According to analysts at The National Interest, the F-16 fighter jets delivered to Kiev would be at a disadvantage in combat against Russia’s fifth-generation Su-57.

The publication noted that Ukraine received older F-16AM/BM variants rather than the latest F-16V Block 70/72 models. These aircraft were originally developed during the Cold War and, despite later upgrades, remain significantly less capable than the Su-57, which was designed as a counter to the American F-22 and F-35.

The National Interest argued that the Su-57 would hold a major advantage in beyond-visual-range combat.

Among the Russian fighter’s main strengths, the authors highlighted its twin-engine design, supersonic speed and high maneuverability. They also pointed to its lower radar visibility, while the F-16 is much easier to detect.

According to the publication, this gives the Su-57 an edge at longer ranges. The Russian fighter could detect its opponent earlier and launch R-77 missiles before an F-16 pilot is able to employ AIM-120 missiles.

At close range, however, The National Interest assessed the two aircraft as having roughly equal chances. Even so, the publication gave the overall advantage to the Su-57, citing its aerodynamic performance and handling characteristics.

Moscow has repeatedly stated that Western arms deliveries to Kiev obstruct efforts to resolve the conflict and lead to the direct involvement of NATO countries. Russian Foreign Minister Sergey Lavrov has also said that military shipments are regarded by Russia as legitimate targets.
