KraitArray Sonar System

SEA has developed the advanced KraitArray sonar system; a configurable thin line (16mm) acoustic array comprising 32 channels, that provides a 50m acoustic aperture.

Unmanned Warrior 16 (UW16) proved the capability of KraitArray as a passive Anti-Submarine Warfare (ASW) sensor with a range of capabilities; as part of bi-static systems; as a communications aperture and in detecting threats from submerged and fast surface craft. 

SEA was instrumental in developing ASW deployment patterns and tactics for UW16 to enable Surface, Air and Underwater  unmanned systems from; Boeing, Liquid Robotics, Autonaut, Ultra and SAAB, to co-operate and maintain an ASW barrier in the waters off the Outer Hebrides.  During UW16, Unmanned Surface Vehicles with the KraitArray have proved the capability to deploy and maintain an effective ASW barrier for protracted periods in conditions up to Sea State 6.

The ASW demonstration during UW16 was a milestone achievement for the KraitArray sonar system, as it gave the UK Royal Navy considerable insight into the potential for unmanned systems to contribute to integrated ASW capabilities in the future.

SEA Product Manager Alex Key explained: “The initial feedback from UW16 has been extremely positive. KraitArray is at the forefront of low weight, low power towed sonar systems that can be used for a wide range of commercial and military applications including ASW, torpedo detection and border surveillance. We continue to work on incremental technical developments that will further extend the system’s capability.”
