ZeroUSV has unveiled the first of its new Oceanus17 class of USV, named The Lady of the Lake and representing the next generation of UK maritime innovation. Her name is intended to reflect her advanced capabilities for resilient, enduring, and multi-tasking operations across extended maritime missions.
Officially named at a ceremony held during Plymouth’s British National Firework Championships, by Rebecca Smith MP, the naming draws on the Arthurian tradition, following the maritime autonomy heritage established by MSubs' recent delivery of HMS Excalibur to the Royal Navy.
"Today is a celebration of ZeroUSV, demonstrating to the wider world what delivering cutting edge British technology and innovation at pace really means."
" Just over one year ago we launched the first of our Oceanus12 USV’s, and today, with the first Oceanus17 USV officially named, we've demonstrated our ability to design, build, and deliver successive generations of world-class autonomous vessels in just over six months.
The Oceanus17 class represent a significant step up in British autonomous USV capability - with very large payload capacity of 4,000kg, mission endurance in excess of 50 days, a top speed
approaching 15 knots, whilst still retaining the Oceanus class DNA allowing fast mobilisation to any corner of the globe quickly and easily.
Delivering the Oceanus17 proves ZeroUSV’s commitment to British maritime innovation, further enhancing the UK’s sovereign capability to produce advanced USVs, and continues to strengthen Plymouth’s position and reputation as both a National and International centre for maritime autonomy.”
- Matthew Ratsey, Managing Director ZeroUSV

UK built and based
Built at Manor Marine's shipyard in Portland and launched from Turnchapel Wharf Plymouth, Oceanus17 represents the next evolution in ZeroUSV's proven Oceanus class family.
The vessel builds on the engineering success of the Oceanus12, providing extended endurance of over 50 days per mission, and a 20-foot ISO-compatible payload bay with 30 kw of dedicated payload power.
"The Oceanus 17, the Lady of the Lake, is a remarkable achievement by British innovators. Her ability to operate independently, endure extended missions, and perform multiple roles across the maritime domains embody the qualities we need in our defence, and commercial maritime capabilities."
“ZeroUSV's progress in delivering world-class autonomous vessels demonstrates the potential of the UK's marine autonomy sector in Plymouth, and why we must continue to champion, cut unnecessary
red tape and invest in this critical technology."
- Rebecca Smith MP

Next steps for ZeroUSV
The fully autonomous vessel incorporates level-four autonomous navigation, delivered by MarineAI's GuardianAI autonomy stack, while dual-redundant engineering systems eliminate single
points of failure.
This provides the Oceanus17 with the resilience necessary for persistent, over-the-horizon operations in the most challenging of maritime environments.
There is no standing still, as in the next week this first of class Oceanus17 will be mobilised for deployment to Portugal, representing Britian and the Royal Navy for NATO Exercise REPMUS for the entire month of September.
