Ukraine’s military says it hit some of Russia’s most advanced combat aircraft deep inside its territory, striking Su-57 stealth fighters and a Su-34 bomber in the Chelyabinsk region, roughly 1,700 kilometers (1,056 miles) from the Ukrainian border.
The strike took place on April 25, according to Ukraine’s General Staff, which did not disclose the method of attack or confirm the exact number of damaged aircraft. Officials said “several” Su-57 jets and one Su-34 were hit.
The Su-57 is Russia’s most advanced fighter jet and its only operational fifth-generation combat aircraft. Designed with stealth features, advanced avionics, and high-speed maneuverability, it is intended to compete with Western aircraft such as the US F-35.
