UK Armed Forces Weekly News Roundup

6th of June to the 12th of June 2026

Today, 12.06.2026, The newly appointed Secretary of State for Defence, Dan Jarvis MBE MP (centre) arrived this morning at MOD Head Office in London.

This UK Armed Forces weekly news roundup covers key defence developments between the 6th of June and the 12th of June 2026. The week included the conclusion of NATO anti-submarine warfare training in the Norwegian Sea, F-35B Lightning jets returning to HMS Prince of Wales, 3 Commando Brigade becoming the UK Commando Force, British Army work on land drone swarms, the reformation of 203 Squadron at RAF Lossiemouth and a major change in defence leadership after John Healey and Alistair Carns left government.

Royal Navy Completes Dynamic Mongoose as F-35Bs Return to HMS Prince of Wales

HMS Prince of Wales continued Operation Firecrest in northern waters during the week, operating with HMS Duncan and RFA Tidespring as part of the UK Carrier Strike Group. The task group had been involved in NATO’s Dynamic Mongoose exercise, a major anti-submarine warfare exercise off the coast of Norway.

The exercise brought together submarines, surface ships, helicopters and maritime patrol aircraft from several NATO nations. The UK contribution included Royal Navy warships, RAF P8 Poseidon aircraft, Merlin helicopters, Wildcats and supporting elements working together to detect, track and counter undersea threats.

HMS Prince of Wales operated as the carrier element of the force, while HMS Duncan provided air-defence protection. RAF P8 Poseidon aircraft from CXX Squadron conducted maritime patrol work, including the deployment of sonobuoys. Merlin helicopters and Wildcats supported anti-submarine and force protection activity.

The exercise reinforced the importance of the Norwegian Sea and North Atlantic within NATO defence planning. Submarine activity, undersea infrastructure security and reinforcement routes across the North Atlantic remain central to UK maritime strategy.

F-35B Lightning jets from 809 Naval Air Squadron returned to the deck of HMS Prince of Wales during the week as the Carrier Strike Group continued its northern deployment. Their return strengthened the carrier’s strike element and linked the exercise activity to wider UK carrier aviation regeneration.

HMS Prince of Wales also entered Stavanger after the exercise, where a minor technical issue was identified while the ship was alongside. The issue was not presented as a major disruption, and the carrier was expected to return to sea within days.

HMS Duncan later accompanied the Danish frigate Esbern Snare towards Aarhus after Dynamic Mongoose, with sailors from both ships taking part in personnel exchanges during the passage from northern waters towards the Baltic.

Royal Marines Become the UK Commando Force After Royal Approval

On the 10th of June, 3 Commando Brigade was officially renamed the UK Commando Force. The change was confirmed as the King presented new Colours to 40 Commando, 42 Commando, 43 Commando and 45 Commando at Windsor Castle.

The new title reflects the modern structure of the formation, which now brings together Royal Marines, Army Commandos and Royal Navy Commandos under a single operational identity. It also marks the continued shift towards the Future Commando Force model, which has been reshaping the Corps since 2017.

The UK Commando Force is being developed for dispersed operations, greater reach, longer endurance and closer integration with crewed and uncrewed systems. The force is expected to operate in smaller teams, often from the sea, using drones, surveillance systems, digital communications, specialist vehicles and modern weapons to support littoral strike and rapid-response tasks.

The renaming reflects a move away from a traditional brigade identity towards a force structured for contemporary maritime operations. The timing also links closely with Royal Navy activity in the High North, where carrier strike, commando operations and allied deterrence are increasingly connected.

British Army Advances Land Drone Swarm Work and Trains Across Northern Europe

New Colours for the Grenadier Guards, just in time for Trooping the Colour! On Tuesday 9th June 2026

The British Army completed the first phase of research and development into land drone swarms during the week. The work forms part of the Army’s wider effort to develop a more mobile and technologically enabled land force.

The first phase focused on a software-defined swarm test bed, which has now been fielded for further experimentation. The programme is intended to support future uncrewed ground systems that can operate together, share information and carry out battlefield tasks including reconnaissance, resupply, casualty evacuation and movement across exposed routes.

The work reflects the growing importance of uncrewed systems in land warfare. Recent conflicts have shown that drones and autonomous platforms can alter how forces move, observe and survive on the battlefield. The Army’s next challenge is to move from experimentation to equipment that can be used reliably by soldiers under operational conditions.

British troops were also active in northern Europe during the week. Personnel from 3rd Battalion, The Rifles trained in Finland during Exercise Northern Star, using a one-way effector uncrewed aircraft system called Bolt. B Company, 3rd Battalion, The Parachute Regiment carried out cold load training with a US Army CH-47 Chinook at Vuosanka Training Area.

In Estonia, British personnel from 4 Brigade continued NATO-linked training, with activity designed to improve battlefield readiness alongside allied forces. Personnel from 1st Military Working Dog Regiment were also operating during Exercise Spring Storm, adding search and force protection capability to the wider training environment.

Royal Air Force Supports Submarine Hunting and Reforms 203 Squadron

The first Wedgetail Airborne Early Warning (AEW) aircraft, destined to serve with the RAF arrived at RAF Lossiemouth

On the 11th of June, 203 Squadron was reformed at RAF Lossiemouth to support the RAF’s P8 Poseidon maritime patrol aircraft and Wedgetail airborne early warning aircraft.

The squadron replaces the previous Poseidon Line Squadron role and will provide engineering support for two of the RAF’s most important surveillance platforms. Poseidon is central to submarine hunting and maritime patrol, while Wedgetail will restore the UK’s fixed-wing airborne early warning and control capability.

RAF Lossiemouth is now one of the most important air bases in the UK defence system. It hosts Poseidon, Typhoon and Wedgetail activity, giving it a central role in monitoring the North Atlantic and High North. Engineering support is critical because aircraft availability determines how effectively the UK can sustain surveillance and patrol operations.

RAF P8 Poseidon aircraft from CXX Squadron also supported Dynamic Mongoose, flying maritime patrol missions and deploying sonobuoys during NATO’s anti-submarine warfare exercise off Norway.

RAF Typhoons from 3 Fighter Squadron remained active on Operation Biloxi in Romania, where they continued NATO air policing from Borcea 86th Air Base. The mission supports alliance air defence on NATO’s eastern flank and remains one of the RAF’s most visible current operational commitments in Europe.

Defence Leadership Changes After Healey and Carns Leave Government

The main political development of the week came on the 11th of June, when John Healey left his role as Defence Secretary and Alistair Carns DSO OBE MC MP also left government.

The departures followed disagreement over the Defence Investment Plan and the level of funding needed to meet the demands placed on the Armed Forces. The issue moved beyond routine political management because it involved the future funding of programmes linked to readiness, munitions, air defence, housing, drones, maritime security and force structure.

Healey’s departure was significant because he had been closely associated with the Strategic Defence Review and the government’s defence policy direction. Carns leaving government added further pressure, as he had served as Minister for Veterans and People and had also been closely involved in the Armed Forces brief.

Dan Jarvis MBE MP was appointed Secretary of State for Defence on the same day. A former Army officer and former Security Minister, Jarvis takes over the Ministry of Defence at a difficult point. The Strategic Defence Review has set out the broad direction of travel, but the Defence Investment Plan will decide which ambitions are funded, delayed or reduced.

His immediate task will be to stabilise the department and give the services clarity. Carrier strike, anti-submarine warfare, land drones, air defence, munitions, service accommodation and personnel support all sit within the same funding argument.

The change also matters for the wider Armed Forces community. Service personnel, veterans, families, industry and allies will all be watching whether the new Defence Secretary can turn defence policy into deliverable programmes.

Veterans, Housing and the Service Community

On the 9th of June, the Ministry of Defence appointed Natalie Elphicke Ross OBE as interim chair of the new Defence Housing Service. The service is due to manage almost 50,000 military homes across the UK and is being established to deliver the Defence Housing Strategy.

Military housing remains one of the most practical welfare issues facing serving personnel and their families. Poor accommodation, slow repairs and inconsistent standards have all been recurring concerns across the Armed Forces community. The appointment of an interim chair marks a step towards a more formal housing structure, but delivery will be judged by whether families see clear improvements.

The MOD also released survey data showing improved satisfaction with military homes and repairs. Overall satisfaction with military housing rose to 75 percent, while satisfaction with repair services also improved.

Even with those figures, housing will remain closely watched because it directly affects morale, retention and family stability. It is also one of the areas that will sit under the wider funding pressure facing the new Defence Secretary.

Strategic Overview: North Atlantic Security and Defence Funding Dominate the Week

Having given a Royal Salute, the Parade give three cheers for His Majesty the King. New Colours for the Grenadier Guards, just in time for Trooping the Colour!

Between the 6th of June and the 12th of June 2026, UK defence activity centred on the North Atlantic, northern Europe and the future funding of the Armed Forces.

The Royal Navy and RAF completed Dynamic Mongoose with NATO partners, while HMS Prince of Wales continued Operation Firecrest with F-35Bs embarked. The Royal Marines formally adopted the UK Commando Force name. The British Army moved further into land drone swarm experimentation, and the RAF strengthened engineering support for Poseidon and Wedgetail at Lossiemouth.

The week ended with a major political change at the Ministry of Defence. John Healey and Alistair Carns leaving government, followed by Dan Jarvis becoming Defence Secretary, placed the Defence Investment Plan at the centre of the defence debate.

The plan will decide how far the ambitions of the Strategic Defence Review can be turned into funded capability. It will also shape decisions on equipment, personnel, housing, readiness and the industrial base.

Capability Watch

The British Army’s land drone swarm project was the clearest emerging capability story of the week. Completion of phase one gives the Army a software-defined testbed for further experimentation with uncrewed ground systems.

The reformation of 203 Squadron at RAF Lossiemouth was the main air support development. The unit will provide engineering support to P8 Poseidon and Wedgetail aircraft, both of which are central to the UK’s northern surveillance, anti-submarine and airborne warning capabilities.

The change in defence leadership also becomes part of the capability picture. The new Defence Secretary will inherit major decisions on the Defence Investment Plan, including how far future programmes can be funded and at what pace.

Looking Ahead

The next week will show whether HMS Prince of Wales returns quickly to the full Carrier Strike Group programme after the issue identified in Stavanger. Attention will also remain on the Ministry of Defence after the departure of John Healey and Alistair Carns and the appointment of Dan Jarvis as Defence Secretary.

Dynamic Mongoose has concluded, but the operational themes remain active. Submarine monitoring, northern deterrence, carrier strike, maritime patrol aircraft and NATO integration will continue to shape UK defence activity in the coming weeks.

The Defence Investment Plan will now be watched closely by serving personnel, veterans, industry and allies. It will decide whether recent announcements on drones, air defence, housing, munitions and readiness are matched by the funding needed to deliver them.
