Mastered with ease
Built simple and intuitive. No specialists or multi-week training required. Make waves without delays.
Priced for scale
Affordable enough to buy without extra procurement red tape. Produced at speed, with immediate stock and data-as-a-service available.

Detect from miles.

Captures complete intel
High-resolution data for maritime domain awareness, intelligence and surveillance missions, and subsea mapping.
Choose from our library of 50+ payloads, or add yours in hours
A modular payload system allows a library of payloads to plug and play in minutes. Other payloads added in hours or days.
Detects up to 6 months
Each vessel is hybrid-fueled for missions up to 6 months. Operational at sea state 6 conditions and during GPS denial.
Forms ocean-wide networks
The vessels' low cost permits their use at scale, covering vast geographic areas.

React at once.

Sends real-time alerts
Data alerts delivered straight to the cell or email of key decision makers. Immediate action can be taken.
Inspects or intercepts
Cue your sensors or move in for a closer look. Scramble a manned response or Quickfish for rapid interception or inspection.
Deploys drones
Built for UAS integrations, each vessel can launch drones to gain a top-down view or for a show of force. Compatible with Group 1 and Group 2 UAS.
Creates escort buffers
Quickfish can protect the perimeter of vessels and infrastructure, intercepting and escorting anything that enters their space.

Lightfish

Our flagship autonomous vessel. Light. Simple. Modular. Extremely effective. A satellite at sea for gathering vast ocean intelligence without the cost or complexity of a crewed expedition.

The vessel, in brief

Lightfish offers range and resilience—six months, 8,000 nautical miles—on solar-electric power with hybrid reserve. Rugged and self-righting, it operates in seas up to state 6, with collision avoidance, GPS-denied navigation, and redundant comms for global reach. Most payloads bolt on and plug in in minutes. Portable enough to launch by hand and simple enough to be used by anyone.

Quickfish

Tactical, agile and swift. Launches in seconds. Operates for days. A rapid response vessel for intercepting or interdicting maritime threats.

The vessel, in brief

The Quickfish permits speed on water and land alike. Its COTS design makes it fast to build and quick to maintain. Its simplicity means it takes just 3 days training. And its powerful propulsion means it can exceed 35 knots. Launched remotely from dock or mooring, it can monitor, intercept and ID anywhere from ports to oceans. Its internal drone platform can extend its presence and capabilities for closer inspections or as a show of force.

Swift
Sprints 35+ knots. Cruise 400+ nm.
Modular
Payloads swapped in minutes. C2 interoperable.
Rugged
Operational in Sea State 6 conditions.
Reliable
Resilient to GPS jamming and spoofing, with anti-tamper capabilities available.

High speed aluminum hull

Unmanned and unmatched

Choose between a high-speed diesel propulsion drive or a gas jet drive for shallow water and anti-foul operations. Aluminum plate construction allows for low tooling assembly. Holds long range radar and EO/IR sensors. A modular payload bay enables aerial launch capabilities. Combined, these make Quickfish as affordable as it is effective.

Heavyfish

The mighty. Built for power, endurance, and adaptability. Can tow payloads such as heavy acoustic arrays up to 1000 pounds, travel for months on end, and cruise up to 12 knots.

Expected Splash Date: 2026

The vessel, in brief

The Heavyfish is built on the proven foundation of its sibling vessels, providing additional brawn, speed and payload possibilities, for wider use cases and added flexibility. Pairing electric and diesel drive into a single propulsion unit for lasting performance and endurance. Just as rugged, modular and simple as its siblings. Ideal for MDA, ASW, sonar surveys, harbor security and HVU escort.
