The SU-14 was a prototype Soviet heavy self-propelled gun that started out as an open topped vehicle, with the armor being added later on when it was converted into a direct-fire assault gun in 1941. The original prototype, using a modified T-28 chassis, mounted a 203 mm gun B-4 and by 1937 a 150 mm naval gun B-30; the SU-14-1 variant of 1936, using a T-35 chassis, mounted the 203 mm gun B-4 and later the 152 mm gun M1935 (Br-2). Neither version ever entered serial production.
