The USS Liberty incident was an attack on a United States Navy technical research 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.[3] The combined air and sea attack killed 34 crew members (naval officers, seamen, two Marines, and one civilian), wounded 171 crew members, and severely damaged the ship.[4] At the time, the ship was in international waters north of the Sinai Peninsula, about 25.5 nmi (29.3 mi; 47.2 km) northwest from the Egyptian city of Arish.[1][5]
Israel apologized for the attack, saying that the USS Liberty had been attacked in error after being mistaken for an Egyptian ship.[6] Both the Israeli and U.S. governments conducted inquiries and issued reports that concluded the attack was a mistake due to Israeli confusion about the ship's identity,[2] though others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate.[7]
In May 1968, the Israeli government paid US$3,323,500 (US$22.5 million 2015) in compensation to the families of the 34 men killed in the attack. In March 1969, Israel paid a further $3,566,457 to the men who had been wounded. On 18 December 1980, it agreed to pay $6 million as settlement for the final U.S. bill of $17,132,709 for material damage to Liberty herself plus 13 years' interest.[8]
