Ukrainian F-16 downs Russian Su-35 in historic first
A Ukrainian F-16 has scored its first confirmed air-to-air kill of the war, Gen. Dan Caine told U.S. lawmakers, after Ukrainian media said the jet downed a Russian Su-35 over eastern Ukraine on July 8. The milestone puts Western fighters into direct combat with advanced Russian fighter jets for the first time.
Key Takeaways
- Chairman of the Joint Chiefs Gen. Dan Caine told Congress a Ukrainian F-16 achieved the war's first air-to-air kill of a Russian fighter.
- Ukrainian media identified the target as an Su-35 downed over eastern Ukraine on July 8; Caine did not name the aircraft type.
- A Russian Telegram channel linked to Moscow's air force claimed the Su-35 pilot survived after ejecting.
- Hindustan Times noted no public wreckage footage has surfaced, so verification still rests mainly on official statements.
- Ukraine is thought to operate about 39 F-16s and is set to receive more from Belgium.
The claim marks a rare public nod from Washington that Kyiv's U.S.-made fighters have moved beyond missile and drone intercepts into air combat against Russian fighter jets. For more on emerging defense tech, see our Future Tech & AI Wonders hub.
What did U.S. officials actually confirm?
Speaking to U.S. lawmakers on Tuesday, Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said: "Recently, we had the first air-to-air kill where a Ukrainian F-16 shot down a Russian fighter."
He told lawmakers the U.S.-provided aircraft have proven a huge success and that Ukraine's layered defenses have come a long way. He did not specify which Russian plane was hit or share operational details, according to the New York Post.
Was the downed jet a Russian Su-35?
Ukrainian media pointed to an Air Force claim from July 8 that an Su-35 was shot down over eastern Ukraine. That identification is what linked Caine's soundbite to one of Russia's more capable fourth-generation fighters.
A popular Russian Telegram channel with purported air force ties said three Ukrainian aircraft and a Patriot battery targeted an Su-35, that two of the jets were F-16s, and that the Russian pilot survived. Hindustan Times flagged that there is still no widely circulated wreckage footage, leaving the kill reliant on statements rather than open-source imagery.
Why does this F-16 milestone matter now?
F-16s first reached Ukraine in summer 2024 after NATO pledges totaling roughly 80 Lockheed Martin jets, though deliveries have been delayed and some airframes are for spare parts. Kyiv has mainly used them to shoot down Russian missiles and drones heading for cities.
Both the F-16 and Su-35 are fourth-generation fighters—capable but not stealthy like U.S. F-35s or F-22s. Still, the F-16s are more advanced than the Soviet-era MiG-29s and Su-27s Ukraine flew for decades.
Ukraine's fleet is modest: about 39 F-16s in service after losing at least three, per Ukrainian outlet Defense Express. Belgium is expected to send seven more this year and eventually transfer its full fleet of 43. Kyiv has also agreed to buy 16 Swedish Gripens, expected within about three years.
Rocket shortages have previously limited the jets' punch—including a nearly month-long missile shortfall in late 2025—so an air-to-air win against Russian fighter jets would signal that Western jets are finally contesting the skies more directly.
