Once upon a time my ship was in Long Beach Naval Shipyard for an availability that became an extended nightmare when the boiler got damaged. The first day we had a Wardroom reception with the Yard Commander and our Captain gave him a plaque. He said in front of all of us “I know that these are usually given out at the end of a visit but we both know that by then we won’t be talking to each other.” He was correct, a couple of months into our captivity on Terminal Island it became difficult for sailors to get from the ship to the gate without getting busted. The icing on the cake might have been when the Admiral in command of our squadron sent out a message calling for the ships undergoing repair to use the time to undergo training by testing each others security. These tests were referred to by their designation in the Code Book. One of my friends went to the Master at Arms office and got a laminated ID made up with the serial number that matched the drill code, a stated purpose “To blow up your ship” in fine print and a photo of a basset hound. He then put on overalls and went to one of the other ships undergoing repair. Slowly he climbed up the gangway like regular worker hating a work day, He waved his ID at the Officer of the Deck and the Petty Officer of the Watch and asked “Where’s your boiler?” They were only to happy to give him directions and point out where the correct ladder down to the engineering spaces was. So he went down there and shoved a paper bag containing a bunch of red sticks and wire and an old clock under the boiler. Then he went back to the Quarterdeck and threw his orders onto the OODs podium. They had only one question, “When did you cross this Quarterdeck?” They needed to establish that he did it on the last watch before the current guys had taken over. We planning a return visit to put something in their COs toilet when we got a new message from the Admiral to the effect that in order to avoid interfering with shipyard operations the security drills would be suspended until further notice.
