ww2dbaseThe 203 mm Howitzer M1931 (B-4) field guns were designed by Nikolai Nikititsch Magdesiew in 1931, and production began in 1932. These heavy howitzers were mounted on tracked carriages for towing. Although the firing rate of 1 round per minute was rather slow, they were used with success against German defensive fortifications as the Soviet forces advanced toward Berlin, Germany during the European War.During the design's production life, 871 examples were built.

In the final days of the war, B-4s were frequently used in the direct-fire role against German strongpoints in Berlin, becoming known as ‘Stalin’s sledgehammer’.
