On 1 June 1941, the Red Army had 10,268 T-26 light tanks of all models on their inventories, including armoured combat vehicles based on the T-26 chassis.
As the war progressed and Germany's lighter tanks were replaced by the Panzer III, Panzer IV and heavier tanks, such as the Panther, the T-26 was gradually replaced through attrition by the vastly superior T-34.
