Operation Focus (Hebrew: מבצע מוקד, Mivtza Moked) was the opening airstrike by Israel at the start of the Six-Day War in 1967.

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.

[3] 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.

Meanwhile, the Egyptians hindered their own defense by effectively shutting down their entire air defense system: they were worried that rebel Egyptian forces would shoot down the plane carrying Field Marshal Amer and Lt-Gen. Sedky Mahmoud, who were en route from Almaza Air Base to Bir Tamada in the Sinai to meet the commanders of the troops stationed there.

In this event it did not make a great deal of difference as the Israeli pilots came in below Egyptian radar cover and well below the lowest point at which Egypt's SA-2 surface-to-air missile batteries could bring down an aircraft.

By the end of the first day of the Six-day War, Israel had complete air superiority over Egypt, the Golan Heights, the West Bank, and the entire Sinai desert.

[citation needed] The effectiveness of the operation showed how vulnerable fixed air base installations were to aerial attacks at the time.
