Operational Role in WWII
The B-4 was held under the direct command of the Stavka Strategic Reserve and was deployed only where its massive firepower was required.
- Winter War: Known as the “Karelia Sculptor” for its effectiveness against Finnish pillboxes on the Mannerheim Line.
- Urban Combat: Used for direct fire against German fortified buildings and bunkers, notably during the Battle of Berlinu in 1945.
- Loading Challenge: Due to the heavy 100 kg projectile, a special hoisting crane was often used to assist in loading the breech.
Key Innovation: The unique tracked carriage allowed the gun to be fired directly from the ground without a separate firing platform, a significant innovation for heavy artillery of that era.
