She was launched on 24 September 1935 and commissioned on 29 September 1936 in the Baltic Fleet. During the 1942 campaign, the submarine was under the command of Captain Mokhov Nikolay Konstantinovich and took part in the Soviet submarine campaign on 1942 in Baltic Sea.

Loss
While returning home after the successful campaign of summer 1942, the submarine was sunk. The most likely cause of the sinking was an attack with depth charges made by Finnish minealyer Finnish minelayer Ruotsinsalmi
