Soviet equipment losses during the German offensive came to 1,614 tanks and self-propelled guns destroyed or damaged of the 3,925 vehicles committed to the battle. Soviet losses were roughly three times those of the Germans. During Operation Kutuzov, 2,349 tanks and self-propelled guns were lost out of an initial strength of 2,308; a loss of over 100 percent. During Polkovodets Rumyantsev, 1,864 tanks and self-propelled guns were lost out of the 2,439 employed. The loss ratio suffered by the Soviets was roughly 5:1 in favour of the Germans. Large Soviet reserves of equipment and their high rate of tank production enabled the Soviet tank armies to quickly replace lost equipment and maintain their fighting strength. The Red Army repaired many of its damaged tanks; many Soviet tanks were rebuilt up to four times to keep them in the fight. Soviet tank strength went back up to 2,750 tanks by 3 August due to the repair of damaged vehicles. According to the historian Christer Bergström, Soviet Air Forces losses during the German offensive amounted to 677 aircraft on the northern flank and 439 on the southern flank. Total casualties are uncertain. Bergström's research indicates total Soviet air losses between 12 July and 18 August, during the German offensive and the Operation Kutuzov counteroffensive, were 1,104 aircraft. German losses In Soviet and German data, the human losses figures are not equivalent. In Soviet figures, both combat and non-combat losses (sick, desert, accident...) were
