Object description

Trials ship, HMS CUMBERLAND initiates her "Pre-wetting" system during testing in the Mediterranean. Pre-wetting was the method of using large numbers of water jets to spray the entire outer surface of the ship in preparation for encountering an area contaminated with radioactive 'fall-out'. The continual spray would not only make the surface wet, thereby preventing radioactive particles from sticking, but also wash them off. The ship is nearly obscured by spray.


HMS CUMBERLAND initiates her "pre-wetting" system designed to remove radioactive fallout, during testing in the Mediterranean, September 1955.
