The base is partly operated by the 407th Air Expeditionary Group. Units 1st Fighter Squadron - F-16AM/BM MLU M2 The 1st Squadron was formed in 1958 with Hawker Hunters and later equipped with F-5s then the Mirage F1 and now F-16 Fighting Falcon, which has become RJAF's primary fighter, operating with the 1st, 2nd and 6th Squadrons since 1997. The squadron’s role has changed over the years from air to ground, air to air and reconnaissance to air defense and air to ground, but is now, along with the other F-16 squadrons, the main striking force of RJAF. The 1st Squadron was the first fighter squadron and has a rich history. It participated in all the conflicts and engaged in every air battle that Jordan has fought since the squadron was formed in 1958. 2nd Fighter Squadron - F-16AM/BM MLU M6.5 The 2nd Squadron was first formed in 1958 with de Havilland Vampires then with Hunters and later in 1974 with F5As and Bs as an advanced training squadron at King Hussein Air Base, Mafraq. It subsequently flew from Amman and Mafraq as a fighter squadron, then flew again from Mafraq, renamed in 1978 as the King Hussein Air College, with the CASA C-101 as the advanced jet trainer. It is now equipped with the F-16. The 2nd Squadron has a dual job: training newly graduate pilots on F-16s and supporting the 1st Squadron operations as required. The training, which is basically a tactical conversion course, extends over 8 months, during which pilots count 76 flights, averaging 85.7 hours. 6th Fighter Squadron - F-16AM/BM MLU M3 The 6th Squadron is identical to the 1st Squadron in mission and equipment.
