, debris, and other surface contacts
- Tocaro Blue ProteusCore — AI-powered radar perception, providing radar track data fused directly into the navigation picture
- AIR & ARPA targets — conventional radar tracking integrated alongside the AI-derived contacts
The result is a common operating picture that spans the water column: from the seabed ahead, through the surface, to radar-range contacts — all rendered in a single interface with nautical chart overlays, saved depth readings, and aerial imagery.
Why This Matters for Naval and USV Programs
The significance of this demonstration is not any single sensor — it is the integration architecture. Each of the four sensing layers is a separate vendor’s product, and FarSounder has built SonaSoft LT as the fusion layer that ingests all of them. This is precisely the kind of open, composable architecture that the Navy’s MUSV Marketplace and broader autonomous surface vessel programs are demanding: no single vendor owns the full stack, and capability can be layered in as it matures.
FarSounder’s Argos sonar line is already qualified for USV applications down to vessels under 15 meters (the Argos 350 is the standard fit for smaller platforms), and the company has been advancing ASV/USV-specific navigation capabilities since at least 2021. The CNE 2026 demonstration represents the most complete public display of that roadmap to date.
The Tocaro Blue integration — announced May 14, 2026, just days before CNE — is particularly relevant. Radar perception has historically been a weak point in autonomous maritime navigation: conventional ARPA radar produces tracks but not the semantic understanding needed for autonomous decision-making. Tocaro Blue’s ProteusCore adds AI classification on top of radar returns, giving the autonomous system the ability to distinguish vessel types and assess collision risk rather than simply tracking contacts.
For programs like the Navy’s MUSV Marketplace (where seven companies are currently in at-sea testing for a potential $15M completion payment and follow-on production) and DARPA’s Deep Thoughts AUV program, the sensor fusion architecture FarSounder is demonstrating at CNE is directly relevant to the technical requirements those programs will need to satisfy.
