Islamic Republic of Iran Air Force

A series of purges and forced retirements resulted in the manpower of the service being halved between February 1979 and July 1980, leaving the IRIAF ill-prepared for the Iran–Iraq War (also called the "1st Persian Gulf War"). The sudden Iraqi air strikes against eight major Iranian airbases and four other military installations, launched on the afternoon of 22 September 1980, came as a complete surprise and caused a shock in the IRIAF.

The Iranians retaliated with operation Kaman-99 which involved 206 F-4, F-5 and F-14 aircraft.

On 23 September 1980, Iran launched Operation Kaman 99 as 40 F-4 Phantoms, armed with Mark 82, Mark 83 and Mark 84 bombs and AGM-65 Maverick missiles, took off from Hamadan. After refueling in mid-air the Phantoms reached the Iraqi capital Baghdad, where they attacked: al-Rashid, al-Habbaniyah and al-Kut airbases.

Meanwhile, eight More F-4s took off from Tehran and launched a second attack on the al-Rashid airbase.

Iran proceeded to launch 58 F-5E Tiger IIs from Tabriz, which were sent to attack Mosul Airbase. After the attack on Mosul Airbase, another 50 F-5Es were dispatched to strike Nasiriyah Airbase, which was heavily damaged.

As all 148 Iranian F-4s and F-5s had been sent for a bombing raid on Iraq, 60 F-14 Tomcats were scrambled to defend Iranian airspace against a possible Iraqi retaliation. Iranian F-14s managed to down 2 Iraqi MiG-21s (1 MiG-21RF and 1 MiG-21MF) and 3 Iraqi MiG-23s (MiG-23MS), an Iranian F-5E also shot down an Iraqi Su-20 during the operation. Iraqi MiG-23s managed to down 2 F-5Es, while Iraqi MiG-21s also downed 2 F-5Es. Iraqis also by mistake shot down one of their own Il-76MD strategic airlifters with a SA-3 SAM.

The Iraqis however were well prepared for the attack and had flown over most of their air force to other Arab countries, such as Saudi Arabia, this made sure that most of the Iraqi Air Force survived the operation.

Saddam Hussein and the Iraqi military were dealt a heavy blow when Iranian Air Force vulnerabilities failed to materialize. All Iraqi airbases near Iran were out of order for weeks and, according to Iran, Iraq's aerial efficiency was reduced by 55%. This allowed Iranians to regroup and prepare for the upcoming Iraqi invasion.

Although the readiness rates of the IRIAF significantly increased in the following months, its overall role and influence declined, as the clerical government prioritized resources for the Islamic Revolutionary Guard Corps (IRGC) militias and simultaneously attempted to develop a separate air arm for this service.

After the successful liberation of most Iranian areas captured by the Iraqis in the first half of 1982, the situation of the IRIAF changed completely. From an air arm that was offensive by nature, it was largely relegated to air defense and relatively infrequent bombing attacks against targets of industrial and military significance inside Iraq. Simultaneously, the IRIAF had to learn how to maintain and keep operational its large fleet of U.S.-built aircraft and helicopters without outside help, due to American sanctions. Relying primarily on antiquated equipment purchased from the US in the 1970s, the Iranians began establishing their own aerospace industry.

During 1984 and 1985, the IRIAF found itself confronted by an ever-better organized and equipped opponent, as the Iraqi Air force—reinforced by deliveries of advanced fighter-bombers from France and the Soviet Union—launched numerous offensives against Iranian air bases, military bases, industrial infrastructures, powerplants, oil-export hubs, and population centers. These became better known as "The Tanker War" and "The War of the Cities". To defend against an increasing number of Iraqi air strikes, the IRIAF leaned heavily on its large fleet of Grumman F-14 Tomcat interceptor fighters. Tomcats were mainly deployed in defense of the strategically important Khark Island (main hub for Iranian oil exports), and Tehran. Over 300 air-to-air engagements against IQAF fighters, fighter-bombers, and bombers, were fought in these areas alone between 1980 and 1988.

Confronted with the fact that it could not obtain replacements for equipment lost in what became a war of attrition against Iraq, the IRIAF remained defense-orientated for the rest of the conflict, conserving its surviving assets as a "force in being". From mid 1987, the IRIAF found itself confronted also with U.S. Navy fighters over the Persian Gulf. A number of confrontations that occurred between July 1987 and August 1988 stretched available IRIAF assets to the limit, exhausting its capability to defend Iranian air space against Iraqi air strikes.

Despite limitations and sanctions, the IRIAF achieved an extremely successful kill rate in air-to-air combat against Iraqi jets, to the point that in air-to-air engagements, Iran's kill ratio was roughly 5:1, which is only surpassed by the Israelis against Syria in 1982 and the US in the Gulf war in 1991. Very often, air engagements consisted of one or two Iranian fighters engaging four, or even eight Iraqi fighters and winning. It got to the point where Iraq ordered its pilots to avoid air-to-air engagements (especially with the F-14).[4] There are incredible instances, during the first years of the war, that document the fact that multiple times, the Iranian pilots engaged invading Iraqi jets in dogfights almost unarmed, with the Iranians only dodging Iraqi missiles until the Iraqis retreated or were shot down with the jets close range cannon. This was done in order to preserve precious air to air munitions, like the AIM-7 Sparrow, AIM-9 Sidewinder and the famous AIM-54 Phoenix, which at that time were scarce in the air force stockpile. With this brutal air fight during 8 consecutive years, many Iranian fighter pilots, claimed world records during the war, such as General Yadollah Khalili, who holds the worldwide record of the longest straight flight in a fighter plane, having flown an F-14 non-stop for 11 hours, thus having had to do aerial refuelling 8 times during the process,[5] or like Fereydoun Ali Mazandarani, who holds the record for being the first pilot to do aerial refuelling in an F-14 in a night environment. As a result of this war, the IRIAF developed proven tactics and skillful battle tested pilots, thus becoming one of the most experienced air arms in the region. Thhe most notable Iranian fighter pilots were Fereydoun Ali Mazandarani, Fazlollah Javidnia, Jalil Zandi and Shahram Rostami . Other notable pilots include, Hossein Khalatbari, Abbas Doran, Hassan Harandi, Abolfazl Mehreganfar, Ghafour Jeddi, Abbas Babaei and Ali Eghbali Dogahe among many others.

Immediately after the end of the Iran–Iraq War, the IRIAF was partially rebuilt through limited purchases of MiG-29 fighters and Su-24 bombers from the Soviet Union, as well as F-7M and FT-7 fighters from China. While providing needed reinforcement to the Iranian Air Force, these types never replaced the older, U.S.-built F-4 Phantoms, F-14s (the IRIAF is now the only air arm in the world using the fighter), or F-5s. Instead, the IRIAF continued its efforts to keep these types in service, and began a number of projects to refurbish and upgrade them.

During the 1991 Persian Gulf War, numerous Iraqi pilots flew Iraqi Air Force aircraft to Iran to avoid destruction by coalition forces. The Iranians impounded these aircraft and never returned them, putting them in service in the IRIAF[6] and claiming them as reparations for the Iran–Iraq War. The aircraft included several Mirage F1s, MiG-23s, MiG-29s, Su-20s, Su-22Ms, Su-24s, Su-25s and a number of Il-76s, including the secret, one-off AEW-AWACS Il-76 "ADNAN 1" prototype.

Even after the cease-fire with Iraq, the IRIAF carried out several air raids against Kurdish bases in northern Iraq. The first of such raids was conducted using eight F-4s armed with rockets and cluster bombs on 6 April 1992 against People's Mujahedin of Iran's Camp Ashraf. During this event one F-4 was shot down by either insurgent or Iraqi military AAA and both pilots (Lt. Col Amini and Cpt. Sharifi) were captured and not freed until 1998. Despite threats of response, Iraq was not able to retaliate due to its own fight against Kurdish separatist guerrillas and the Western-imposed no-fly zones that crippled and limited its air force's operations.[7][8]

In 2007, Iraq asked Iran to return some of the scores of Iraqi fighter plans that flew there ahead of the Gulf War in 1991.[9] And as of 2014, Iran was receptive to the demands and was working on refurbishing an unspecified number of jets.[10][11] In late 2014, Iran returned 130 military aircraft to Iraq.[12]

In 2006, after Iranian media published a series of reports suggesting that Venezuela was interested in selling its 21 F-16 Fighting Falcons to Iran,[13] a Hugo Chavez adviser confirmed to the Associated Press that "Venezuela's military is considering selling its fleet of U.S.-made F-16 fighter jets to another country, possibly Iran, in response to a U.S. ban on arms sales to President Hugo Chávez's government". In response, Sean McCormack, a U.S. State Department spokesperson, warned Venezuela that "without the written consent of the United States, Venezuela can't transfer these defense articles, and in this case F-16s, to a third country".[14]

Iran Air Forces training in Tehran, 2014

According to Moscow Defense Brief, Russia delivered 6 Su-25UBK ground attack fighter-trainers, 12 Mi-171Sh military transport helicopters, 21 Mi-171 transport helicopters, and 3 Mi-17B-5 medical helicopters to Iran between 2000 and 2006. A $700 million repair and modernization program of the IRIAF MiG-29 and Su-24 fighters was also completed.[15]

On 22 September 2009, an IRIAF Il-76 collided with an F-5E[16] shortly after an annual parade in Tehran and crashed near Varamin, killing all seven people on board.[17]

At the end of 2014, there was evidence that the IRIAF was involved in the 2014 military intervention against the Islamic State of Iraq and the Levant. A video released by Aljazeera seemed to show an Iranian F-4 Phantom II bombing some ISIS buildings in Diyala Governorate.[18]
