India is the largest operator of MiG-21s. In 1961, the [[Indian Air Force]] (IAF) opted to purchase the MiG-21 over several other Western competitors. As part of the deal, the Soviet Union offered India full transfer of technology and rights for local assembly.<ref name= Santosh>Mehrotra, Santosh.

Due to limited induction numbers and lack of pilot training, the IAF MiG-21 played a limited role in the [[Indo-Pakistani War of 1965]].<ref name=Canberra>Rakshak, Bharat.

Since 1963, India inducted more than 1,200 MiG-21s into its air force. As of 2024, around 40 MiG-21s are known to be in operation with the IAF.<ref>{{Cite web |title=Another MiG-21 Squadron Retired: The Curtain Is Closing on IAF's Most Abiding Fighter |url=https://thewire.in/security/mig-21-squadron-retired-curtain-closing-iaf-most-abiding-fighter |access-date=2024-06-16 |website=The Wire |language=en}}</ref> At its peak, IAF operated 400 MiG-21s in 19 squadrons.<ref>{{Cite web |date=2002-09-16 |title=LCA economics |url=https://www.hinduonnet.com/thehindu/biz/2002/09/16/stories/2002091600190300.htm |url-status=dead |archive-url=https://web.archive.org/web/20090317030448/http://www.hinduonnet.com/thehindu/biz/2002/09/16/stories/2002091600190300.htm |archive-date=2009-03-17 |access-date=2024-08-31 |website=[[The Hindu]]}}</ref>

Because of the performance of India's MiG-21s, several nations, including [[Iraq]], approached India for MiG-21 pilot training. By the early 1970s, more than 120 Iraqi pilots were being trained by the Indian Air Force.<ref name=autogenerated3>Cooper 2004 {{Page needed|date=May 2013}}.</ref>

===Indonesia===
[[File:MiG-21F-13-Fishbed-C.jpg|thumb|Indonesian Air Force [[MiG-21]] in the [[Dirgantara Mandala Museum|Yogyakarta Air Force Museum]]]]
The [[Indonesian Air Force]] purchased 22 MiG-21s. In 1962, 20 MiG-21F-13s and MiG-21Us were received during [[Operation Trikora]] in the Western New Guinea conflict. Indonesian MiG-21s never fought in any dogfights. Right after the U.S.-backed anti-communist forces took over the government, 13 Indonesian MiG-21s were delivered to the U.S. in exchange for T-33, UH-34D, and later, F-5 and OV-10 aircraft. All remaining MiG-21s were grounded and retired due to a lack of spare parts and the withdrawal of Soviet maintenance support.

The MiGs were added to the [[4477th Test and Evaluation Squadron]] ("Red Eagles"), a [[USAF]] aggressor squadron at Tonopah Test Range.<ref>Davies 2012, p. 48.</ref>

The MiG-21 was designed for very short [[ground-controlled interception]] (GCI) missions. It became renowned for this type of mission in the skies over [[North Vietnam]].<ref>Michel 1997, p. 81.</ref> The first MiG-21s arrived directly from the Soviet Union by ship in April 1966. After being unloaded and assembled<ref>Toperczer 2001, pp. 6, 77.</ref> they were given to the [[Vietnam People's Air Force]]'s (VPAF) oldest fighter unit, the 921st Fighter Regiment (921st FR), which had been created on 3 February 1964 as a MiG-17 unit. Because the VPAF's 923rd FR was newer and less experienced, they continued to operate MiG-17s, while the arrival of the MiG-19s ([[Shenyang J-6|J-6]] versions) from China in 1969 led to North Vietnam's only MiG-19 unit, the 925th FR. On 3 February 1972, North Vietnam commissioned its fourth and last fighter regiment created during the war with South Vietnam, the MiG-21PFM (Type 94)-equipped 927th FR.<ref>Toperczer 2001, p. 27.</ref>

Former MiG-17 pilot [[Nguyễn Nhật Chiêu|Nguyen Nhat Chieu]] and his [[wingman]] Tran Ngoc Siu intercepted [[United States Air Force|USAF]] [[Republic F-105 Thunderchief|F-105Ds]] while on [[Combat Air Patrol|CAP]] duty over [[Phúc Yên Air Base|Phuc Yen Airbase]] (a.k.a. Noi Bai Airbase) on 7 July 1966, shooting down one piloted by Capt. Tomes with a salvo from Tran's [[UB-16 (rocket pod)|UB-16-57]]/[[S-5 rocket|S-5M]] unguided rocket-equipped MiG-21, while flight leader Nguyen was unable to establish a lock on another, wildly-evading F-105 with his R-3S AAM; this was the first instance of a VPAF MiG-21 shooting down a piloted enemy aircraft in the Vietnam War.<ref>Toperczer, 2015, pp. 52. The standard pair of MiG-21s was more successful in combat at the time when fitted with a mix of infra-red guided R-3S AAMs carried by the flight leader with the wingman carrying UB-16-57 rocket pods with unguided S-5M air-to-air missiles... , a dissimilar pair of MiG-21s scrambled from the 921st Fighter Regiment on CAP duty over Noi Bai against F-105D Thunderchiefs... repeated salvos of rockets from Tran Ngoc Siu's MiG-21 destroyed Capt. Tomes' F-105D, however Nguyen Ngat Chieu was unable to lock his R-3S AAMs against another F-105D making energetic evasive manuevers... this was basically the first aerial victory by a MiG-21 over piloted American aircraft.</ref>

Although 13 of North Vietnam's [[flying aces]] attained their status while flying the MiG-21 (cf. three in the MiG-17), many VPAF pilots preferred the MiG-17 because the high [[wing loading]] of the MiG-21 made it relatively less maneuverable and the lighter framed canopy of the MiG-17 gave better visibility.<ref>Toperczer #25 2001, p. 12.</ref> However, this is not the impression British author Roger Boniface got when he interviewed Pham Ngoc Lan and ace [[Nguyen Nhat Chieu|Nguyễn Nhật Chiêu]] (who scored victories flying both the MiG-17 and MiG-21).<ref>Toperczer #25 2001, p. 88.</ref><ref>Toperczer #29 2001, p. 84.</ref> Pham Ngoc Lan told Boniface that "The MiG-21 was much faster, and it had two [[K-13 (missile)|Atoll]] missiles which were very accurate and reliable when fired between 1,000 and 1,200 yards."<ref>Boniface 2005, p. 190.</ref><ref>Michel 1997, pp. 41, 78, 153.</ref> And Chiêu asserted that "...&nbsp;for me personally, I preferred the MiG-21 because it was superior in all specifications in climb, speed and armament. The Atoll missile was very accurate and I scored four kills with the Atoll.&nbsp;... In general combat conditions, I was always confident of a kill over an [[F-4 Phantom]] when flying a MiG-21."<ref>Boniface 2005, p. 192.</ref><ref>Michel 1997, pp. 83, 155.</ref>

Although the MiG-21 lacked the long-range radar, missiles, and heavy bomb load of its contemporary multi-mission U.S. fighters, its [[RP-21 Sapfir]] radar helped make it a challenging adversary in the hands of experienced pilots, especially when used in high-speed hit-and-run attacks under GCI control. MiG-21 intercepts of [[Republic F-105 Thunderchief]] strike groups were effective in downing US aircraft or forcing them to jettison their bomb loads.

====Aerial combat victories 1966–1972====

The VPAF flew their interceptors with guidance from ground controllers, who positioned the MiGs in ambush battle stations to make "one pass, then haul ass" attacks.<ref name="Michel III 42 43">Michel III pp. 42, 43</ref> The MiGs made fast and often accurate attacks against US formations from several directions (usually the MiG-17s performed head-on attacks and the MiG-21s attacked from the rear). After shooting down a few American planes and forcing some of the F-105s to drop their bombs prematurely, the MiGs did not wait for retaliation but disengaged rapidly. These "guerrilla warfare in the air" tactics<ref name="Michel III 42 43"/> generally proved successful during the war. In December 1966, the MiG-21 pilots of the 921st FR downed 14 F-105 Thunderchiefs without any losses.<ref>{{cite web |url= http://acepilots.com/vietnam/viet_aces.html |title= Vietnamese Aces – MiG-17 and MiG-21 pilots |work= Ace pilots |access-date= 9 August 2013 |archive-date= 23 January 2013 |archive-url= https://web.archive.org/web/20130123111248/http://acepilots.com/vietnam/viet_aces.html |url-status= dead }}</ref>

The USAF and the US Navy had high expectations of the F-4 Phantom, assuming that their massive firepower, best available on-board radar, highest speed and acceleration properties, coupled with new tactics, would provide an advantage over the MiGs. But in confrontations with the lighter MiG-21, F-4s began to suffer losses. From May to December 1966, the USAF lost 47 aircraft, destroying only 12 VPAF fighters in return. From April 1965 to November 1968, over 268 air battles occurred over the skies of North Vietnam. North Vietnam claimed 244 downed U.S. aircraft while admitting to the loss of 85 MiGs. Of 46 air battles between F-4s and MiG-21s, losses amounted to 27 F-4 Phantoms and 20 MiG-21s.<ref>{{cite web|url= http://survincity.com/2013/01/mig-21-against-the-phantom/ |title=MiG-21 against the Phantom | work = Survicinity |access-date=14 November 2014 |url-status=dead |archive-url= https://web.archive.org/web/20141129015210/http://survincity.com/2013/01/mig-21-against-the-phantom/ |archive-date=29 November 2014 }}</ref>{{better source needed|date=October 2022}}

After a million sorties and nearly 1,000 US aircraft losses, [[Operation Rolling Thunder]] came to an end on 1 November 1968.<ref>Michel 1997, p. 149.</ref> A poor air-to-air combat [[loss exchange ratio|loss-exchange ratio]] against the smaller, more agile enemy MiGs during the early part of the war eventually led the US Navy to create their [[Navy Fighter Weapons School]], also known as "[[TOPGUN]]", at [[Naval Air Station Miramar]], [[California]], on 3 March 1969.<ref>Michel 1997, p. 186.</ref> The USAF quickly followed with its own version, called the [[Dissimilar air combat training|Dissimilar Air Combat Training]] (sometimes referred to as [[Red Flag exercise|Red Flag]]) program at [[Nellis Air Force Base]], [[Nevada]]. These two programs employed the subsonic [[Douglas A-4 Skyhawk]] and supersonic [[Northrop F-5|F-5 Tiger II]], as well as the Mach 2.4-capable USAF [[Convair F-106 Delta Dart]], to mimic the MiG-21.<ref>Michel 1997, p. 187.</ref>

The culmination of the air struggle over Vietnam in early 1972 was 10 May, when VPAF aircraft completed 64 sorties, resulting in 15 air battles. The VPAF claimed 7 F-4s were shot down (the U.S. confirmed five F-4s were lost.<ref>{{cite news|url= http://www.acig.org/artman/publish/article_246.shtml|archive-url= https://web.archive.org/web/20040220182211/http://www.acig.org/artman/publish/article_246.shtml|url-status= usurped|archive-date= 20 February 2004|title=Vietnamese Air-to-Air Victories, Part 2|publisher= ACIG |access-date=14 November 2014}}</ref>) The F-4s, in turn, managed to destroy two MiG-21s, three MiG-17s and one MiG-19. On 11 May, two MiG-21s, playing the "bait", brought four F-4s to 2 MiG-21s circling at low altitude. The MiGs quickly stormed the Phantoms and 3 missiles shot down two F-4s. On 13 May, a MiG-21 unit intercepted a group of F-4s and a second pair of MiGs made a missile attack before being hit by two F-4s. On 18 May, VPAF aircraft made 26 sorties, eight of which resulted in combat, downing four F-4s without any VPAF losses.

Over the course of the air war, between 3 April 1965<ref>Anderton 1987, pp. 70–71.</ref> and 8 January 1973, each side would ultimately claim favorable kill ratios. In 1972, the number of air battles between American and Vietnamese planes stood at 201. The VPAF lost 54 MiGs (including 36 MiG-21s and one MiG-21US) and claimed 90 U.S. aircraft shot down, including 74 F-4 fighters and two RF-4C reconnaissance jets (MiG-21s shot down 67 enemy aircraft while MiG-17s shot down 11 and MiG-19s downed another 12{{citation needed|date=May 2020}}).

One MiG-21 was shot down on 21 February 1972 by a USAF F-4 Phantom based at [[Udorn Royal Thai Air Force Base|Udorn RTAFB]], [[Thailand]] and piloted by Major Lodge with 1st Lt Roger Locher as his [[weapon systems officer]] (WSO). This was claimed as the first-ever USAF MiG kill at night, and the first in four years at that time.

Two MiG-21s were claimed shot down by USAF [[Boeing B-52 Stratofortress]] [[tail gunner]]s; the only confirmed air-to-air kills ever made by the B-52. The first aerial victory was scored on 18 December 1972 by tail gunner Staff Sgt Samuel Turner, who was awarded the [[Silver Star]].<ref>[http://www.waymarking.com/waymarks/WM3BYN "The plaque on SSgt Turner's grave."] ''waymarking.com.''

[[File:SolsticeMiGsmall (7633859414).jpg|thumb|VPAF MiG-21 No.4326, which shot down 13 aircraft during the war]]
The biggest threat to North Vietnam during the war had always been the [[Strategic Air Command]]'s B-52 bombers. [[Hanoi]]'s MiG-17 and MiG-19 interceptors could not deal with the B-52s at their flying altitude. In the summer of 1972, the VPAF was directed to train 12 MiG-21 pilots for the specific mission of shooting the B-52 bombers, with two-thirds of the pilots specifically trained in night attacks.<ref>Toperczer #25 2001, p. 61.</ref> On 26 December 1972, just two days after tail gunner Albert Moore downed a MiG-21, a VPAF MiG-21MF (number 5121)<ref>Toperczer #25 2001, p. 66 photo.</ref> from the 921st Fighter Regiment, flown by Major [[Pham Tuan|Phạm Tuân]] over Hanoi, claimed the first aerial combat kill of a B-52.<ref name="Toperczer, p. 66">Toperczer #25 2001, p. 66.</ref> The B-52 had been above Hanoi at over {{convert|30000|ft|m}} when Major Tuân launched two Atoll missiles from 2 kilometres away and claimed to have destroyed one of the bombers flying in the three-plane formation.<ref name="Toperczer, p. 66"/> Other sources argue that the Atoll missiles failed to hit their mark, but as it was disengaging, a B-52 from a three-bomber cell in front of his target took a hit from a [[surface-to-air missile]] (SAM), exploding in mid-air: this may have caused Tuân to think his missiles destroyed the target he had been aiming for.<ref>Michel 2002, pp. 205–6.</ref>

The Vietnamese claimed another kill on 28 December 1972 by a MiG-21 from the 921st FR, this time flown by Vu Xuan Thieu. Thieu is said to have perished in the explosion of a B-52 hit by his own missiles, having approached the target too closely.<ref name="Toperczer, p. 67"/> In this case, the Vietnamese version appears to be erroneous: while one MiG-21 kill was claimed by Phantoms that night (this may have been Thieu's MiG), no B-52s were lost for any reason on the date of the claimed kill.<ref>Michel 2002, p. 213.</ref>

On 3 January 1968, a single MiG-21 pilot, Ha Van Chuc, entered battle with 36 American planes and claimed one F-105 Thunderchief.<ref>{{Cite book | url= https://books.google.com/books?id=h8LvCwAAQBAJ&pg=PT35 | title=MiG-21 Units of the Vietnam War| isbn= 978-1-78200-687-9| last1=Toperczer| first1=István| date=2012-11-20| publisher=Bloomsbury}}</ref>

During the war, the VPAF claimed 103 F-4 Phantoms were shot down by MiG-21s, and that they lost 60 MiG-21s in air combat (54 by Phantoms).<ref>{{cite web |url=http://kienthuc.net.vn/vu-khi/nga-noi-gi-ve-cuoc-dau-mig21-va-f4-o-viet-nam2-287379.html|title=Nga nói gì về cuộc đấu MiG-21 và F-4 ở Việt Nam(2)|date= 27 December 2013|website= Kiến thức |access-date=14 November 2014}}</ref><ref name="Gordon 2008" />

According to Russian data, the VPAF MiG-21s claimed 165 air victories, with the loss of 65 aircraft (including a few by accident or friendly fire) and 16 pilots. The losses of MiG-21 pilots were the lowest of all airplanes.<ref>{{cite web |url=http://old.vko.ru/pictures/2006_26/42_01.jpg |title= Picture |access-date=1 December 2018 | work = VKO |archive-url= https://web.archive.org/web/20140203010754/http://old.vko.ru/pictures/2006_26/42_01.jpg |archive-date= 3 February 2014 |url-status=dead}}</ref>

===Arab–Israeli conflicts===
[[File:MirageIIIShotDownByMiG-21.jpg|thumb|Israeli [[Dassault Mirage III|Mirage III]] shot down by an Egyptian MiG-21 during the [[Yom Kippur War]]]]
The MiG-21 was also used extensively in Middle Eastern conflicts of the 1960s, 1970s and 1980s by the [[Egyptian Air Force]], [[Syrian Air Force]] and [[Iraqi Air Force]]. The MiG-21 first encountered Israeli [[Mirage III]]CJs on 14 November 1964, but it was not until 14 July 1966 that the first MiG-21 was shot down. Another six Syrian MiG-21s were shot down by Israeli Mirages on 7 April 1967. MiG-21s also faced [[McDonnell Douglas F-4 Phantom II]]s and [[Douglas A-4 Skyhawk]]s, but were later outclassed by the more modern [[McDonnell Douglas F-15 Eagle]] and [[General Dynamics F-16 Fighting Falcon]], both acquired by Israel starting in the mid-1970s.{{citation needed|date=February 2023}} During this period, Syrian pilots flying MiG-21s also independently discovered the [[Cobra maneuver]], which became a standard defensive maneuver under the name "zero speed maneuver" (Syrian: مناورة السرعة صفر).<ref>{{Cite web|url=https://theaviationgeekclub.com/the-unknown-story-of-the-syrian-mig-21-pilot-who-developed-the-cobra-manoeuvre-i-e-pugachev-wasnt-the-first-to-perform-the-cobra/|title=The Unknown Story of the Syrian MiG-21 Pilot who Developed the Cobra Manoeuvre: i.e. Pugachev Wasn’t the First to Perform the Cobra|first=Tom|last=Cooper|date=7 August 2019|website=The Aviation Geek Club}}</ref>

During the opening attacks of the 1967 [[Six-Day War]], the [[Israeli Air Force]] (IAF) struck Arab air forces in four attack waves. In the first wave, Israeli pilots claimed to have destroyed eight Egyptian aircraft in air-to-air combat, of which seven were MiG-21s; Egypt claimed five kills scored by MiG-21PFs.<ref>[http://www.acig.info/CMS/index.php?option=com_content&task=view&id=185&Itemid=47 "Egyptian Air-to-Air Victories since 1948"]. ACIG. Retrieved: 25 August 2013.</ref> During the second wave, Israel claimed four more MiG-21s downed in air-to-air combat, with the third wave resulting claimed air victories over two Syrian and one Iraqi MiG-21. The fourth wave destroyed many more Syrian MiG-21s on the ground. Overall, Egypt lost around 100 out of about 110 MiG-21s they had, almost all on the ground; Syria lost 35 of its 60 MiG-21F-13s and MiG-21PFs in the air and on the ground.<ref name="Gordon 2008" />

Between the end of the Six-Day War and the start of the [[War of Attrition]], IAF Mirage fighters scored six confirmed kills of Egyptian MiG-21s, and Egyptian MiG-21s scored two confirmed and three probable kills against Israeli aircraft. Between the end of the Six-Day War to the end of the War of Attrition, Israel claimed a total of 25 destroyed Syrian MiG-21s; the Syrians claimed three confirmed and four probable kills of Israel aircraft, although Israel denied these.<ref name="Gordon 2008" />

High losses to Israeli aircraft and continuous bombing during the War of Attrition caused Egypt to ask the Soviet Union for help. In March 1970, Soviet pilots and SAM crews arrived with their equipment. On 13 April, during the air battle over the Red Sea coast, the Soviet MiG-21MFs, according to some data, shot down two Israeli F-4 fighters<ref>Окороков А. В.

After that, several more successful intercepts were carried out by Soviet pilots and another Israeli A-4 was shot down on 25 June.<ref name=safar />

In response, Israel planned an ambush, calling it [[Operation Rimon 20]]. On 30 July, Israeli F-4s lured Soviet MiG-21s into an area where they were ambushed by Israeli Mirages. [[Asher Snir]], flying a Mirage IIICJ, destroyed a Soviet MiG-21; [[Avihu Ben-Nun]] and [[Aviam Sela]], both piloting F-4Es, each got a kill, and an unidentified pilot in another Mirage scored a fourth kill against a Soviet-flown MiG-21; the IAF suffered only a damaged Mirage. Three Soviet pilots were killed and the [[Soviet Union]] was alarmed by the losses. Yet though it was a [[morale]]-boosting achievement, ''Rimon 20'' did not change the course of the war. After the operation, other IAF aircraft were lost to Soviet MiG-21s and SAMs. A week later, on 7 August, the Soviets responded by deploying more aircraft to Egypt and luring Israeli fighter jets into an ambush of their own, "Operation Kavkaz", downing two Israeli Mirage IIICJs.<ref>Sachar, Howard: ''Israel and Europe: An Appraisal in History'', p. 171-172</ref> In all, during March and August 1970, Soviet MiG-21 pilots and SAM crews destroyed 21 Israeli aircraft (eight by [[SA-3]] missile systems and 13 by MiG-21s) at a cost of 5 MiG-21s shot down by the IAF, helping to convince the Israelis to sign a [[ceasefire]].<ref>Зенитные ракетные войска в войнах во Вьетнаме и на Ближнем Востоке (в период 1965–1973 гг.).

In September 1973, a large air battle erupted between Syria and Israel; Israel claimed a total of 12 Syrian MiG-21s destroyed, while Syria claimed eight kills scored by MiG-21s and admitted five losses.{{citation needed|date=December 2021}}

During the [[Yom Kippur War]], Israel claimed 73 kills against Egyptian MiG-21s (65 confirmed). Egypt claimed 27 confirmed kills and eight probables against Israeli aircraft by its MiG-21s.<ref name="Gordon 2008" /> However, according to most Israeli sources, these were exaggerated claims, as Israeli air-to-air combat losses for the entire war did not exceed fifteen.<ref name=pollack124>Pollack 2004, p. 124.</ref><ref>Herzog 1975, p. 259.</ref>

On the Syrian front, 6 October 1973 saw a flight of Syrian MiG-21MFs shoot down an Israeli A-4E and Mirage IIICJ, losing three of their own to Israeli [[IAI Nesher]]s. On 7 October, Syrian MiG-21MFs downed two Israeli F-4Es, three Mirage IIICJs and an A-4E while losing two of their MiGs to Neshers and one to an F-4E, as well as two to friendly SAM fire. Iraqi MiG-21PFs also operated on this front, and on that same day destroyed two A-4Es while losing one MiG. On 8 October 1973, Syrian MiG-21PFMs downed three F-4Es, but six of their MiG-21s were lost. By the end of the war, Syrian MiG-21s claimed a total of 30 confirmed kills against Israeli aircraft; 29 MiG-21s were claimed (26 confirmed) as destroyed by the [[Israel Defense Forces|IDF]].<ref name="Gordon 2008" />

Later on 26 April 1974, an unusual occurrence involving [[Pakistanis|Pakistani]] fighter pilot [[Sattar Alvi|Flight Lieutenant Sattar Alvi]] took place while he was on deputation to the No. 67A Squadron of the Syrian Air Force. Alvi, flying a Syrian MiG-21F-13 (Serial No. 1863) out of Syria's [[Al-Dumayr Military Airport|Al-Dumayr Air Base]] with a fellow [[Pakistan Air Force|PAF]] pilot, was on aerial patrol near the [[Golan Heights]] when he spotted two Israeli Mirage-IIICJs intruding in Syrian airspace. According to modern Pakistani sources, Alvi and his flight leader engaged them, and after a brief dogfight, shot down one of the Mirages, flown by Captain M. Lutz. The Israeli pilot later succumbed to wounds he sustained during ejection.<ref>{{cite web|url=http://tribune.com.pk/story/855837/50-years-on-memories-of-the-1973-arab-israeli-conflict|title=50 years on: Memories of the 1973 Arab-Israeli Conflict|date=19 March 2015|website=The Express Tribune}}</ref><ref>{{cite tweet|number=1519042488480059392|user=DGPR_PAF|title=26 Apr 1974 holds significant importance for Pakistan Air Force.

Between the end of the Yom Kippur War and the start of the [[1982 Lebanon War]], Israel received modern F-15s and F-16s which were far superior to the old Syrian MiG-21MFs. According to the IDF, these new aircraft shot down 24 Syrian MiG-21s over this period, though Syria did claim five IAF kills by MiG-21s armed with outdated [[K-13 (missile)|K-13 missiles]]; Israel denied that it had suffered any losses.<ref name="Gordon 2008" />

The 1982 Lebanon War began on 6 June 1982, and during the conflict the IAF claimed to have destroyed about 45 Syrian MiG-21MFs.

===Syrian civil war===
{{See also|List of aviation shootdowns and accidents during the Syrian Civil War}}

Beginning in July 2012, at which point the [[Syrian civil war]] had lasted a year without aerial action, the [[Syrian Air Force]] started operations against Syrian insurgents. MiG-21s were among the first combat-ready aircraft used in bombings, rocket attacks and [[Strafing|strafing runs]], with numerous videos showing the attacks.<ref>{{cite web|url=http://theaviationist.com/2013/10/31/bomb-on-you/|title=The Aviationist " [Video] This is what being in the trajectory of a bomb dropped by a Syrian attack plane looks like|website=The Aviationist|access-date=14 November 2014|date=2013-10-31}}</ref>

The rebels had access to [[heavy machine gun]]s, different anti-aircraft guns and Russian and Chinese [[MANPADS]], up to modern designs such as the [[FN-6]]. The first loss of a MiG-21 during the Syrian civil war was recorded on 30 August 2012. The MiG, registration number 2271, was likely downed by heavy machine gun fire on takeoff or landing at [[Abu al-Duhur Military Airbase]], [[Siege of Abu al-Duhur Airbase|under siege by rebels]].<ref>{{cite web|url=http://theboresight.blogspot.fr/?view=classic|title=The Boresight|access-date=14 November 2014}}</ref>{{failed verification|date=December 2021}} A few days later, on 4 September 2012, another MiG-21 (registration number 2280) was shot down in similar circumstances at the same base, also likely on takeoff or landing by rebels using by [[KPV]] 14.5&nbsp;mm machine guns; the downing was recorded on video.<ref>{{cite web|url=http://brown-moses.blogspot.it/2012/09/mig-21-shot-down-in-idlib.html|title=Brown Moses Blog|author=Brown Moses|access-date=14 November 2014|date=2012-09-04}}</ref>

On 10 November 2014, Syrian Air Force MiG-21bis number 2204 was shot down, and its pilot killed, by rebels either using a MANPADS or antiaircraft guns, near the town of [[Sabburah]], 45&nbsp;km east of [[Hama]] Airbase where it was likely based. Video and photo evidence of the crash site later emerged.{{citation needed|date=October 2020}}

Four months after a MiG-23 was shot down and during which time the Syrian Air Force suffered no losses from enemy fire, one of its MiG-21s was shot down on 12 March 2016 by the [[Jaysh al-Nasr]] faction over [[Hama Governorate|Hama]] near [[Kafr Nabudah]]. While the [[Syrian Observatory for Human Rights]], as suggested by video evidence, reported that the warplane had been downed by two MANPADS, Jaysh al-Nasr militants claimed to have shot it down with anti-aircraft guns.<ref>{{cite web|url=https://news.yahoo.com/syria-rebels-shot-down-warplane-170059577.html|title=Rebels shoot down Syrian warplane|date=12 March 2016 |agency=Reuters}}</ref> The pilot appeared to have bailed out of the stricken MiG, but died from ground fire or other causes.{{citation needed|date=October 2020}}

On 4 March 2017, a Syrian MiG-21bis from No. 679 squadron, operating out of Hama Airbase and piloted by Col. Mohammad Sawfan, was shot down by [[Ahrar al-Sham]] rebels, crashing in [[Turkey|Turkish]] territory near the border. Col. Sawfan successfully ejected but was arrested and taken to a hospital in [[Antakya]], Turkey. A recording between the pilot and ground controller clearly showed Sawfan's disorientation due to a malfunctioning compass, followed by a failure of the entire navigation system. He could not find his way back to base as ordered and inadvertently flew within range of rebel anti-aircraft guns.{{citation needed|date=October 2020}} After being suspended for a number of years, Sawfan was allowed to return to service.

===Libyan–Egyptian War===
Egypt received American [[AIM-9 Sidewinder|Sidewinder]] missiles, fitting them to their MiG-21s and successfully using them in combat against Libyan Mirages and MiG-23s during the brief [[Egyptian–Libyan War]] of July 1977.

====Libyan Civil War (2014–2020)====
In the [[Second Libyan Civil War (2014–present)|Second Libyan Civil War (2014–2020)]], the [[Libyan National Army]], under the command of [[Khalifa Haftar]] is loyal to the legislative body in [[Tobruk]], which is the [[House of Representatives (Libya)|Libyan House of Representatives]], internationally recognised until October 2015. It fights against the now internationally recognized [[Government of National Accord]] and the [[Shura Council of Benghazi Revolutionaries]] as well as [[Islamic State in Libya]] which are common enemies for both the [[Government of National Accord]] and the [[Libyan National Army]]. Both the [[Libyan National Army]] and the [[Government of National Accord]] field small airforces.
As such, a number of former Libyan Arab Air Force (LARAF) MiG-21s were returned to service with the Tobruk-based [[Libyan National Army]], thanks to spare parts and technical assistance from Egypt and Russia, while a number of former Egyptian Air Force MiG-21s were pressed into service as well.{{citation needed|date=November 2020}}

===Horn of Africa===
During the [[Ogaden War]] of 1977–78, [[Ethiopian Air Force]] F-5As engaged [[Somali Air Force]] MiG-21MFs in combat on several occasions. In one lopsided incident, two F-5As piloted by Israeli advisers or mercenaries engaged four MiG-21MFs. The MiGs were handled incompetently by the Somali pilots, and the F-5As destroyed two while the surviving pilots collided with each other avoiding an [[AIM-9]].<ref name="Gordon 2008" />{{page needed|date=December 2021}}

Ethiopia claimed to have shot down 10 Somali MiG-21MFs; while Somalia also claimed to have destroyed several Ethiopian MiG-21MFs, three F-5Es, one [[English Electric Canberra|Canberra]] bomber and three [[Douglas DC-3]]s.<ref name="Gordon 2008" /> Ethiopian MiG-21s were deployed largely in the ground attack role, and proved instrumental during the final offensive against Somali ground forces.<ref name="Gordon 2008" />{{page needed|date=December 2021}}

Ethiopian pilots who had flown both the F-5E and the MiG-21 and received training in both the US and the USSR considered the F-5 to be the superior fighter because of its manoeuvrability at low to medium speeds, its superior instrumentation and the fact that it was far easier to fly, allowing the pilot to focus on combat rather than controlling his airplane.<ref name="Wings">Cooper, Tom., "Wings over Ogaden, 2015, ch. 3</ref> This effect was enhanced by the poor quality of pilot training provided by the Soviets, which provided limited flight time and focussed exclusively on taking off and landing, with no practical training in air combat.<ref name="Wings"/><ref name="EEW">Cooper, Tom & Fontanellaz, Adrian, "Ethiopian-Eritrean Wars Volume 1, 2018, ch. 4</ref>

===Angola===
During [[Angola]]'s [[Angolan Civil War|long-running civil war]], MiG-21s of the [[Cuban Air Force]] were frequently deployed to attack ground targets manned by rebel forces or engage [[South African Air Force]] [[Mirage F1]]s conducting cross-border strikes. Most MiG-21 losses over Angola were attributed to accurate ground fire, such as an example downed by [[UNITA|National Union for the Total Independence of Angola]] (UNITA) insurgents near [[Luena, Moxico Province|Luena]] with an American [[FIM-92 Stinger]].<ref>{{cite web|url=http://havanaluanda.wordpress.com/2013/11/13/prisioneros-a-color/|title=Prisioneros a color|website=Havanaluanda|access-date=14 November 2014|date=2013-11-14}}</ref>

Despite extensive losses to [[man-portable air-defense systems]], MiG-21s were instrumental during the [[Battle of Cuito Cuanavale]]; Cuban pilots became accustomed to flying up to three sorties a day. Both the MiG-21MF and the MiG-21bis were deployed almost exclusively in the [[Fighter-bomber|fighter/bomber]] role. As interceptors, they were somewhat unsuccessful due to their inability to detect low-flying South African aircraft.<ref name="Angola">{{cite web|url=http://www.acig.org/artman/publish/article_184.shtml|archive-url=https://web.archive.org/web/20040519054722/http://www.acig.org/artman/publish/article_184.shtml|url-status=usurped|archive-date=19 May 2004|title=Angola: Claims and Reality about SAAF Losses|access-date=14 November 2014}}</ref> On 6 November 1981, a Mirage F1CZ achieved South Africa's first confirmed air-to-air kill since the [[Korean War]] when it destroyed Cuban Lieutenant Danacio Valdez's MiG-21MF with 30mm cannon fire.<ref name="Transport">{{cite web|url=http://www.sa-transport.co.za/aircraft/mirage_f1_saaf_service.html|title=Mirage F1 in SAAF Service|access-date=14 November 2014}}</ref> On 5 October 1982, Mirages escorting an [[English Electric Canberra]] on routine reconnaissance over [[Cahama]] were engaged by at least two MiG-21bis. A South African radar operator picked up the attacking MiGs and was able to alert the Mirage pilots in advance, instructing them to change course immediately. As they jettisoned their auxiliary tanks, however, they were pinpointed by the Cubans, who opened pursuit. In a vicious [[dogfight]], SAAF Major John Rankin closed range and maneuvered into the MiGs' rear cones. From there, one of his two [[R.550 Magic]] missiles impacted directly behind the lead MiG and forced it down. The second aircraft, piloted by Lieutenant Raciel Marrero Rodriguez, could not detect the Mirage's proximity until it had entered his turn radius and was perforated by Rankin's autocannon. This damaged MiG-21 landed safely at [[Lubango]].<ref name="Transport"/>

Contacts between MiG-21s and SAAF Mirage F1s or [[Mirage III]]s became increasingly common throughout the 1980s. Between 1984 and 1988, thirteen MiG-21s were lost over Angola.<ref>{{cite web|url=http://www.mercenary-wars.net/angola/angola-86-89/russian-downed-pilots.html|title=Angolan and Soviet Pilots|access-date=14 November 2014|archive-date=4 May 2014|archive-url=https://web.archive.org/web/20140504001623/http://www.mercenary-wars.net/angola/angola-86-89/russian-downed-pilots.html|url-status=dead}}</ref> On 9 August 1984, a particularly catastrophic accident occurred when the 9th Fighter Training Squadrons and the 12th Fighter Squadrons of the Cuban Air Force attempted to carry out an exercise in poor weather.

[[Socialist Federal Republic of Yugoslavia|Yugoslavia]] purchased its first batch of MiG-21s in 1962 from the [[Soviet Union]]. From 1962 to the early 1980s, Yugoslavia purchased 261 MiG-21s, of ten different variants.

During the early stages of the 1990s' [[Yugoslav wars]], the [[Yugoslav People's Army|Yugoslav military]] used MiG-21s in a ground-attack role, while Croatian and Slovene forces did not yet have air forces at that point in the conflict. Aircraft from air bases in Slovenia, Croatia, and Bosnia and Herzegovina were relocated to air bases in Serbia.

Beginning in 1993, Russia did not offer spare parts for the MiG-23 and MiG-29 for the RoAF. Initially, this was the context for the modernization of the Romanian MiG-21s with [[Elbit Systems]], and because it was easier to maintain these fighter jets. In 1995–2002, a total of 111 MiG-21s were modernized, of which 71 were M and MF/MF-75 variants modernized under the LanceR A designation (for ground attack), 14 were UM variant as LanceR B designation (trainer), and another 26 MF/MF-75 variant were modernized under LanceR C designation (air superiority).<ref name="aa"/> Today, only 36 LanceRs are operational for the RoAF.

The [[Bulgarian Air Force]] received a total of 224 MiG-21 aircraft. From September 1963 the 19th Fighter Regiment of the Air Force received 12 MiG-21F-13s. Later some of these aircraft were converted for reconnaissance as MiG-21F-13Rs, which were submitted to the 26th Reconnaissance Regiment in 1988. In January 1965 the 18th Fighter Regiment received a squadron of 12 MiG-21PFs, some of which also were converted and used as reconnaissance aircraft (MiG-oboznachevnieto 21PFR). The 26 Regiment reconnaissance aircraft from this squadron were removed from service in 1991, the 15 Fighter Regiment in 1965 received another 12 MiG-21PF fighters and in 1977–1978 operated another 36 refurbished aircraft. This unit received two more aircraft in 1984 and operated them until 1992.

[[File:Bulgarian Air Force Mikoyan-Gurevich MiG-21bis Lofting-1.jpg|thumb|upright|MiG-21bis [[Bulgarian Air Force]]]]
For reconnaissance, a regiment received 26 specialized reconnaissance MiG-21Rs in 1962, and in 1969–1970, 19 Fighter Aviation Regiment received 15 MiG-21m aircraft, which operated in 21 Fighter Aviation Regiment and were removed from active service in 1990. An additional 12 MiG-21MF fighters were received in 1974–1975, with a reconnaissance version of the MiG-21MFR provided to the 26th Reconnaissance Regiment and used until 2000, when removed from active service.

From 1983 to 1990, the Bulgaria Air Force received 72 MiG-21bis. Of these, 30 (six new and renovated) are under option with ACS and provided to the 19th Fighter Regiment; the rest are equipped with the "Lazur". This batch was taken out of service in 2000.

Besides fighters, the Air Force has received 39 MiG-21U trainers (one in 1966), five MiG-21US in 1969–1970 and 27 MiG-21UM (new) during 1974–1980, another six refurbished ex-Soviet examples in 1990. In 1982, three MiG-21UM trainers were sold to Cambodia and in 1994 another 10 examples. MiG-21UMs were also sold to India. Other training aircraft were removed from active service in 2000. A total of 38 aircraft were lost in the period 1963–2000.

The last flight of a [[Bulgarian Air Force]] MiG-21 took off from [[Graf Ignatievo Air Base]] on 31 December 2015.
