HMS Brocklesby (M33): From a Burned Ensign Off Cherbourg to Opening Misrata's Port Under Fire

A Minehunter for the Channel Islands and Beyond

HMS Brocklesby, the third Royal Navy vessel to carry the name, was launched on 12 January 1982 and commissioned on 3 February 1983 at HMS Vernon, a Hunt-class mine countermeasures vessel built with a glass-reinforced plastic hull to reduce her magnetic signature.

The name arrives with a good deal of history attached. The Brocklesby before this one was a Hunt-class destroyer, L42, and she had the sort of war that gets books written about it. Commissioned in April 1941 and put straight into the English Channel, she was on guard duty with the force for the raid on St Nazaire in March 1942, and that August she was part of the naval force at Dieppe, where German shore batteries hit her. She went to the Mediterranean in 1943 for the Sicily landings, spent the whole of 1944 in the Adriatic, and came home for the last months of the war to the Channel where she had begun. She reached the breakers at Faslane in October 1968, the last of the wartime Hunts to go. Fourteen years later a new Brocklesby went down the slipway, in a class that had taken its names from the same fox hunts.

She carries a 30mm DS30B gun, miniguns and heavy machine guns for self-defence, alongside sonar, the SeaFox remotely operated mine disposal system and diver-placed explosive charges, the specialist toolkit that has defined her career of finding and safely destroying sea mines rather than fighting conventional engagements.

A Burned Ensign Off Cherbourg

In late March 1993, HMS Brocklesby was enforcing Britain's newly declared fishing exclusion zone around the Channel Islands when she boarded the French trawler La Calypso off Alderney for suspected illegal fishing on 28 March. Her skipper, furious at being inspected, refused to accept it and instead set course for Cherbourg with three British fisheries protection officers still aboard, in effect taking them hostage for the length of the crossing.

The wider crisis turned uglier still the following day, when a separate Royal Navy patrol vessel, HMS Blazer, was surrounded by protesting French trawlers, boarded, and forced into Cherbourg harbour, her own sixteen-man crew held below decks for three hours while furious fishermen burned her White Ensign on deck; French authorities eventually expelled the fishermen and returned the ship. La Calypso herself was finally run down by the fishery protection vessel HMS Jersey, and her master was arrested in Guernsey on 2 April, bringing a tense week-long stand-off to a close and capturing the raw tensions running through Anglo-French fishing disputes of the era, disputes that occasionally spilled over from angry words into direct confrontation on the water itself.

The Blazer half of that week deserves reading in full, because it was a great deal more serious in law than a quarrel about fishing grounds. A commissioned warship of the Royal Navy was boarded, her crew shut below decks and her colours burned in front of them, and what that actually means is set out in the article on HMS Blazer. The patrol vessel that finally ran La Calypso down, HMS Jersey, spends her entire working life in those waters and has her own account of the argument, which has never really been settled.

Clearing the Way Into Umm Qasr

HMS Brocklesby earned a battle honour for her role in the 2003 invasion of Iraq, when she was among the first coalition ships into the port of Umm Qasr, working as part of a group that cleared a mined channel into the harbour, opening it to sea access for the vital humanitarian and military supplies that would follow, an achievement recorded in her battle honours simply as "Al Faw, 2003".

Brocklesby served as control vessel for a pair of unmanned SWIMS (Shallow Water Influence Minesweeping System) boats that led the clearance column up the approach channel, working alongside the American command ship USS Dextrous, which gathered data and plotted seabed contacts for the wider task group to investigate, precisely the kind of dangerous, methodical work that mine countermeasures vessels exist to perform, done at the leading edge of a major coalition operation rather than in the relative safety of home waters.

Opening Misrata's Port Under Gaddafi's Guns

HMS Brocklesby had set off at the start of 2011 on what was meant to be a routine six-month posting to Standing NATO Mine Countermeasures Group 1, patrolling European and Mediterranean waters and dealing mostly with unexploded ordnance from wars long past rather than wars in progress. The rapidly unfolding Arab Spring changed that: she was reassigned at short notice to support Operations Unified Protector and Ellamy off Libya, and by May 2011, during the Libyan civil war, was conducting mine-clearing operations at the port of Misrata after forces loyal to Colonel Gaddafi had laid mines specifically to block the delivery of humanitarian aid to the besieged city.

Using her sonar and the SeaFox system, HMS Brocklesby located and destroyed a mine some 1.6 kilometres from the harbour entrance, directly enabling aid deliveries to reach a population that badly needed them, and putting her ship's company back in live mine-clearance work within range of enemy artillery and rockets for the first time since Al Faw in 2003.

Her commanding officer said afterwards that the crew were extremely proud to have used their skills and knowledge to open the port, and HMS Brocklesby returned to Portsmouth on 5 July 2011 flying a Jolly Roger flag, the traditional Royal Navy mark of a successful mission, in commemoration of the mine's destruction. Her 155-day stint earned the ship's company the Mine Warfare Trophy and Surface Fleet Efficiency Pennant, awarded by Rear Admiral Duncan Potts and Captain Mark Durkin as Britain's best minehunter of the year out of a fleet of fifteen, a pennant previously held by HMS Blyth.

Still on Duty

HMS Brocklesby left Portsmouth on 28 June 2018 for Bahrain, forward-based there for the next three years as part of Operation Kipion, the Royal Navy's long-standing mine countermeasures and maritime security presence in the Gulf. Rather than sail home between deployments, her ship's company rotated in and out by air every few months, Crew 6 of the 2nd Mine Countermeasures Squadron, nicknamed "the Mavericks", clocking up six full crew changes and 18 operations and exercises, among them Operation Tuwaiq, a combined UK, US, Saudi, Emirati and Bahraini effort to reassure merchant shipping and the region's fishing dhows that coalition navies were watching the sea lanes. In December 2020 she joined the Royal Saudi Navy's Al-Shaqra and the American mine countermeasures ship USS Dextrous, the very ship she had coordinated with off Umm Qasr seventeen years earlier, for a four-day combined exercise directed from Saudi Arabia's Mine Warfare Centre at Jubail.

By the time Brocklesby finally came home in October 2021, under Lieutenant Commander Dan Lee, she had steamed some 150,000 nautical miles since leaving Portsmouth in 2018. Rather than fly her crew home one last time, Lee brought the ship herself back the long way, a 6,000-mile passage via Gibraltar, Sardinia, Crete, Muscat, Djibouti and Oman that included a stop at the last known position of HMS Eagle in the western Mediterranean, to pay respects to the 131 men lost when the carrier was sunk in 1942. Waiting on the jetty in Portsmouth were around 100 family members, the first traditional dockside homecoming the Royal Navy had been able to hold since the pandemic began, and Lee himself was first down the gangway to be met by his wife and two daughters.

The stop at HMS Eagle's last position was not a detour of convenience. Eagle was an aircraft carrier, torpedoed by U-73 on 11 August 1942 while covering the Malta convoy of Operation Pedestal, and she rolled over and went down in about four minutes, taking 131 of her company with her. A minehunter of 750 tons stopping her engines over that spot on the way home from three years in the Gulf is the kind of thing the Royal Navy does quietly and does not make a great deal of noise about, and it is worth recording that she did it.

Across four decades of service, from a diplomatic flashpoint off Cherbourg to opening a besieged Libyan port to humanitarian aid, HMS Brocklesby has repeatedly demonstrated exactly the kind of quiet, technical proficiency that defines the best of the Royal Navy's mine countermeasures fleet.

Back at Sea, 2026

HMS Brocklesby's three-year refit, which fitted new autonomous and remote/offboard minehunting systems, wrapped up in spring 2026, continuing a role she had already begun during her Gulf years helping develop the very technology now expected to replace her own generation of crewed minehunters. She left Portsmouth for sea trials on 26 March, delivering on the early-2026 return to service the ship had been expecting, and was back off Portsmouth by mid-April.

Out of Service by 2031

In 2026, defence minister Luke Pollard confirmed to Parliament that all five of the Royal Navy's Hunt-class minehunters, Ledbury, Cattistock, Brocklesby, Middleton and Hurworth, will be phased out as crewed vessels by 2031, as autonomous mine-countermeasures systems take over their role.
