Ship project history: Design of I. G. Bubnov. Single-hulled, without watertight bulkheads, development of Akula. Under original project it was supposed to equip them with 2 diesels on 1140hp, that should ensure 19kts surface speed. However it was necessary to install diesels lifted from Amur flotilla gunboats.
Modernizations: None.
Naval service: Morzh was lost in Black Sea 11-15/5/1917 for unknown cause. Tyulen ` was withdrawn by Whites to Bizerte where she was broken up in mid-1930s. Nerpa entered service with Red Navy, but was stricken on technical condition.
