Royal Navy intercepts Russian spy ship off Scotland as helicopters track vessel monitoring Nato exercise

Capt James Hall, commanding officer of RNAS Culdrose, said: “I am immensely proud of the efforts of our people, who have once again demonstrated that the UK is prepared to respond to immediate operational requirements.”

He added: “This operation has been a critical means of demonstrating to ourselves, our adversaries and the nation that we are willing and capable of securing the homeland 24/7. The Merlin Helicopter Force stands ready to answer the call at a moment’s notice.”

The Merlin helicopters were redeployed from their home base at RNAS Culdrose in Cornwall to Glasgow Prestwick Airport to carry out the surveillance operation.

The aircraft had earlier this year received a £40million upgrade, fitted with cutting-edge sonobuoys designed to enhance their ability to track Russian submarines.

Exercise Strike Warrior, which the Viktor Leonov had been observing, involved warships from six Nato member states.

The drill saw approximately 2,000 military personnel participate in what represented a significant allied presence in waters around the British Isles.

The interception forms part of a broader pattern of escalating Russian naval activity around Britain, which has risen by 25 per cent in the first seven months of 2026 compared with the same period last year.

Moscow has employed warships, civilian vessels and fishing boats alike.

In the English Channel, HMS Dauntless and HMS Tyne were tasked with shadowing the Russian frigate Neustrashimy from October 1 to 14 as it escorted sanctioned cargo ships.

HMS Tyne subsequently tracked the Aleksandr Shabalin, another Russian vessel escorting cargo, between October 11 and 14.

An unarmed RAF Protector RG1 drone logged more than ten hours of surveillance over foreign ships from late September to mid-October.

Russia has also been using fishing trawlers to gather intelligence on Britain’s critical undersea cable infrastructure.

In June, Royal Marine Commandos seized the Russian shadow-fleet tanker Smyrtos in a six-hour boarding operation ordered by Sir Keir Starmer during his premiership.

In Westminster, a defence spending debate looms large.

On Sunday, Chancellor John Healey declined to make a firm commitment to raising the defence budget to three per cent of GDP by 2030, saying only that Britain would “look to” reach that threshold.

Mr Healey had previously stepped down as defence secretary after Sir Keir Starmer’s Defence Investment Plan fell short of pledging to meet the target.

His reluctance to offer a binding guarantee has raised questions from defence experts on whether the armed forces will receive the resources needed to sustain the tempo of operations now demanded by Russia’s increasingly assertive posture.

The seizure of shadow-fleet tankers, round-the-clock submarine tracking and persistent Channel patrols have all been said to have placed significant strain on a navy that has been described as already stretched by global commitments.

Former generals have told Andy Burnham that Britain is not ready for war and have accused John Healey’s budget of “kicking the can down the road” on defence.

Defence Secretary Wes Streeting has also insisted that the UK must be ready for war within 1,000 days amid an increasing threat from Russia and other hostile powers.
