Shchuka-class submarine

On 23 January 1930, the USSR Revolutionary Military Council (Revvoensoviet) adapted a proposed submarine concept that were to "execute positioning service on closed theatres".

The conning tower had brass symbols as identifiers (Щ-XXX, where the XXX is the number).

However, the submarines of the Pacific Fleet did not suffer any losses to the Japanese due to the tranquil nature of the theatre (military operations commenced only in the autumn of 1945 when the Japanese fleet largely was defeated).

In all, 35 Shchuka-class submarines were lost, the vast majority during World War II.

For instance, the first submarine of the early 20th century Som class carried the name.
