Soviet destroyer Rezvy (1937)

Rezvy was one of 29 Gnevny-class destroyers (officially known as Project 7) built for the Soviet Navy during the late 1930s. Completed in 1940, she was assigned to the Pacific Fleet.

Design and description

Having decided to build the large and expensive 40-knot (74 km/h; 46 mph) Leningrad-class destroyer leaders, the Soviet Navy sought Italian assistance in designing smaller and cheaper destroyers. They licensed the plans for the Folgore class and, in modifying it for their purposes, overloaded a design that was already somewhat marginally stable.[1]

The Gnevnys had an overall length of 112.8 meters (370 ft 1 in), a beam of 10.2 meters (33 ft 6 in), and a draft of 4.8 meters (15 ft 9 in) at deep load. The ships were significantly overweight, almost 200 metric tons (197 long tons) heavier than designed, displacing 1,612 metric tons (1,587 long tons) at standard load and 2,039 metric tons (2,007 long tons) at deep load. Their crew numbered 197 officers and sailors in peacetime and 236 in wartime.[2] The ships had a pair of geared steam turbines, each driving one propeller, rated to produce 48,000 shaft horsepower (36,000 kW) using steam from three water-tube boilers which was intended to give them a maximum speed of 37 knots (69 km/h; 43 mph).[3] The designers had been conservative in rating the turbines and many, but not all, of the ships handily exceeded their designed speed during their sea trials. Others fell considerably short of it, although specific figures for most individual ships have not survived. Variations in fuel oil capacity meant that the range of the Gnevnys varied between 1,670 to 3,145 nautical miles (3,093 to 5,825 km; 1,922 to 3,619 mi) at 19 knots (35 km/h; 22 mph).[4]

As built, the Gnevny-class ships mounted four 130-millimeter (5.1 in) B-13 guns in two pairs of superfiring single mounts fore and aft of the superstructure. Anti-aircraft defense was provided by a pair of 76.2-millimeter (3 in) 34-K AA guns in single mounts and a pair of 45-millimeter (1.8 in) 21-K AA guns[5] as well as two 12.7-millimeter (0.50 in) DK or DShK machine guns. They carried six 533 mm (21.0 in) torpedo tubes in two rotating triple mounts; each tube was provided with a reload. The ships could also carry a maximum of either 60 or 95 mines and 25 depth charges. They were fitted with a set of Mars hydrophones for anti-submarine work, although they were useless at speeds over 3 knots (5.6 km/h; 3.5 mph).[6] The ships were equipped with two K-1 paravanes intended to destroy mines and a pair of depth-charge throwers.[7]

Construction and service

Major components for the ship that became Rezvy were laid down at Shipyard No. 198 (Andre Marti South) in Nikolayev on 5 November 1935 as yard number 228 and were then railed to Vladivostok for completion at Shipyard No. 202 (Dalzavod) where the ship was laid down again on 23 August 1936. She was launched on 24 September 1937 and commissioned on 24 January 1940.[8]
