Soviet destroyer Rastoropny (1938)

Rastoropny was one of 29 s (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 kn destroyer leaders, the Soviet Navy sought Italian assistance in designing smaller and cheaper destroyers. They licensed the plans for the and, in modifying it for their purposes, overloaded a design that was already somewhat marginally stable.

The Gnevnys had an overall length of 112.8 m, a beam of 10.2 m, and a draft of 4.8 m at deep load. The ships were significantly overweight, almost 200 MT heavier than designed, displacing 1612 MT at standard load and 2039 MT at deep load. Their crew numbered 197 officers and sailors in peacetime and 236 in wartime. The ships had a pair of geared steam turbines, each driving one propeller, rated to produce 48000 shp using steam from three water-tube boilers which was intended to give them a maximum speed of 37 kn. 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. Rastoropny reached 38 kn during her trials in 1940. Variations in fuel oil capacity meant that the range of the Gnevnys varied between 1670 to 3145 nmi at 19 kn. Rastoropny herself demonstrated a range of 2970 nmi at that speed.

As built, the Gnevny-class ships mounted four 130 mm 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 mm 34-K AA guns in single mounts and a pair of 45 mm 21-K AA guns as well as two 12.7 mm DK or DShK machine guns. They carried six 533 mm 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 kn. The ships were equipped with two K-1 paravanes intended to destroy mines and a pair of depth-charge throwers.

Construction and service
Major components for the ship that became Rastoropny were laid down at Shipyard No. 198 (Andre Marti South) in Nikolayev on 27 February 1936 as yard number 312 and were then railed to Shipyard No. 199 at Komsomolsk-on-Amur, Siberia, for completion where the ship was laid down again on 5 November 1936. She was launched on 25 June 1938 and commissioned on 5 January 1940.
