Zero USV has expanded its portfolio of unmanned surface vessels (USVs) with the unveiling of the extra-long-range (XLR) Oceanus12, providing users with additional options for high-endurance maritime operations.
The original Oceanus12, launched earlier this year, is engineered to excel in missions lasting up to 20 days or 2,500 nautical miles. The new XLR version builds on the hybrid electric technology developed for the Oceanus12 and extends mission duration to an impressive 7,500 nautical miles, or approximately 60 days, without external support.
Designed for remote areas and regions with limited access to traditional fueling infrastructure, the XLR enables sustained, uninterrupted operations.
While maintaining the same power and onboard functionality as the core variant, the XLR Oceanus12 increases its overall length from 11.55m to 13m. The original version has a fuel capacity of 1,200 litres, supporting a 2,500-nautical mile range for 20–25-day missions. In contrast, the XLR carries 4,000 litres of fuel and can exceed 7,500 nautical miles, supporting missions of over 60 days.

Matthew Ratsey, Founder and Managing Director of Zero USV, stated, “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. 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 never been more critical.
“The Oceanus12 XLR is designed to meet these demands, offering unparalleled endurance for missions that require extended periods at sea, whether for surveillance, environmental monitoring, or strategic defence operations. By offering more flexibility and the ability to conduct longer missions, Zero USV’s XLR version responds directly to the strategic challenges of today’s global security environment.”
