Sea trials of Sea Archer – the first Australian-built uncrewed surface vessel (USV) – mark an important milestone in the evolution of autonomous maritime systems.

Developed by Leidos Australia the platform demonstrates what can be achieved through innovation, collaboration and advanced autonomous marine propulsion. Cox Marine propulsion plays a key role, with twin 300 V8 diesel outboards delivering the reliability, efficiency and endurance required for mission-critical operations, supplied by Power Equipment Pty Ltd.

With a range of up to 1,500 nautical miles, Sea Archer has been engineered for persistence and adaptability, supporting operations from surveillance and logistics resupply to more complex and evolving mission profiles.

The project also highlights the importance of strong regional partnerships, combining global engineering expertise with local knowledge to deliver robust, supportable solutions fit for purpose.

Meet James Eatwell, Chief Technical Officer at Cox Marine.

James has been part of the Cox Marine journey for over a decade, turning a lifelong passion for engines into industry-leading innovation. Drawn by the opportunity to work on something truly different, James recognised early on that Cox Marine wasn’t just building another engine, instead pioneering a completely new approach from a clean sheet.

Hugh Hudleston is at ⚓🇫🇷 NAVEXPO 2026, supporting valued distributor partner LB Tender Mechanics. Some great discussions taking place on diesel outboard innovation. Built for demanding maritime operations, Cox Marine’s propulsion alternative delivers the reliability, fuel efficiency and durability trusted by defence and commercial operators worldwide.

As defence, government, and commercial operators accelerate their adoption of USVs, one factor has quickly become clear, and that is propulsion can no longer be treated as a standalone component.

In modern maritime programmes, particularly those driven by autonomy, success hinges not just on engine performance, but on how seamlessly the propulsion system integrates into the wider platform. Stephen Pitt explains.

Today we recognise U.S. Memorial Day, taking time to remember those who lost their lives while serving in the U.S. armed forces. With long‑standing connections across the United States and active work within the defence sector, this day is an important moment to pause and reflect, alongside our partners, customers and colleagues in the region and around the world.

It was a pleasure to welcome our South Korean distributor, SoungJin Marine, to the Cox Marine facility in Shoreham-by-Sea, UK.

During the visit, Hugh Hudleston heard first-hand feedback from the market, particularly around the performance of our V8 300HP diesel outboards in heavily loaded commercial applications such as seaweed harvesting vessels.

Fuel economy continues to be a standout benefit. While Cox Marine typically cites around 30% fuel efficiency improvements versus petrol outboards, operators in South Korea are seeing up to 50% improvements in real-world conditions.

The reason? Diesel engines working less hard at heavy payloads, delivering the same performance with significantly lower fuel consumption.

It’s great to see the reliability and efficiency of our propulsion alternative delivering tangible value for commercial operators on the water.

Working with Kliqxe, we’ve taken a major step forward in how we manage warranty across Cox Marine, with the go‑live of our new warranty management solution.

For a growing global business like ours, the opportunity was clear - replace slow, manual processes with a system that gives our teams and distributors faster responses, greater transparency and better insight into how our products perform in the field.

Early results are already showing meaningful improvement, cutting response times from days to hours and significantly reducing administrative effort.

Just as importantly, the platform gives us real-time visibility across the entire warranty lifecycle. This means better data, stronger accountability and the ability to make informed decisions that help us continuously improve both product reliability and customer support.

We’re now focused on driving adoption across our global distributor network and ensuring long term value for everyone involved, from our internal teams to operators on the water.
Chris Foxton, Head of Commerical Operations at Cox Marine commented: "We are proud to have delivered a significant advancement in our warranty system, underscoring our commitment to continuous improvement and sustained investment in our growing business.”

We’re proud to be strengthening our long‑standing partnership with Ring Power, extending their Cox Marine distribution territory across the U.S. South.

As Gemma Crocker, Commercial Operations Director at Cox Marine, says:

“Ring Power has consistently demonstrated the highest standards of customer support and operational excellence across its territory. Expanding their reach into these states is a natural next step and ensures our customers benefit from a strong, well-supported distribution network.”

This expansion builds on proven collaboration, enhances regional support, and ensures greater coverage for customers across key southern states, while welcoming Texas Diesel Outboard as an approved dealer within Ring Power’s growing network.
