 Russia has lost 140,460 troops in Ukraine. The General Staff of Ukraine's Armed Forces reported that Russia had lost 140,460 troops in Ukraine since the beginning of its full-scale invasion on February 24, 2022. According to the report, Russia has also lost 3,296 tanks, 6,517 armoured fighting vehicles, 5,167 vehicles and fuel tanks, 2,306 artillery systems, 466 multiple launch rocket systems, 239 air defence systems, 298 airplanes, 287 helicopters, 2,012 drones and 18 boats. While the Red Stars on the aircraft of the Russian Aerospace Force have not been very visible in recent months, Russia's air force remains largely intact despite its grinding war in Ukraine according to independent analysis and official comments. The abundance of Russian aircraft hasn't resulted in the Kremlin dominating the skies over Ukraine. Ukraine has been able to hold Russian aircraft at risk with ground-based air defences, including new western systems, legacy Soviet-era kit and man-portable air defences. Analysis and foreign military officials have frequently noted Ukraine's skillful employment of air defence systems. To minimise risk, Russia has resorted to launching long-range missile attacks from bombers in Russian airspace and mounting attacks on Ukrainian cities and infrastructure with relatively cheap Iranian-made drones putting additional strain on Ukraine's air defences. Russia in 2022 lost some 6-8% of its active tactical combat aircraft inventory, but overall, fleet size somewhat masks the loss to some individual types, including reductions reaching 10-15% for some pre-war active multi-role and ground attack aircraft fleets. Besides, Russia's army is estimated to have lost nearly 40% of its pre-war fleet of tanks in Ukraine.
