Russia lost 43 Su-34 jets in Ukraine, about 140 remain, says intelligence

Ukraine's military intelligence reported that Russia has lost 43 Su-34 fighter-bombers since the start of the full-scale invasion, with approximately 140 of the aircraft remaining in service as of October 22, 2026. The Su-34 serves as a key strike aircraft for Russia, primarily launching guided bombs near the front lines. Seven additional aircraft were damaged, and intelligence officials noted the losses equate to roughly 2.5-3 years of production, given Russia's estimated annual output of 14-18 jets. Russia continues producing modernized Su-34M variants at a Novosibirsk plant, delivering 22 aircraft in the past year, though sanctions have complicated access to critical electronic components and technologies.
