British patrol ship opens fire off Falkland Islands amid rising tensions with Argentina

A British warship permanently stationed in the South Atlantic has fired 120 live rounds off the coast of the Falkland Islands as part of a military exercise amid heightened tensions with Argentina over the archipelago.

HMS Medway, a River-class patrol vessel deployed to guard the islands, unleashed the salvo from its primary 30mm automatic cannon during sea trials designed to certify the crew for front-line operations.

The crew described the drills as routine training.

The ship’s company wrote on X: “120 rounds downrange. We took the opportunity for further routine training and put our 30mm Automatic Small Calibre Gun through its paces again. Practice = Precision.”

The naval exercise follows a string of joint manoeuvres across the archipelago, including Operation Southern Vigilance, in which the vessel fired heavy machine guns along the edge of the Falkland Islands Conservation Zone and trained alongside RAF transport aircraft and the Parachute Regiment.

British Forces South Atlantic Islands described the deployments as an essential visible deterrent, intended to demonstrate London’s “enduring commitment” to defending the overseas territory against any potential adversaries.

The drills come as Argentina intensifies its diplomatic offensive over the islands – which it calls the Malvinas – more than four decades after the 1982 war.

Under right-wing president Javier Milei, Argentine officials have repeatedly protested against British military movements in the region, branding UK patrols an illegal provocation.

Diplomatic tensions have been further inflamed following a direct challenge from Buenos Aires over the Sea Lion oilfield, a 1.7-billion-barrel deposit north of the islands due to begin extraction in 2028.

Argentina has lodged a formal case with the International Tribunal for the Law of the Sea in Hamburg seeking to halt the project, blocking British-authorised drilling and threatening sanctions against participating British and Israeli energy firms.

Prime minister Andy Burnham has said he will do “whatever it takes” to keep the Falkland Islands British, insisting the UK will “stand firm in the face of any threats” to the sovereignty of the islands and insisting the position will never change under his leadership.

The 2,000-tonne HMS Medway remains the only Royal Navy vessel permanently stationed in the region, forming part of a broader British garrison at RAF Mount Pleasant that includes Typhoon fighter jets, Sky Sabre air defence batteries, and a permanent infantry detachment.
