The first base established in Jordan, The King Abdullah I Air Base (KAAB), which houses the RJAF's Headquarters, is situated in East Amman’s Marka area.

It was RAF's Amman base from 1922 until 1948. The Arab Legion Air Force, the ancestor of the RJAF, then shared the facilities until 1957 when the RAF handed it over to the Jordanians.

His Majesty the late King Abdullah I presented the first flying wings to Jordanian pilots in 1951 at this Base.

KAAB was the first RJAF's Air Base and home to the first two operational fighter squadrons.

In 1952, new runways and facilities were built and expanded in order to operate day fighter/ground attack squadrons. On January 19, 1954 King Hussein formally inaugurated the new runway with a circuit in his twin-engined Dove.

KAAB was also the main international airport until 1982 with the runway extended in the early 70s to accommodate larger aircraft.

KAAB is home to the Air Lift Wing, which was established in 1971 and until recently, the Wing comprised 5 squadrons: 3rd, 7th, 8th, 14th and 15th, in addition to the Royal Squadron, before a series of disengagement decisions were taken to relocate the 8th, 14th and 15th to King Abdullah II Base in Ghabawi to the east of Amman.

The base is also where the Jordan Air Ambulance Center is located to serve Jordanians and residents by providing air medical evacuation of the critically injured and ill from peripheral and remote hospitals to centers of excellence in Amman, where more advanced medical service can be obtained.

A squadron of MI-26, the largest helicopter in the world, joined the Wing in 2018, but was also relocated to the same Base later in that year.

The Prince Faisal Technical College, the Police Helicopter Wing and the Gliding Club are also based there.

A civilian airport, two air academies and two facilities run by the Air Force – Jordan Aeronautical-Systems Company (JAC), which provides MRO services to C-130s and other aircraft, and Jordan International Air Cargo (JIAC), share the facilities.
