Ukraine is now operating MiG-29s from Azerbaijan: repairs, Fulcrum performance, costs, and strategic impact in the war.
The Ukrainian air offensive has been bolstered by an unexpected addition: MiG-29 Fulcrums formerly belonging to Azerbaijan are now in service with the Ukrainian Air Force. These aircraft were undergoing repairs at the Lviv factory when Russia invaded in February 2022, leaving them grounded. With the conflict having severely reduced available personnel, every aircraft counts. This transfer or reappropriation slightly improves Kiev’s tactical capabilities. It raises technical, logistical, financial, and strategic questions.
The context of the transfer
Before the Russian invasion in 2022, three MiG-29s from the Azerbaijani Air Force were undergoing repairs and modernization at the Lviv Aircraft Repair Plant. During the Russian attack on this site, some hangars were destroyed, but at least one of the Fulcrums survived. Recent photos show a MiG-29 still sporting Azerbaijani camouflage, armed with R-27 (medium-range) and R-73 (short-range) air-to-air missiles, with Ukrainian insignia. It is unclear whether this transfer was formal (donation or sale) or whether it was done pragmatically, in the context of war. According to several media sources, the number of aircraft involved could be as high as three MiG-29s. These aircraft were originally sold by Ukraine to Azerbaijan between 2006 and 2009 (≈15 units).
The technical performance of the MiG-29 in this context
The MiG-29 Fulcrum is a 4th generation Soviet supersonic fighter. It can reach a maximum speed of approximately 2,400 km/h (Mach ~2.25) in ideal conditions, with a range of around 700-800 km depending on the mission. The Ukrainian aircraft have been upgraded to MU-1/MU-2 standards, improving avionics, radar, and the ability to use modern weapons, including Western precision-guided missiles and bombs. Fulcrums are effective in interception, local superiority, and defending the skies against Russian drones and bombers. Their ability to use R-27 and R-73 missiles makes them useful for air-to-air missions. They are durable, relatively easy to maintain, and spare parts are available in Ukrainian facilities.
Estimated costs and logistical constraints
Returning Azerbaijani MiG-29s to service requires investment, but less than for new fighters. The cost of a used aircraft includes structural repair, electronics upgrades, test certification, and integration of modern weapons. There are no reliable public figures for these MiG-29s, but comparable refurbishment costs can run into millions of dollars per aircraft—perhaps $2 million to $10 million depending on the extent of the work. Logistical support requires spare parts, maintenance experts, and suitable workshops. The Lviv factory has proven capacity for this type of work, which reduces turnaround times. Nevertheless, some MiG-29s may have suffered damage (during attacks) or may be missing specific components, complicating rapid return to service. The cost of crew training, simulators, and doctrine of use also weighs heavily.
The impact on the war and the Ukrainian fleet
The Ukrainian MiG-29 fleet has suffered heavy losses since 2022, with more than 30 Fulcrums destroyed or damaged according to tracking sources. Each aircraft recovered reduces the effect of attrition. These new arrivals strengthen local air defense, interception missions, and air superiority patrols in Ukrainian skies. They provide coverage in certain sectors where more modern aircraft (F-16s, etc.) are not yet available or cannot operate in sufficient numbers. In addition, the deployment of Azerbaijani Fulcrums highlights implicit support from other countries, or at least greater tolerance for unofficial transfers. This may attract diplomatic reprisals or political pressure. On the ground, this means that Kiev can maintain more constant air pressure, better distribute its patrols, and delay Russian advances. But the effect remains modest on a global scale, as long as the numbers remain low and overall air superiority does not change radically.
Limitations, technical challenges, and strategic implications
Although these MiG-29s provide useful reinforcement, their limitations are clear. They do not offer the stealth or power of modern Western fighters. Their avionics, radar, and electronic warfare capabilities fall short of the latest standards. The limited number of aircraft (one to three, according to reports) constrains their operational impact. In addition, prolonged maintenance in wartime conditions weighs on availability. The obsolescence of certain components (sensors, engine parts) makes their maintenance more difficult. Strategically, this transfer symbolizes a rise in unconventional support for Ukraine: countries or external sources are accepting the use of foreign-made aircraft without clear announcements. It also shows that Ukraine is relying heavily on pragmatic adaptations, using what is available to maintain air pressure. In the long term, the priority remains to obtain modern aircraft, but the Azerbaijani Fulcrums provide valuable tactical respite.
