Project history: Ordered under the 1912 Programme for the Baltic Fleet in the German Schichau Yd in spite of growing tensions between these Powers, simply because that yard was able to offer a price 25% lower than the Russian ones. The condition was raised however that these ships had to be assembled in Russia, so a Schichau subsidiary yard was founded in 1913 at Riga. The contract design provided 2 102mm/60, 12 450mm TT and this was changed in 1915 to 4 102mm, 6 450mm TT but finally one triple TT set was added. In June 1915 the yard was taken over by the Russian Government and Metal Wks were ordered to complete the 4 ships (Gogland, Grengamn, Kulm and Patras) in 1918 as Fleet Minesweepers armed with 5 102mm/60, 1 40mm AA, 6 450mm TT. The others were re-ordered to be built according to the Orfey class design. The Fleet Minesweepers, being 18% ready in February 1917, were subsequently cancelled with the others which had not been laid down by that date.
