USS Maddox Sonar and Radar Recordings: Destruction and Authorization (August 1964)

SUMMARY

The Gulf of Tonkin incident involved two alleged naval engagements in August 1964. The first, on August 2, 1964, saw North Vietnamese patrol boats attack the USS Maddox, an event that is widely accepted as having occurred [1]. However, claims of a second attack on August 4, involving both the USS Maddox and USS Turner Joy, have been extensively debated and later debunked by official investigations [2].

Reports from the USS Maddox itself, shortly after the alleged August 4 incident, expressed doubt about many reported contacts and torpedoes, attributing them to 'freak weather effects' on radar and 'over-eager' sonarmen [13]. A later National Security Agency (NSA) investigation concluded that the August 4 attack did not happen and that intelligence had been deliberately skewed to create a contrary impression [2]. This dossier explores whether sonar or radar recordings from the USS Maddox during August 2-4, 1964, were officially destroyed, and the circumstances surrounding such an action.

STRONGEST CASE FOR

The USS Maddox, under attack on August 2, 1964, would have generated significant sonar and radar data. If a second attack on August 4 was genuinely believed to have occurred, as U.S. officials initially stated, then all available sensor data would have been crucial for corroboration. Any destruction of these recordings, particularly if it occurred after doubts emerged about the second attack, could suggest an intentional effort to suppress evidence that contradicted the official narrative, thereby bolstering the justification for military escalation in Vietnam.

STRONGEST CASE AGAINST

Initial reports from naval vessels during chaotic combat situations, especially under adverse weather conditions, can be prone to error, as suggested by the Maddox's own review citing 'freak weather effects' and 'over-eager' sonarmen [13]. The destruction of routine operational data or the overwriting of tapes might have occurred for various reasons unrelated to a cover-up, such as standard operational procedures for data retention or equipment limitations at the time. Without specific evidence of an order to destroy these particular recordings with malicious intent, such an act remains speculative and could be attributable to procedural or technical factors.

  • Do any personnel who served on the USS Maddox or USS Turner Joy during August 1964 have documented accounts regarding the destruction or alteration of sensor data?
  • What were the standard U.S. Navy protocols for recording and retaining sonar and radar data from combat engagements in 1964, and were these protocols followed for the USS Maddox recordings?
