The three Hecla-class survey ships HMS Hecla, Herald and Hydra were converted to ambulance ships in service to SS Uganda. Although Hydra had been refitted to a spec similar to Uganda she settled into a role similar to her sister vessels, casualty evacuation transport from SS Uganda to Montevideo for onward flight to UK.
When the conflict ended Hydra remained as the Falkland Islands Hospital Ship until Port Stanley airport runway was repaired, thus ensuring she was the last Task Force vessel to return to the UK.
