The ship, whose crew was under command of the National Security Agency, was intercepting communications at the height of the Six-Day War when it came under direct Israeli aerial and naval assault.
Reverberations from the torpedo blast sent crewman Ernie Gallo flying across the radio research room where he was stationed. Gallo, a communications technician aboard the Liberty, found himself and his fellow shipmates in the midst of an attack that would leave 34 Americans dead and 171 wounded.
This week marks the 50th anniversary of the assault on the USS Liberty, and though it was among the worst attacks in history against a noncombatant U.S. naval vessel, the tragedy remains shrouded in secrecy. The question of if and when Israeli forces became aware they were killing Americans has proved a point of particular contention in the on-again, off-again public debate that has simmered over the last half a century.
