HMS Shoulton (M1182) was a Ton-class minesweeper of the Royal Navy.

Construction and design

Shoulton was ordered on 17 June 1952 and was launched at Montrose Shipyard, Montrose, Scotland on 10 September 1954.[1] She was completed on 16 November 1955, commissioning with the pennant number M1182.[2]

Shoulton was 152 feet (46.33 m) long overall and 140 feet (42.67 m) between perpendiculars, with a beam of 28 feet 9 inches (8.76 m) and a draught of 8 feet 3 inches (2.51 m). Displacement was 360 long tons (370 t) normal and 425 long tons (432 t) deep load.[3] Like all the Ton-class, the ship had an Aluminium-framed wooden hull. She was powered by a pair of Napier Deltic diesel engines which drove two shafts, giving a total of 3,000 shaft horsepower (2,200 kW) and a speed of 15 knots (17 mph; 28 km/h).[1][4] 45 tons of fuel were carried, giving a range of 3,000 nautical miles (3,500 mi; 5,600 km) at 8 knots (9.2 mph; 15 km/h).[3][4]

Armament consisted of a single Bofors 40 mm anti-aircraft gun forward and two Oerlikon 20 mm cannon aft.[3][4] Minesweeping equipment included wire sweeps for sweeping moored contact mines and acoustic or magnetic sweeps for dealing with influence mines.[5] Unlike earlier ships of the class, Shoulton was fitted with an enclosed bridge.[4]


In 1957, Shouton was converted into a prototype minehunter by Vosper Thornycroft at their Woolston, Southampton works.[6] In November 1960, Shouton was part of the 50th Mine Sweeping Squadron and in July 1963 joined the First Minesweeping Squadron[a] as the Senior Officer's ship.[6] From 1965 to 1967, Shouton was refitted with a prototype Pump-jet propulsor.[6] The installation was successful, proving resistant to damage (managing to survive a railway sleeper entering the pump-jet without damage to the propulsor), and paved the way for pump-jets being used on the Royal Navy's nuclear submarines.[5] Shoulton together with sister ships Clarbeston and Invermoriston, took part in salvage operations following the crash of an Aer Lingus Vickers Viscount airliner off Rosslare.[6]

On 28 July 1977, Shouton took part in the Review of the Fleet at Spithead commemorating the Silver Jubilee of Elizabeth II as part of the 3rd Mine Countermeasures Squadron (3rd MCMS).[6] She transferred to the 2nd Mine Countermeasures Squadron (2 MCMS) in January 1979 and paid off for the last time at Portsmouth on 23 November 1979.[8]

Shoulton was sold for scrapping on 2 February 1981[9] and was broken up in Blyth from 17 April 1981.[6]
