Soviet frigate Doblestnyy
Doblestnyy (, "Valiant") was a Project 1135 Burevestnik-class Large Anti-Submarine Ship (, BPK) or "Krivak"-class frigate. With an armament centred on four Metel (NATO reporting name SS-N-14 'Silex') missiles, the ship was launched on 22 February 1973 and joined the Northern Fleet of the Soviet Navy as a dedicated anti-submarine vessel. "Doblestnyy" was designated a Guard Ship (, SKR) from 28 July 1977 in response to a change in emphasis of the navy, and subsequently undertook visits to a number of African nations, including Angola and Ghana. Taken out of service to be repaired and upgraded  on 19 June 1991, a lack of funding meant that this was cancelled and instead the vessel was decommissioned. The vessel was sold to be broken up on 18 July 1995. Design and development. "Doblestnyy" was the fifth Project 1135 Burevestnik (, "Petrel") Large Anti-Submarine Ship (, BPK) laid down and the sixth one launched. Project 1135 was envisaged by the Soviet Navy as a less expensive complement to the Project 1134A "Berkut" A (NATO reporting name 'Kresta II') and Project 1134B "Berkut" B (NATO reporting name 'Kara') classes of anti-submarine warfare ships, designated Large Anti-Submarine Ship (, BPK). The  design was originally given to the TsKB-340 design bureau of Zelenodolsk, which had created the earlier Project 159 (NATO reporting name 'Petya') and Project 35 (NATO reporting name 'Mirka') classes. However, the expansion in the United States Navy ballistic missile submarine fleet and the introduction of longer-ranged and more accurate submarine-launched ballistic missiles led to a review of the project to deal with this new threat. The work was transferred to TsKB-53, a design bureau in Leningrad that produced a substantially larger and more capable design. Created by N. P. Sobolov, Project 1135 combined a powerful missile armament  with good seakeeping for a blue water role and shared the same BPK designation as the larger ships. This was amended to Guard Ship (, SKR) from 28 July 1977 to reflect the change in Soviet strategy of creating protected areas for friendly submarines close to the coast. NATO forces called the new class 'Krivak' class frigates. Displacing standard and full load, "Doblestnyy" was long overall, with a beam of and a draught of . Power was provided by two M7 power sets, each a combination of a DK59 and a M62 gas turbine linked in a COGAG arrangement and driving one  fixed-pitch propeller. Each set was capable of a maximum of . Design speed was and range was at . The ship's complement was 192, including 23 officers. The ship had a primary mission of anti-submarine warfare for which it was equipped with four URPK-3 "Metel" missiles (NATO reporting name SS-N-14 "Silex"), two quadruple torpedo tube mounts for torpedoes and a pair of RBU-6000 "Smerch-2" anti-submarine rocket launchers. Defence against aircraft was provided by forty 4K33 "OSA-M" (SA-N-4 'Gecko') surface-to-air missiles which were launched from two sets of ZIF-122 launchers, each capable of launching  two missiles. Two twin AK-726 guns were mounted aft and two single mounts for 21-KM guns were carried on the superstructure. Provision was made for carrying 18 mines. "Doblestnyy" had a well-equipped sensor suite, including a single MR-310A "Angara-A" air/surface search radar, "Volga" and "Don-2" navigation radars, MP-401S "Start-S" ESM radar system and "Spectrum-F" laser warning system. An extensive sonar complex was fitted, including MG-332 "Titan-2", which was mounted in a bow radome, and MG-325 "Vega". The latter was a towed-array sonar specifically developed for the class and had a range of up  to . The ship was also equipped with the PK-16 decoy-dispenser system. Construction and career. "Doblestnyy" was laid down by Zalyv Shipbuilding yard in Kerch on 30 November 1970, and was given the yard number 12. The vessel was named for a Russian word that can be translated valorous or valiant. Launched on 22 February 1973 and commissioned on 28 December that year, the ship was deployed to the Northern Fleet on 17 February 1973. To that end, "Doblestnyy" left Sevastopol and sailed to Severomorsk arriving during June 1974. The vessel became part of the 10th Anti-Submarine Brigade, transferring  to the 130th Brigade in December 1982. During this period, the ship served mainly in the region of the Arctic Ocean. On 11 May 1985, the vessel undertook operations further afield, initially in the Mediterranean Sea and then to Accra, Ghana, arriving on 2 June for a week. The ship returned to Africa between 1989 and 1990 to serve as part of the Soviet support for the MPLA in the Angolan Civil War. On 19 June 1991, the ship was removed from service and sent to be repaired. A lack of funding meant that this was cancelled and, on 3  July 1992, "Doblestnyy" was the first in the class to be decommissioned. The ship was disarmed and sold on 18 July 1995 to a firm in the United States to be broken up.
