Another of Russia's Su-57 stealth fighters has burned out on the ground, Ukrainian military news outlet Militarnyi reported. A Ukrainian Telegram channel blamed an engine start gone wrong and published satellite images of the scorched airfield.

Russia's war against Ukraine leans on warplanes that strike from standoff range, and Ukraine has spent this year hunting them on their airfields. Its newest fighter is a rare sight in that fleet: Ukrainian intelligence estimated Russia had about 20 Su-57s, against 135–140 Su-35S and 140–145 Su-30 jets, and could not tell how fast more are built.

Satellite images show where the jet burned

The fire broke out at the Akhtubinsk airfield in Russia's Astrakhan Oblast on 29 October. The Ukrainian Telegram channel Absolutely Reliable Source said the multirole fighter caught fire during a malfunction at engine start. It said the jet burned out completely. Militarnyi called the cause preliminary.

The channel's satellite images show a dark scorch mark and debris on open ground between the airfield's taxiways.

Akhtubinsk has seen Su-57s hit before. Ukrainian drones first damaged Su-57s there in June 2024, and Ukrainian intelligence said two were likely hit.

The fourth Su-57 hit or lost this year

Militarnyi counted the fire as the fourth time a Su-57 was hit or lost in 2026. Ukraine's General Staff said drones hit several Su-57s and a Su-34 at the Shagol airfield in Chelyabinsk Oblast on 25 April. Ukrainian intelligence later said the state of those jets was unknown.

On 23 July, a Su-57 crashed in Moscow Oblast. A Russian Telegram channel said Russia's own air defenders shot it down.

Russia's air force received two new Su-57s in September, its second batch this year, Militarnyi reported.

Ukraine keeps hitting Russian warplanes on the ground. On 29 October, Ukraine's Navy said its Neptune missiles destroyed two Su-34s at the Marinovka airfield in Volgograd Oblast. Two weeks earlier, it reported hitting six Su-34s at Borisoglebsk in Voronezh Oblast. Russia uses those bombers to drop glide bombs on Ukrainian towns.

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.
