The Ukrainian F-16 Su-35 engagement has been officially confirmed by the United States’ most senior military officer. Gen. Dan Caine, Chairman of the Joint Chiefs of Staff, told the Senate Appropriations Committee on July 21, 2026, that a Ukrainian F-16 Fighting Falcon had scored an air-to-air kill against a Russian fighter jet, marking the first time an American-designed aircraft has downed a Russian warplane in aerial combat since Ukraine received the jets in 2024. The kill almost certainly refers to the July 8, 2026 shootdown of a Russian Su-35S Flanker-E on the eastern front, a development that Ukrainian defense outlet Militarnyi confirmed following Caine’s Senate remarks. Russia’s defense ministry has not officially acknowledged the loss.
What General Caine Told the Senate
Caine made the disclosure while testifying before the Senate Appropriations Committee about the Department of Defense’s nearly one trillion dollar supplemental budget request for FY2026. When asked about the state of Ukraine’s air defenses after a three-year pause in U.S. air-defense funding, Caine used the air-to-air kill as the clearest evidence available that Kyiv’s aerial capabilities had matured significantly since the F-16s first arrived.
Caine said: “I want to highlight the incredible work the Ukraine industrial base is doing as they scale their own capabilities. Recently we had the first air-to-air kill where a Ukrainian F-16 shot down a Russian fighter, so I think their ability to scale their layered defense has come a long way over the last couple of years.” Caine did not specify which type of Russian aircraft was destroyed, the date of the engagement, the weapons used, or the circumstances under which it occurred. He framed the kill as evidence of Ukraine’s expanded anti-access and area denial network rather than as an isolated tactical event.
The July 8 Su-35 Shootdown: What Is Known
The kill almost certainly refers to an engagement on July 8, 2026, when Ukraine’s Air Force announced it had shot down a Russian Su-35 on the eastern front, without initially identifying the weapon or platform responsible. Ukrainian defense outlet Militarnyi assessed after Caine’s July 21 remarks that the aircraft was a Russian Su-35S Flanker-E/M, one of Moscow’s most capable frontline fighters. Ukraine sent a drone to the crash site afterward, which confirmed the wreck and provided visual verification of the kill.
Several Ukraine-linked OSINT channels claimed the kill was achieved through a coordinated ambush involving three F-16s and a Patriot surface-to-air missile system, with one F-16 reportedly flying lower and acting as bait for the Russian Su-35. Other accounts described the engagement as involving a Ukrainian MiG-29 used to draw the Su-35 into range before two F-16s engaged the Russian fighter. The weapon used in the engagement has not been officially disclosed by the Ukrainian Armed Forces, though analysts widely assessed that an AIM-120C-8 AMRAAM air-to-air missile, the type Ukraine is known to field on its F-16s, was the most likely candidate. French OSINT accounts published footage purportedly showing the burning wreckage of the Su-35, captioned with a reference to the Third Army Corps’ area of responsibility. UNITED24 Media
Russia’s Response and the Competing Narrative
Russia’s defense ministry has not acknowledged the loss of the Su-35, which is consistent with Moscow’s general approach to publicly confirming aircraft losses throughout the war. Pro-Russian military bloggers on Telegram confirmed a Su-35 went down and said the pilot survived and ejected safely, while other Russian channels claimed a Patriot battery delivered the fatal shot. Kyiv Post
The Patriot attribution claim, which surfaced on Russian-aligned Telegram channels almost immediately after the July 8 shootdown was announced, reflects a pattern of Russian information operations attempting to deny Ukraine’s Western-supplied aircraft direct credit for kills that might otherwise reinforce the case for continued Western military support. No evidence has been produced to support the Patriot-only attribution. The most detailed Russian pro-military account, the Fighter-Bomber Telegram channel with ties to Russian Aerospace Forces frontline units, appeared to confirm the Su-35 loss while stating the pilot was rescued, without disputing that Ukrainian aircraft were involved in the engagement.
Why This Kill Matters: The Technical Odds Ukraine Overcame
The significance of a Ukrainian F-16 scoring an air-to-air kill against a Russian Su-35 is amplified by the significant technical disparity between the two aircraft. Most of Ukraine’s F-16s were given to Kyiv by the Netherlands and Denmark, who sent rebuilt 1970s and 1980s-era F-16A and B airframes, closer to the F-16s that the U.S. Air Force flew in the early 2000s than to today’s newer models. Kyiv Post
The Su-35S is one of the most modern fighters Moscow flies. Its Irbis-E radar can detect a fighter-sized target at up to 250 miles in a narrow search mode, far beyond the range of the 1990s-era AN/APG-66(V)2 radar on Ukraine’s F-16s. The Su-35 also carries the longer-reaching R-77M missile, credited with a range of roughly 120 miles, against the 75 to 100 miles of the AIM-120C-8 AMRAAMs Ukraine is known to field. Kyiv Post
That the kill was achieved despite these disadvantages points to the tactical innovation that has characterized Ukraine’s use of its F-16 fleet, particularly the integration of ground-based radar from Patriot batteries and other systems to extend the effective detection range available to Ukrainian pilots operating aircraft with technically inferior onboard sensors.
How Ukraine Has Used Its F-16s Until Now
The Su-35 kill represents a significant operational shift in how Ukraine’s F-16 fleet has been employed since the aircraft first arrived in summer 2024. Until now, Ukraine has primarily used its F-16s defensively to knock down incoming drones and cruise missiles, not offensively hunting enemy aircraft. Kyiv Post
Ukraine’s F-16s have shot down 2,200 of roughly 3,000 Russian drones and missiles intercepted by the air force, according to Ukrainian Air Force spokesman Yuriy Ihnat, making drone and missile interception by far the most operationally significant role the aircraft has played in the conflict. The transition toward offensive counter-air missions, targeting Russian aircraft rather than Russian munitions, represents a new stage in Kyiv’s air campaign. Kyiv Post
Ukraine’s F-16 fleet remains modest in size. Around 39 aircraft are thought to be in service, according to the specialist Ukrainian outlet Defense Express. Ukraine has lost at least three F-16s, and said in late June 2025 another of the jets had sustained damage, killing the pilot. Ukraine is expected to receive roughly 100 F-16s in total, supplied mainly by Norway, Belgium, Denmark, and the Netherlands, with deliveries subject to ongoing maintenance and upgrade timelines.

Ukraine’s Broader Air Power Expansion
The Su-35 kill arrives amid a broader expansion of Ukraine’s air power that extends well beyond the F-16 program. Ukraine signed a contract on June 30 to deliver 16 Gripen fighter aircraft, valued at about $2.54 billion, along with 16 older Gripen C/D aircraft starting in 2027, as well as 16 Rafale fighter jets as French President Emmanuel Macron outlined on July 13. UNITED24 Media
Ukraine’s homegrown interceptor-drone industry has scaled rapidly in the past year, with some producers now capable of turning out over 100,000 drones per month. Washington is also in advanced negotiations on a multibillion dollar weapons-production deal with Kyiv. Secretary of State Marco Rubio described the Ukrainian armed forces as “the strongest, most powerful armed forces in all of Europe” in May 2026, months before the CIA director confirmed that Russian recruits survive just 20 to 30 minutes on Ukraine’s front lines due to the country’s fierce drone-fighting tactics.

Broader Implications
A Ukrainian F-16 shooting down a Russian Su-35 is a milestone with implications that extend well beyond a single aircraft loss. It demonstrates that Ukraine’s air force has evolved from a defensive posture, intercepting inbound missiles and drones, toward a capability for offensive counter-air operations against Russian fighters. It validates the logic of the Western coalition’s F-16 transfer program and gives Allied governments additional evidence to support continued and expanded air power commitments to Kyiv. For Russia, the loss of a Su-35 to a technologically inferior aircraft is both a tactical and a psychological data point, particularly given the competing narratives Russian-aligned channels have already deployed to minimize the significance of the engagement.
The engagement also illustrates the growing role of integrated multi-system tactics in modern air combat. The coordination between ground-based Patriot radar, Ukrainian F-16s, and possibly a decoy aircraft to achieve the kill reflects lessons in networked warfare that military analysts in NATO countries are already beginning to document and absorb.
