Zheleznyakov was one of eight Fidonisy-class destroyers built for the Imperial Russian Navy during World War I. She was originally named Korfu (Корфу) before she was renamed Petrovsky (Петровский) in 1925 and Zheleznyakov (Железняков) in 1939.

Design and description

The Fidonisy-class ships were designed as an improved version of the Derzky class with an additional 102-millimeter (4 in) gun. Korfu displaced 1,326 long tons (1,347 t) normal and 1,580 long tons (1,610 t) at full load with an overall length of 92.51 meters (303 ft 6 in), a beam of 9.05 meters (29 ft 8 in), and a draft of 3.2 meters (10 ft 6 in) at full load.^[1] She was propelled by two Parsons steam turbines, each driving one propeller, designed to produce a total of 29,000 shaft horsepower (22,000 kW) using steam from five 3-drum Thorneycroft boilers for an intended maximum speed of 33 knots (61 km/h; 38 mph). During her sea trials, the ship reached a speed of 30.9 knots (57.2 km/h; 35.6 mph). Korfu carried enough fuel oil to give her a range of 2,050 nautical miles (3,800 km; 2,360 mi) at 19 knots (35 km/h; 22 mph). Her crew numbered 136.^[2][3]

The Fidonisy-class ships mounted a main armament of four single 102 mm Pattern 1911 Obukhov guns, one on the forecastle and three aft; one of these latter guns was superfiring over the other two. Anti-aircraft defense for Korfu and her sisters that were completed after the war was provided by a single 76.2-millimeter (3 in) Lender gun on the stern, a 37-millimeter (1.5 in) Maxim cannon, and four 7.62-millimeter (0.3 in) M-1 machine guns. The destroyers mounted four triple 450-millimeter (17.7 in) torpedo tube mounts amidships with two reload torpedoes and could carry 80 M1908 naval mines. They were also fitted with a Barr and Stroud rangefinder and two 60-centimeter (24 in) searchlights.^[2]
