Operating theatre


RFA Argus is fitted with self-defence weaponry and decoys to protect herself and her crew from harm. Because of this, and the fact that she may have operational units embarked, under the Geneva Convention she can't be classified as a hospital ship and does not display the International Red Cross symbol.

I get three months off for every four months I’m at sea. I’ve used that time to travel even more of the world – there aren’t many jobs that offer that sort of opportunity.

Middle East


Units of the Royal Navy and Royal Fleet Auxiliary have been on patrol in the Gulf since October 1980, after the Iran/Iraq conflict of that year, and more recently operations have extended further south with the increase in piracy off the Somalia coast. 


Ships, units and aircraft need periods of maintenance and sea-going trials to ensure that they are at their best for any tasks asked of them.
