WW2: U-boats losses caused by Soviet Armed Forces

U-9 as the Soviet trophy
Трофейная подлодка Ю-9 в доке

Kriegsmarine was (in)famous for the massive use of their submarine's fleet during the War, despite most of the U-boats were used against Allied shipping, some were deployed against the Soviet Navy. That's the list of the Soviet anti-submarines successes.

NOTE: this list include also U-boats lightly damaged in action. This kind of damage was often a success because could force the submarine to abandon a patrol.

A submarine with the holed periscope can’t attack a merchant after all! Many merchants were potentially saved attacks that caused this kind of damage.

2 U-boats surely sunk by Soviet forces (one by submarine, one by depth charges) with other 4 of uncertain loss. At least 3 U-boats suffered soviet attacks with heavy damages as result (caused by depth charges and ramming) and needed time to be repaired.

In Arctic, the Soviets made successful use of Allied Lend-Leased ships (destroyers and minesweepers) and aircrafts (Catalina and B-25 Mitchell), against German U-boats.

BLACK SEA: 2 Submarines directly sunk in action: an Italian midget submarine by motor torpedo boat and an U-boat by air attack. 2 other U-boats were badly damaged and scuttled by Germans as direct consequence of the damage, other 2 Italian midget submarines were technically in bad conditions at the time of the aerial attack resulting in heavy damages and were captured some time later. Only one time a German U-boat suffered heavy damages by depth charges, in another occasion 2 Italian midget submarines suffered bad damages and were out of action by the time of the blockade of Sevastopol.

In Black Sea a number of Submarine attacks close Poti were prevented by ASW even if the U-boats were not damaged.

BALTIC SEA: 6 German U-boats were directly sunk: one by submarine, one by depth charges, 2 by mines, one by mines laid by submarine, one by ground artillery fire. Another U-boat was badly damaged and scuttled by Germans as direct consequence of the damage.

Alongside this higher successes in Baltic Sea, the Germans caused only limited damages to the Soviet forces because their victim were mostly small boats or submarine chasers, rather than merchants or tankers.
