Neptis
Integrated unmanned maritime surveillance system
Neptis is a modular system-of-systems for persistent maritime surveillance across ISR, ASW, critical undersea infrastructure protection, C-UAS and early-warning missions. It combines distributed autonomous assets, mission-specific sensors and integrated C2.
A new model of
maritime surveillance
Maritime security increasingly requires persistent, large-scale surveillance across strategic sea lanes, coastal approaches and critical undersea infrastructure. Traditional surveillance relies on deploying crewed ships wherever sensing is required.
Neptis changes this model by distributing autonomous sensing assets across the operational area, extending reach and persistence while preserving high-value ships and crews for higher-priority missions.

Extend surveillance reach
- Move sensing beyond the ship: Neptis distributes autonomous sensing assets across the operational area, creating complementary observation points above, on and below the surface and enabling multiple areas to be monitored simultaneously.
- Distribute your sensing capability: Deploy a single Oryx USV or build a coordinated multi-Oryx USV network according to the geography, threat environment and coverage required.
- Tailor sensing to the mission: Combine radar, EO/IR, AIS, EW and acoustic sensors to support ISR, ASW, CUIP, C-UAS and early warning missions.
From sensing to decision
PLAN & DEPLOY
Coordinate multi-Oryx USVs for persistent 24/7 wide-area surveillance.
DETECT & SENSE
Continuously monitor air, surface, electromagnetic and underwater domains through distributed autonomous sensing assets.
CLASSIFY & FUSE
Aggregate multi-sensor data for contact tracking and assisted classification within a unified Common Operating Picture.
SHARE & RETASK
Share mission information through resilient C2 links and dynamically retask assets as the situation evolves.
Deliver actionable intelligence
Turn data into tactical insight
Neptis C2 suite combines mission planning, platform supervision and coordination, and multi-sensor data visualization within a common operational environment. It helps operators build a clearer tactical picture and make faster, better-informed decisions.
Assess contacts faster
Data fusion and assisted analysis support contact detection, classification and tracking, helping operators focus on relevant activity.
Keep operators in control
Operators retain control of mission validation, platform retasking and operational decisions.

Operational contribution:
Extend detection coverage against low-flying aerial threats and provide earlier warning.
Sensor availability and compatibility depend on platform and mission configuration.
MAINTAIN PERSISTENT AWARENESS
Keep sensors on task for longer
With up to 30 days of endurance, Oryx platforms support persistent maritime surveillance, continuous monitoring and reduced reliance on continuously deployed crewed ships.
Maintain operations in degraded conditions
High-grade inertial navigation, onboard redundancies and configurable LOS/BLOS radio and satellite communications support Oryx USV operations when GNSS or communications are degraded. At system level, distributing sensors across several assets adds resilience, allowing surveillance to continue if one platform or sensor becomes unavailable.
CONFIGURE NEPTIS AROUND YOUR MISSION
Neptis is designed as an open, configurable system rather than a fixed platform-payload package.
Navies can combine assets, sensors, communications and supervision arrangements according to the operational effect required.
Select the right assets
Combine Oryx USVs with complementary autonomous assets, such as UAVs and other distributed sensing systems, according to the operating environment and required coverage. The Oryx family supports missions ranging from local surveillance to long-duration offshore operations, with different deployment, endurance and payload capabilities.
Configure mission payloads
Combine mission-specific sensors across available platforms according to the required surveillance effect and operating environment.
Configuration cover air, surface, electromagnetic and underwater domains.
Adapt communications and supervision
Configure LOS and BLOS connectivity, data flows and shore- or ship-based supervision according to mission geography and existing naval infrastructure.
Scale progressively
Start with a single Oryx USV and a defined use case, then expand toward coordinated multi-platform and multi-domain operations as requirements and doctrine evolve.
