In July 2026, the Royal Navy increased its monitoring of Russian vessels by 25%, spending 21 days shadowing ships like the Admiral Grigorovich. This surge responds to Moscow's 'shadow fleet' evading sanctions to fund the war in Ukraine, prompting heightened patrols in the Dover Strait and North Sea.

Royal Navy Steps Up Vigilance

The Royal Navy has reported a significant increase in Russian naval activity near UK waters. During July 2026, surveillance operations rose by 25% compared to the previous year, with 21 days dedicated to constant monitoring of Moscow's vessels in the Dover Strait and the North Sea.

To counter this, the UK deployed patrol boats such as HMS Tyne, HMS Mersey, and HMS Severn, supported by Wildcat helicopters from 815 Naval Air Squadron and Merlin submarine-hunting aircraft. The Russian ships under surveillance included the frigates Neustrashimy and Admiral Grigorovich.

What is the 'Shadow Fleet'?

The term 'shadow fleet' refers to a group of aging tanker ships that Vladimir Putin uses to evade international sanctions on Russian oil. The main goal is to continue exporting crude and thus finance the invasion of Ukraine. In June 2026, British Royal Marines intercepted the vessel Smyrtos, marking the first time UK troops directly boarded a ship from this fleet.

NATO and the North Atlantic

The British effort extends beyond its immediate waters. The frigate HMS Somerset participated in a four-month deployment in the North Atlantic under NATO command, focusing on submarine hunting. Commander Matt Millyard expressed pride in the mission, stating it demonstrates the Royal Navy's work: 'protecting the UK and our allies wherever our interests are threatened'.

Key Data and Figures

  • The UK Ministry of Defence (MoD) reported that in the year up to March 2026, Royal Navy ships were activated 116 times to monitor 61 Russian warships and 28 merchant vessels.
  • This reflects a 30% increase in Russian naval activity over the past two years.
  • The spy ship Yantar, spotted near undersea cables off Scotland in November 2025, was also subject to deterrence operations.
  • The UK has sanctioned more than 500 ships. As a result, Russia's oil and gas revenues fell by 24% year-on-year in 2025.
  • On July 20, 2026, HMS Tyne monitored the Neustrashimy during a live-fire exercise outside British and French waters.
