Royal Navy patrol ships HMS Spey and HMS Tamar are to enter the South China Sea for a ten-day multinational exercise with Australia, Malaysia, New Zealand and Singapore, continuing a British naval presence in waters where Beijing has repeatedly objected to UK military activity and policy, according to the Royal Navy.
The two Batch 2 River-class offshore patrol vessels will take part in Exercise Bersama Lima 26, the annual tri-service exercise conducted under the Five Power Defence Arrangements, or FPDA, which links the United Kingdom with Australia, Malaysia, New Zealand and Singapore.
Bersama Lima, meaning “Together Five” in Malay, will involve ships, aircraft and troops operating across maritime, land and air scenarios. Forces committed to the exercise include frigates, patrol vessels, a corvette, tanker and submarine, as well as divers and specialist boarding teams.
Australian F-35A Lightning II fighters will lead the air element of the exercise, while planned scenarios include troops directing naval gunfire, boarding and searching vessels at sea, anti-submarine warfare and naval air defence supported by participating air forces.
The deployment takes place against a long-running dispute between Beijing and several regional governments over territorial and maritime claims in the South China Sea, as well as wider disagreements over the activities of military forces from countries outside the region. China has repeatedly criticised British involvement. In 2018, Beijing said it had lodged stern representations with the UK after HMS Albion sailed close to the Paracel Islands, which China calls the Xisha Islands. China said the ship had entered waters it regarded as its territorial sea without permission, while Britain has consistently maintained the importance of navigational rights under international law.
Beijing again objected in 2021 as the UK increased its naval presence in the Indo-Pacific, accusing Britain of deploying its Carrier Strike Group to the South China Sea to “flex its naval muscles”. More recently, in July 2026, the Chinese Embassy in London strongly condemned the UK for joining an international statement supporting the 2016 South China Sea arbitration award and urged Britain to stop what it described as “stirring up trouble” in the region.
HMS Tamar has also recently conducted a freedom-of-navigation activity in the South China Sea. In a parliamentary answer published on 8 September, the Ministry of Defence confirmed that the patrol ship operated alongside the Royal Australian Navy on 1 September as part of the UK’s stated commitment to freedom of navigation and overflight under the UN Convention on the Law of the Sea.
The Royal Navy says HMS Spey and HMS Tamar have themselves conducted freedom-of-navigation missions in disputed waters during their five-year deployment to the Indo-Pacific, sometimes operating independently and sometimes alongside regional partners.
Before Bersama Lima moves into its main operational phase, personnel from the five participating nations will spend time familiarising themselves with different vessels, equipment, procedures and terminology, while senior officers carry out planning for the live exercise.
According to a Royal Navy news update, Lieutenant Commander Cheryl Goodwin, HMS Tamar’s Executive Officer, said: “We’re looking forward to being a part of Bersama Lima 26 – an exercise which unites some of our closest allies, tests the crew in a traditional war-fighting role, and demonstrates the UK’s resolve to maintain stability in the Indo-Pacific region through supporting our partners.”
HMS Tamar is also carrying a Royal New Zealand Navy boarding team during the exercise, adding another element of direct integration between the participating forces.
