Russia's Latest Gen Su-57 Stealth Jets Fail to Intercept Ukrainian Drones Over Omsk
AI Analysis
Russian Su-57 stealth fighters were deployed to intercept Ukrainian drones targeting the Omsk oil refinery, but failed to prevent damage to the facility. Evidence suggests Russia is increasingly utilizing its limited Su-57 fleet for counter-UAS roles, modifying them with external weaponry compromising their stealth capabilities. The attack represents Kyiv's deepest strike into Russian territory to date, halting operations at a major oil refinery.
Key Takeaways
- Su-57s were used in a defensive role against drones, indicating a shift in deployment priorities.
- The jets were observed with R-73 missiles and a 101KS-N electro-optical pod, suggesting adaptation for engaging smaller aerial targets.
- The Omsk refinery, processing 440,000 barrels/day, has halted operations following the attack.
- Russia possesses a limited number of Su-57s (around 30), making their loss a significant concern.
- Prior sightings and photos suggest a trend of repurposing the Su-57 for air defense, potentially due to risk aversion regarding frontline combat.
Why It Matters
The use of advanced, expensive assets like the Su-57 for counter-drone duties highlights Russia’s struggle to effectively defend against Ukrainian drone attacks. Kyiv’s ability to strike deep within Russia demonstrates the increasing range and effectiveness of Ukrainian drones, and the vulnerability of critical infrastructure. This event may force Russia to further re-allocate resources towards air defense and potentially accelerate development of more robust counter-UAS systems.
Russia deployed its latest-generation Su-57 stealth fighters to intercept Ukrainian drones during Monday’s attack on the Omsk oil refinery – but the facility was hit despite the effort.
During the attack on Russia’s largest refinery that marked Kyiv’s deepest strike into Russia to date – at over 3,000 kilometers (1,864 miles) from the border – online footage from locals has shown the silhouette of the elusive Su-57 shrieking overhead.

In one such piece of footage shared by the Ukrainian monitoring channel Exilenova+, the channel said the Su-57s managed to down only one drone, while others reached their targets.
In another video shared by Exilenova+, the channel said the jet was hunting down the drones, with the silhouette of the Su-57 faintly visible up in the sky.
The refinery damaged was Russia’s largest, processing 22 million metric tons of crude oil (about 440,000 barrels per day) in 2024 and producing approximately 5 million tons of gasoline and 8 million tons of diesel.
Sources cited by Reuters and Ukrainian monitoring channels confirmed that operations have been halted at the plant, though reports vary as to the extent of damage and the exact refining units struck.
With a known number of around 30 units – falling far short of Moscow’s planned delivery of 76 additional airframes by 2027 – the Su-57s have been among Russia’s most elusive, as they are rarely fielded in combat against Ukraine, presumably due to fears of losing one to Ukrainian forces if intercepted.
At the same time, military outlet Defense Express, citing a recent report from The War Zone, noted that the latest sighting follows recently publicized photos suggesting the jet’s relegation to anti-drone duties.
In the photos – whose origins remain unknown – the Su-57 was seen fitted with R-73 air-to-air missiles fitted on the wing pylons instead of the internal weapon bay, which would compromise the jet’s stealth capability.
The War Zone also noted a pod containing the 101KS-N electro-optical suite, which the outlet argued could also allow the jet to engage small aerial targets such as drones.
Russia has explored various ways to utilize the Su-57 platform, which include recent reconfigurations – including a two-seater version flight-tested recently – for exports to aid the cash-strapped economy.
An earlier patent for the two-seater version also hinted at an “air command post” function to direct other aircraft, both piloted and uncrewed drones.
The Su-57s were confirmed to have been struck twice throughout Russia’s invasion of Ukraine – once in June 2024 and another in April 2026 – both times on the ground.
