Russian destroyer Orfey

Orfey (Russian: Орфей) was the lead ship of her class of eight destroyers built for the Imperial Russian Navy during World War I. Completed in 1916, she served with the Baltic Fleet, but suffered turbine damage in late 1917, and was laid up for the rest of the war. The ship was not repaired by the Soviets and was scrapped in 1931.

Design and description

The Orfey-class ships were designed as an improved version of the Derzky class.^[1] Orfey normally displaced 1,260 long tons (1,280 t) and 1,540 long tons (1,560 t) at full load. She measured 98 meters (321 ft 6 in) long overall with a beam of 9.3 meters (30 ft 6 in), and a draft of 2.98 meters (9 ft 9 in). The Orfeys were propelled by two Curtiss-AEG-Vulcan steam turbines, each driving one propeller using steam from four Normand-Vulcan boilers. The turbines were designed to produce a total of 30,000 shaft horsepower (22,000 kW) for an intended maximum speed of 35 knots (65 km/h; 40 mph) using forced draft.^[2] On Orfey's sea trials, she only reached 31.4 knots (58.2 km/h; 36.1 mph). The ships carried enough fuel oil to give them a range of 1,680 nautical miles (3,110 km; 1,930 mi) at 21 knots (39 km/h; 24 mph). Their crew numbered 150.^[3]

The Orfey-class ships were originally intended to have an armament of two single four-inch (102 mm) Pattern 1911 Obukhov guns and a dozen 450-millimeter (17.7 in) torpedo tubes in six double mounts. The Naval General Staff changed this to four triple mounts once they became available and then decided to exchange a torpedo mount for two more four-inch guns in August 1915 while the ships were still under construction. One of these guns was mounted on the forecastle and three on the stern, aft of the torpedo tubes.^[1] The Orfeys were completed with one triple torpedo mount between the forward funnels and two mounts aft of the rear funnel. They could carry 80 M1912 naval mines. They were also fitted with a Barr and Stroud rangefinder and two 60-centimeter (24 in) searchlights.^[2]
