HMS Hurworth (M39): The Minehunter Whose Divers Earned Gallantry Medals

A Notably Durable Design

HMS Hurworth, the tenth ship of her class, was built by Vosper Thornycroft at Woolston, Southampton, launched in September 1984 and commissioned on 2 July 1985, a Hunt-class mine countermeasures vessel, part of a class whose glass reinforced plastic hulls were specifically designed to minimise magnetic signature and resist the shockwaves of nearby mine explosions.

Crewed by five officers and 39 ratings, she carries the Seafox mine disposal system, a truly world-leading piece of technology that has helped keep the Royal Navy's mine countermeasures capability among the most advanced in the world, remarkable longevity for a design now approaching its fifth decade of service.

The hull is the reason she is still here, and it is worth understanding why it was such an expensive idea. A Hunt is moulded in one piece from glass reinforced plastic, the largest such hulls anybody had built when the class appeared, and the material does three things at once: it is essentially non-magnetic, so an influence mine takes no notice of her; it flexes rather than fracturing when a charge goes off nearby, so she can survive shocks that would open a steel hull's seams; and it does not corrode, which is why a ship launched in 1984 is still structurally sound. The catch was cost. Building a warship out of plastic in 1980 was a specialist business at a specialist price, and the Hunts came out as some of the most expensive vessels per ton in the world, which is why the class stopped at thirteen instead of the twenty or more the Navy would have liked. The way that hull is made, and what it does under a mine explosion, is described in the article on HMS Berkeley (M40).

Rescuing Survivors of the Herald of Free Enterprise

HMS Hurworth's crew took part in a harrowing rescue operation in March 1987, while the ship was visiting Ostend, when the ferry Herald of Free Enterprise capsized shortly after leaving the Belgian port of Zeebrugge, a disaster that claimed 193 lives and remains one of the worst peacetime maritime tragedies to affect a British-registered vessel.

Two of HMS Hurworth's divers reached the scene by helicopter while the rest of her team travelled the short distance from Ostend to Zeebrugge by road, and both divers were awarded the Queen's Gallantry Medal for their part in the rescue effort, entering freezing, chaotic waters to save survivors trapped in the stricken ferry, a remarkably brave piece of individual heroism carried out under appalling conditions. The disaster as a whole produced two George Medals, ten Queen's Gallantry Medals and two Queen's Commendations for Brave Conduct, and it says something about the scale of what Hurworth's men did that theirs were two of only ten QGMs awarded that night.

What came out of that night matters as much as what her divers did in it, and it changed British shipping. Mr Justice Sheen's formal investigation reported in July 1987 and found serious negligence by the master, the chief officer and the assistant bosun who had been asleep when he should have shut the bow doors, but it refused to stop there. The most quoted sentence in the report is that from top to bottom the body corporate was infected with the disease of sloppiness. Masters had asked repeatedly for indicator lights on the bridge to show whether the doors were shut and had been ignored, in one case with a written reply asking whether they also wanted an indicator to tell them the deck crew were awake. Within days of the disaster ferries were forbidden to leave port with their loading doors open, and the lights and closed-circuit cameras that had been refused as an unnecessary expense were fitted across the fleet. The attempt to prosecute the company for corporate manslaughter then collapsed, because the law of the day required prosecutors to identify one controlling mind, and it took another twenty years and the Corporate Manslaughter Act of 2007 to fix that. One hundred and ninety-three people died in about ninety seconds because a door was open.

Her own first taste of real mine warfare came later the same year, and it is missing from most accounts of her. In August 1987 she was one of four Hunts, with Bicester, Brocklesby and Brecon, sent out at short notice to the Persian Gulf as the Iran-Iraq Tanker War turned into a mining campaign that neither belligerent would admit to. It was not a comfortable deployment for a 615-ton minehunter capable of fifteen knots: the ships were hurriedly given radar-absorbent panelling, chaff and inflatable decoys after an Iraqi aircraft had put two Exocets into the American frigate USS Stark that May, and then sent to work in water where the threat was not only mines but aircraft, gunboats and small craft. That deployment, and what it was like, is described in the article on HMS Brecon (M29). Hurworth therefore had a busy 1987: a ferry disaster in March and a shooting war by the autumn.

The First Gulf War

HMS Hurworth deployed to the Persian Gulf for the First Gulf War in 1991, one of the first minehunters sent, working under the squadron command of the minelayer HMS Abdiel alongside sister ships including HMS Atherstone and HMS Cattistock, part of the substantial Royal Navy minehunting effort supporting the international coalition assembled to liberate Kuwait following Iraq's invasion. Together they cleared Iraqi mines from waters that coalition naval forces urgently needed to use, dangerous and painstaking work carried out under real operational pressure.

The 1991 clearance was on a wholly different scale, and the arithmetic of it is the best argument for minehunting anybody has ever produced. Iraq had laid extensive fields off the Kuwaiti coast, largely of two types: old-fashioned moored contact mines and modern Italian-designed influence mines that sit on the bottom and listen. On 18 February 1991 the American amphibious ship USS Tripoli, which was the flagship of the coalition's own mine countermeasures group, struck a contact mine and was holed below the waterline; less than three hours later the Aegis cruiser USS Princeton set off two ground mines. Between them those three mines cost perhaps five thousand dollars and did something in the order of $134 million of damage to two of the most sophisticated warships afloat. The clearance effort that followed relied heavily on the Royal Navy's Hunts, which were widely regarded as the best minehunters in the coalition, and Hurworth was among the first sent. Nobody in the Gulf that spring needed persuading that mine warfare mattered.

Three years later she used the same sonar for something entirely different, and it is missing from every account of her. In June 1994, in Kilbrannan Sound between Arran and Kintyre, Hurworth found HMS Vandal.

Vandal was a U-class submarine that had disappeared on 24 February 1943, four days after commissioning and before she had made a single war patrol, with thirty-seven men aboard. The wartime search had looked in the wrong place and she had been missing for fifty-one years. Somebody eventually cross-referenced fishermen's reports of nets snagging on an obstruction against the track she should have taken, which narrowed it to a square of seabed worth searching properly, and Hurworth was sent to look.

It is the clearest possible illustration of what a minehunting sonar is for. A set designed to find an object the size of an oil drum lying on a cluttered bottom will find a two-hundred-foot submarine without difficulty, provided somebody has worked out where to point it. She was surveyed, confirmed, and designated a war grave in 1995, and a memorial carrying all thirty-seven names was unveiled at Lochranza in May 1997.

Still on the Front Line

HMS Hurworth received a major sonar upgrade and went on to deploy repeatedly to the Persian Gulf over the following two decades as part of the Royal Navy's forward-based Bahrain minehunting force, including a landmark three and a half year continuous deployment that ended in August 2011, one of the pioneering stints of what became a six-year enduring commitment to keeping the region's shipping lanes clear.

The Bahrain arrangement that followed was a genuinely unusual way to run warships and it is worth explaining. Rather than sending a ship out, working her for six months and bringing her home, the Navy left the hulls in the Gulf permanently and flew the crews out to them, rotating ship's companies through every six months or so while the vessels themselves stayed forward-based for years at a time. Hurworth's three-and-a-half-year stint ending in August 2011 was one of the first of these, and it is the reason a handful of small ships could sustain a presence that would otherwise have needed a squadron. The tools changed over the same period: the old French-built PAP remotely operated vehicles gave way to Seafox, a small expendable drone that swims down to a sonar contact, sends back a picture and, if it is a mine, blows itself up against it. It is a considerable improvement on the previous method, which was sending a man.

That particular chapter has now closed. The Royal Navy withdrew its last crewed minehunter from Bahrain, HMS Middleton, on 28 February 2026, ending an unbroken British mine countermeasures presence in the Gulf that had lasted decades, with the role passing instead to the new autonomous systems mothership RFA/HMS Stirling Castle, commissioned to launch and recover uncrewed minehunting vehicles rather than sweep for mines herself.

Remarkably, despite her 1985 build date, HMS Hurworth remains among the most capable crewed mine countermeasures vessels afloat today, a genuine testament to the quality of her original design and to the value of the steady modernisation programmes that kept the Hunt class relevant across four decades of continuous service, even as that service now draws toward its close.

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.

The argument now being settled is whether that principle can be taken one step further. What replaces the Hunts is not another minehunter but a mothership operating uncrewed boats and underwater vehicles, the reasoning being that the only completely safe way to look for a mine is not to put anybody near it, and that a small unmanned craft costs a fraction of a purpose-built minehunter with forty-four people aboard. The counter-argument, made rather firmly by people who have done the job, is that a Hunt can also board a suspect vessel, act as a patrol ship, run a diving team, carry out a rescue and show a flag, and that an autonomous system does exactly one thing. Hurworth is the practical illustration of that case: over four decades she has hunted mines in two wars, pulled people out of a capsized ferry, worked with NATO in the Channel, crossed the Atlantic to Nova Scotia and been the centrepiece of a Norfolk town's eight hundredth birthday. Whatever comes next will be very good at finding mines. It will not do the rest of it.
