US General Confirms Ukrainian F-16's First Air-to-Air Kill of a Russian Fighter

Joint Chiefs Chairman Gen. Dan Caine told the Senate Appropriations Committee on July 21, 2026 that a Ukrainian F-16 had shot down a Russian fighter, the first air-to-air kill for the type in Ukrainian service.

Gen. Dan Caine, chairman of the U.S. Joint Chiefs of Staff, told the Senate Appropriations Committee on July 21, 2026 that a Ukrainian Air Force F-16 has shot down a Russian fighter in air-to-air combat. It is the first such kill credited to the type since it entered Ukrainian service in August 2024.

"Recently we had the first air-to-air kill where a Ukrainian F-16 shot down a Russian fighter," Caine said during testimony on defense appropriations. He did not identify the aircraft, the date or the location, and placed the remark inside a broader assessment of Ukraine's air defenses. "I want to highlight the incredible work that the Ukraine industrial base is doing as they scale their air-to-air capabilities," he told senators, adding that "their ability to scale their layered air defense has come a long, long way."

The testimony lines up with an engagement Ukraine claimed on July 8, 2026, when a Russian Su-35 came down near Mostky in Luhansk Oblast, roughly 42 km behind the front line. According to accounts of the engagement, a single Ukrainian F-16 was releasing glide bombs at low altitude when a Su-35S on combat air patrol accelerated toward it, only to be engaged by a second pair of F-16s trailing lower and further back. Ukrainian sources say the kill was scored with an AIM-120C-8 AMRAAM; Russian Telegram channels described the encounter as "3 enemy aircraft + a 'Patriot' system against one of ours." The Russian pilot ejected. The loss is recorded in the GlobalMilitary.net tracker as an Su-35 shot down on July 8.

The claim had circulated for two weeks without Western corroboration, and neither Kyiv nor Washington had confirmed the circumstances. Caine's remark is the first acknowledgement from a senior U.S. official.

Ukraine received its first F-16s in mid-2024 and now fields roughly 31 airframes across two variants, 23 F-16AM and 8 F-16, according to GlobalMilitary.net inventory data for 2026. Until now the fleet's record had been almost entirely defensive: Ukrainian officials credit the F-16 with more than 1,000 drone and cruise missile intercepts, a mission that has already cost several aircraft and pilots. An offensive counter-air kill is a different proposition, requiring the fighters to operate inside a layered network alongside ground-based interceptors and a NATO-supplied picture of Russian fighter activity.

The Su-35S remains the most capable fighter Russia operates in numbers over Ukraine. GlobalMilitary.net has logged eight Su-35 losses in the Russia-Ukraine War, out of 289 Russian aircraft written off in the conflict since 2022, and the type is still a core element of the Russian Air Force fleet.

Neither the U.S. nor Ukraine has released further detail on the engagement, and Ukraine has kept specific tactics undisclosed for operational security. Kyiv continues to receive F-16s from European donors and separately agreed a roadmap with France in July for 16 Rafale fighters to be delivered by 2028.
