The Royal Navy has completed an intensive three-day operation tracking Russian warships and sanctioned cargo vessels through waters around the UK, as new figures show British naval activations to monitor Russian activity have risen by 25% compared with last year.
HMS Duncan, HMS St Albans and HMS Severn used their sensors and radars to monitor two Russian Navy warships and two sanctioned cargo ships as they travelled through the North Sea and English Channel.
A Merlin helicopter launched from HMS St Albans also joined the operation as the vessels approached the Strait of Dover, extending the Royal Navy's surveillance from the air.
Russian task group tracked through Channel
According to the Royal Navy, Type 45 destroyer HMS Duncan, Type 23 frigate HMS St Albans and patrol ship HMS Severn tracked Russian destroyer Admiral Levchenko as it escorted the sanctioned cargo vessels General Skobelev and Sparta south through the North Sea and into the English Channel.
Russia also deployed the frigate Neustrashimy during the passage. The British ships followed the group through the Channel before handing monitoring responsibility to a NATO ally off the French coast near Ushant.
At the same time, HMS Mersey was monitoring the Russian replenishment vessel Akademik Pashin nearby.
Monitoring activations rise 25%
The Royal Navy says activations to monitor Russian activity increased by 25% during the first eight months of 2026 compared with the same period in 2025.
Earlier in August, the Ministry of Defence reported the same 25% year-on-year increase across the first seven months of 2026, after Royal Navy ships and helicopters spent 21 days monitoring Russian activity during July alone.
HMS Severn deployed three times in August
The Royal Navy says HMS Severn has now been dispatched three times during August to report on Russian movements.
Earlier in the month it tracked Neustrashimy through the Channel before later operating alongside HMS Tyne to monitor Admiral Gorshkov, hydrographic vessel Romuald Muklevich and Akademik Pashin.
Royal Navy links activity to shadow fleet crackdown
The Royal Navy has linked the increased monitoring to Britain's wider campaign against Russia's shadow fleet — vessels Western governments say are used to circumvent sanctions and sustain revenues supporting Moscow's war in Ukraine.
The UK says it has sanctioned more than 500 vessels. The latest operation follows Britain's interdiction of the sanctioned shadow-fleet tanker Smyrtos in the English Channel in June.
First Sea Lord General Sir Gwyn Jenkins said that since the Smyrtos operation, Russian shadow-fleet vessels had increasingly been forced to change routes, imposing additional costs and delays. He also argued that Moscow was being forced to divert warships from other duties to protect vessels moving around Europe.
Those conclusions are the Royal Navy's assessment and should not be treated as independently established measurements of the effect on Russian naval operations.
Navy describes cargo as an ‘illegal shipment’
The Royal Navy said Russia had been forced to deploy military resources, including Neustrashimy, to guard what it described as an “illegal shipment”.
The Navy identifies General Skobelev and Sparta as sanctioned cargo vessels but its announcement does not establish the precise contents of the cargo. The description of the shipment as illegal is therefore the Royal Navy's characterisation.
St Albans commander says operations will continue
Commander Oli Ayers, commanding officer of HMS St Albans, said the frigate had operated alongside NATO warships and aircraft to escort and monitor the Russian military and merchant vessels.
He described such operations as core business for the Navy's high-readiness frigate and said similar missions alongside NATO allies would continue over the coming months.
July saw 21 days of Russian monitoring operations
In figures published on 8 August, the Ministry of Defence said Royal Navy warships and helicopters spent 21 days during July monitoring Russian activity in UK waters and the North Atlantic.
HMS Somerset, HMS Tyne, HMS Mersey and HMS Severn were involved alongside Wildcat and Merlin helicopters.
During one operation on 20 July, HMS Tyne monitored Neustrashimy conducting gunnery firings outside UK and French territorial waters, moving to within five nautical miles while gathering intelligence.
Operational pressure comes amid defence spending debate
Although monitoring Russian vessels passing through areas of UK interest is a routine Royal Navy responsibility, the 25% year-on-year increase demonstrates that the frequency with which British assets are being activated for the task has grown.
The latest operation also illustrates the range of assets involved: destroyers, frigates, patrol vessels and naval helicopters were all used during the three-day mission.
For ministers, the figures provide a concrete example of the operational demands being placed on the Armed Forces as the Government considers its longer-term defence spending commitments.
Royal Navy promises continued vigilance
Jenkins said there was no room for complacency and argued that shadow-fleet vessels continued to pose risks to maritime security and the environment.
He said Britain would continue working with allies to uphold and enforce international law.
With activations now running 25% above last year's level, the figures show that what the Navy describes as routine monitoring is requiring an increasing tempo of British maritime activity.
