HMS Dasher (P280): A Student Training Boat That Went to War in Iraq

Built by Vosper Thornycroft

HMS Dasher was built by Vosper Thornycroft and commissioned in 1988, an Archer-class P2000 patrol vessel, one of a class of small, fast patrol boats built primarily to support University Royal Naval Units around the country, giving students a genuine taste of seagoing naval life alongside their academic studies.

The scheme behind her is one of the odder and cleverer things the Royal Navy does, and it is not really about recruitment. There are fourteen University Royal Naval Units, each with a couple of training officers, a boat of its own and about fifty undergraduates who sign on for the length of their degree. They are paid, they wear the uniform, and they are categorised as RNR List 7, which means they are explicitly not reservists and cannot be called up for anything. Only a small proportion ever join the regular Navy. That is not the point. The point is that every year a few hundred people who are going to become lawyers, doctors, civil servants, engineers and journalists spend their weekends taking a warship to sea, and spend the rest of their lives knowing from the inside what a ship is and what the people in it are like. It is the cheapest influence operation in Whitehall and nobody ever calls it one.

The boats themselves are worth a note too. Sixteen of them came into service between 1985 and 1988, twenty metres long and fifty-four tonnes, moulded in glass-reinforced plastic. At that size they are the smallest commissioned warships in the Royal Navy, and commissioned is the word: a P2000 is His Majesty's Ship, wears the White Ensign, flies a commissioning pennant and has a commanding officer, exactly like a carrier, on about one four-thousandth of the displacement.

At a little under twenty metres long, she is powered by a pair of turbocharged V12 diesel engines giving a top speed of around 24 knots, carries a permanent crew of just five regular Royal Navy personnel, and can take up to a dozen students aboard at a time, proof that you do not need a very big ship to teach a great many people how to be seasick in genuinely useful ways.

HMS Dasher served for many years as the training vessel for the University Royal Naval Unit Bristol, a role she held prior to 2004 and returned to in September 2012 following various reassignments in between.

Armed and Sent to Support the Iraq War

In a particularly unusual departure from her normal training duties, HMS Dasher was transported to Cyprus aboard the ship CEC Mayflower in 2003 alongside HMS Pursuer, to support Operation Telic, Britain's military contribution to the invasion of Iraq.

For this deployment, both small patrol boats were fitted with Kevlar armour and additional weaponry, including three FN MAG machine guns, a substantial upgrade in firepower for vessels normally used to ferry university students around coastal waters rather than operate in a war zone.

The Cyprus Squadron is a genuinely forgotten formation. It was stood up in February 2003 purely because of Iraq, based at the Akrotiri Mole beside the RAF station, and it existed for seven years and two months with a total strength of two boats. What it actually did was less about Iraq than about the Sovereign Base Areas themselves: protecting visiting ships and high-value British equipment, patrolling the coastline of the two base areas, giving passing Royal Navy ships something to exercise against, and helping out the base areas' own police and customs. It was disbanded in April 2010 and both boats went to the Clyde.

HMS Dasher went on to serve as part of the Royal Navy Cyprus Squadron, established in February 2003 specifically to safeguard shipping around Britain's Sovereign Base Areas on the island, remaining in that role through until 2010, one of only two vessels, alongside HMS Pursuer, ever assigned to the squadron across its entire seven-year existence.

Guarding the Nuclear Deterrent

In April 2010, HMS Dasher and HMS Pursuer left Cyprus to become the two founding vessels of the newly formed Faslane Patrol Boat Squadron, tasked with protecting the Royal Navy's ballistic missile submarines at HM Naval Base Clyde, home to Britain's continuous at-sea nuclear deterrent since 1969, a role of genuine strategic importance for so small a vessel. HMS Raider and HMS Tracker took over the squadron in 2012, freeing Dasher to return to her more familiar duties with University Royal Naval Unit Bristol that September.

The Faslane job is the one that most deserves the phrase strategic importance, because of what it is guarding against. A ballistic missile submarine is at her most vulnerable on the surface, in the Gareloch, moving slowly between the jetty and open water, and the threat is not a foreign navy but a small fast boat with somebody determined in it. That is precisely what a twenty-metre patrol boat with a machine gun and a Royal Marines boarding party alongside is for. Dasher spent two years doing that, in the rain, in a Scottish sea loch, for a deterrent that has not been left unguarded for a single day since 1969.

There is a coincidence buried in that posting which nobody ever seems to mention. On 27 March 1943 the escort carrier HMS Dasher was exercising in the Firth of Clyde with her Sea Hurricanes and Swordfish when, at about twenty to five in the afternoon, she blew up. A second explosion threw her two-tonne aircraft lift sixty feet into the air. She sank within minutes, midway between Arran and Ardrossan, and 379 of the 528 men aboard were killed. A hundred and forty-nine got out.

There was no enemy within hundreds of miles. She was an American-built escort carrier converted from a merchant hull, launched in Pennsylvania in 1941 as the cargo and passenger ship Rio de Janeiro, and the Admiralty's own verdict on the type was that safeguards against accidents of that nature were, by British standards, practically non-existent in the petrol arrangements and hangars of these American-built escort carriers. The inquiry could not settle on a single cause. The likeliest explanation, arrived at long afterwards, is a discarded lit cigarette. The same failing killed her sister ship, and that story is told from another deck in the article on HMS Avenger (D14).

Wartime censorship closed over the whole thing within hours. Survivors were permitted to tell their families that they were alive and nothing whatever else. Twelve of the dead were buried with full military honours at Ardrossan and the rest were left where they lay, and the loss stayed largely unknown outside Ayrshire for decades. The wreck is now an official war grave and a controlled site under the Protection of Military Remains Act, which means it may not be entered at all; the first three-dimensional survey of her was made by a Royal Navy survey ship and is described in the article on HMS Echo (H87).

Which means that the patrol boat who spent 2010 to 2012 escorting ballistic missile submarines in and out of the Gareloch was working, week after week, in the same stretch of water in which the previous HMS Dasher went down with three-quarters of her ship's company still aboard. Nobody planned that, and nobody in the Royal Navy would think to remark on it. It is worth remarking on.

Her home-waters years were not entirely without incident. In July 2015, she led a flotilla of America's Cup World Series catamarans out past the Spinnaker Tower to their racing area off Southsea, a rather more colourful escort assignment than shepherding nuclear submarines, even though the AC45s themselves, capable of well over 35 knots once up on their foils, could have left her behind within moments had the race actually started early.

Gibraltar and the Baltic

HMS Dasher deployed to the Gibraltar Squadron between 2020 and 2022, returning to sovereignty protection duties around the Rock, and took part in joint exercises in the Baltic alongside allied navies in 2025, including operations involving a Royal Swedish Navy submarine, a truly wide-ranging spread of duties for a boat that spends most of her working life training the next generation of naval officers rather than operating on the front line of NATO's northern flank.

Her most notable outing yet came that autumn, as part of Exercise TARASSIS, the Joint Expeditionary Force's largest activity in its eleven-year history, spanning the High North, Norway and the Baltic through September and October 2025. On 2 October, in Tallinn Bay, Dasher and three other P2000s, HMS Pursuer, HMS Express and HMS Puncher, were formally placed under the operational control of the Estonian naval vessel EML Ugandi for a passage exercise testing just how seamlessly the two navies could work together, a genuinely useful reversal for a boat that normally does the training rather than being on the receiving end of it.

Command passed to Lieutenant Jack Mason in October 2024, and Dasher has since taken part in the Navy's own trials of the Rattler uncrewed surface vessel programme, part of a wider push to test how crewed and autonomous small craft might work together in future, a fittingly forward-looking role for a boat whose day job has always been training the officers who will eventually have to make exactly those calls.
