"Russia's Aerial Crisis: Losses Mount as Fighter Jets Grounded"

Ukrainian anti-air crews claim to have downed 13 Russian aircraft, including 10 Su-34 fighter-bombers, amid Moscow's winter offensive. If Ukraine's figures are accurate, the Russian air force would have around 105 Su-34s remaining in service, but an unknown number may not be operational due to damage, lack of pilots, and required routine maintenance. The arrival of Western F-16 fighter jets in Ukraine is expected to increase strain on the Russian air force, impacting its ability to support ground operations.
