Survey ship HMS Echo become the first Royal Navy ship to visit Libya since the fall of Colonel Gaddafi. HMS Echo, in the final stages of a 19-month mission to gather ocean data and update nautical charts in waters east of Suez, began her Libya visit with firefighting and damage control demonstrations, tours of the ship, and an extensive look at Echo's impressive hydrographic and oceanographic survey equipment which just a short time before had discovered an underwater 'mountain' the size of Gibraltar in the Red Sea.
