The Armenian Air Force (Armenian: Հայաստանի Ռազմաօդային Ուժեր, romanized: Hayastani Razmaodayin Uzher) is the air arm of the Armed Forces of Armenia formed by independent Armenia in 1992 in the wake of the dissolution of the Soviet Union. Outside its conventional name, it has also been referred to as the Aviation Department of the Armenian Armed Forces. It is organized and equipped principally to provide Armenian ground forces with tactical air support in the form of ground attack and airlift in mountainous terrain. It provided effective support during the battles with Azerbaijan in the Nagorno-Karabakh region from 1992 to 1994.

Since 2003, the Armenian government has been funding a modernization and enlargement of the air fleet. The Armenian Air Force sports the Armenak Khanperyants Military Aviation University.

Although Armenia began taking over Soviet weapons shortly following the collapse of the USSR in 1991, it would not be until October 1992 that its nascent air force was able to conduct offensive combat operations. The first Armenian combat loss was suffered on 12 November 1992, when an Mi-24 gunship operating in support of the Armenians' Martuni Offensive was shot down near the village of Kazakh. On 23 November, two Mi-8 transports were hit by ground fire, downing one and seriously damaging another; another Mi-8 was lost on 30 December.

The Azeris initiated a new offensive on 1 January 1993, successfully cutting the Lachin corridor the following day and isolating Armenian forces in Nagorno-Karabakh from resupply from Armenia proper. The Armenian Air Force helped bring up reinforcements for a counterattack that began 7 January. The first day of this action, the Armenian Air Force suffered its worst single-day losses with an Mi-8, Mi-24 and a (possibly Russian) Su-25 shot down; the Su-25 may have been brought down by friendly fire. By the time the Azeri attack had been defeated at the end of the month, another three helicopters and possibly another fighter – reportedly a MiG-21 (and therefore probably Russian) – were lost.

In late March 1993, the Armenians kicked off a new offensive in the north aimed at opening a second supply route from Armenia. Operation Kelbajar involved a four-prong attack which was successful in routing Azerbaijan's 2nd Army Corps and securing control of the region. Armenian Air Force losses for amounted to one Mi-8 helicopter (on 16 April). No aircraft losses were suffered during the subsequent summer offensives of 1993 or in the next year's actions preceding the ceasefire of 16 May 1994.

Although Armenia began working to establish an independent Armenian armed forces as early as 1989, due to a lack of resources, suitably trained personnel and useful infrastructure, the government delayed formally creating an air force until August 1992, and commenced combat operations in October. However, this may not represent the first use of armed aircraft by the Armenians; an Azeri report states that the Armenians allegedly used modified civilian Mi-8 helicopters for bombing civilian targets in the Geranboi region of Azerbaijan in January 1990. The Azeris also claimed Armenian Mi-24 attack helicopters were employed in support of an assault on Shusha in February 1992. Azerbaijani helicopter gunships were also used in fighting in the region.

In January 1992, the General Directorate of Aviation and Air Defense Forces was created as part of the newly created Ministry of Defense of Armenia. In 1992, by order of Minister of Defense Vazgen Sargsyan, the aviation department was separated from the air defense department and became a separate structure, with a separate aviation units and subunits being created. In subsequent years, in parallel with the stages of army construction, various programs for the development and improvement of the air force were implemented. As a result of the reorganization and restructuring of the DOSAAF flying club and the "Arzni" airport and their transfer in 1992 to the Ministry of Defense, the Aviation Training Center was founded. According to its December 1992 declaration for the Treaty on Conventional Armed Forces in Europe, Armenia had inherited only three operational combat aircraft and at least 13 armed helicopters from the former Soviet Union, along with a portion of its air defense network. The armed helicopter came from the former 7th Guards Helicopter Regiment and were taken over in 1991. The identities of the three combat aircraft are uncertain, but may have included one MiG-25 interceptor and two Su-25 ground-attack aircraft, probably from the former Soviet 80th Fighter-Bomber Aviation Regiment at Sitalçay air base in Azerbaijan; the helicopter force comprised Mi-8 transport and Mi-24 attack versions that had been based near Yerevan, Armenia. Other aircraft reportedly taken over by the Armenians in 1991 include six An-2, one An-24 and one An-32 transports, as well as ten Yak-52 trainers.

Territorial conflicts with Azerbaijan instigated a major expansion of Armenia's air and air defense forces in 1993–1994. The bulk of Armenia's aviation-related investment, however, went to greatly strengthening the Armenian Air Defense organization. With Russian technical assistance and contributions of anti-aircraft weapons and equipment, within a year Armenia was able to integrate most of the Soviet radars and surface-to-air missiles (SAMs) left in its territory into a coherent and effective air defense system, which it officially declared operational in April 1994. Aircraft additions were few, but by the end of 1994 the Armenian Air Force's inventory had reached an estimated 5–6 operational Su-25s (one has long been non-operational) and possibly one MiG-25 combat aircraft; two L-39 and ten Yak-52 trainers; six An-2, two An-72, one Tu-134, one Tu-154 transport aircraft; and two Mi-2, seven Mi-8/Mi-17, 15 Mi-24 helicopters.
