Operation Focus (Hebrew: מבצע מוקד, Mivtza Moked) was the opening airstrike by Israel at the start of the Six-Day War in 1967. It is sometimes referred to as the "Sinai Air Strike". At 07:45 on 5 June 1967, the Israeli Air Force (IAF) under Maj. Gen. Mordechai Hod launched a massive airstrike that destroyed the majority of the Egyptian Air Force on the ground. Following Syrian and Jordanian attacks in retaliation, the Israeli Air Force proceeded to bomb air bases in those countries. By noon, the Egyptian, Jordanian and Syrian Air Forces, with about 450 aircraft, were destroyed. It was also very successful in disabling 18 airfields in Egypt, hindering Egyptian Air Force operations for the duration of the war, and remains one of the most successful air attack campaigns in military history.
