Project history: Ordered in December 1906 as a Bubnov's version of the 400t Lake type submarines (Kaiman class). In many respects she represented the enlarged Minoga design with a more reliable powerplant. She experienced serious teething problems, the most troublesome being replacement of 225hp electric motor by a 300hp one and triple changing of propellers. She was a single bull type with saddle tanks. Undoubtedly the most successful of the pre-war Russian submarines, she near missed the German coastal battleship Beowulf.
