The Royal Navy deliberately describes Argus as a primary casualty-receiving ship rather than a hospital ship. Formal hospital-ship status would require conspicuous identification, position reporting, and restrictions imposed by the laws of war. Argus instead remains an RFA auxiliary that can carry weapons or embarked military forces while offering medical capacity close to Role 2-plus and, in some respects, Role 3. Her precise capability depends on which facilities and units are activated for a deployment. The distinction trades the special protection of a hospital ship for operational flexibility and concealment.

Why RFA Argus is a casualty-receiving ship, not a hospital ship
Argus carries advanced medical facilities while retaining the legal and operational flexibility of an armed auxiliary rather than accepting protected hospital-ship status.
