Russian Frigate Fires Warning Shots Near a British Yacht off the Isle of Wight
Portsmouth, 16 June 2026
Key points
- The Russian frigate Admiral Grigorovich fired warning shots, including small-arms fire, to divert a British-flagged civilian yacht about 20 nautical miles south of the Isle of Wight on 16 June, in fog and outside UK territorial waters
- A Royal Navy patrol vessel, HMS Mersey, was shadowing the frigate; the UK said the shots were not aimed at the yacht and were meant to prevent a collision
- Accounts of the separation differ — UK authorities put it at about 500 yards, Russia at around 150 metres
- The UK does not link the incident to the Royal Marines' boarding of the sanctioned tanker Smyrtos two days earlier
The Russian frigate Admiral Grigorovich fired warning shots to divert a British-flagged yacht about 20 nautical miles south of the Isle of Wight on 16 June — in fog, outside UK waters, shadowed by a Royal Navy patrol ship — in an incident London and Moscow describe very differently.
The frigate fired small-arms warning shots across the yacht's course; no one was hurt. The UK Ministry of Defence said the shots were not aimed at the vessel and were an attempt to prevent a collision, suggesting the yacht may have drifted toward the warship, which was signalling that it was not under power. Russia said the yacht was on a collision course and turned away only after radio contact failed. The accounts of distance diverge by side — UK authorities put the separation at about 500 yards, Russia at around 150 metres — and the Royal Navy patrol vessel HMS Mersey was monitoring the frigate throughout.
London does not link the episode to the Royal Marines' boarding of the sanctioned shadow-fleet tanker Smyrtos two days earlier, though the same frigate had spent weeks in the Channel and in April escorted Russian oil tankers through it.
The proprietary read. The significance is the normalisation of an armed Russian naval presence in the Channel, not the contested yards. A Russian frigate escorting sanctioned tankers and firing warning shots at a civilian boat in Britain's approaches is the maritime face of the same confrontation playing out in the shadow-fleet boardings — Moscow asserting a right to operate, armed, in waters Europe is trying to police. The yacht incident will be argued as an accident; the standing fact beneath it is that the Channel is now contested water, with a Russian warship in it. Tracked in Signal No. 83.
