Soviet frigate Retivyy
Retivyy (, "Ardent") was a Project 1135 Burevestnik-class Guard Ship (, SKR) or Krivak-class frigate. With an armament based around the URPK-4 "Metel" anti-submarine missile system, the vessel served with the Pacific Fleet of the Soviet and Russian Navies. The ship was launched on 14 August 1976 by A.A. Zhdanov in Leningrad, the second of the class built by the shipyard. After joining the fleet, the vessel took part in the search for the crew of the crashed Lockheed P-3 Orion AF 586. In 1981, the vessel sailed as part of a task force along the  west coast of the United States to test and measure American defences. Decommissioned on 4 August 1995, the vessel was subsequently sold to a South Korean company to be broken up. Design. Designed by N.P. Sobolov, "Retivyy" was the twelfth Project 1135 Guard Ship (, SKR) to be launched, and the second from the shipyard of A.A. Zhdanov in Leningrad. The vessel is named for a Russian word which can be translated as "ardent". " Retivyy" served with the Soviet Navy, and the Russian Navy after the dissolution of the Soviet Union, as an anti-submarine frigate. The ship was designed to  create safe areas for friendly ballistic missile submarines close to the coast. Displacing standard and full load, "Retivyy" had an overall length of , with a beam of and a draught of . Power was provided by a combination of two M8K and two M62 gas turbines installed as a COGAG set named М7K, driving two fixed pitch screws, for a design speed of . Range was at , at , at and at . The ship had a complement of 192, including 23 officers. The ship was designed for anti-submarine warfare around four URPK-4 "Metel" missiles (NATO reporting name SS-N-14 'Silex ') mounted on the foredeck. The missiles were backed up by a pair of quadruple torpedo tubes and a pair of RBU-6000 "Smerch-2" anti-submarine rocket launchers mounted forward of the bridge. Defence against aircraft was provided by forty 4K33 OSA-MA (SA-N-4 'Gecko') surface to air missiles which were launched from two twin ZIF-122 launchers, one mounted forward and the other aft. Two twin AK-726 guns were mounted aft, along with two single 21 km guns on the superstructure. Mines were also carried, either eighteen IGDM-500 KSM, fourteen KAM, fourteen KB "Krab", ten "Serpey", four PMR-1, seven PMR-2, seven  MTPK-1, fourteen RM-1 or twelve UDM-2. The ship had a well-equipped sensor suite, including a single MR-310A "Angara-A" air/surface search radar, "Volga" navigation radar, "Don" navigation radar, MP-401S "Start-S" ESM radar system, "Nickel-KM" and "Kremniyy" IFF and ARP-50R radio direction finder. An extensive sonar complement was fitted, including MG-332 "Titan-2", MG-325 "Vega" and MGS-400K, along with two MG-7 "Braslet" anti-saboteur sonars and the MG-26 "Hosta" underwater communication system. The ship was also fitted with the PK-16 ship-borne decoy dispenser system. Service. "Retivyy" was laid down by A.A. Zhdanov in Leningrad on 12  June 1974, the second of the class to be ordered from the shipbuilder, and was given the yard number 712. Launched on 14 August 1976 and commissioned later that year on 28 December, the ship was accepted into the Pacific Fleet on 5 February 1977 as part of the 173th Brigade and operated in the Atlantic, Indian and Pacific Oceans. On 30 October 1978, the ship participated in the search for the crew of the Lockheed P-3 Orion AF 586 from VP-9 that had crashed off the coast of the Kamchatka Peninsula. In 1979 "Retivyy" participated in operations in the  Indian Ocean with and , along with Project 641 submarines "B-33" and "B-112". Shortly afterwards, alerted by submarine , the ship joined "Razumnyy", "Rezkiy" and the submarines and to search for a ballistic missile submarine of the United States Navy that the Soviet Navy detected crossing their anti-submarine barrier. The search took place between 22 and 34 March. The following year, between 25 August and 22 September, the vessel sailed with "Rezkiy" again, but this time as part of a task force led by the Project 1134B Berkut B vessel , from the Aleutian Islands south along the west coast of the  United States. The purpose of the voyage was to test and measure the US response. Later, "Retivyy" underwent anti-submarine training with "Razumnyy" in 1988. With the dissolution of the Soviet Union on 26 December 1991, the ship was transferred to the Russian Navy. Soon after, the ship was retired. Decommissioned on 4 August 1995, "Retivyy" was stricken on 3 September and sold to a South Korean company to be broken up.
