The USS Liberty incident was an attack on a United States Navy technical research ship (a spy ship), USS Liberty, by Israeli Air Force jet fighter aircraft and Israeli Navy motor torpedo boats, on 8 June 1967, during the Six-Day War. The combined air and sea attack killed 34 crew members (naval officers, seamen, two marines, and one civilian NSA employee), wounded 171 crew members, and severely damaged the ship. At the time, the ship was in international waters north of the Sinai Peninsula, about 25.5 nautical miles (47.2 km; 29.3 mi) northwest from the Egyptian city of Arish.
Israel apologized for the attack, saying that USS Liberty had been attacked in error after being mistaken for an Egyptian ship. Both the Israeli and United States governments conducted inquiries and issued reports that concluded the attack was a mistake due to Israeli confusion about the ship's identity. Others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate. Thomas Hinman Moorer, the 7th chairman of the Joint Chiefs of Staff, accused President Lyndon B. Johnson of having covered up that the attack was a deliberate act.
