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: 1911, Makrel': 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.
1911, Okun': kerosine dynamo machines were replaced by 1 diesel (120/100hp)
1910s, Kasatka, Feldmarshal Graf Sheremetyev: + 1 x 1 - 7.6/94
1915, Nalim, Skat: + 1 x 1 - 47/40 Hotchkiss
Naval service: Skat and Nalim were scuttled by British-French troops off Sevastopol. Nalim was raised in 1932 and broken up. Keta 23.9.1924 was foundered by flood at Kronshtadt, later wreck was raised and broken up.
