The ship was affectionately called "The FID", because her namesake was the first Secretary of Defense, FID standing for "First In Defense". This is also the slogan on the ship's insignia and patch. She was also informally known in the fleet as the "USS Zippo" and "Forest Fire" or "Firestal" because of a number of highly publicized fires on board, most notably a 1967 fire in which 134 sailors died and 161 more were injured.
