Fetesti Air Base, Romania — Ukraine has increasingly relied on American-made F-16 fighter jets to counter Russia’s jet-powered drones amid ongoing conflict, according to military officials and experts. Faced with a shortage of interceptor missiles and a barrage of drone attacks, Kyiv has employed its limited fleet of roughly 50 F-16s to serve as a critical line of defense.
President Volodymyr Zelensky recently characterized the F-16 as one of the most effective tools for shooting down these relatively low-cost drones, which have severely threatened Ukrainian cities. However, the constant operational tempo is straining the fighter jets, with approximately half of the fleet currently grounded for maintenance in Europe. Ukrainian officials emphasize the urgency of replenishing and sustaining the fleet, as training pilots and securing ammunition remain significant challenges.
David A. Deptula, retired U.S. Air Force lieutenant general and head of the Mitchell Institute for Aerospace Studies, noted that Ukraine has been compelled to use a small number of fighter jets as a substitute for a more comprehensive layered air defense system. He warned that this approach is "not a sustainable long-term proposition" due to the rapid consumption of valuable assets.
Despite these constraints, Ukrainian F-16s have reportedly intercepted a substantial number of threats. Ukrainian Air Force spokesman Col. Yurii Ihnat stated that these jets had successfully shot down as many as 90% of incoming cruise missiles during recent attacks. He also highlighted a pilot who downed 10 jet-powered drones in a single sortie. Lt. Gen. Anatolii Kryvonožhko, commander of the Ukrainian Air Force, reported that by late September, Ukrainian F-16s had intercepted 666 cruise missiles and about 2,500 drones of various types.
The introduction of the F-16 to Ukraine’s air defenses was delayed by lengthy political and logistical hurdles. The jets, manufactured by Lockheed Martin, require U.S. government approval for transfer. Zelensky began requesting them shortly after Russia’s full-scale invasion in 2022. However, the Biden administration initially hesitated, concerned about escalating tensions with Russia and Ukraine’s capacity to maintain the aircraft. The first batch, donated by Denmark, the Netherlands, and Norway, did not arrive until more than a year later, with pilot training programs commencing in mid-2023.
Since deployment, the jets have flown nearly continuous missions. Five F-16s have been damaged or destroyed in combat, including the first pilot lost, Lt. Col. Oleksiy Mes, who was shot down during an early air engagement. While the jets have conducted over 650 airstrikes against Russian ground targets, their primary use has been air defense, as they lack long-range strike capabilities required to hit deeper Russian military assets. Those roles remain filled largely by French-made Mirages and Ukraine’s Soviet-era aircraft.
Ukraine is working to expand its fleet with the acquisition of 20 new Gripen fighter jets from Sweden, alongside 16 older models being donated. France has also committed to selling Rafale fighters, to be delivered in the coming years. Both aircraft types can carry "deep strike" missiles capable of hitting targets hundreds of kilometers inside Russian territory. Negotiations with Lockheed Martin are also underway for Ukraine to acquire newer F-16 models equipped with longer-range missiles, pending U.S. approval.
Pilot training is taking place not only in the United States but also at Fetesti Air Base in Romania, the only location outside the U.S. authorized to train Ukrainian pilots in the F-16. Since September 2024, 19 Ukrainian pilots have graduated from the program operated by Lockheed Martin. Training focuses heavily on counter-drone tactics, reflecting the evolving nature of aerial threats in the conflict.
A pilot-in-training at Fetesti described the rapid transformation of the air war in Ukraine, emphasizing that adaptation is crucial as the nature of combat changes constantly. “We don’t have any choice,” he stated, underscoring the high stakes and urgent need for advanced air defense capabilities.
