HMS Iveston was a Ton-class minesweeper of the Royal Navy launched on 1 June 1954 by Philip and Son in Dartmouth.

[4] As built, Iveston was powered by two Mirrlees diesel engines, giving a total of 2,500 shaft horsepower (1,900 kW).

[5] 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).

[7] Her magnetic sweep gear was removed and Type 193 Sonar was fitted to detect mines which could then be destroyed by divers[1] while active rudders incorporating electric motors were fitted to aid slow speed manoeuvrability,[8] and the ship's engines replaced by two Napier Deltic diesel engines rated at 3,000 brake horsepower (2,200 kW).

[9][10] She was recommissioned on 16 October 1964, joining the 1st Mine Counter Measures Squadron based at Port Edgar on the Firth of Forth.
