RFA Fort Rosalie is the lead ship of her class of Royal Fleet Auxiliary fleet replenishment ships. Fort Rosalie was originally named RFA Fort Grange, but was renamed in May 2000.
Fort Rosalie was laid down in 1973, by Scott Lithgow on the River Clyde, launched in 1976 and commissioned the next year.
The ship saw her first war service during the Falklands War, and also supported British forces in the Balkans alongside at the port of Split from at least 1994-2000, being based at Cervena Luka (North Port) an area just outside Split, Croatia. Fort Rosalie also oversaw repairs to HMS Tireless at Gibraltar later in 2000. She is affiliated to Tamworth and Lichfield Sea Cadets under her former name, Fort Grange.
Fort Rosalie attended the HMNB Devonport Navy Days in August 2006, representing the Royal Fleet Auxiliary.
In May 2008 the ship entered a £28 million refit at Northwestern Ship-repairers & Shipbuilders Cammell Laird yard in Birkenhead.
