HMS Redpole (P259) was built in 1974 by Fairmile Marine at Berwick-upon-Tweed as RAFV Sea Otter, the third Seal class Long Range Recovery and Support Craft of the Royal Air Force Marine Branch. The Seal class was similar to the Bird-class patrol vessels of the British Royal Navy. .[2]
In anticipation of the disbandment of the RAF Marine Branch in 1986, Sea Otter was transferred to the Royal Navy on 30 October 1984. At Brooke Marine, Lowestoft, she was refitted - given armaments, a light grey livery, an enclosed wheelhouse and extended bridge wings, and modified several times over the years to help her in her role patrolling Northern Ireland.[1]
As part of the cuts in the defence budget, Redpole was replaced in 1994 by a River-class minesweeper and was subsequently earmarked for disposal.[1]
The ship was sold in 1996 and spent four years in Southampton. The ship was sold again in 2000 to a founder of Digex, renamed RV Badtz Maru (after Bad Badtz-Maru), and moved to Baltimore, Maryland.[1][3]
Since 2012, as Seaman Guard Virginia, she has participated in anti-piracy patrols conducted by maritime private military contractor AdvanFort in the Gulf of Aden.[1]
