She was transferred from the Royal Navy to Royal Air Force duties in 1966, renamed No.5002 (later No.5012) and converted to a research and trials vessel for Royal Aircraft Establishment, Farnborough. By 1972, she was the only remaining RAF-operated marine asset, and to provide continued efficient management she was transferred to the Royal Corps of Transport's civilian fleet and renamed Richard George Masters (later chortened to R G Masters).[1] Private Masters was the sole recipient of the Victoria Cross in the Royal Army Service Corps during the First World War.[2]
