HMS Bangor (M109): Patrolling Libya's Coast, Then Getting Rear-Ended Twice in Bahrain

A Minehunter Built From Fibreglass

HMS Bangor is a Sandown-class minehunter that entered Royal Navy service in 2000, built with a fibreglass hull specifically to minimise her magnetic signature, since a warship built from steel is, rather inconveniently, exactly the kind of thing that attracts magnetically triggered mines.

The Sandown class does one job, and the official designation says so: single-role minehunter. Where the older Hunt class were built to sweep as well as hunt, these ships gave up sweeping entirely in exchange for being better at the finding. Fifteen were built by Vosper Thornycroft between 1987 and 2001, twelve of them for the Royal Navy and three for Saudi Arabia: fifty-two metres long, about five hundred tonnes, glass reinforced plastic throughout, and good for thirteen knots, which is slower than most things afloat and entirely beside the point.

The clever part is underneath, and it is what makes her a minehunter rather than a boat with a sonar. She has no propellers or rudders in the ordinary sense. She has Voith Schneider units: vertical blades hanging beneath the hull on a rotating disc, the pitch of each blade varying through every revolution so that thrust can be pointed in any direction at all, instantly. Add bow thrusters and a computer holding it all together, and the ship can sit exactly over a fixed point on the seabed in a running tide and stay there, while a diver or a remotely operated vehicle works on a mine beneath her. Holding station precisely, for hours, in moving water, is the entire trick of the trade.

She is fitted with Variable Depth Sonar capable of operating down to 200 metres, the Type 2093 sonar system, and carries SeaFox mine disposal equipment alongside diver-placed explosive charges for actually dealing with whatever she finds, backed up by a 30mm gun, miniguns and machine guns for self-defence.

The name has been on a minesweeper before, and the first one was ordered in a considerable hurry. HMS Bangor was laid down at Harland and Wolff's Govan yard on 19 September 1939, sixteen days after the declaration of war, and she gave her name to one of the largest minesweeper programmes of the conflict: Bangors were built for the Royal Navy, the Royal Canadian Navy and the Royal Indian Navy, and the Canadians alone ended up with something like fifty-four of them. They were not comfortable ships. A hull that shallow is tender, a hull that short buries its bow in a head sea, and a design drawn for a complement of about forty finished up carrying six officers and more than ninety ratings. The first Bangor herself was one of the small minority given diesels rather than steam, went through the whole war, and was sold to Norway in 1946 as the Glomma.

Libya, the Clyde, and the Commonwealth Games

In 2011 Bangor conducted maritime security patrols off Misrata during the NATO intervention in Libya, part of the international effort supporting operations against the Gaddafi government, and took part in Exercise Joint Warrior in 2013.

She also spent June 1944 doing something her namesake has now done as well, which is a coincidence worth spelling out. In that month the first Bangor was off Cherbourg, taking part in the bombardment of the German coastal batteries covering the port, an action in which the Hunt-class destroyer HMS Brocklesby had her ensign shot away and burned. Sixty-seven years later, in 2011, this Bangor was patrolling off Misrata during the Libyan intervention, and the ship that went into Misrata harbour under fire to open it for aid shipping was HMS Brocklesby, by then a Hunt-class minehunter carrying the same name as the destroyer. Both halves of that are set out in the article on HMS Brocklesby (M33). Two names, two operations sixty-seven years apart, and both names present at each of them.

In 2014 she was stationed on the River Clyde during the Glasgow Commonwealth Games, providing security while also offering public tours, a nice piece of community engagement for a ship whose usual work rarely brings her into direct public view.

Forward-Based in the Gulf

From mid-2021, Bangor deployed to Bahrain alongside HMS Middleton, joining the Royal Navy's 9th Mine Countermeasures Squadron and receiving an upgrade to the ORCA mine detection system, part of Britain's long-standing forward presence in the Gulf helping keep the region's vital shipping lanes clear of mines.

Five years in Bahrain deserves explaining, because a ship does not simply stay away that long by accident. The Royal Navy has kept mine countermeasures vessels permanently at Bahrain since 2006, and the arrangement is that the ships stay and the people rotate: a complete ship's company flies out, takes over from the crew going home, works her for a few months and is relieved in turn. It is a very efficient way of getting sea days out of a hull, because the ship never spends weeks crossing an ocean to get anywhere. The catch is the one that caught Bangor: when something goes badly wrong, the nearest dockyard that can put it right is eight thousand miles away.

A Run of Bad Luck in Port

Her time in Bahrain has not been without incident, and of a rather unfortunate kind: on 19 January 2024, HMS Chiddingfold, manoeuvring in harbour shortly after contractors had finished work on her propulsion system, suffered a steering fault that sent her stern-first into Bangor's port side, tearing a large breach in the fibreglass hull, though thankfully neither ship was holed below the waterline and nobody was hurt.

In August that year she suffered further damage when the American minehunter USS Gladiator, being moved without power in a routine "cold move", struck Bangor's stern, requiring dry-docking for repairs. She was eventually returned to Scotland aboard a heavy-lift vessel in November 2025 for more substantial structural repairs, with the work scheduled for completion in April 2026.

Despite the recent run of collisions, Bangor has been extended in service for a further five years, based at HMNB Clyde at the time, a reminder that even a remarkably useful minehunter is not immune to the occasional bump in a crowded harbour.

Home at Last

HMS Bangor put back to sea in late July 2026 for post-repair trials out of Rosyth, finally returning to service after more than 900 days sidelined. The Ministry of Defence's 2025-26 annual accounts have since put a price on getting her home from Bahrain: roughly £25 million in collision damage plus a further £5 million in 'fruitless payments' for the commercial heavy-lift passage back to the UK.

That thirty million pound figure is worth sitting with. It is not far off what a ship of this class cost to build, spent on repairing collision damage neither of which she caused and on hiring a heavy-lift ship to carry a five-hundred-tonne minehunter home from the Gulf on her deck. It is also, quietly, the bill for forward-basing when it goes wrong, and the reason the Ministry classifies part of it as fruitless payment is that the money bought no capability at all. Nine hundred days out of service is the other half of that price, and it does not appear in the accounts.

A Brief Return to Faslane

HMS Bangor left Rosyth on 21 August 2026 and called in at Faslane a week later, her first sight of the Clyde since departing for the Gulf back in 2021. The visit proved to be a farewell rather than a change of base: the Royal Navy has confirmed Bangor's home port going forward will be Portsmouth, where she rejoins the fleet's Mine Countermeasures Squadron.

There is a larger fact behind the five-year extension. Bangor is the last of her class left in the Royal Navy. Twelve were built for Britain; three went to Estonia, others to Ukraine and Romania, and the remainder have gone. A ship that spent nine hundred days alongside after being run into twice, and cost thirty million pounds to get home and mend, is now the only single-role minehunter the country has, which is why she is being kept rather than quietly disposed of. She moves to Portsmouth as the sole survivor of a class of twelve.
