Ukraine is remaking its air force on NATO’s model, down to the way its squadrons are organized and the aircraft they fly. The reforms are planned to be completed by 2035 and include modernizing its F-16s while pursuing the Swedish Gripen jets, Air Force Spokesperson Yurii Ihnat says, per Tse Baza.

Ukraine’s fighters are working hard against Russia’s air war, and in the previous month alone the Air Force faced around 3,500 jet-powered targets, with F-16s heavily used to intercept Russian drones. The new reform is meant to build an air force that can be sustained over the long term and can contest Russian jets and glide bombs, not only survive the next wave.

Wings and universal air bases

The central change, Ihnat said, is a move to the “wing” units that NATO air forces use. The first steps have already been taken: Ukraine has set up the 107th F-16 wing, which now has its own Facebook page and may publish material about its work.

Ukraine also plans to build universal air bases on the operational airfields it has used through the full-scale war. In the future, Ihnat says, those bases should be able to receive and service different models of combat aircraft, as NATO does.

A worn fleet, and the jets Ukraine wants next

Currently, the F-16s Ukraine flies are older Block 15 jets, used by other countries before they arrived, and intensive combat has left them in need of repairs, service life restoration, and upgrades.

Ukrainian officials discussed modernization with the American manufacturer Lockheed Martin, while Kyiv would prefer the newer Block 70/72 version, which Ihnat says would let its pilots stand up more confidently to Russia’s Su-35 fighters.

Keeping the current fleet flying has been hard: fewer than half of Ukraine’s F-16s may be operational, held back by slow maintenance abroad.

At the same time, Lockheed Martin and Kyiv are discussing a special F-16 variant for Ukraine, with a modern AESA radar, longer range, and a wider choice of weapons, though no firm deal exists yet.

Ukraine is also counting on Swedish Gripen fighters. Ihnat says Ukrainian pilots are drawn to them for their lower operating costs and simpler maintenance, with the country likely to receive older C/D models first, before the newer Gripen E that Saab is developing.

Ukrainian pilots have already begun their training on the Gripen, a jet seen as a counter to the Russian aircraft dropping guided glide bombs on the front, though delivery timing depends on further agreements.

When Ukrainian President Volodymyr Zelenskyy met a Lockheed Martin team led by Orlando Sanchez Jr., head of its aeronautics division, in Kyiv on 19 October, the talk was of Patriot interceptors and of repairing the Ukrainian air force's small but growing fleet of ex-European F-16 fighters inside the country. Lockheed designed the F-16 and still builds it.

But the Lockheed officials may have had other things on their minds. They gave Zelenskyy a scale model of a new and improved F-16 variant in Ukrainian livery, according to a photo posted by the MilitaryNewsUA account.

In late September, Ukraine's air force commander, Lt. Gen. Anatolii Kryvonozhko, and Lockheed discussed a possible move to newer F-16s. Now we have a clearer idea what those F-16s might look like—and what they might be capable of. The model Lockheed officials gave to Zelenskyy appears to be based on the Block 70/72 version of the classic supersonic fighter that Lockheed manufactures at its factory in Greenville, South Carolina.

It's a world-class jet. But a pricey batch of factory-fresh Block 70/72s isn't actually at the top of the Ukrainian air force's wish list. Not as long as the air force's existing warplanes lack munitions.

The Block 70/72 boasts a better radar, more fuel capacity, and a tougher airframe compared to older F-16 models, which have been flying since the late 1970s. The F-16 is still one of the most numerous fighter types in US Air Force service. Surplus 1980s-vintage F-16s from Denmark and the Netherlands make up the bulk of the Ukrainian air force's front-line fleet. Norway's six are still being refurbished, and Belgium's are coming.

Whether Ukraine ever gets new F-16s is anyone's guess. Kyiv would need to pay around $100 million per copy, or find an ally to finance the purchase. Either could be a heavy lift. And to be sure, Ukraine has options as it rebuilds its battered air force. Sweden is donating 16 older Saab Gripens, the first due early next year, and Kyiv plans to buy 20 newer ones. Kyiv has negotiated to buy 16 Dassault Rafales from France, which may not arrive until 2028. Belgium has promised as many as 53 older F-16s, the last of them perhaps not until 2029.

Welcome jets

But new Block 70/72 F-16s would be welcome. The Block 70/72 builds on what already makes the F-16 great: its agility, flexibility, reliability, excellent electronic warfare systems, and compatibility with a wide array of munitions.

Where the Block 15 Mid Life Update F-16s Ukraine currently flies have the older analog AN/APG-66(V2) radar, the Block 70/72 has a digital APG-83 active electronically scanned array radar. It can also carry overwing conformal fuel tanks for extra range.

Perhaps most exciting for the Ukrainian air force, a newly made Block 70/72 is good for 12,000 hours of flight: enough for about 30 years at 400 flying hours a year. An aging Block 15 has a structural life of about 8,000 hours, and Ukraine's jets fly hard. Zelenskyy has said about half of them spend long stretches abroad for repairs, many at Sabena Aerospace Engineering in Belgium, a process that can take months.

Newer F-16s require less maintenance. They can fly and fight more often. In that sense, 50 Block 70/72s are worth more than 50 Block 15s.

But the availability of airframes isn't the biggest problem in the 107th Aviation Wing, the Ukrainian air force's sole F-16 unit. The wing is desperately low on air-to-air missiles. Its pilots often resort to gunning down Russian drones and cruise missiles with the F-16's built-in 20-mm cannon—a risky tactic given how close a fighter must get to its target to make use of its gun.

While a few billion dollars' worth of fresh F-16s could keep the 107th Aviation Wing in fighting shape for decades to come, fresh airframes aren't actually the most urgent priority. Given a choice between getting new F-16s or getting substantial supplies of missiles for its old F-16s, the wing would surely opt for the latter.

Belgium’s 10 F-16s bring Ukraine’s promised fleet to about 100 jets. Fewer than 40 are flying, as Russia’s jet drones run them ragged

Ukraine has received more than 50,000 rounds of 20-mm ammunition from Denmark for the onboard cannons of its F-16 fighter jets, with Ukrainian pilots already using the rounds to intercept Russian jet-powered Geran attack drones, Ukraine’s Defense Ministry said.

The accelerated delivery addresses a key need in Ukraine’s air defense as Russia increasingly deploys faster jet-powered drones that challenge conventional interceptors. Ukraine has also relied on F-16 cannons when stocks of air-to-air missiles are limited, making ammunition supplies important to keeping the aircraft effective against incoming aerial threats.

Denmark responds to ammunition request

The Defense Ministry thanked Denmark for responding quickly to Ukraine’s request for additional ammunition, saying the delivery directly strengthens the country’s air defenses and helps protect civilians from Russian aerial attacks.

The delivery follows a broader effort by Ukraine’s European partners to replenish F-16 cannon ammunition. On October 2, it was reported that Spain, Belgium, and Poland were also sending 20-mm rounds for Ukrainian F-16s to counter Russia’s jet-powered drones.

Belgium is also expanding its support for Ukraine’s F-16 fleet. On 16 October, Belgian Prime Minister Bart De Wever pledged to deliver 10 F-16s by the end of 2026, up from three previously planned, and discussed supplying additional ammunition, including 20-mm rounds produced by Belgian defense company FN Herstal.

Jet-powered drones pose a growing challenge

Russia’s faster attack drones are harder to intercept than older, propeller-driven Shahed-type models. Their speed gives air defenders less time to respond and makes them more difficult for many interceptor drones and conventional short-range weapons to catch.

Ukraine’s air-to-air missile shortages have also increased the importance of F-16 cannon ammunition. Ukrainian pilots have sometimes relied on their aircraft’s built-in 20-mm cannon when air-to-air missiles are scarce.

The threat from jet-powered drones is growing. Ukrainian President Volodymyr Zelenskyy said in late September that Ukraine was intercepting about 55% of Russia’s jet-powered drones, compared with more than 90% of older models.

Denmark’s ammunition delivery gives Ukrainian F-16 pilots more rounds to engage these faster targets, as Ukraine works to strengthen its defenses against Russia’s expanding drone campaign.

Two Romanian F-16s shot down two jet-powered Russian Geran attack drones over Romania’s territorial waters near Sulina on the evening of 17 October, Romania’s Defense Ministry said. The ministry released cockpit images of the mission the next day, as NATO allies prepare to discuss Black Sea security at a special session Romania requested.

This comes as Moscow continues its air attacks on Ukraine, while the US is trying to make deals with Russia over its diesel and lift sanctions. Russia keeps striking Ukraine’s energy system and cities, while its drones and suspected saboteurs keep turning up inside NATO, from tankers hit off Romania to a foiled arson attempt at a Starlink site in Lithuania.

Down within minutes

The F-16s took off from the 86th Air Base at Borcea at 17:43 after radar detected a group of air targets about 120 km east of Zmiinyi (Snake) Island, flying southwest, Ukrainian military outlet Militarnyi reported, citing the ministry. The first drone entered Romanian airspace at 17:59 and was shot down at 18:01 southeast of Sulina. The second entered at 18:01 and was downed at 18:05 east of Sulina.

Both were jet-powered attack drones of the Geran family, the ministry said. The Geran is Russia’s version of the Iranian-designed Shahed. When first detected, the drones were about 65 km from the coast of Russian-occupied Crimea and 140 km from the Ukrainian-held shore, and their southwest course may point to Russian origin, Militarnyi calculated.

The ministry posted the cockpit images on 18 October, showing a missile launch and a fireball over the sea. “Targets spotted, identified, engaged and neutralized!” it wrote.

Allies to meet on the Black Sea

A special session of the North Atlantic Council, NATO’s top decision-making body, will discuss defense and deterrence in the Black Sea on 20 October at Romania’s request. Romanian President Nicușor Dan has confirmed that the two tankers that caught fire near Sulina last week were hit by drones, and a NATO military source told Reuters they were Russian.

Romanian radar has logged 54 drone intrusions into the country’s air and sea space since Russia’s full-scale invasion, 35 of them this year, and the military has shot down six such targets in 2026, Defense Ministry data show.

Searches in Poland and Lithuania

Within hours, Poland’s Operational Command said it was checking a possible airspace violation by an unknown object overnight into 18 October. Troops, police, and military police searched for a possible crash site south of Lublin after residents reported the loud sound of a flying object around 02:00, Militarnyi reported.

On the morning of 18 October, an unknown drone entered Lithuania’s airspace and triggered air raid alerts, the country’s crisis management center said. NATO jets accompanied it but could not shoot it down because of bad weather, Defense Minister Robertas Kaunas said. Debris preliminarily identified as drone parts was later found in the village of Juodžioniai in Pasvalys district, and the army said the drone may have entered from the direction of Poland.

Romania moved from escorting Russia’s stray drones to firing on them in July, when its F-16s downed three in 72 hours.

Belgium has announced it will accelerate the delivery of surplus Lockheed Martin F-16 fighters to Ukraine. Instead of delivering three flyable F-16s before the end of the year, Brussels will ship 10.

It's unclear how many will be flyable. Previously, Belgian officials explained the first seven secondhand F-16s would include just three airworthy examples. The other four would be broken down for spare parts.

It's good news for Ukraine, but hardly cause for nationwide celebration. The handful of flyable F-16s that should arrive in the coming two months could make good recent F-16 losses. But those shipping-soon Belgian F-16s won't actually grow Ukraine's F-16 fleet by much, if at all.

The dozens of supersonic F-16s in action in Ukraine fly often and fight hard. They shoot down Russian drones and cruise missiles, tangle with Russian warplanes, and lob precision glide bombs at Russian forces on the ground. Russia launched about 2,000 jet-powered drones at Ukraine in September, up from some 350 in June, and F-16s are among the few weapons fast enough to catch them, the Wall Street Journal's editorial board noted. Every 300 flying hours, each jet must go abroad for a lengthy inspection.

Ukraine loses another F-16 to onboard emergency

The main constraint on the pace of F-16 sorties, besides maintenance demands and the availability of trained pilots, is munitions: running low or out of air-to-air missiles and glide bombs, the F-16s routinely aim their 20-mm guns at Russian targets. But even 20-mm ammunition sometimes runs low.

The busy F-16s and their equally busy pilots need reinforcement. But reinforcements are slow coming. Belgium is only slightly accelerating its F-16 shipments amid reports it will eventually give Ukraine all 53 F-16s it's gradually retiring as new Lockheed Martin F-35 stealth fighters arrive to re-equip the Belgian air force.

Further complicating the picture, Norway's six F-16s, promised in 2023, were still being refurbished in Belgium this spring. Some arrived there in pieces.

Yes, Ukraine got 24 fight-ready F-16s from the Netherlands and most of the 19 Denmark promised. But it's lost five of those jets since 2024. And others are so worn out from relentless flying that they're badly in need of maintenance. The Belgian firm Sabena, which services Ukrainian F-16s, has struggled to keep up, and President Volodymyr Zelenskyy has said about half of the jets spend long stretches abroad for repairs. That slows the return of repaired planes and further squeezes the front-line force.

One wing, too few jets

In short, it's possible the Ukrainian air force's 107th Aviation Wing, its sole F-16 unit, has fewer than 40 ready-to-fight F-16s. Those 53 Belgian F-16s will help grow the wing, but piecemeal. Ukraine should expect a handful of operational jets from Belgium this year. Under a schedule from May, the last 27, half the total, may not arrive until 2029.

To be clear, additional F-16s support the 107th Aviation Wing. The Netherlands sold 18 of its old F-16s to Romania for a token price in order to equip a training squadron, funded by a consortium of Ukraine's allies, that feeds trained pilots to the 107th Aviation Wing. But these 18 jets aren't available for front-line use. They don't even legally belong to Ukraine.

Ukraine is running short of its best missiles for hunting Russia’s jet drones. Now MiG-29s are firing 1970s weapons

The delays in supplies of combat-ready F-16s matter because the Ukrainian air force is under stress. Its last few dozen ex-Soviet warplanes, including Mikoyan MiG-29 and Sukhoi Su-27 fighters, are even older and wearier than the ex-European F-16s are. And they've suffered staggering losses in the air and on the ground in nearly 56 months of hard fighting in the wider war.

The air force does have a few ex-French Dassault Mirage 2000s that are at least as capable as the F-16s, but France has donated only a handful of the supersonic jets—and one has crashed. Any further supplies of Mirage 2000s could be complicated by the French presidential election in April 2027. The leading far-right and far-left parties are both friendly toward Russia and hostile to Ukraine.

Some relief is coming, although not quickly. Sweden has pledged 16 surplus JAS-39C/D Gripen fighters to the Ukrainian war effort; the first of these could arrive early next year. Later on, Ukraine also plans to buy 20 newer JAS-39E/Fs. Kyiv has also negotiated to purchase 16 new Rafale fighters from Paris, but the soonest these could arrive is 2028.

For now, F-16s are the main solution to Ukraine's air defense problems. Kyiv surely wishes it had more of them, sooner.

Aviation is one of the most effective ways to counter Russia’s jet-powered drones. Its effectiveness continues to grow due to pilots’ skill and better coordination, Defense Minister Yevhenii Khmara says, Glavcom reports.

Russia’s jet-powered Gerans fly several times faster than the propeller Shaheds Ukraine learned to shoot down, and they remain the main challenge for its air defense. Ukraine downs more than 90% of the slow drones but only about 55% of the jet ones.

“Due to them, our aviation now uses fewer munitions per aerial target. We plan to improve this further,” Khmara states.

Air defense works as a layered system because no single type of weapon is enough, he explains. The layers run from surface-to-air and shoulder-fired missiles to turrets, electronic warfare, interceptor-drone crews, and small-scale air defense, topped by aircraft including Mirage and F-16 jets.

Scaling what works against jet drones

Ukraine already has combat results against the jet drones, Khmara notes. In one engagement, five Bars interceptors destroyed five aerial targets, a 100% hit rate in that case, and the task now is to raise the overall destruction rate and quickly scale the solutions that prove themselves.

Heavy-caliber turrets are adding to that. Their number in service already runs into the hundreds, he adds.

“This direction is being scaled, and systems with greater range are being worked on. In parallel, surface-to-air and shoulder-fired missile systems are also proving effective,” he says.

Preparing for the next generation

Ukraine is also looking past today’s threats, the minister stresses. The ministry is working to supply interceptor drones, aviation and its munitions, missile and artillery systems, turrets and electronic warfare gear, and to plan several steps ahead with enough stock in reserve.

“We also know what solutions Russia is developing, which concern jet drones with a speed of 800 kilometers per hour. We are working on finding countermeasures to the next generation of threats,” Khmara says.

Producers have been tasked with offering proposals and prototypes, he concludes.

The Netherlands will help Ukraine with maintenance, spare parts, and ammunition for F-16 fighter jets, Dutch Prime Minister Rob Jetten promised in a statement on 5 October. He made this and other statements following a phone call with Ukrainian President Volodymyr Zelenskyy.

Russia attacks Ukrainian cities with drones every day, increasingly with jet-powered ones. F-16 fighter jets are one of the effective options for shooting down these UAVs, but Ukraine has far too few of them. The F-16s are used very frequently and therefore require maintenance. About half of the aircraft spend extended periods abroad undergoing repairs and maintenance, Ukrainian President Volodymyr Zelenskyy told the Financial Times this month. The process of returning the aircraft has taken too long, and Ukraine has lost time when the jets were most needed to protect Ukrainian airspace, he said.

“A further strengthening of Ukraine’s air defense is literally vital,” the prime minister said.

Russia’s aggression continues to escalate, and F-16 fighter jets can help stop it

Russia is deliberately attacking civilian facilities and energy infrastructure and wants to make Ukrainian cities uninhabitable, Jetten said, adding that “we must not allow this to happen.”

One effective solution is the use of F-16 fighter jets, while Ukraine faces shortages of both these aircraft and the missiles for them.

Ukrainian F-16 pilots lack air-to-air missiles and take off with only the aircraft’s cannon during some daytime missions, the War Zone reported on 2 September. The M61A1 Vulcan 20mm rotary cannon can pose a danger to civilians on the ground, the outlet noted.

Poland promised to provide Ukraine with F-16 missiles back in September, and several partners, including Poland, have already begun the process of transferring ammunition this month. Other partners include Spain and Belgium, which Foreign Minister Andrii Sybiha mentioned during a meeting with journalists, Hromadske reported on 1 October.

Ukraine critically needs this ammunition, especially as Russia prepares new strikes, Sybiha said.

“Against the backdrop of the fact that we have not yet built up the capability to repel jet-powered drones, against the backdrop of preparations for new strikes, it was critically important to help our military shoot down these drones. The most effective right now—apart from air defense systems, which are very expensive to use constantly against drones—are F-16 fighter jets,” the minister said.

Zelenskyy held talks with the president of France and the prime ministers of Poland and the Netherlands about means of protecting against Russian strikes, he said in his address on 5 October. In particular, he thanked the Dutch prime minister for his prompt response.

Whether Belgian maintenance delays are the reason for the low number of operational F-16s in Ukraine remains disputed

Fewer than 50% of the F-16s delivered to Ukraine may be operational, Defense Express reports, citing a Wall Street Journal (WSJ) editorial published on 29 September.

The Belgian company that services F-16s for Ukraine takes as long as 40 weeks to complete the work, retired US Navy Rear Admiral Mark Montgomery told the WSJ.

That day, Zelenskyy had already announced that Belgium would send three of its fighter jets to Ukraine this year. Ukraine will receive them under an accelerated procedure, he said.

Meanwhile, Ukraine’s Ministry of Foreign Affairs refutes claims that Ukrainian fighter jets have a catastrophically low operational availability rate and excessively long maintenance times.

“Contrary to these claims, our industrial sustainment partners are not only continuing to deliver overhauled aircraft, but are doing so at an increasing pace. Turnaround times are decreasing, not increasing,” Ukrainian Foreign Ministry spokesperson Heorhii Tykhyi said on 2 October.

Reports about the condition of Ukraine’s F-16s should not undermine confidence in international funding supporting F-16 maintenance or cast doubt on the need for additional F-16s from the stockpiles of partner countries, Tykhyi warned.

Ukraine has developed a new missile to knock down Russia's fast, jet-powered Shahed drones, the ones its air defenses catch far less often than older models, President Volodymyr Zelenskyy said on 4 October, Suspilne reported. The weapon, called Nika, has not yet been tested. He announced it during a visit to Kyiv by German Chancellor Friedrich Merz.

Russia's plants turn out an estimated 3,000 jet-powered Geran-4 and Geran-5 drones a month, Ukraine's military intelligence estimates, and the jets fly fast enough to outrun the cheap interceptors built for slower, propeller-driven Shaheds. Ukraine plans about 400 units of just one of five interceptor models it is testing by the end of October, as it scrambles to close the gap before winter.

A new missile heads into testing

Both the Ukrainian and German sides have reacted positively to the missile, Zelenskyy said, though he stayed cautious on the result: for now, he said, it only "could be positive." In the same remarks, he announced a successful test of a separate system, the German-Ukrainian interceptor Spys.

Russia adds new weapon to its jet-powered drones, even more dangerous: 40-kilogram charge made to sever high-voltage pylons and iron bridges

Ukraine shoots down 85-92% of propeller-driven Shaheds, Zelenskyy said. Against the jet-powered variants, interception falls to roughly 50-60%, he noted at the press conference with Merz. F-16 fighter jets help close the gap, he said.

From interceptor drones to a new missile

Over the past month, Ukraine tested a new generation of drone interceptors built for the jet-Shahed threat. On 15 September, one struck a Shahed in trials, though Zelenskyy said developers still needed to refine its control system. On 19 September, he said the Security Service of Ukraine (SBU) had created its own interceptor drone and used it to down a jet Shahed in combat. Nika adds a purpose-built missile to that mix.

Ukraine has lost another Mikoyan MiG-29 fighter and its pilot. The Thursday shoot-down extends the steady attrition of the Ukrainian air force MiG fleet, potentially drawing down the fleet to its pre-war strength.

That means Ukraine may have lost as many of the twin-engine, supersonic MiG-29s as it has received from its allies or restored from surplus stocks since February 2022.

It's an ominous milestone. The Soviet-vintage MiG-29 is no longer the Ukrainian air force's most important fighter. That honorific belongs to the air force's ex-European Lockheed Martin F-16s.

But the MiG-29 is still the air force's second most important fighter—and will remain so through 2027 as Ukraine awaits its first ex-Swedish Saab Gripens, due early next year, and French-made Dassault Rafales, due from 2028. Ukraine sorties MiG-29s for ground attack missions targeting Russian troop concentrations, strikes on Russian air defense systems, and air defense sorties over Ukrainian cities and ports.

The air force announced the loss of the MiG-29 and its pilot, Capt. Marat Mambetov, shortly after it occurred on Thursday. Mambetov, 25, was a flight commander in the 40th Tactical Aviation Brigade, known as the "Ghost of Kyiv" brigade. "Flying a MiG-29 fighter jet, [Mambetov] carried out missile and bomb strikes against Russian occupiers along one of the front-line directions," the air force stated. "During the mission, his aircraft was hit by an enemy missile. The pilot ejected, but tragically did not survive."

It's the 37th confirmed combat loss of a Ukrainian MiG-29 since Russia widened its war on Ukraine in February 2022, according to a tally by the Oryx open-source intelligence collective. Oryx has also registered damage to an additional three Ukrainian MiG-29s.

Thirty-seven write-offs, plus the likely grounding of several previously flyable MiG-29s owing to intensive wear and tear since 2022, may have reduced the Ukrainian air force's MiG-29 fleet to around three dozen active jets.

Fighter subtraction

The math is simple. The air force probably had between 30 and 35 MiG-29s in service when Russia attacked in February 2022. As losses cut into the fleet, Poland donated 14 surplus MiGs, Slovakia donated 10, and Azerbaijan reportedly donated three. Meanwhile, Ukrainian engineers tapped a global pipeline of spare parts to reactivate an estimated 20 grounded MiG-29s moldering in hangars at various Ukrainian airfields.

That's as many as 82 MiGs in and, as of Thursday, 37 out owing to Russian action—plus additional jets grounded due to airframe fatigue. The resulting active fleet should number around three dozen planes, around as many as Ukraine had on the eve of the wider war.

There aren't many more old MiGs that Ukraine could obtain to bolster the fleet. Poland still has as many as nine very tired airframes, but Kyiv and Warsaw have consistently failed to negotiate a transfer. There may yet be a few ex-Soviet MiG-29s, grounded for years or even decades, that Ukrainian engineers can restore to flightworthy status. Other than that, options are scarce.

Ukraine’s Swedish radar planes have flown inside Russian missile range for six months. None has been shot down.

The three dozen MiGs still in the inventory may have to last a little while alongside the few survivors of Ukraine's other Soviet-vintage warplanes, including Sukhoi Su-27s, Sukhoi Su-24s, and Sukhoi Su-25s.

Older Western types—the 80 or so F-16s European allies have pledged, about half delivered, as well as potentially a dozen or so ex-French Dassault Mirage 2000s—are steadily replacing the ex-Soviet jets. (So far, Ukraine has lost five F-16s and one Mirage.) Next year, the transformation of the Ukrainian air force from a largely Soviet-equipped force to a largely Western-equipped force will accelerate when the first of 32 Gripens arrive. Sixteen Rafales are to follow from 2028.

Barring catastrophic combat losses among Western types and assuming Ukraine can maintain and arm these new warplanes, by the end of 2027, the air force may not need its remaining MiGs and Sukhois, which by then could be very tired.

Russian missiles are steadily reducing the MiG and Sukhoi fleets, effectively forcing Ukraine to switch to new types.

Less than 50% of the F-16 fighter jets delivered to Ukraine may be operational, Defense Express reports, citing a Wall Street Journal (WSJ) editorial published on 29 September. On the same day, Ukrainian President Volodymyr Zelenskyy said that Belgium would deliver three F-16 fighter jets this year.

F-16s are used extensively to intercept Russian cruise missiles and drones. As the number of Russian attacks has increased, these aircraft have become particularly important for Ukraine. However, the jets Ukraine receives are old, and keeping them flying takes regular maintenance, extra work, and hard-to-find parts.

Routine inspections are taking as long as 40 weeks in Belgium, retired US Navy Rear Admiral Mark Montgomery told the WSJ.

The maintenance process for these aircraft for Ukraine is lengthy

A likely reason for the problem is the lengthy maintenance process handled by Belgian company Sabena Aerospace Engineering, according to the WSJ, whose questions the company declined to answer. This process, according to Defense Express's estimates, takes 6–20 times longer than maintenance in the United States, which usually takes between 2 and 6 weeks. Ukraine uses the services of the Belgian company, meaning its F-16s are not being serviced quickly enough.

Delivering three additional fighter jets will not significantly help the Ukrainian military until the issue with aircraft maintenance times is resolved, Defense Express notes. The lengthy turnaround may be caused by a large maintenance backlog at the company, limited capacity, or logistical constraints, and older jets may need extra work and scarcer parts.

The delivery is part of an earlier commitment. Belgium plans to provide seven fighter jets this year: three for operational use and four for spare parts, Belgian Defense Minister Theo Francken said in June.

"I'll propose to the government to send all our F-16s to Ukraine in the coming years. It depends on having the F-35s in place because, of course, we have DCA [dual-capable aircraft] capacity. We have our role in the nuclear doctrine of NATO," Francken said.

Belgium has pledged its entire F-16 fleet of 53 aircraft as F-35s replace them, according to Defense Express.

F-16s in Ukraine have already shot down several thousand Russian aerial targets

F-16s operated by Ukrainian pilots have shot down more than 3,150 aerial targets. These include 666 cruise missiles and around 2,500 drones of various types. The aircraft have also carried out more than 650 strikes against Russian ground targets, Lieutenant General Anatolii Kryvonozhko, Commander of the Ukrainian Air Force, said during a meeting between a Ukrainian Air Force delegation and representatives of Lockheed Martin on 29 September.

At the meeting, Conor McGuire, Lockheed Martin's head of F-16 capability development, highly praised the combat use and operation of F-16s by Ukrainian pilots and the entire ground aviation personnel. He also expressed his intention to help Ukrainians enhance the capabilities of the existing platform, the statement said.

France delivered additional MICA air-to-air missiles and 30mm cannon ammunition for Ukraine's Mirage 2000 fighter jets, Militarnyi reported, citing France's Armed Forces Ministry.

Delivering an aircraft is one step, keeping it armed is another. France's weapons resupply reflects a shift from one-off hardware transfers to sustained combat support as Russia's aerial campaign against Ukrainian cities grinds on.

What MICA does

The MICA, developed by MBDA, comes in two versions: radar-guided (MICA RF) and infrared (MICA IR). It weighs about 112 kg, flies at Mach 4.9—nearly five times the speed of sound—and can engage targets 60 to 80 km away.

Ukraine's Mirages have also carried older Magic 2 missiles limited to roughly 20 km. MICAs were reportedly included with the original donation, but the supply may have been limited, which would explain why the Magic 2s stayed in use. MICA triples to quadruples that engagement window, letting pilots intercept cruise missiles far earlier in their flight path. The fresh delivery keeps Ukraine's small fleet supplied with the missiles that make these longer-range interceptions possible.

The 30mm ammunition feeds the Mirage's two built-in DEFA 554 cannons, which fire at a selectable rate of 1,200 or 1,800 rounds per minute. A pilot who uses the gun on a Shahed drone saves a MICA for a target that actually needs one.

Ukraine's F-16 operations follow a similar logic: pilots use their 20mm Vulcan cannons alongside AIM-9 and AIM-120 missiles, though Zelenskyy called the missile option expensive—used when nothing else can reach a jet drone, because "a human life is more important."

A Ukrainian Mirage 2000 shot down a Russian Kh-101 cruise missile during its very first combat mission, on 7 March 2025. France has delivered about a dozen modified Mirage 2000-5F jets since February 2025, and the fleet is still growing.

A lieutenant colonel flying a U.S.-made F-16 fighter jet was killed during the overnight aerial strike while on duty, the Air Force said on June 29.

Russia launched a "massive" missile and drone strike across Ukraine early on June 29, unleashing 537 aerial targets, including 477 drones and 60 missiles, according to the Air Force..

Maksym Ustymenko, born in 1993, was killed after shooting down seven aerial targets, the Air Force said in a statement. The Air Force added that his aircraft was damaged while he was trying to shoot down the last one, losing altitude and crashing.

"Maksym Ustymenko did his best to take the plane away from the settlement, but did not have time to eject," the Air Force said on Telegram, honoring that he died "like a hero."

"The work of Ukrainian pilots is extremely dangerous and risky, both when striking enemy ground targets and repelling air attacks," the Air Force added, saying that the F-16 pilots destroy dozens of Shahed-type drones.

In his evening address, President Volodymyr Zelensky posthumously awarded Ustymenko with the Hero of Ukraine award.

"Today, he was killed defending our skies and our people from yet another massive Russian attack... It is painful to lose people like him," Zelensky said in offering condolence to loved ones.

Russia has intensified its aerial campaign on Kyiv and other cities over the past month. Zelensky said that Russia has launched over 2,700, or roughly 9.5%, of the total number of Shahed-type drones deployed during the entire full-scale war in June alone.

Though well protected with Western air defense systems compared to other cities, Kyiv has also faced a number of deadly attacks in June, with the June 17 missile and drone strike on Kyiv killing 30.  

The Air Force said that Ukraine had to use "all available means" to repel the Russian aerial attack overnight on June 29, including elite F-16 jets.

Ukraine received its first batch of F-16 jets in the summer of 2024, but it has not revealed many details about how and where they are used in operations since they are a high-priority target for Moscow. Their pilots have received months of training abroad.
