T-35: The Five-Turret Soviet Land Battleship

The T-35 took the multi-turret tank concept to its logical extreme: five turrets arranged on a single hull. The main turret mounted a 76.2mm cannon, two secondary turrets carried 45mm guns, and two machine gun turrets rounded out the armament. Weighing 45 tons and stretching 9.7 meters long, the T-35 was the only five-turret tank to enter serial production anywhere in the world. Its silhouette was so distinctive it appeared on Soviet propaganda posters and medals.

Around 61 T-35s were built between 1933 and 1939. On parade, they looked magnificent, a rolling fortress bristling with guns. In combat, they were disasters. The T-35 was mechanically unreliable, breaking down constantly due to the strain its massive weight placed on an overloaded drivetrain. The five turrets couldn't effectively coordinate fire against a single target. The armor, at 30mm maximum, was inadequate by 1941 standards. Most T-35s deployed during Operation Barbarossa were lost not to enemy fire but to mechanical failures, their crews abandoned them on roadsides after breakdowns. Nearly all were destroyed in the first weeks of the war.
