The Gemini S5 USV is purpose-built for extended uncrewed tactical operations in maritime environments. It is optimized for area patrol, surveillance, and remote engagement of both surface and submerged targets, with multiple weapon integration options.

Up to twelve Gemini S5 platforms can operate within a 200 km radius from a shipboard or coastal command-and-control (C2) base, supported by Zevs H12 VTOL unmanned aerial systems equipped with EO/IR sensors, maritime radar, AIS receivers, and MANET communication relays.

The system supports both surface and underwater target detection through integrated SONAR capabilities. For extended mission range, Gemini S5 can be equipped with the Starlink High Performance LEO satellite terminal, delivering up to 50 Mbps upload and 400 Mbps download. Starlink also functions as a repeater hub, enabling a global mesh network between USVs and Zevs H12 UAVs — extending communications beyond 150 km in EVLOS conditions.

Constructed from epoxy-impregnated fiberglass with Kevlar reinforcement and a carbon-fiber RF-diffusing layer, the Gemini S5 is engineered for ultra-low radar visibility — remaining undetectable by conventional maritime radar at distances over 2 nautical miles.

The hull features integrated composite bulkheads for enhanced structural rigidity, closed-cell polypropylene foam for buoyancy in case of damage, and redundant ejector pumps for survivability. All hatches are reinforced and sealed to prevent water ingress during rough sea states or capsizing.
