Abu Sultan Air Base (LG-209) is an airbase of the Egyptian Air Force located approximately 19 km south-southeast of Ismailia (Al Isma`iliyah); 116 km northeast of Cairo, Egypt. It was formerly a major Royal Air Force station known as RAF Deversoir built before the Second World War.

The remaining RAF units vacated Deversoir following the coup that saw Gamal Abdel Nasser seize power in June 1956.

The base is home to both 30 and 56 Squadrons which fly the Aérospatiale SA-342L Gazelle.

Deversoir was a Royal Air Force (RAF) military airfield built in the 1930s. It was built part of the defences of the Suez Canal, being constructed at the northwest shore of the Great Bitter Lake. During the Second World WAr, it was used as a military airfield by the RAF and the United States Army Air Forces during the North African campaign against Axis forces.

The airfield received United States President Franklin D. Roosevelt on 12 February 1945 as he flew from the Yalta Conference to rejoin the USS Quincy, which was anchored in the Great Bitter Lake and would host the President's meetings with King Farouk of Egypt, King Abdulaziz of Saudi Arabia, and Emperor Haile Selassie of Ethiopia before transporting him back to the United States.

Deversoir was used by the RAF after the war until March 1955 when it was handed over to the Egyptian Air Force. Modern hardened aircraft shelters were built on wartime-era dispersal pads, and recent runway markings are evident in aerial photography. The airbase is being used to accommodate a helicopter unit flying Aérospatiale SA-342L Gazelle, armed helicopters.

RAF Deversoir was operative as No. 324 Fighter Wing from 24 August 1948 when it was the home of three squadrons of de Havilland Vampire aircraft plus three Gloster Meteors, one to each squadron. The squadrons were numbers 213 and 249. Some time near the end of WW2 the station had been used to house Italian prisoners of war and this was evidenced by a painting done by one of them which was present in 1950 – 1952 in one of the cookhouse dining room for other ranks.

During the mid-1950s Canal Zone patrols were carried out by RAF jets from the station. A rotation of standby aircraft from the station's Vampire squadrons was put in place, with RAF jets frequently scrambled to intercept Egyptian air force aircraft. This included Meteors and Constellations.

Relations between the United Kingdom and Egypt continued to deteriorate in the wake of the 1952 revolution.

213 (Fighter) Squadron, the last RAF flying squadron based there, disbanded at Deversoir on 30 September 1954, with the pilots and ground crew dispersed to other RAF stations outside Egypt.
