The T-34 shielded was one of the projects to improve the armor of the T-34 series tanks. This variant of shielding was developed by the engineers of Research Institute-48 and Plant No. 112 under the supervision of I. Burtsev. During field trials, the armored screen sides were able to withstand fire from 37 mm and 50 mm anti-tank guns, but were penetrated by 88 mm and 75 mm armor-piercing shells. All manufactured prototypes were sent to the front and lost in battle.
