Royal Navy tracks Russian frigate Admiral Grigorovich near UK waters after shadow-fleet escort activity.
Britain’s Royal Navy tracked the Russian frigate Admiral Grigorovich every day for about a month as it sailed from the Atlantic into the North Sea and supported Russia-linked maritime movements near the United Kingdom. The Guardian reported that the frigate escorted six Russia-linked vessels during April, including at least three vessels under economic sanctions passing east through the Dover Strait. The ship was monitored continuously by four UK ships and helicopters, indicating that London treated the movement as a significant maritime security event rather than ordinary naval passage. The frigate reportedly maintained its presence near Britain by taking on supplies near the Galloper wind farm off the Suffolk coast. This proximity to UK waters and maritime infrastructure gives the incident hybrid relevance, especially because it occurred after the UK announced authority to seize sanctioned Russian shadow-fleet tankers. A second Russian frigate, Admiral Kasatonov, also passed through the Channel later in April escorting two merchant vessels, one reportedly associated with arms transport. The case shows how Russia may use naval escorts to deter European enforcement actions against its sanctions-evasion fleet. It does not represent sabotage, because no damage to infrastructure was reported, but it does represent a form of coercive maritime signalling. The key point is that Russia is increasingly protecting grey-zone commercial shipping with overt naval power, complicating NATO and UK maritime enforcement options.
