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.

Ukraine is counting on buying part of Lockheed Martin’s growing output of ballistic missile interceptors, President Volodymyr Zelenskyy said. He met the US company’s team in Kyiv on 19 October and also raised servicing and repairing F-16 fighter jets inside Ukraine.

Russia keeps striking Ukraine’s power grid with ballistic missiles, and interceptor supplies fall short of that threat. Kyiv is working every route to more Patriot missiles, from US deliveries to allies’ stocks, and some have stalled. Greece, for one, has not confirmed it will hand any over, citing its own defense needs. A purchase from the missiles’ maker would add one more route.

Growing output, F-16 repairs in Ukraine

Lockheed Martin builds the PAC-3 MSE interceptors fired by Patriot air defense systems, as well as the F-16. Zelenskyy said both matter against Russian ballistic missiles and jet-powered Shahed drones. Neither area is easy right now, he added.

“We count on the opportunity to purchase some of them to protect more lives,” he wrote.

On 28 July, Zelenskyy met the company in Washington to discuss joint production. That came weeks after US President Donald Trump pledged Ukraine a license to manufacture Patriots.

A batch reportedly stuck in Washington

Meanwhile, US Defense Secretary Pete Hegseth has not signed off on a “significant” batch of Patriot missiles, Ukrainian officials told the Kyiv Independent. One official said allies had already paid for them. A US government official called the claims untrue, and the Pentagon did not respond. A NATO official said allied-funded deliveries, including air defense, continue. A second NATO official said some shipments could be delayed, but likely not for political reasons.

Zelenskyy told Bloomberg on 18 October that the US delivers only 12 Patriot interceptors a month. On 20 October, interceptors topped his list in a call with US Secretary of State Marco Rubio.

No purchase was announced, so new interceptors from this route remain a prospect. Meanwhile, partners’ early warnings of Russian ballistic launches have gone missing three times recently, Zelenskyy wrote. Those warnings give air defenses extra minutes to prepare.

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.
