The Museum displays the flag that flew at the time of the attack of the U.S.S. Liberty, a U.S. Naval Ship, on June 8, 1967, when the ship found itself in the middle of the 1967 Arab-Israeli Six-Day War. Cruising 25 miles off the Gaza coast, it was attacked by Israeli fighters and torpedo boats at 2 o'clock on a clear and sunny day. There was no apparent provocation, and the reason for the attack has never been fully resolved, although Israel described it as an identification error and sent restitution for the damage and loss of life. The U.S. government accepted the explanation of the Israeli government concerning the identification error. The loss of 34 men was the largest loss of life in a single event in American cryptologic history. It occurred, ironically, during a war in which the United States was not a participant.
