Diesel outboards powering uncrewed marine operations
Safe, fuel-efficient propulsion for next-generation uncrewed surface vessels.
Supporting uncrewed marine operations
Uncrewed surface vessels (USVs) are remotely operated or autonomous craft that carry out maritime defence, surveillance and research tasks without a crew onboard. Demanding propulsion systems that offer power, range and minimal maintenance, Cox Marine diesel outboards are increasingly selected for USV platforms operating in challenging, high-risk environments worldwide.
Our V8 diesel outboards deliver the extended endurance, spark-free safety and rugged engineering required for long-duration autonomous missions. From polar monitoring to ecological surveys, Cox Marine is powering the future of uncrewed maritime capability.
Why Cox diesel outboards are ideal for USVs
Remove time consuming repairs
Hot-swap capability
Diesel outboards with “hot-swap” capability eliminate the need for time-consuming inboard repairs – rapid replacement gets vessels back on mission fast, delivering vital tactical and logistical advantages for decisive naval operations.
Greater safety, lower volatility
Single fuel
In single-fuel operations, diesel outboards align with naval logistics – using the same fuel as larger vessels to boost interoperability, extend range, and enhance endurance, all with greater safety and lower volatility than gasoline.
Freedom to customise
Open controls architecture
Cox Marine’s open control architecture gives USV developers the freedom to customise – broadcasting data via standard ISO CANbus for seamless integration, and offering full access to control protocols and error-handling software for tailored autonomy and system compatibility.
Performance Data
Key features – built for uncrewed marine platforms
Power and precision
High torque at low revs ensures smooth propulsion and directional stability – essential for mission accuracy and safe automated navigation.
Easy to integrate
Compatible with industry-standard control systems and offering flexible mounting and steering options, the V8 is perfect for new USV designs or hybrid propulsion strategies.
Environmentally compliant
Certified to IMO II, RCD II, BSO-II, and EPA Tier 3 standards, the V8 meets stringent environmental requirements, supporting defence, security and research applications with minimal emissions impact.
Trusted by USV innovators
From pilot projects to research collaborations, Cox Marine works with leading USV developers to deliver safe, long-range propulsion for uncrewed fleets. Backed by a support network and expert technical partners, we are at the forefront of autonomous maritime capability.
