Soviet frigate Poryvistyy
Poryvistyy (, "Impetuous") was a Project 1135 "Burevestnik" Guard Ship (, SKR) or Krivak-class frigate. Displacing full load, the vessel was armed with the "Rastrub-B" anti-submarine and anti-shipping missile system. Launched on 16 May 1981, the vessel joined the Pacific Fleet of the Soviet Navy. Over the next decade, exercises with the aircraft carrier and other members of the Soviet fleet took the ship to Hawaii to demonstrate the capacity of the country to field a blue water navy. Later, the escalating Iran–Iraq War led to the ship being transferred to escorting duties in  the Persian Gulf. Between 1987 and 1988, "Poryvistyy" successfully accompanied 67 merchant ships to safety. After the dissolution of the Soviet Union in 1991, the ship was transferred to the Russian Navy, but, during the following year, was placed in reserve. Decommissioned on 5 June 1994, the ship was sold to a sea club named "Vostok" to serve as a museum ship. It served in this role until it was damaged by a fire in 1997. Design and development. Designed by N.P. Sobolov, "Poryvistyy" was the twenty-first and final Project 1135 Guard Ship (, SKR) launched. The vessel is named  for a Russian word which can be translated impetuous. " Poryvistyy" 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. "Poryvistyy" displaced standard and full load. Length overall was , with a beam of and a draught of . Power was provided by a combination of two M3 and two M60 gas turbines installed as a COGAG set named М7, which enabled the ship to achieve a design speed of . Range was at , at  , at and at . The ship's complement was 192, including 23 officers. The ship was designed around a main armament of four URPK-5 "Rastrub B" missiles (NATO reporting name SS-N-14B ‘’Silex’') mounted on the foredeck, which provided both anti-submarine and anti-shipping capability. The missiles were backed up by a pair of quadruple torpedo tubes and a pair of RBU-6000 "Smerch-2" anti-submarine rocket launchers. 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. 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. Construction and career. "Poryvistyy" was laid down by Zalyv Shipbuilding yard in Kerch on 21 May 1980, the last of the class to be constructed by the shipbuilder, and was given the yard number 17. Launched on 16 May 1981 and commissioned on 29 December, having already been allocated to the Pacific Fleet on 9 February. To that end, on 17 October 1983, "Poryvistyy" left Sevastopol with the aircraft carrier and sailed to Vladivostok, arriving on 28 February the following year. En route, the vessels called  at Luanda, Angola, between 12 and 20 November, Maputo, Mozambique, between 1 and 9 December, Victoria, Seychelles, between 8 and 13 December and Madras, India, between 5 and 10 February. The vessel became part of the 173rd Brigade. 1985 saw "Poryvistyy" take part in a number of exercises in the Pacific Ocean with "Novorossiysk". Between 25 March and 17 April, the two ships joined a large contingent of other major vessels including the Project 1134A "Berkut A" and Project 1134B "Berkut B" , and for operational exercises near Hawaii. Soon afterwards, between 29 May and 16 June, the pair were again  together in the Sea of Japan undertaking anti-submarine drills. Later that year, between 13 and 18 August, the vessel accompanied "Tallinn" on a diplomatic mission to North Korea. The breadth of these operations were designed to demonstrate the Soviet ability to operate as a blue-water navy. On 6 May 1987, a Soviet tanker was attacked by gunboats of the Islamic Republic of Iran Navy, part of an escalation in the Iran–Iraq War that had been raging since 22 September 1980. The Soviet Union responded by sending a large naval force, including "Poryvistyy", which had at the time  just finished a visit to Colombo, Sri Lanka, to the Persian Gulf to escort merchant vessels. Operations continued into the following year, with a total of 67 merchant ships taken under the ship's umbrella and safely brought to port. The ship then returned to the Sea of Japan, revisiting North Korea between 14 and 18 August 1990. With the dissolution of the Soviet Union on 26 December 1991, the ship was transferred to the Russian Navy. The vessel was deemed superfluous to requirements and, on 8 May 1992, was placed in reserve, being decommissioned two years later on 5  June 1994. However, the ship was still in a good condition and so was sold to a sea club named "Vostok" on 25 November. "Poryvistyy" served as a museum ship until being damaged by fire on 20 March 1997.
