Royal Navy Tracks Russian Shadow Fleet Frigate for 30 Days
The Royal Navy tracked a Russian frigate every day for one month last month as it sailed from the Atlantic to the North Sea, in a case tied to the russian shadow fleet. Four UK ships and helicopters watched Admiral Grigorovich continuously during April as the Russian navy vessel escorted six Russia-linked vessels near Britain.

Admiral Grigorovich escorted at least three vessels that were under economic sanction and passed east through the Dover strait. Naval spotters believe Admiral Grigorovich remains in the North Sea, and the frigate took on supplies near Galloper windfarm off the Suffolk coast.
That movement put a British watch force on repeated patrols for 30 days. Britain’s Royal Navy was not tracking a single isolated transit; it was shadowing an escort operation that kept Russia-linked shipping close to UK waters through the month.
Keir Starmer and UK Waters
On 25 March, Keir Starmer said the military was able to seize ships subject to existing economic sanctions that were transiting through UK waters. Starmer said the UK would be going after Vladimir Putin’s shadow fleet even harder, while Elisabeth Braw said, “This is completely disproportionate; navies normally only escort vessels when there is a clear military threat, such as from the Houthis in the Red Sea.”
Braw also said, “Russia has decided that this is an indispensable source of income that could be disrupted. Clearly, if the Russians thought these vessels were not going to encounter problems, they would not allocate a frigate.” The escort pattern left the Royal Navy facing a moving target: Russia used two frigates in April, and Britain had to keep watch as the second, Admiral Kasatonov, passed through the Channel towards the end of April.

Admiral Kasatonov escorted two merchant ships believed to be heading towards Tartus in Syria, including the Sparta, which is associated with the transport of arms. A British auxiliary ship, the RFA Tideforce, monitored that convoy, adding another layer to the British response at sea.
The wider friction point is that Russia is relying on escorts to move vessels that Britain and other European countries want to stop. Sweden has detained five tankers this year, France has seized two Russia-linked tankers with UK assistance this year, and each of those French seizures ended only after owners paid a fine.
For Britain, the next practical test is whether the UK turns its 25 March warning into action while Russian escorts remain present near the Dover strait and the North Sea. Braw put the risk plainly: “The Russian government has shown it is willing to use its naval power to protect vessels that break maritime rules. It makes it much more difficult for coastal states to intervene. You have to be willing to risk a confrontation with the escort.”
