After the war Razumny was modernized between 1954 and 1957 and was briefly reclassified as a target ship in 1960 before she became an accommodation ship later that year. Again reclassified as a target ship in 1962, she was listed for disposal in 1963 and scrapped.
Having decided to build the large and expensive 40kn 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.[1]
The Gnevnys had an overall length of 112.8m (370.1feet), a beam of 10.2m (33.5feet), and a draft of 4.8m (15.7feet) at deep load. The ships were significantly overweight, almost 2000NaN0 heavier than designed, displacing 1612MT at standard load and 2039MT 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 48000shp using steam from three water-tube boilers which was intended to give them a maximum speed of .[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. Razumny reached during trials in 1957. Variations in fuel oil capacity meant that the range of the Gnevnys varied between 1670nmi3145nmi at . Razumny herself demonstrated a range of 2300nmi at that speed.[4]
As built, the Gnevny-class ships mounted four 130adj=onNaNadj=on 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 76.2sp=usNaNsp=us 34-K AA guns in single mounts and a pair of 45mm 21-K AA guns[5] as well as two 12.7mm DK or DShK machine guns. They carried six 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 .[6] The ships were equipped with two K-1 paravanes intended to destroy mines and a pair of depth-charge throwers.[7]
Major components for the ship that became Razumny were laid down at Shipyard No. 200 (named after 61 Communards) in Nikolayev on 7 July 1936 as yard number 1075 and were then railed to Vladivostok for completion at Shipyard No. 202 (Dalzavod) where the ship was laid down again on 16 August 1937 as Prochny. She was launched on 30 June 1939 and was renamed Razumny on 25 August before she was completed on 20 October 1941[8] and commissioned on 7 November into the Pacific Fleet.[9] As a result of the weakness of the Northern Fleet and the importance of the Arctic convoys of World War II, Stavka decided to transfer several modern ships from the Pacific to the Northern Fleet via the Northern Sea Route. Led by the destroyer leader, Razumny and her sister ships and departed Vladivostok on 15 July 1942, although Revnostny collided with a freighter on the 18th and had to return to Vladivostok. They stopped at Tiksi on 14 August for a few days, resumed the voyage five days later and arrived off Kola Bay on 14 October.[10]
Razumny and two other destroyers were sent to rescue the crew of her sister on 21 November after the ship had broken in half in a storm. Razumny only rescued one man because she was assigned to guard the other ships as they rescued the rest of the crew. On 25–27 December, the destroyer helped to escort Convoy JW 51A. In response to a radio intelligence report of a German convoy of two transports with a destroyer and two smaller escorts steaming east from Tromsø, Norway, Baku and Razumny made a night sortie on 20 January 1943. They engaged the German minelayer with the minesweepers M303 and M322, and subchasers UJ1104 and UJ1105 off Cape Makkaur. After closing the range, Baku fired four torpedoes at what the Soviets believed was the lead transport, all of which missed. As her lookouts reported explosions, the latter was believed sunk, and both Soviet warships turned their guns against what was believed to be the second transport, without result. The German vessels returned fire without damaging Baku, and the engagement ended after seven minutes when visibility deteriorated, allowing the Soviet ships to retreat behind a smokescreen laid by Razumny. She escorted a small convoy from the White Sea to Kola Bay on 3–4 February and began a refit on the 25th. While still in drydock on 3 April, the ship was struck by one bomb that penetrated through the entire ship before detonating next to the hull; another bomb exploded 1.5m (04.9feet) from the side of the ship. One crewman was killed and three were wounded; repairs were completed on 25 June.[11]
Razumny spent the next six months escorting local convoys, often between Murmansk and Arkhangelsk. She helped to escort Convoy JW 54A on 24–25 November and Convoy JW 55B on 28–30 December. The ship and three other destroyers made an unsuccessful attempt to intercept German supply ships off the Norwegian coast on 20–22 January 1944. Razumny was one of the escorts for Convoy JW 56A on 27–29 January and she spent most of the next year escorting Allied convoys, notably Convoys JW 57, JW 58, JW 59, JW 60, JW 61, RA 61, JW 62 and JW 63 as well as local ones. During the Petsamo–Kirkenes Offensive, Razumny bombarded the Norwegian town of Vardø on 26 October. Norwegian fishing boat Spurven was sunk at Vardo. Her last escort mission was on 20 January 1945.[12]
After the war, the ship had a lengthy modernization from 1954 to 30 June 1957. She stricken from the Navy List and redesignated as target ship TsL-29 on 6 February 1960 and reclassified as accommodation ship PKZ-3 on 15 September. Although the ship was listed for disposal on 4 July 1960, she was converted into target ship SM-14 on 23 October 1962. The hulk was discarded on 4 May 1963 and subsequently scrapped over the next year.[9]
