RFA "Argus" is the helicopter training vessel . Operated by the RFA on behalf of the RN. She is also equipped as a hospital ship. A role she distinguished herself in during the late Gulf operations. She replaced RFA "Engadine" which was purpose bullt as a helo training ship, but eventually proved to be too small for the newer generation of aircraft."Argus" was bought by the MoD after the Falklands thing as a Ro-Ro ship and converted quite massively into what you see today. So she's getting on a bit. But given TLC and a fair wad of cash, a good ship can be made to last a long time. BY.
