The Islamic Republic has been lately more open to supply information and in showing aircrafts, but sometimes mixing realty with propaganda. Good photos of F-5s have surfaced thanks to local information agencies
(sometimes maybe photoshopped) and aviation enthusiasts.
Various very detailed information have been published by Tagweeh Babak in British (mainly) and French aviation magazines.
To calculate the local (Iranian) calender deduct 621 to the Gregorian (Western) calender.

Transitional Period 1979-1980

Much of the Air Force equipment was grounded due to the unrests in the latter half of 1978 and for most of 1979; a high number of personnel had left the country and many others were no more available. Foreign
technicians had been withdrawn, while the new government assumed an anti-Western stance. The new Air Force nevertheless inherited the equipment and structure of the former Imperial one.

A non-Imperial Provisional Govenment was established afteer the departhure of the Shah of Iran on 16-01-79 but it lived shortly. The Islamic Republic of Iran was officially declared on 01-04-79, after the overthrow
of the Imperial Iranian government, almost the whole Air Force had been virtually grounded by late 1978 due to the unrests, situation improving by mid-1979.

Withdrawal of membership to the CENTO defence pact had already been announced in February 1979 as well as the cancellation of USD 7 billion worth of arms purchase, amongst which 160 F-16s foreseen as
successors to the Northrop F-5.

On 05-12-79 all licences for export of military aircraft parts to Iran were officially suspended in USA by the Office of Munitions control. Prior to this the same office refused to grant or extend licenses for export of mili-
tary equipemnt to Iran. A USA last moment offer, in order to keep friendly relations, ofmilitary supplies was turned down by Iran.It included  spare parts for McDonnell F-4, Northrop F-5 and Lockheed C-130 transports
plus Army items. Official relations were officially 
broken by USA on 07-04-80.
It is claimed that the departing American advisors wiped out the computer-based spare parts inventory control system, causing a logistical headache, which took Iran years to sort out. All these evenments brought as
a consequence a severe spare and maintenance problem for the F-5 fleet.

The war with Iraq 1980-1988
This war brought a sharp change to this situation. By end of 1979 it was reported that the Air Force had 8 Squadrons of Northrop F-5/F-5F, 1 Squadron of Northrop RF-5A and 4 Squadrons of McDonnell F-4D/F-4E
but all the units were short of high level, technical personnel and pilots, due to purges and executions.

The war with Iraq was lumbering. Starting from beginning of 1980 friction along the 800 miles long Iraqi/Iranian border took place, initially limited to small arms and artillery shells and flights along the borders.
According to US sources in 1980 five Iraqi interceptor squadrons had limited all-weather capability, equipped with MiG-21s, ground support was given by 12 Squadrons (4 equipped by MiG-23, 3 with Sukhoi Su-7,
4 with Sukhoi Su-20 and 1 with Hawker Hunters, plus two bomber Squadrons.

The skermishes evolved into full war on 22-09-80 when Iraqi MiG-21s and MiG-23s attacked 10 Iranian air bases in an attempt to destroy the Air Force on the ground. This failed, mainly because most of the aircrafts
were in specially strengthened hangars and within a few hours Iranian fighters attacked two Iraqi Air Bases. A total of approximately 140 F-5E and 20 Northrop F-5F were available. According some spources three
Northrop F-5were destroyed toger one Hawk missille installation at Dezful by the first wave of 12 MiG-23BN.

Operation "Kaman 99" was organised for the next day as a response to the aggression; 48 F-5Es from Tabriz AB participated, attacking Mosul AB in northern Iraq and 40 F-5Es heavily damaged Nasiriyah AB in
southern Iraq.  One report mention the participation of "only" 40 Northrop F-5E, F-5F from Tabriz AFB and Vahdati AFB.

All available personnel (mainly young, at any level) was mobilised; the operation's target was to cause as much damage as possible to the enemy while saving the aircrafts on both parties, as there were no replacement
ones and little spares available. Every damaged F-5 was repaired as quickly as possible or, if not possible, stored/cannibalised
(to keep others flying) or were repaired after the war in thousands of working hours.
Northrop RF-5As deployed to three bases undertook reconnaissance flights; by 1979 only approximately seven/nine, four of these were operational. Some were kept for later Iranian use, ex 12th TFS, being stored at

Spare parts were bought through any possible source, arms dealers and from other F-5 users, but in the later years the own aircraft industry could supply some locally manufactured parts.

Main duty of F-5E Squadrons was initially to attack advancing Iraqi armor in Southern and Central flat desert war fronts with CBU cluster bombs, heat bombs, napalm bombs as well as to attack ground targets like bridges
with 500 lbs bombs; second duty was interception. These duties remained throughout the war.

Iran and Iraq generally sought to conserve their aircraft though there were F-5 combats against Iraqi MiG-21s and MiG-23s with losses on both parts, in addition to losses due to anti-aircraft fire during ground attack opera-
tions; the number of F-5s available for combat continually decreased reaching about 65 serviceable by beginning of 1983 and
about 40-45 by October 1985.

Reports also indicate that Ethiopia was the source of an unknown number of aircrafts. This varies according the source between
only 11 F-5s of an unknown mix or 8 F-5A, 2 F-5B  and 4 F-5E bought in June 1985 at an initially
extremely high price, USD 68m, later reduced to USD 34m; also possible the sale of only 4 Northrop F-5E at a total cost of USD68m in June 1985 (average was 490 hours flown) entering service in 1988 after their refur-
bishment was completed. It seems that the Air Force would have preferred not to accept the aircrafts at all after seeing the first ones. No confirmed details are known, as all involved parties prefer to keep silence.
This deal is confirmed with the sighting in April 2009 of 3 Northrop F-5A and of 1 Northrop F-5E in September 2009.

A book containing much information about the air war is "Iranian Tigers at War", by Babak Taghvaee, Helion Co. Ltd ISBN 978-1-910294-13-0.

Losses of Northrop F-5 since 1971 can be found in site. Here 31 F-5s are listed as lost during the war. Unconfirmed reports estimate that a total of approximately 90 aircrafts were lost and
67 left-over, four of which heavily damaged but reconstructed later by the Ovj Industry.
Also unconfirmed is the information that one F-5E pilot deserted in 1983 to Turkey and one in 1984 to Saudi Arabia. Both aircrafts were returned to Iran later. Some aircrafts were recovered by Boeing CH-47C Chinook after
having been damaged by Iraqi anti-aircrafts fire.

Estimates of the Center for Strategic and International Studies in October 2000 were that 60 Northrop F-E5/F-5F were availablet, but worn-out, obsolete with serious problems due to lack of updates and parts. Many of the
damaged Northrop F-5s were stored in bits and pieces or as incomplete airframes.

Islamic Revolutionary Guards - Guards Suicide Squadron
This is a special Corps formed to defend the Islamic Revolution. Some Guards were trained to fly and it has been reported that during the conflict they planned in 1983 suicide missions against the US Fleet in the Persian Gulf.
The Squadron was scheduled to fly McDonnel F-4s, but these were too precious to be lost in such missions; they obtained 3 F-5As, 4 F-5B and 1 F-5E, it seems in poor conditions. Training on these aircrafts was at Bandar
AB (Otober 1983). The attacks never happened and the Squadron was
disbanded within a relatively short time, returning the aircrafts to the Air Force.

After the conflict (from 1988)

A Logistic Support Centre of the Islamic Republic was established at London to by-bass the USA embargo and buy arms and spare parts for all Iranian armed forces branches; Great Britain had never forbidden negotia-
tions, sale or shipment parts to Iran, even if sale-export of military equipment to Iran/Iraq was outlawed.
This was correct in 1987, but shipment of spare parts for the Northrop F-5 was confiscated in January 1984.

Most of the remaining fighter force was grounded due to lack of spare parts, being damaged or being only limited mission capable. Reconstruction of all damaged airframes, some of them under cannibalisation, started
at the Oji complex in order to make the approximately 60 remaining airframes operational.

Mikoyan MiG-29s and Shenyang F-7/FT-7 were bought from Russia and China to re-equip some Squadrons. Chinese experts accompanied the Chengdu F-7, tried to learn about USA made equipment (Northrop F-5s
locally used) but were mainly interested in the Grumman F-14 and particularly in the AIM-54A air-to-missiles trying to gather as much information as possible. They had to leave Iran.

A new maintenance system allowing to bulid spare parts for the Freedom Fighter was put in service in early 2018, complete maintenance and overhaul of the Northriop F-5 series has been taking place at Tabriz AB, now
named Shaheed Fakouri AB.
The country received eleven Northrop F-5E in 1990 from Vietnam, parts of these enable the assembly of two "new" aircrafts.

Two Northrop F-5B and two RF-5A were placed in storage approximately 2006 and usad for spare parts source, but were sent to Mehrabad F-5 repair center in 2009 and redelivered to the Air Force in December 2010
after overhaul and several modifications.

Some losses are also known:
Two Northrop F-5B, part of the "Simorgh" aerobatic team were lost early '90s; one aircraft (type?) from Vahdati AB on 10-05-07. A collision with fatal consequence happened on 22-09-09 between 1 Northrop F-5E
and 1 Northrop F-5F of the 21st Tactical Fighter Squadron; another 21st TFS Northrop F-5E was lost on 09-09-11 during the military exercise in Northwestern Iran (Tabriz). 
One Northrop F-5F crashed in an attempt to
land at Dezful AB on 26-08-18, pilot killed, 1 survived.


Iran Aircraft Industrial Aircraft Industy was awarded in 2008 to modenize 47 Northrop F-5E, 16 Northrop F-5F; this was accomplished very slowly as the first one flew only in 2018 only and in 2020 the last 3 Northrop F-5F (known as Kowsar, see Iran-upgrdes).


Regular aerial parades above Teheran's sky and particularly Mehrabad AB take place on the Army Day (18th Apr) and on 22nd September (Anniversary of the start of the Iraq war), while exercises are mainly held in
September/October. Air shows and open days take also place, especially at Vahdati AB. Photography is at these events allowed, giving much information.

The yearly parades are very importat to the regime to show to the population and to show abroad the Iranian military power. Aircrafts participating are mainly based at Teheran-Mehrabad (1st TFB).

The 2007
National Army Day parade took place on 22-04-07 with the participation of 3 Saegeh.

The 2008 National Army Day (April 17th) was the biggest ever; a total of 23 Northrop F-5E and F-5F participated to a flypast: 1 F-5A, 15 F-5E, 7 F-5F, in addition to 10 locally modified versions (see Iran Upgrades page).
Some are shown hereunder:

The parade on 22-09-09 brought six Northrop F-5E, 9 F-5F from Tabriz AB (
2nd TAB) and Dezful (4th TAB) plus 2 Northrop F-5B from Izfahan (8th  TAB) and 4 Saegeh over Teheran's sky.

Three Saeqeh, three Northrop F-5F from the 21st Tac tical Fighter Squadron, one Northrop F-5F of the 42nd TFS were to participate to the 2012 edition on April 17th but only the last mentioned aircraft could partici-
pate due to poor weather at Tabriz AB, while on 17-04-11 25 Northrop F-5E, 4 Simmorgh, 4 Azarkash and 4 Saergeh participated to it.

Three Saeqeh and three Northrop F-5F participated to the parade on 18-04-14 while 2 Saergeh I (of six built) were present in November 2018 at the Kish Island airshow. together with 1 Saergeh II two-seater.

A massive exercise was held in October 2010 in Western and Central Iran called "Modafeen Harim Velayat".

The "Milad-e-Noure-Velayat 2" 2010 edition was between August 4th and 7th from Tabriz AB; Northrop F-5s, 3 Azkharashs were present together with McDonnel F-4 Phantoms, Chengdu F-7s and Sukhoi Su-24s.
They practiced aerial gunnery, hitting air-to-ground targets and perform overnight operations.

Northrop F-5s, Azarakhsh and Saeqeh participated between September 7th and 15th, 2011 to the main phase of the "Fadayeen-e Harim-e Vellayat 3" (Defenders of Velayat Sanctuaries) exercise in the Tabriz area
(Northwestern iran) together with McDonnel F-4s, Sukhoi Su-24s and Mig-29s; reconnaissance, attack missions, night raids on fixed and mobile target. A Sidewinder fired by a Northrop F-5 during the exercise was

Present and future availability
At present the IRIAF employs both two-seat F-5Bs/Simhorgs, single-seat F-5A and modified RF-5A without cameras for advanced flight training and fighter weapons training roles for its future F-4 Phantom II,
F-14 Tomcat and F-5E/F Tiger II pilots. In contrast to other US-built aircraft in the IRIAF inventory, numbers of active Freedom Fighters actually increased after 1979’s Islamic Revolution. Estimated by August 2019
were 31 Northrop F-5E and  F-5F in service.

Some (at least 2 Northrop F-5E) were based in an Forward Operating Base in Birjand province
de to tension between Iran and the Taliban/Afghani fighters. The tension still existed in 2023, when the group ha already
seized power in Afgahnistan.

On 25-06-20 the two-seater Kowsar (Thunderbolt -officially built from scratch in Iran, see Iran upgrades) were officially deivered to the Air Force in a ceremony. They formed a new aerobatic team (not named);
the last one was the Golden Crown aerobatic Team in 1978 during the Imperial era.

Revealed on 01-02-13 was a project for a future firghter aircraft named Qaher-313 (Conqueror-313 in Farsi), locally develloped/built by the Aviation Industries Organization; it has low observable features, carrying
