The June 1941 distribution was 60 G-5s in the Baltic Fleet, 92 in the Black Sea Fleet, 135 in the Pacific Fleet, and six in the Caspian. During the war, 73 were lost in action and another 31 became unserviceable. By 1945 the Baltic still had 24 while the Pacific retained 134 and the Caspian six. The unusually large Far Eastern concentration is interpreted as a hedge against Japanese action, especially an attack toward Vladivostok. A mass torpedo-boat response could threaten an approaching fleet despite the limitations of the individual boats.
