Ukraine has achieved a major milestone in its air war with Russia, with a Ukrainian F-16 reportedly scoring its first-ever air-to-air victory by shooting down a Russian Su-35 fighter jet. The development was confirmed by General Dan Caine, Chairman of the U.S. Joint Chiefs of Staff, during testimony before U.S. lawmakers, marking the first publicly acknowledged aerial kill by a Ukrainian-operated F-16.
Although General Caine did not identify the Russian aircraft, the announcement aligns with Ukraine’s July 8 claim that its Air Force destroyed a Russian Su-35 over eastern Ukraine. Russian military-linked Telegram channels also acknowledged the loss of an Su-35, claiming the aircraft was engaged by multiple Ukrainian aircraft and a Patriot air defense system, while stating the pilot survived.
The engagement is significant because it marks the combat debut of Ukraine’s Western-supplied F-16s in an air-to-air role. Until now, the aircraft had primarily been used to intercept Russian cruise missiles, drones, and other aerial threats rather than engaging Russian fighter jets directly.
Ukraine began receiving F-16s in 2024 after several NATO countries pledged around 80 aircraft, though deliveries have been slower than expected. The fighter jets represent a major upgrade over Ukraine’s aging Soviet-era MiG-29s and Su-27s, providing improved radar, weapons integration, and combat capabilities.
Despite their arrival, Ukraine’s F-16 fleet remains relatively small, with an estimated 39 aircraft currently in service. The fleet has also suffered losses during the conflict, highlighting the risks faced by Ukrainian pilots operating in heavily contested airspace.
The reported shootdown of one of Russia’s most capable fourth-generation fighters, the Su-35, demonstrates the growing effectiveness of Ukraine’s modernized air force and could signal a new phase in the aerial battle over the conflict. With additional Western aircraft and future deliveries of Swedish Gripen fighters expected in the coming years, Ukraine continues to strengthen its ability to challenge Russian air power.
