Orfey class destroyer
Ofrey class destroyer plan. These ships, benefiting from the Russo-Japanese war experience, had double the main transverse bulkheads of pre-1904 Russian destroyers with 12 watertight sections (each with their own pumping systems) as well as individually compartmentalized boilers, hence all the funnels. The keel was made of doubled 6mm steel sheets set at angles to each other, creating a double hull of sorts. Lacking true armor, the conning tower/bridge was made of half-inch ordnance steel sheets to provide splinter and small arms protection. Interestingly, the topside radio room (one 2 kW transmitter and two receivers) and two 45-cm searchlights were fed by a separate 10kW Penta kerosene dynamo protected centrally, rather than the rest of the ship’s power which was provided by two 20 kW turbo generators.
