319. Telegram From the Director of the National Security Agency (Carter) to the White House 1
Washington, June 22, 1967,
1454Z.
SIGINT Readiness Bravo “Crayon” Report Nr. 2149.
Aftermath of Israeli Attack on USS Liberty, 8 June 1967.
1. General
The following activity is based on Israeli plain language VHF/UHF voice communications intercepted on 8 June 1967 between 1229Z and 1328Z. This activity deals solely with the aftermath of the attack by [Page 542] Israeli jet aircraft and torpedo boats on the USS Liberty (GTR5). There are no COMINT reflections of the actual attack itself.
2. Summary
At 1230Z, two Israeli helicopters 810 and 815, were dispatched by Hatsor to the area of the incident to check for survivors of an unidentified “warship.” Approximately at 1234Z, the air controller at Hatsor clarified the identity of the ship to the two Israeli helicopters by informing them that it had been identified as Egyptian. At 1239Z, Hatsor told the helicopters that it was an Egyptian cargo ship.
At 1307Z, Hatsor told helicopter 815 to take any survivors that spoke Egyptian to El Arish ((31–08N 34–54E)), but if they spoke English to take them to Lod ((31–58N 34–54E)).
At 1312Z, the Israeli helicopter 815 apparently informed Hatsor on a different frequency that it had sighted an American flag on the ship. Hatsor then asked the helicopter to make another pass to check “if this is really an American flag.”
The helicopters and the MTBs were communicating on a UHF frequency whereas the helicopters and the air controller at Hatsor were using VHF throughout. At 1310Z, helicopter 815 informed the MTB using callword “Pagoda” that the ship was not in danger. The same helicopter then reported that G.T.R.–5 was written on the ship and inquired if this meant anything. The MTB replied in the negative.
Throughout this intercept, the USS Liberty is referred to as the “big one” while the three Israeli motor torpedo boats are referred to as the “small ones.” The helicopters used call signs 810 and 815. The air controller at Hatsor Air Base used call word “Tribune.” The MTBs used callwords “Thorn,” “Pagoda,” and “Crisis.” The callword “Jewel” is not identified, but may be Haifa.
