HMS Iveston (M1151)

HMS Iveston was a Ton-class minesweeper of the Royal Navy, formerly of the Second Mine Countermeasures Squadron.[1][2] She has been decommissioned and now operates as the training ship T.S. Iveston. Iveston was built by Philip and Son in Dartmouth and launched on 29 June 1955.[3] In 1965, Iveston was commanded by Mark Ruddle, a former submariner.[4] 24 years later Christopher Ameye was appointed in command until 1992 when Iveston was decommissioned.[5] On 19 July 1968 HMS Iveston joined "Reclaim" at a salvage area, and was withdrawn the next day.[6] After her decommissioning, HMS Iveston became the Sea Cadet training ship T.S. Iveston, in 1993.

Construction and design

Iveston was ordered on 19 March 1952,[7] was laid down at Philip and Son's Dartmouth yard on 22 October 1952, was launched on 1 June 1954 and commissioned on 20 June 1955.[8][9]

She 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.[10] As built, Iveston was powered by two Mirrlees diesel engines, giving a total of 2,500 shaft horsepower (1,900 kW). These engines gave a speed of 15 knots (17 mph; 28 km/h).[11] 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).[10][11]

Armament consisted of a single Bofors 40 mm anti-aircraft gun forward and two Oerlikon 20 mm cannon aft.[10][11] Minesweeping equipment included wire sweeps for sweeping moored contact mines and acoustic or magnetic sweeps for dealing with influence mines.[12] The ship had a crew of 27 in peacetime and 39 in wartime.[11]


From 1956 to 1962 Iveston was laid up in operational reserve at Hythe, near Southampton. On 3 January 1963 she was towed to Devonport dockyard where she was refitted and converted to a minehunter.[13] Her magnetic sweep gear was removed and Type 193 Sonar was fitted to detect mines which could then be destroyed by divers[7] while active rudders incorporating electric motors were fitted to aid slow speed manoeuvrability,[14] and the ship's engines replaced by two Napier Deltic diesel engines rated at 3,000 brake horsepower (2,200 kW).[15][16] She was recommissioned on 16 October 1964, joining the 1st Mine Counter Measures Squadron based at Port Edgar on the Firth of Forth.[17]


There was a mutiny on board HMS Iveston at Ullapool on July 5, 1970. This was the last mutiny in the Royal Navy [18]. Five of the crew were tried by court martial at Rosyth and convicted. The group were sentenced to detention for terms ranging from 12 to 21 months, and dismissed from the Royal Navy "with disgrace". One of the ratings was convicted of an additional charge of striking a superior officer [19] [20]

Sea Cadet use

T.S. Iveston is now under the control of the Sea Cadet Corps. She berthed in Tilbury Docks as a training base. Iveston is used mostly by Thurrock Sea Cadets who use her weekly, although training is also available for Sea Cadets from Essex, Greater London and more recently Southern and Eastern areas.[21][22] The training available can be for marine engineering, seamanship, canoeing, pulling, sailing, powerboating, cook/steward and instructors’ courses.[22]

Iveston was in desperate need of more accommodation, so the help of B&T Lifting of Tilbury and Lowes Metals of Grays was enlisted to remove the winch from the ship to make room for a portable building. There are now two other containers on the quay, where Iveston is berthed, which are used as additional classrooms.[21]

Due to the increase in the health safety requirements plus the soaring increased costs to maintain the structural and internal integrity of the vessel Thurrock Sea Cadets put the vessel out to tender and with no other interested parties they eventually sold the vessel to a Tilbury Pilot but sadly in March 2015 the vessel was sold to the breakers yard at Erith on the River Thames.
