Autonomous Systems: Land & SeaBackground
HMS Chiddingfold was one of the Royal Navy's Hunt-class mine countermeasures vessels, glass-reinforced-plastic-hulled ships built to sweep and neutralise sea mines with low magnetic and acoustic signatures. Commissioned in 1984, she served for 42 years, including deployments protecting shipping through the Strait of Hormuz and the wider Gulf.
She was retired from the Royal Navy on 13 July 2026, alongside the Type 23 frigates HMS Richmond and HMS Iron Duke, with her mine-hunting duties passing to autonomous and remotely operated underwater vehicles and to the newer Type 26 and Type 31 frigates.
Her withdrawal was the first crewed mine-countermeasures hull the Royal Navy has actually decommissioned since committing to an autonomy-led replacement doctrine, tying that transition to a firm timetable rather than a future promise, at the same moment the UK is funding new mothership tonnage to carry the uncrewed systems taking over her role.
