Zero USV, pioneers behind the world’s first charter fleet for over-the-horizon unmanned surface vessels (USV), has announced the expansion of its portfolio with the introduction of the new extra-long-range (XLR) Oceanus12, offering users even more options for high-endurance maritime operations.

The original Oceanus12, launched earlier this year, is engineered to excel in voyages of up to 20 days or 2,500 nautical miles (nm). However, the new XLR version builds on the hybrid electric technology developed for Oceanus12 and can increase overall mission duration to an incredible 7,500 nm or approximately 60 days with no outside assistance. It is also built for missions in remote areas or regions where access to traditional fueling points is limited, ensuring that operations can continue uninterrupted.

The XLR Oceanus12 has all the power and onboard functionality of the core variant but boasts an increased overall length from 11.55 m to 13 m. While the original Oceanus12 has a fuel capacity of 1,200 liters and approximately 2,500 nautical mile range or a 20- to 25-day mission, the XLR can carry 4,000 liters of fuel and travel more than 7500 nautical miles, the equivalent of 60+ day missions.

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