KATFISH is a survey package built around keeping the sonar stable while the vessel moves. Articulated tailfins and an autopilot stabilize the towbody; the winch, tow cable and launch-and-recovery system connect it to the vessel. Kraken offers compact USV and ISO20 handling arrangements for different host platforms.
The company’s feature sheet distinguishes 3 cm by 3 cm imagery available in real time from 2 cm by 2 cm post-processed imagery, with a listed 200 m range on each side. At the SEFINE RD-22 demonstration, Kraken reports that the live feed reached operators ashore for contact classification. Its subsequent MOU discusses further mission-planning and automatic-recognition development, rather than establishing that all of those functions were already operational.
Integration also includes storage and data movement: the sheet lists 28 TB topside storage, gigabit Ethernet and common survey exports including XTF and GeoTIFF. Maximum sensor figures do not establish the radio-link capacity or environmental envelope of a particular installation.

Use & integration
Recorded applications
Seabed survey and infrastructure inspection
Mine-like-object detection and classification
Uncrewed survey-system integration
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Kraken reports Q1 2026 SEFINE RD-22 and November 2025 ARCIMS demonstrations of autonomous handling and live sonar use. The May 2026 MOU proposes further mission-planning and ATR development. Literature differs on 5–25 m versus 5–30 m survey altitude; platform-qualified operating limits and delivery acceptance require confirmation.
Commercial availability
Commercially offered sonar and handling configurations; host-vessel integration and acceptance conditions are specified per programme.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
High-resolution towed synthetic aperture sonar can support undersea survey and seabed characterization where persistent underwater awareness is required.
The capability may contribute to northern maritime awareness when undersea survey and detection gaps are relevant; Arctic operating assumptions still require validation.
KATFISH Towed Synthetic Aperture Sonar may help teams working on Future submarine operational capability by contributing to maritime and undersea operations and detection and situational awareness.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
