Non-kinetic effects could involve the use of “soft kill” capture systems to

Vatn Systems disable threats, such as the Stingray in- truder interception net from Oceanetics.

This system deploys a rapidly expand- ing net across the path of an underwater vehicle, entangling and immobilizing it.

Other non-kinetic effects could involve activating prepositioned acoustic coun-

Kinetic effects could be delivered by interceptor vehicles such as the Skelmir

For static threats located during seabed survey operations, ROVs such as the VideoRay Defender can be deployed from patrol vessels or dockside launch points to investigate, or in the case of the Atlas Electronic Seafox, provide a single-sortie inspection, identi
