HMS Chiddingfold is a Hunt-class mine countermeasures vessel of the British Royal Navy. She was launched in October 1983 by her sponsor, Lady Anne Kennon, and formally entered the service of the Royal Navy in October 1984. Chiddingfold is a minehunter, and her purpose is to find and destroy mines, not only in a time of war but also in peacetime. There are about a quarter of a million mines still active from the Second World War alone and they pose a major threat to both military and civilian ships. Chiddingfold is able to enter some types of minefields without the mines detonating. This is because she is made of glass-reinforced plastic and all fixtures within the ship are made of non-ferrous metals, keeping the ship's magnetic signature to the bare minimum.
