Diesel outboards powering military and defence operations
Safer, more efficient propulsion for tactical marine missions.
Supporting defense operations where performance is non-negotiable
In today’s high-stakes security environment, US military and defense agencies demand propulsion systems that offer robust power, extended range, and uncompromised safety. Cox Marine diesel outboards are ideal for applications ranging from Navy support craft and coastal patrol boats to special operations vessels and USVs.
Our V8 diesel outboard delivers the performance, durability, and spark-free operation required for aggressive tactical missions and border interdiction. With the single fuel advantage, US forces benefit from enhanced operational simplicity and extended mission endurance.
Why Cox Marine diesel outboards are ideal for military and defense applications
Reducing risk
Spark-free operation
Unlike gasoline engines, Cox Marine diesel outboards use compression ignition, significantly reducing the risk of explosion when operating in high-threat or flammable environments – critical for covert missions and front-line defense.
Increased fuel efficiency
Extended mission range
Offering increased fuel efficiency over gasoline engines, Cox Marine outboards provide US military vessels with the endurance to stay deployed longer without the need for mid-mission refueling, a tactical advantage on extended patrols.
Minimized maintenance
Built for uptime
With longer service intervals and rugged engineering, the V8 is designed to minimize maintenance demands and ensure mission readiness. For defense fleets, this means less downtime and more operational days at sea.
Key features – built for military readiness
Maximum torque for maximum control
The twin-turbo V8 delivers high torque at low RPM, providing smooth and precise control necessary for rapid maneuvers during tactical operations.
Flexible integration
With a universal transom mounting pattern and compatibility with a variety of US-standard control systems, Cox Marine outboards can be seamlessly integrated into new builds or repower projects across various defense platforms.
Rugged and compliant
Certified to meet EPA regulations as well as IMO II and RCD II standards, the V8 ensures that US military operations can meet both performance and environmental requirements without compromise.
