Ship project history


Part of the 1911 Programme, designated for the Black Sea Fleet. Holland design (Type 31A), double hull type, diving limit 100m, diving time 1 minute. Unlike contemporary Russian submarines these were fitted with a crush diving tank, gravitionally filled ballast tanks and watertight bulkheads built in. Undoubtedly the best submarine type ever built for the Imperial Russian Navy. The original design provided 2 diesels 850bhp each and 16kts surface speed but these were not fitted because of the notorious shortage of diesels.

Modernizations


1916, Kashalot; 1917, Narval: - 8 - 450 TT (Drzewiecki); + 4 - 450 TT (Drzewiecki-Podgorny)

1917, Kit: - 1 x 1 - 57/40, 8 - 450 TT (Drzewiecki); + 1 x 1 - 75/48 Canet, 4 - 450 TT (Drzewiecki-Podgorny)

Naval service


Kit and Narval were captured 1/5/1918 by the Germans together with Kashalot and surrendered to the Allies in November 1918. Scuttled off Sevastopol to prevent capture by the advancing Reds.
