On 02 July 2003, the National Security Agency (NSA) released additional information relative to the 08 June 1967 attack on the U.S.S. Liberty. This release includes three audio recordings, transcripts (in English), three follow-up reports, and a U.S. Cryptologic History Report entitled "Attack on a Sigint Collector, the U.S.S. Liberty." The recordings are in Hebrew and contain time counts in English that were added by the intercept operator. The follow-up reports are summaries of the three transcripts with non-substantive chatter omitted and a compiled report that summarizes the activity and contains the text of the transcripts. The U.S. Cryptologic History Report is a less redacted version of the same document originally released in 1999.

How the information was obtained:

Within an hour of learning that the Liberty had been torpedoed the Director, NSA, LTG Marshall S. Carter, USA, sent a message to all intercept sites requesting a special search of all communications that might reflect the attack or reaction. No communications were available. However, one of the airborne platforms, a U.S. Navy EC-121, had collected voice conversations between two Israeli helicopter pilots and the control tower at Hazor Airfield following the attack on the Liberty.
