HMS Chiddingfold (M37) is a Hunt-class mine countermeasures vessel of the Royal Navy, built by Vosper Thornycroft, launched in 1983, and commissioned in 1984. With a glass-reinforced plastic hull for low magnetic signature, she displaces around 750 tonnes, measures 60 metres in length, and is equipped with advanced sonar and SeaFox mine disposal vehicles for detecting and neutralising sea mines, alongside offshore patrol capabilities. Chiddingfold spent over five years forward-deployed in the Persian Gulf until January 2024, when she collided with sister ship HMS Bangor in Bahrain harbour due to a propulsion fault, sustaining minimal damage herself. Returned to the UK via heavy-lift ship in April 2025, she has been placed in extended readiness as of early 2026, not officially decommissioned but serving primarily as a source of spare parts to sustain the remaining operational Hunt-class vessels amid the Royal Navy's transition to autonomous minehunting systems.
