Wing 4) is an Israeli Air Force (IAF) base, located in central Israel near kibbutz Hatzor Ashdod after which it is named.

[1] The airbase was opened in 1942 as RAF Qastina by the Royal Air Force of the United Kingdom in the then British Protectorate of Palestine.

On the night of 25 February 1946, Irgun militants attacked the airfield and destroyed several parked RAF Handley Page Halifax transport aircraft.

[8] The 105 Squadron "Scorpion" was founded in 1950 at Ramat David Airbase and initially flew the English Spitfire, later the US P-51 Mustang and the French Dassault Mystère IV.

[9] The 109 Squadron "The Valley" was founded in 1951 under a different name at Tel Nof Airbase and was relocated to Hatzor from 1952 to 1956, where it flew the de Havilland Mosquito purchased from the British as a fighter-bomber and reconnaissance aircraft.

[11][12] In the first 18 years of the newly founded State of Israel, there were only the airbases of Tel Nof, Ramat David and Hatzor, which had been taken over by the British, with the latter usually being used to station the newest and most powerful fighter jets.

[13] In April 1956, Operation Shacharit (Morning Prayer in Judaism) began with the delivery of Dassault Mystère IV jets from France to Israel.

[14] Since Hatzor Airbase is located in a valley between two streams – which are dry most of the year – flooding has occurred repeatedly since its founding, affecting military equipment.

[16][17] This is also a reason why the last two squadrons of manned fighter aircraft at Hatzor were relocated to Ramat David Airbase in northern Israel in 2021.

Since 2010 Hatzor has a network of eight fighter aircraft simulator pods which use satellite footage of countries including Lebanon and Syria to train pilots for deep strike missions.
