This article is about the 1980s class. For the WWI class, see Hunt-class minesweeper (1916). For other ship classes, see Hunt class.

The Hunt class is a class of thirteen mine countermeasure vessels of the Royal Navy. As built, they combined the separate roles of the traditional minesweeper and that of the active minehunter in one hull, but later modifications saw the removal of mine-sweeping equipment. They have a secondary role as offshore patrol vessels.

Development

Upon introduction in the early 1980s they were the largest warships ever built out of glass-reinforced plastic and were the last in operation to use the Napier Deltic diesel engine. All were built by Vosper Thornycroft in Woolston except Cottesmore and Middleton, which were built by Yarrow Shipbuilders Limited on the River Clyde. Quorn was the last ship of the class launched.

Following the sale of Bicester and Berkeley to the Greek Navy, the sale of Cottesmore and Dulverton to the Lithuanian Navy and the decommissioning of Brecon, a contract to re-engine the remaining eight vessels was signed by BAE Systems in 2008, whereby the existing 30-year old Napier Deltic 9-59K power units were replaced by Caterpillar CAT C32 engines, together with new gearboxes, bow thrusters, propellers and control systems, in a six-year refurbishment programme that was completed in 2018.

The capabilities of the remaining eight vessels of the Hunt class have been significantly enhanced by the installation of Sonar Type 2193 and the NAUTIS 3 command system. The performance of Sonar 2193 exceeds that of any other mine hunting sonar in service in the world today and is capable of detecting and classifying an object the size of a football at a distance of up to 1,000 metres (1,100 yd). In late 2007 Chiddingfold used the Seafox drone, the Royal Navy's mine disposal system, during Exercise Neptune Warrior off Scotland. Seafox is described by the MOD as a "state of the art fire and forget system, capable of destroying mines in depths of up to 300 metres".

The 2021 defence white paper announced that all the Hunt-class vessels would be retired from Royal Navy service in the 2020s and replaced by automated systems. It was subsequently indicated that the withdrawal would occur in the 2029 to 2031 period, though HMS Chiddingfold was already withdrawn in 2026.

In 2023, the navy began to take delivery of six REMUS 300 small autonomous underwater vehicles (SAUVs), produced by Huntington Ingalls Industries. The system is being acquired to enhance the capabilities of the Hunt-class ships and has a reported operating depth of 300 meters with an endurance time of up to 20 hours.

Ships in the class

All 13 ships of this class re-used names from the World War II Hunt-class destroyer. Four of the names had also been used for World War I Hunt-class minesweepers: these were HMS Bicester, Cattistock, Cottesmore and Quorn. HMS Atherstone had been a paddlewheel minesweeper in 1916, and Brocklesby was a coaster taken up from trade in 1916.
