Hunt-class mine countermeasures vessel

The Hunt class is a class of thirteen mine countermeasures vessels of the Royal Navy that combined the roles of the traditional minesweeper and the active minehunter in one hull, with a secondary role as offshore patrol vessels. On entering service in the early 1980s they were the largest warships ever built of glass-reinforced plastic and the last to use the Napier Deltic diesel engine. Vosper Thornycroft built all but two at Woolston, and the two exceptions, Cottesmore and Middleton, were built by Yarrow Shipbuilders on the Clyde, ordered in January 1979. Re-engining with Caterpillar diesels finished in 2018, and the class is due to leave service between 2029 and 2031.
