203 mm havličeva M1931 je bila sovjetska težka havličeva 203 mm. Med drugo svetovno vojno je bila pod poveljstvom Stavinega strateškega rezervata. Nemški vojaki so ga vzdevek "Stalinov maček". Te puške so bile z uspehom uporabljene proti težkim nemškim fortifikacijam in v urbanem boju za drobljenje zaščitenih stavb in bunkerjev. To orožje je bilo uporabljeno do konca vojne v bitki za Berlin, kjer je Rdeča armada pripeljala te pištole na točki iz bližine, da bi razstrelila nemške fortifikacije s svojimi težkimi 203mm granatami. Spomladi leta 1944 je bilo za ustvarjanje samohodne variante S-51 uporabljeno tankovsko šasijo KV-1. Močan vzgon od eksplozije na gobcih je posadko vrgel s sedeža in poškodoval prenos, zato je bil odpovedan.

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 Berlin 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.
