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.
