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. 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. 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.
Israel apologized for the attack, saying that the USS Libertyhad been attacked in error after being mistaken for an Egyptian ship. Both the Israeli and U.S. governments conducted inquiries and issued reports that concluded the attack was a mistake due to American communications faliure which caused Israeli confusion about the ship's identity, though others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate.
In May 1968, the Israeli government paid US$3.32 million(equivalent to US$23.4 million in 2017) to the U.S. government in compensation to the families of the 34 men killed in the attack. In March 1969, Israel paid a further $3.57 million ($23.8 million in 2017) to the men who had been wounded. In December 1980, it agreed to pay $6 million ($17.8 million in 2017) as the final settlement for material damage to Liberty itself plus 13 years of interest.
