The wing was founded as Fighter Wing 6 in June 1959 as the parent unit of the 61st Fighter Squadron already based at Torrejón with North American F-86F Sabre fighters. During the mid 1960s, the Air Force was reorganized and the wing renamed Ala 16 as part of the newly formed Tactical Aviation Command. The 61st Fighter Squadron was likewise renamed 161 Squadron in accordance with the Air Force's new numbering scheme. Around this time, the unit's equipment was upgraded with the arrival of 21 Lockheed F-104G Starfighter aircraft. Ala 12 acquired its current designation on 25 March 1971 and it soon began to receive the McDonnell Douglas F-4C Phantom II fighter aircraft. This permitted the F-86 to be retired from the wing with 50,000 flight hours logged on the type. Further shipments of F-4Cs led to the end of F-104 operations as well; the final F-104 flight from Torrejón took off on 25 January 1973. The F-104's service with the wing was the shortest of any fighter type, the wing only tallying 17,000 flight hours on the Starfighter. To support the ability of the F-4 to be refueled in flight, Boeing KC-97L Stratofreighters were assigned to the wing under the newly formed 123 Squadron, which remained with the wing through 1976. Reconnaissance was added to the wing's capabilities in October 1978 when 122 Squadron added four ex-United States Air Force RF-4C aircraft. 1989 marked the beginning of the wing's transition to its current equipment as the 121 and 122 Squadrons began to re-equip with EF-18A/B Hornet aircraft that remains its prime aircraft to this day. For a while, the RF-4C was retained for reconnaissance work with 123 Squadron, its complement peaking at 14 aircraft in 1995. Torrejón was also tasked with operational conversion for the Air Force's EF-18 program, and to this end, 124 Squadron was formed until the task was transferred to Ala 15 at Zaragoza. Ala 12's first major international duty came when the wing formed the core of Detachment Icarus, Spain's air contingent of Operation Deliberate Force and Operation Allied Force. This duty was shared with Ala 15, and both rotated forces through the detachment from 1995 through 2002. 123 Squadron was disbanded in October 2002 and the operation of the RF-4C came to an end with 90,000 flight hours having been logged by the wing on the Phantom II, leaving the EF-18 as the sole equipment of the wing. In November 2003, Ala 12 flight hours on the Hornet exceeded 100,000, a total greater than that flown by any of the unit's previous aircraft types. Ala 12's Hornets were the first Spanish aircraft to undergo a mid-life update, and in 2006, 122 Squadron was recognized by NATO an operational evaluation rating of "Mission Capable". 121 Squadron was deployed to Decimomannu Air Base on the island of Sardinia in Italy with four planes to constitute Detachment Argos. They provided the initial Spanish contingent of NATO forces in Operation Odyssey Dawn, the American-led portion of the 2011 military intervention in Libya, from 19–28 March 2011. Following this, they participated in NATO's Operation Unified Protector until mid-May 2011 when relieved by 122 Squadron, which was in turn relieved by Ala 15 on 6 July 2011.
