Design

Razumnyy displaced 2,835 tonnes (2,790 long tons; 3,125 short tons) standard and 3,190 tonnes (3,140 long tons; 3,520 short tons) full load and was 123 m (404 ft) in length.[1] Power was provided by a combination of two 17,000 horsepower (13,000 kW) M8K and two 6,000 horsepower (4,500 kW) M62 gas turbines installed as a COGAG set named М7К for a design speed of 32 knots (59 km/h).[2]

The ship was designed for Anti-submarine warfare around four URPK-4 Metel missiles (NATO reporting name SS-N-14 'Silex'), backed up by 533 millimetres (21.0 in) torpedoes and a pair of RBU-6000 213 mm (8 in) anti-submarine rocket launchers.[3]

Service

Razumnyy was deployed to the Baltic Fleet on 15 November 1974 as part of the 128th Brigate, subsequently moving to the Pacific Fleet on 22 June 1975 to serve in 173rd Brigade.[4] The vessel was designated a Guard Ship (Сторожевой Корабль, SKR) from 28 July 1977.[5]

Razumnyy served mainly in the Indian and Pacific Oceans. In 1977, together with sister-ship Storozhevoy, Razumnyy undertook operations off the Kuril Islands and in the Sea of Okhotsk. 1978 saw operations with another sister-ship, Rezkiy, in the Sea of Okhotsk, Sea of Japan, and the Indian Ocean, tracking US Navy Virginia class cruiser Fox, and a visit to Aden. 1979 saw operations in the Indian Ocean with Retivyy and Rezkiy, along with Project 641 submarines B-33 and B-112.[4]

Admiral of the Fleet of the Soviet Union Sergey Gorshkov paid a visit to Razumnyy in 1983. On 21 May 1987, the ship was involved in tracking Virginia-class cruiser Arkansas in the Sea of Okhotsk and, in April 1988, anti-submarine operations with Retivyy in the seas off the Kamchatka Peninsula. Razumnyy was decommissioned on 16 March 1998.[4]
