Operation Focus (, 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 operations for the duration of the war, and remains one of the most successful air attack campaigns in military history. Summary The IAF launched all but 12 of its nearly 200 operational jets in three main waves of aerial attacks, and several smaller waves in the days following the operation. A total of 452 enemy aircraft were destroyed, most of them on the ground. That left the IAF in almost complete control of the skies, and it was able to assist the Israeli Defense Forces (IDF) ground units effectively. The operational success was achieved by concentrating on the initial destruction of the runways with a new kind of weapon, a rocket assisted anti-runway warhead. The prototype French/Israeli anti-runway weapon program uses rocket braking over the target to point the warhead directly toward the runway being attacked; at a set altitude, a second accelerator rocket ignites and drives the warhead through the pavement of the runway before it detonates. The explosion creates a small crater over a large new sinkhole, meaning the damaged runway section must be completely removed before the sinkhole can be repaired rather than a normal bomb crater which is simply filled in and patched. Once the runways were disabled, entire air bases' complements of aircraft were effectively grounded and fell victim to subsequent attack waves, resulting in near-total Israeli air supremacy. Timeline 5 June 1967 Egyptian defensive infrastructure was extremely poor, and no airfields were yet equipped with hardened aircraft shelters capable of protecting Egypt's warplanes in the event of an attack. The Israeli warplanes headed out over the Mediterranean before turning toward Egypt. Meanwhile, the Egyptians hindered their own defense by effectively shutting down their entire air defense system: they were worried that rebel Egyptian forces
