Direct proof of use
The MiG-21 is documented in Syrian government service during the Syrian Civil War through Syrian Arab Air Force campaign reporting, airframe-loss records, and a specific March 2016 shootdown. Bellingcat reported that after the Syrian Arab Air Force became actively involved in suppressing the rebellion in late July 2012, MiG-21s, MiG-23BNs, Su-22s, and some Su-24s joined the expanding air campaign in the following months.
GPPi's Syrian Air Force analysis found that the aging MiG-21 fleet increasingly fell out of use as the war progressed, but that at least four MiG-21 jets remained visually confirmed in service at Hama Air Base and accounted for a small share of combat sorties after 2016. The Aviationist documented one Syrian Arab Air Force MiG-21 from Hama shot down over Kafr Nabudah on 12 March 2016, while The Washington Institute separately described opposition claims and competing accounts over the same regime MiG-21 incident.

Timeline
The public record places the MiG-21 in the Syrian government air campaign after fixed-wing air operations intensified in 2012. Bellingcat's reconstruction says the months after the late-July 2012 escalation brought MiG-21s into the broader sortie pattern alongside other Syrian Arab Air Force fighter-bombers.
The airframe record then becomes clearest through losses, base pressure, and later operational estimates. Oryx reported that four inoperable MiG-21s were captured at Abu ad-Duhor airbase when the base fell in September 2015, while GPPi later assessed that four MiG-21s were still in service at Hama and that another 28 had been destroyed in combat by late 2020.

Narrative
In this conflict, the MiG-21 appears as an aging Syrian Arab Air Force fighter retained for limited combat use rather than as a newly supplied system. Bellingcat described most Syrian MiG-21s as early-1970s aircraft that were near the end of their service lives, but still part of the fighter-bomber fleet drawn into the war as the government air campaign expanded beyond L-39 sorties.
GPPi's later analysis narrows the aircraft's mature-war role. It says Syrian Air Force flight data showed older jets falling out of use, with the MiG-21 considered effectively obsolete at the start of the war, some airframes repurposed for remote-controlled suicide-jet work, and late-2020 satellite imagery showing many discarded MiG-21s around Syrian airbases. The same analysis nevertheless found a small number still active at Hama, accounting for no more than two percent of combat sorties after 2016.
Opposition possession should be separated from operational use. Oryx reported that four MiG-21s captured at Abu ad-Duhor in 2015 were inoperable and had been unable to evacuate to Hama; that evidence documents captured materiel, not rebel combat use. The clearest named combat incident remains the 12 March 2016 Kafr Nabudah shootdown of a Hama-based Syrian Arab Air Force MiG-21, with sources differing over whether antiaircraft guns or a MANPADS caused the loss.
