On the 27th of May, RFA Lyme Bay left Gibraltar configured as a minehunting mothership ahead of possible operations in the Middle East. The Bay-class landing ship sailed with more than 100 mine warfare personnel embarked, drawn from the Royal Navy’s Diving and Threat Exploitation Group and Mine and Threat Exploitation Group. Her tasking is linked to preparations for a potential mission to secure the Strait of Hormuz if conditions allow.

The ship is carrying autonomous minehunting systems intended to reduce the risk to personnel during mine clearance operations. In a confined waterway such as the Strait of Hormuz, uncrewed systems allow mine detection work to be carried out at greater distance from crewed ships.

On the 28th of May, RNMB Ariadne docked inside RFA Lyme Bay in the waters off Gibraltar. The 12-metre uncrewed minehunting craft had previously been carried to Gibraltar by HMS Stirling Castle and was moved into Lyme Bay’s dock as part of operational preparations. The vessel uses a towed sonar system to search for mines and can be controlled locally or from a portable operating centre.

HMS Stirling Castle also completed a separate delivery mission to Gibraltar, carrying specialist minehunting vessels, RHIBs, containers and associated equipment for transfer to RFA Lyme Bay. The ship’s large mission deck and crane enabled the delivery of equipment needed for future mine countermeasure work.

The week also brought a ceremonial first for HMS Stirling Castle, which became the first Royal Navy warship to be formally affiliated with Gibraltar. The affiliation followed the ship’s visit to the Rock and reflects Gibraltar’s continuing role as a forward maritime support location for Royal Navy activity.

In northern waters, HMS Prince of Wales remained involved in NATO anti-submarine warfare activity linked to Exercise Dynamic Mongoose. Imagery released during the week showed a NATO submarine operating with the carrier and a Royal Navy Merlin embarked in HMS Somerset on Operation Ceto, the UK’s standing mission focused on submarine monitoring and the protection of the strategic deterrent in the North Atlantic.

Royal Marines Continue to Feature in Mountain Warfare and Future Littoral Activity

Two Royal Marine mountain leaders were part of the Ranger Regiment team that reached the summit of Mount Everest on the 23rd of May. The expedition involved nine British Army soldiers and two Royal Marines, led by Major Joe Adamson, after more than a year of preparation and medical assessment.

While the Everest expedition was not an operational deployment, it reflected skills relevant to military mountain leadership, endurance and high-altitude movement. Royal Marine mountain leaders remain an important specialist capability within UK defence, particularly for cold weather, mountainous and Arctic operations.

Royal Marines future activity also remained connected to the wider Royal Navy move towards uncrewed and distributed maritime operations. The use of autonomous minehunting vessels around Gibraltar, alongside recent Royal Marines drone and Future Commando Force developments, reflects the continued shift towards smaller teams operating with sensors, uncrewed systems and maritime support.

British Army Ranger Regiment Team Summits Everest

On the 23rd of May, a team from the British Army’s Ranger Regiment reached the summit of Mount Everest. The group was led by Major Joe Adamson and included nine soldiers and two Royal Marine mountain leaders. The expedition raised more than £20,000 for charity and followed more than a year of training, preparation and medical testing.

The expedition required movement through high-altitude terrain, acclimatisation phases and technical mountaineering. The team also operated above 8,000 metres, where oxygen levels are significantly lower and the risk to climbers increases sharply.

Although it was an expedition rather than a combat operation, the achievement sits within the Army’s wider emphasis on resilience, leadership and specialist skills. The Ranger Regiment is designed for persistent engagement and operations with partner forces, and the expedition demonstrated a high level of physical and mental preparation.

The week also included imagery of Allied Rapid Reaction Corps personnel deploying a multinational command post at Charing Cross Underground station in London. The activity tested the ARRC’s ability to operate from an underground location during wartime, reflecting the continued focus on command resilience, dispersal and survivability.

Royal Air Force Reserve Meteorologists Support Operations at RAF Akrotiri

On the 28th of May, RAF Reserve meteorologists completed a deployment to RAF Akrotiri following months of tension in the Middle East. The Mobile Met Unit deployed to Cyprus after the March drone attack on the base and worked alongside civilian Met Office personnel to brief aircrews before sorties across the region.

The Mobile Met Unit is based out of RAF Waddington and draws on Met Office staff serving as RAF reservists. Around 30 meteorologists are part of the unit, providing military forecasting support for operations and exercises.

Weather forecasting is central to fast jet, transport and surveillance operations. At Akrotiri, forecasts support decisions on flying conditions, route planning, fuel use, visibility and the timing of sorties. The deployment added resilience to permanent forecasting support at the base during a period of elevated operational activity.

RAF activity during the week also included continuing Operation Biloxi in Romania, where Typhoons from 3 Squadron remained part of NATO air policing, and ongoing operations from Akrotiri involving Typhoons and other aircraft. Imagery released during the week also showed Russian Su-35 and Su-27 aircraft flying close to an RAF Rivet Joint over the Black Sea, underlining the risk faced by intelligence and surveillance crews operating near contested airspace.

Veterans and Remembrance: HMS Hood and Cavalry Sunday Marked

On the 28th of May, personnel from HMS Collingwood marked the 85th anniversary of the sinking of HMS Hood. The battlecruiser was lost on the 24th of May 1941 during the action against the German battleship Bismarck, with 1,415 of her crew killed. The memorial service recognised one of the Royal Navy’s most significant wartime losses.

The week also included coverage of Cavalry Sunday, with serving and retired personnel taking part in remembrance activity in Hyde Park. The service remains an important annual moment for the cavalry community, linking current serving personnel, veterans and regimental associations.

Veterans and remembrance activity during the week centred less on current policy and more on military memory. Events such as the HMS Hood anniversary and Cavalry Sunday show how service communities continue to maintain links across generations, units and conflicts.

Strategic Overview: Mine Warfare, Submarine Monitoring and Space Communications

Between the 23rd of May and the 29th of May 2026, UK defence activity remained focused on three main areas: maritime security, operational resilience and future communications.

The maritime picture was dominated by mine countermeasure preparations for a possible Strait of Hormuz mission and continuing anti-submarine activity in the North Atlantic. RFA Lyme Bay, HMS Stirling Castle, RNMB Ariadne and associated mine warfare teams showed how the Royal Navy is moving autonomous systems into practical use. HMS Prince of Wales, HMS Somerset and Merlin helicopter activity showed continuing focus on submarine monitoring in northern waters.

On the 27th of May, Dstl confirmed the UK’s first successful optical downlink from space using a deployable laser communications ground station. The demonstration involved downloading data from a low Earth orbit satellite to a ground station in the Mediterranean region during a 90-second pass. The technology is intended to support faster and more secure communications for the UK Armed Forces.

The communications development sits alongside wider efforts to improve resilience in space and contested environments. As military operations rely increasingly on data, sensors and satellite links, secure high-speed communications are becoming a core defence requirement.

RNMB Ariadne’s docking with RFA Lyme Bay was the week’s most significant capability development at sea. It showed how the Royal Navy intends to use uncrewed minehunting craft from a larger mothership during mine countermeasure operations.

Dstl’s optical communications trial was the week’s main technology development. The successful downlink from a low Earth orbit satellite to a deployable laser ground station showed progress in faster, secure data transfer for military use.

Looking Ahead
