Inside the Royal Navy’s new mine warfare mothership programme

Navy Lookout – The RN’s autonomus mine hunting systems will be deployed on board up to three new Offshore Support Vessels (OSV) or ‘motherships’ procured in partnership with Norway. Recent work by Dstl and NDP provides the clearest indication yet of what the ships may need to look like, suggesting something much closer to a large commercial offshore vessel than a conventional naval auxiliary. Here we look at what is known about this programme.

Should the Royal Navy establish a coastal drone flotilla to monitor Russian warships?

Navy Lookout – With an increasing number of Russian warships operating close to the UK, the overstretched Royal Navy is being forced to employ lightly-armed OPVs, RFAs and minehunters to monitor them. This sends a message of weakness. This editorial argues that also deploying multiple small, fast uncrewed surface vessels offers a rapid and affordable means to provide more effective deterrence.

Royal Navy carrier strike group spearheads NATO Arctic deterrence mission

Navy Lookout – The UK Carrier Strike Group led by HMS Prince of Wales, has taken command of a major NATO maritime activity in the High North. Exercise Neptune Strike 26-3 marks the first time the Alliance’s recurring enhanced Vigilance Activity has expanded into the Arctic and North Atlantic, reflecting NATO’s growing focus on deterring Russian activity in one of its most strategically important regions.

Sea Breeze 2026: the Royal Navy hosts Ukraine and allies to build mine warfare expertise

Navy Lookout – Exercise Sea Breeze, the annual US-Ukraine-led maritime exercise, has returned to Portland for its 2026 mine countermeasures phase. This is the largest UK-hosted iteration to date and is building Ukrainian capability while sharpening the mine warfare skills of allied navies at a time when the discipline has regained wider strategic urgency.

Operation Firecrest: HMS Prince of Wales Demonstrates Royal Navy’s ‘Hybrid’ Shift

Naval News – The current deployment of the UK Royal Navy’s (RN’s) HMS Prince of Wales carrier strike group (CSG) across the North Atlantic and into the High North is building deterrence against regional threats – but is also demonstrating the navy’s quickening transition towards a ‘hybrid’ crewed/uncrewed operational force structure.

XV Excalibur – Royal Navy learning to fight with autonomous submarines

Navy Lookout – The RN’s experimental extra-large uncrewed underwater vehicle, XV Excalibur, has entered a new phase of development. MSubs of Plymouth was recently awarded a £6.68 million contract to support the RN trials. We spoke with the company about the programme as the RN moves from learning how to operate XLUUVs to deploying functional payloads.

Pioneer USV validates long-endurance maritime surveillance concept

Royal Navy – ACUA Ocean has completed a five-day offshore demonstration of its Pioneer uncrewed surface vessel (USV), showcasing its ability to carry out persistent surveillance and hydrographic survey tasks simultaneously without requiring physical intervention. The trial highlights the growing potential of autonomous vessels to support future Royal Navy and maritime security operations.
