September, 1982. A signalman aboard Battleship New Jersey uses a signal light to send a message to a nearby ship during sea trials, months before the battleship’s fourth recommissioning. Even in 1982, none of the Navy’s advanced communications systems were completely secure from electronic detection, but flashing lights and flags were, because they emit nothing an enemy could intercept. Today, a signal lamp is still in that same spot on the signal bridge, and guests can touch it on their way up the red line.
