Ship project history: Design of I. G. Bubnov. Single-hulled, without watertight bulkheads. Okun ` and Makrel ` under original project should have 3 petrol motors for surface trim, but because of their absence completion was delayed. Finally diesels working with electric motors on one shaft were installed. Kasatka, Nalim, Skat and Graf Sheremetev were completed under original project.
Modernizations: 1906, Kasatka, Nalim, Skat, Feldmarshal Graf Sheremetev: 2 shafts were removed, new power plant consisted of 1 diesel / 1 electric motor (120 / 100hp, 9/5kts, 2.6t of diesel oil), large bridge amidships was fitted.
