Read previewRussia has tried to keep its very limited number of Su-57 fighter jets hidden from the war in Ukraine, fearing that a combat loss would be a blow to the aircraft's reputation, according to Western intelligence and aviation experts. AdvertisementThe aircraft first saw combat in Syria in 2018 and was delivered to the Russian military in 2020. Kremlin officials have claimed that the Su-57 has seen combat in Ukraine, although the evidence supporting the claims is extremely limited. A Russian Su-57 fighter jet makes a demonstration flight during the opening of the MAKS-2021 International Aviation and Space Salon in Zhukovsky outside Moscow on July 20, 2021. He said that the strike demonstrates that Ukraine has a "relatively mature low-cost long-range harassment capability" that it can use to strike military bases deep inside Russia.
