Zero USV Launches Oceanus12 XLR to Extend Endurance and Operational Range

Zero USV has unveiled the Oceanus12 XLR, an extended-range variant of its earlier Oceanus12 uncrewed surface vessel (USV), originally launched earlier this year. While maintaining the hybrid-electric propulsion platform, the XLR significantly boosts endurance through a larger fuel tank and extended hull dimensions, making it well-suited for missions exceeding 25 days or 2,500 nautical miles.

The new XLR model measures 13 metres in length, compared to the original 11.55 metres, and holds up to 4,000 litres of fuel—more than triple the base model’s 1,200 litres. Despite the increased size, payload capacity remains unchanged at up to one tonne.

“Uncrewed vessels are a force multiplier. The ability to conduct sustained operations at sea without the need for regular refuelling or crew-related logistics is becoming increasingly crucial as operational pressure on resources and time become more demanding,” said Matthew Ratsey, Founder and Managing Director of Zero USV.

“This is even more pronounced as international tensions rise, particularly in regions with contested maritime boundaries, heightening the need for reliable, high-endurance long-range USVs. In fact, they’ve never been more critical.”

The Oceanus12 XLR comes equipped with the GuardianAI autonomy suite from MarineAI, and includes a fully autonomous sensor package with high-definition radar from Navtech. A remote control mode is also available to support flexible mission profiles.

The vessel’s sensor bay is designed to be modular and sensor-agnostic, supported by a quick-change keel system that allows preconfigured sensor modules to be swapped out with minimal downtime.

To maintain stable and safe operation in long-range and remote deployments, robust marine cabling plays a key role. Systems such as the hybrid drive, autonomous navigation, radar, and data links require consistent power and signal integrity. In similar applications, marine-rated cables compliant with BS 6883 (for armoured power and control cables) and BS 7917 (for low smoke, zero halogen cables) are typically specified to ensure flame retardancy, mechanical strength, and resistance to moisture, oil, and vibration.

The Oceanus12 XLR displaces eight tonnes with a draft of 1.76 meters. Propulsion is delivered via a twin electric hybrid system with software-limited installed power of 40 kW, upgradable to 80 kW. The vessel cruises at 6 knots and can reach a sprint speed of 10 knots, depending on payload and sea conditions. Solar charging supports house loads and emergency systems.

Designed for long-range deployments where access to traditional fuelling infrastructure is limited, the Oceanus12 XLR supports a range of mission types, including surveillance, environmental monitoring, and strategic defense operations in contested or remote maritime zones.

Most recently, Zero USV announced that Leeway Marine has become its first international franchisee, providing charter services for the Oceanus USV fleet across North America.
