The English Channel, one of the world’s busiest shipping lanes and a vital artery for international trade, recently became the stage for a tense maritime encounter. In a clear demonstration of vigilance and capability, the Royal Navy shadowed a Russian submarine, the Kilo-class Krasnodar, as it navigated through UK waters. This proactive operation underscores Britain’s unwavering commitment to safeguarding its national interests amidst escalating Russian naval activity in UK waters.
The incident unfolded as the Krasnodar, accompanied by its tugboat Altay, transited on the surface from the North Sea, through the narrow Strait of Dover, and into the Krasnodar submarine English Channel. The task of tracking these Russian vessels fell to the Royal Fleet Auxiliary (RFA) tanker Tidesurge. Equipped with a specialist Merlin helicopter – a formidable asset for anti-submarine warfare – the Tidesurge maintained a close watch. Captain James Allen, commanding officer of RFA Tidesurge, emphasized the vessel’s role in providing “a show of presence and deterrence.” The Royal Navy confirmed its readiness to “pivot to anti-submarine operations” if the Krasnodar had submerged, highlighting the sophisticated capabilities brought to bear in such sensitive situations. The operation, spanning three days, culminated near the north-west of France, where tracking responsibilities were seamlessly handed over to a NATO tracks Russian sub ally, showcasing robust international cooperation.
This latest development is not an isolated event but part of a discernible pattern. The UK government has reported a significant 30% increase in Russian vessels posing potential threats to British waters over the past two years. While Russia characterises these instances as routine movements and accuses the UK of provocation, the perceived increase in assertive Russian behaviour necessitates heightened defensive postures. The broader strategic implications extend beyond surface incursions. Defence Secretary John Healey recently launched the Atlantic Bastion programme, a critical initiative aimed at fortifying the UK’s crucial undersea cables and pipelines against potential Russian threats undersea cables. This programme follows a concerning revelation just a month prior, where a Russian spy ship was accused of using lasers against RAF pilots monitoring its activities near UK shores, reportedly for intelligence gathering and mapping critical infrastructure.

In a stark message directed at Russian President Vladimir Putin, Healey declared, “We see you. We know what you are doing. And we are ready.” This firm stance encapsulates the UK’s resolve in protecting its sovereignty and infrastructure. The Russian embassy, however, has dismissed claims of interest in British underwater communications, urging the UK to avoid “destructive steps” that could escalate tensions.
The multi-faceted nature of these contemporary threats is also evident in the digital realm. House Commons Speaker Sir Lindsay Hoyle has alerted MPs to a rise in Russian-linked phishing attempts targeting their commercial messaging apps like Signal and WhatsApp. This underscores a broader hybrid warfare strategy, where cyber intrusions complement conventional military posturing.
In an increasingly complex geopolitical landscape, the Royal Navy’s unwavering vigilance, exemplified by the tracking of the Krasnodar, is paramount. Such operations serve as a vital deterrent, reinforcing UK national security maritime and ensuring the integrity of its waters. The collaborative efforts with NATO allies further strengthen this protective shield, sending a clear message that the UK and its partners remain on alert, ready to respond to threats across all domains.
