Design and description

The Leytenant Ilin-class ships were designed as an improved version of the Derzky class.^[1] The ships normally displaced 1,360 metric tons (1,340 long tons) and 1,562–1,600 metric tons (1,537–1,575 long tons) at full load. They measured 98 meters (321 ft 6 in) long overall with a beam of 9.34 meters (30 ft 8 in), and a draft of 3.15 meters (10 ft 4 in). The Leytenant Ilins were propelled by two Brown-Boveri-Parsons steam turbines, each driving one propeller using steam from four Normand-Vulkan boilers at a working pressure of 17 standard atmospheres (1,723 kPa; 250 psi). 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).^[2] During their sea trials, they only reached 28.8–32 knots (53.3–59.3 km/h; 33.1–36.8 mph) from 28,000–30,666 shp (20,880–22,868 kW). The ships carried between 159–350 t (156–344 long tons) of fuel oil which gave 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 Leytenant Ilin-class ships were originally intended to have an armament of two 60-caliber 102 mm (four in) Pattern 1911 Obukhov guns, one gun each on the forecastle and stern, 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 in 1914; based on a battle between the destroyer Novik and two German destroyers in August 1915, they decided to exchange the rearmost torpedo mount for two more 102 mm guns on the stern while the ships were still under construction.^[1] All of these guns were on the centerline and interfered with each other's movements.^[4] Anti-aircraft defense was provided by a 40 mm (1.6 in) anti-aircraft (AA) gun in a single mount amidships. The Leytenant Ilins were completed with one triple torpedo mount between the forward funnels and two mounts aft of the rear funnel. The ships could carry 80 M1912 naval mines. They were also fitted with a Barr and Stroud rangefinder and two 60-centimeter (24 in) searchlights.^[2]
