Diesel outboards powering autonomous marine operations
Safe, fuel-efficient propulsion for next-generation uncrewed surface vessels
Supporting autonomous marine operations
Uncrewed surface vessels (USVs) are reshaping maritime defence, surveillance and research across the US – demanding propulsion systems that combine power, range and low-maintenance reliability. Cox Marine diesel outboards are increasingly chosen as the preferred solution for USV platforms operating in complex, high-risk environments.
The V8 diesel outboard’s single-fuel simplicity and robust engineering empower US operators to deploy USVs that can remain at sea for extended periods, ensuring continuous, high-performance operation without human intervention.
Why Cox Marine 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 customize
Open controls architecture
Cox Marine’s open control architecture gives USV developers the freedom to customize – 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.
Key features – built for uncrewed marine platforms
Power and precision
Delivering high torque at low RPM, the twin-turbo V8 ensures stable, precise propulsion and maneuverability, key attributes for USVs tasked with surveillance, interdiction, or research.
Easy integration
Featuring a universal transom mounting pattern and compatibility with industry-standard control systems, the V8 adapts easily into USV designs – whether for new builds or retrofit solutions.
Environmentally responsible
Certified to meet EPA, IMO II and RCD II standards, the V8 supports US operations with superior emissions performance and efficiency, ensuring that your autonomous platforms stay ahead of both operational and environmental challenges.
