HMS Walney (M104) was a Sandown-class minehunter of the British Royal Navy. She was the fourth of the Sandown-class minehunters, and the second ship to carry the name, which comes from the island off Barrow-in-Furness in Cumbria on the north-west coast of England.

Construction and design[edit]

HMS Walney was one of four Sandown-class minehunters ordered from Vosper Thornycroft on 27 July 1987.[1] She was laid down at Vosper Thoneycroft's Woolston, Southampton shipyard in May 1990, launched on 25 November 1991 and commissioned on 20 February 1993.[1][2]


On 15 May 2006, HMS Walney and HMS Atherstone discovered a 1000 lb World War II bomb whilst conducting a survey of the River Mersey.[3]

It was announced on December 16, 2009, that Walney would be decommissioned sometime in 2010.[4] She was decommissioned in a ceremony on 15 October 2010 at her homeport, HMNB Clyde. Walney called in at her affiliated town of Barrow-in-Furness on her way to her final port of call, Portsmouth naval base.[5]
