The naval warfare on the Eastern Front during the WW2 (Great Patriotic War) was the largest conflict involving the Soviet Navy and without doubt it was the greatest naval war ever faced by a socialist or communist nation. In five years of warfare (excluding preliminary conflicts like the Winter War), the Soviet Navy endured times of sacrifice and losses, fighting against a formidable foe and writing bloody and glorious pages of naval war history poorly known in the western world.
Decades after the end of the war, destruction and confidentiality of documents make numerous details still unknown, it is only after modern-day researches of authors that a number of false myths and wrong claims (committed by all sources, post-war) receive a neutral assessment.
Contrary to the popular western belief that the naval warfare played no real part in the war, the Soviet Navy engaged in specific operations in the different areas of competence of the Fleets (Baltic, Black Sea, Northern, Pacific, and other Flotillas).
During the decade before the war, the Soviet Navy initiated large programs of expansion with a number of warships entering service (including cruisers and destroyers): such plans not completed in time, and by the time of the Nazi invasion, the shipbuilding programs stalled or diverted to wartime emergency plans.
The Soviet leadership, wisely realized how the submarine warfare was a key of strategic success and despite all classes of warships increased in numbers, submarines received a peculiar attention (with over 200 submarines in 1941!).
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The Baltic Fleet was a priority for the Navy and its submarine force was significantly large by the time of Winter War and the German invasion in 1941. The short conflict with Finland gifted much-needed battle experience but there was little time to absorb the numerous lessons of the conflict: interestingly, while the imposed blockade to Finland was not effective, submarines could boast their first victories scored since the Civil War.
The first operations against Germans hampered by constant over-estimation of enemy anti-submarine forces (similarly to what happened to Pacific Fleet in 1945), and operations cut short by the bloody retreats to Leningrad.
Despite the high losses suffered by the first year of war and the subsequent Siege of Leningrad, the Navy correctly assessed submarines as the best offensive asset and they were dispatched during 1942 to sail out of the Gulf of Finland and harass German shipping lines (especially with hope to interdict the supply of iron ore from Sweden). Soviet submarines sunk some ships, and suffered own losses, but Germans were caught unprepared delaying or stopping some merchants: it can be argued that
these delays were the best result achieved by Soviet Baltic submarines, rather than the material losses inflicted.
The following year, Germans and Finnish forces focused in preventing a repetition of the Soviet submarine campaign, placing extensive barrages of mines and anti-submarines nets, effectively closing the Gulf of Finland.
Soviet submarines attempted to penetrate the fields and nets, but after losing some boats, the Navy decided to postpone operations.
When Finland abandoned the Axis, Soviet submarine could resume their operations in summer 1944 exploiting the same Finnish harbors and avoiding the mine barrages: thanks this (and German anti-submarine forces once again unprepared), the Soviet Navy lost only 2 submarines in the last two years of war. Interestingly, the Baltic Fleet made great efforts to finish a number of submarines despite the dire situation of the Siege of Leningrad, making their contribution for the final operations (particularly important was the minelayer submarine L-21 and the large “Katyusha” class submarines).
Victories were far more numerous, and even if they did not score the same strategic impact of Black Sea operations, included also
shocking losses as the sinking of large vessels Wilhelm Gustloff, General Steuben and Goya with massive German human casualties.
Baltic Fleet submarines also scored better results in terms of enemy
military warships compared to other Fleets: a single Type-39 (Elbing-class) fleet torpedo boat and two Type-35 torpedo boats sunk on mines laid by Soviet submarines.

SOURCES:
Work is an essentially based on the Russian site
Sovboat.ru and work of author Miroslav Morozov: these are the top modern and most updated sources of Soviet Submarine warfare in WW2. German site
historisches-marinearchiv.de is also a relatively good source.
Causes of many Soviet losses is better assessed only on such sites because of constant updates received in the last decades from the wreck-diving groups in Baltic, disproving many old claims and formulating new updated assessment. Significantly, there are many widespread claims of unreal victories by the Finnish Navy based on old ‘80s and ‘90s sources, nowadays refuted by modern analysis and direct evidence but still retained in certain American (and Finnish) literature.
Lists of Soviet successes and victories made in other sites (especially English literature) like Uboat.net and Wikipedia are
NOT good sources, including many mistakes generated by ‘90s works.Similar works and tables made on English-based sites (uboat.net and wikipedia) and older English literature are not updated and contain a number of mistakes.
