About K4 MANTA

K4 MANTA is an all-electric vessel capable of travelling on the surface and beneath it. The biomimetic hull supports low-signature insertion, autonomous navigation and configurable sensor, communications and effect payloads for reconnaissance, screening, resupply and maritime strike missions.

The platform uses the Auterion operating system, open autonomy interfaces and resilient communications for supervised missions and fleet coordination. Kraken is developing 18-, 36- and 54-foot variants. The engineering prototype carries approximately 100 kilograms and supports deployment from shore or maritime assets.
