HMS Medway (P223): From Chasing Caribbean Drug Runners to Guarding the Falklands

Built at Govan, Rolled Onto a Barge

HMS Medway had her steel cut at BAE Systems' Govan shipyard in Glasgow on 8 June 2015, and was launched in a rather unusual fashion on 23 August 2017: rolled onto a semi-submersible barge and lowered into the water, rather than sliding down a slipway in the traditional manner.

She was officially named on 20 October 2017, and after an especially thorough set of sea trials running from 9 November to 11 December 2018, a full 75 days, reportedly a record for the Royal Navy since the Second World War, she was transferred to the Royal Navy on 5 March 2019 and commissioned on 19 September that year at the former Chatham Dockyard in Kent, sponsored by Lady Fallon, wife of the former Defence Secretary Sir Michael Fallon.

Commissioning a ship called Medway at Chatham is a slightly bolder piece of naming than it looks, because of what happened on that river in June 1667. Charles II's treasury was empty, his sailors and his dockyard men had not been paid, and the fleet was lying at Chatham with skeleton crews aboard. The Dutch, under De Ruyter and guided in by two English river pilots who had changed sides, came up the Thames, took Sheerness, broke the great chain stretched across the Medway and set about the anchored English fleet at their leisure.

It lasted three days. Loyal London, Royal James and Royal Oak, three of the largest ships the navy possessed, were burned or sunk, and the flagship Royal Charles was simply taken in tow and sailed away to Holland as a souvenir. Her stern carving is in a museum in Amsterdam to this day. Peace was signed the following month on terms rather better than England had been hoping for a fortnight earlier, and the raid is still, by most reckonings, the worst thing that has ever happened to the Royal Navy in home waters.

Samuel Pepys, who worked for the Navy Board and therefore knew exactly how bad it was, sent his wife and his father out of London with his gold and sat down to make a will. So a patrol vessel commissioned at Chatham under the name of that river is not being sentimental about a pleasant bit of Kent. She is named for the place where the Royal Navy learned what happens when a country stops paying for its fleet.

A Batch 2 River-Class Offshore Patrol Vessel

HMS Medway is the second ship of the Batch 2 River-class offshore patrol vessels, built on the hull of the Amazonas-class corvettes BAE Systems had already supplied to the Brazilian Navy and adapted with some 29 modifications and enhancements, mostly concentrated on the combat system, damage control arrangements and helicopter-handling equipment, over the baseline Amazonas design on which the class is based, and is fitted with Kelvin Hughes SharpEye and Terma Scanter 4100 radars alongside a BAE CMS-1 combat management system, armed with a 30mm DS30B gun and machine guns, a modest but entirely sufficient armament for a vessel built primarily for patrol, interdiction and constabulary work rather than fleet action.

The design has a history of its own, and it is not a British one. Those three Amazonas hulls were not built for Brazil at all: they were ordered by Trinidad and Tobago under a contract ratified in 2007, as the Port of Spain class, and were built or very nearly built when the contract was terminated at the end of 2010. BAE was left holding three finished patrol vessels and no customer. Brazil took all three in 2012, along with support and the rights to build more, for something in the region of £133 million.

Which is the awkward part of the arithmetic. Britain ordered Forth, Medway and Trent in August 2014 for £348 million between them, and Tamar and Spey in December 2016 for a further £287 million, working out at roughly £127 million a ship against the £44 million or so a ship Brazil had paid for the near-identical originals. The gap is not really about steel. The Batch 2 order was placed when it was, and for the sum it was, largely to keep the Govan workforce employed through the gap between finishing the carriers and starting the Type 26 frigates, and shipbuilding capacity is a thing a country pays for whether or not it is bending metal that year.

What the Navy got for it turned out to be genuinely useful, which is the part the cost argument tends to skip. Every month Medway spends running down drug boats in the Caribbean or sitting off South Georgia is a month a frigate does not have to, and there are only so many frigates. That is the whole case for the class, and Medway's own record since 2019 makes it about as well as anything could.

Eighty-One Million Pounds of Cocaine

HMS Medway deployed to the Caribbean in January 2020 as part of the Atlantic Patrol Task (North), becoming the Royal Navy's permanent regional presence there, working alongside the Royal Fleet Auxiliary support ship RFA Argus.

In September 2020, working with an embarked team of 47 Commando and the United States Coast Guard, she used a spell of stormy weather as cover to close undetected on two separate smuggling vessels within 24 hours, seizing 650 kilograms of cocaine between them; combined with a further haul landed by RFA Argus's own boarding team days earlier, the wider task group's total came to cocaine valued at some £81 million on Britain's streets, according to National Crime Agency figures. She followed that in October 2022 with the capture of more than 400 kilograms of cocaine worth a further £24 million, destroying the smuggling vessel involved in the process, a particularly substantial contribution to disrupting the drug trafficking routes that run between South America and markets in North America and Europe.

Rescues, Refits and Rare Turtles

HMS Medway rescued five crew members from a sinking ocean-going tug near Sint Maarten in January 2023, one of the many unglamorous but properly lifesaving tasks that fall to a patrol vessel on continuous regional deployment.

After a period of maintenance and a temporary replacement by HMS Dauntless in 2023, she returned to the Caribbean in the autumn of 2024, during which deployment she transported rare turtles to the Azores, before undergoing further maintenance in Tampa, Florida, between December 2024 and May 2025.

She was eventually relieved in the Caribbean by HMS Trent in October 2025, and before departing assisted with relief efforts following Hurricane Melissa.

Falklands Guardship

HMS Medway had already begun taking on duties in the South Atlantic in January 2023, serving as a temporary Falkland Islands guardship while HMS Forth underwent maintenance, and conducting South Georgia sovereignty protection operations that April.

She carried out search and rescue exercises and joint training with the 2nd Battalion, The Rifles, in September 2023, and in January 2026 was officially deployed as the permanent Falkland Islands patrol vessel, replacing HMS Forth in that role outright.

Paratroopers and a Hantavirus Scare

HMS Medway transported paratroopers from 16 Air Assault Brigade to South Georgia in April 2026 to support sovereignty patrols and explosive ordnance disposal missions, and the following month undertook a seven-day transit to the remote island of Tristan da Cunha, delivering six civilian clinicians and medical supplies to help manage a potential outbreak of Hantavirus, before extracting military medics and paratroopers from the island once the mission was complete, a remarkably striking illustration of just how varied a modern offshore patrol vessel's workload can be, ranging from drug interdiction one year to remote medical logistics the next.

Still on Patrol

HMS Medway remains in active service today, permanently stationed in the South Atlantic as of early 2026, continuing her work in fisheries protection, joint exercises and humanitarian support, a modern successor to a long line of Royal Navy ships that have quietly kept watch over Britain's most far-flung territories.

A Diplomatic Row and a New Captain

On 4 and 5 July 2026, Medway sailed from the Falklands along the Argentine coast to the Chilean port of Punta Arenas, in support of British Antarctic Survey operations, berthing at the Prat pier on 5 July for her first-ever call at a Chilean port and remaining until the 8th. Argentina's Foreign Minister, Pablo Quirno, denounced the transit through Argentina's territorial sea as a "military incursion" and had a formal note of protest delivered to the British Embassy on 13 July, invoking both the 1991 Joint Declaration on military confidence-building measures and UN General Assembly Resolution 31/49, timing the announcement to land just after Argentina's World Cup semi-final win over England, days after an Argentine footballer's own Falklands-claim banner stunt following the match; Downing Street rejected the protest as covering a routine, pre-notified transit.

Command of the ship changed hands that same month, with Commander Craig Clark relieving Commander James Tibbitts MBE, and later in July her crew carried out live machine-gun firing and a man-overboard drill with an RAF A400M Atlas during Operation Southern Vigilance near the Falklands.
