The Skoryy class were the first destroyers built for the Soviet Navy after World War II. The Soviet designation was Project 30bis. The ships were derived from the Project 30 Ognevoy-class destroyer, but were slightly larger with better sea-keeping and significantly increased endurance. These ships were longitudinally framed and completely welded. The ships were built in 101 modular pre-fabricated sections which led to rapid building times.

Their general design also remained very classical, with benches of torpedo tubes distributed between the two chimneys and the quarter deck, a more modern double turret artillery, and a powerful AA battery, according to the standards imposed in 1944-45. The machinery and main armament was essentially identical to those of the Ognevoy class destroyers but the boilers employed forced draught for increased power.

In total 70 ships seems to have been built between 1949 and 1953. This was the largest operational Soviet destroyer class ever, answering the Gearing class. These ships served on the four fleets (Baltic, Arctic, Black Sea and Far East) until the end of the Cold War.

Project 31 was an improved Skoryy class destroyer. Only there were only eight ships modernized EM pr.30 bis of the Soviet Navy, converted in 1957-1962.

The assignment for Project 31 was developed by the USSR Navy in 1957, the purpose of the work was to "convert the destroyers of project 30bis into electronic intelligence ships". The technical project for the conversion of these ships was developed in 1957 by TsKB-57.

In the course of the work, only the main caliber artillery was left unchanged from the ship's armament. The former main power plant remained unchanged. The bow torpedo tube, aft anti-submarine bombers BMB-1, as well as all 85-mm and 37-mm artillery were removed. Instead, five new, for the first time used single-barreled 57-mm machine guns of the ZIF-71 type, with a rate of fire of 170-200 rounds per minute (3500 rounds of ammunition) with a remote guidance system D-71-2 were installed.

The anti-submarine armament included one rotary five-tube 533-mm torpedo tube PTA-53-31, adapted for firing anti-submarine torpedoes, with a powder firing system and a Zvuk-31 system, as well as jet-bomb armament: two 16-barrel 212-mm rocket stabilized bomb launchers RBU-2500 with the Smerch-31 PUSB system (96 RGB-25 unguided depth charges). There were also 14 BB-1 depth charges in the aft sub-deck bomb throwers. In order to protect against attacking torpedoes, the ship was equipped with two towed BOKA acoustic guardians.

The radio-technical armament of the project 31 ship was represented by one Fut-N radar for detecting air and surface targets(on the mainmast), one Zalp-M2 radar for controlling artillery firing of the main caliber artillery (on the foremast) and two Fut-B radars for controlling anti-aircraft artillery fire (side by side on the aft superstructure). There was one Don navigation radar with a Palma block, Fire-50 IR equipment for joint navigation, and standard for destroyers IFF (Nickel-K and Chrome-K). Instead of the previous one, a new sonar station GS-572 (Hercules) was installed.

Project 31 became the first ship of the Soviet Navy to have standard radio intelligence equipment installed, designed to search for and intercept working radio stations in the VHF, HF, CB and L wave bands.

Destroyer Bezboyaznenny laid down by Project 30bis on 26 March 1951 at the Shipyard named after 61 kommunara, Nikolaev (yard No.1114), launched on 31 August 1951, commissioned on 11 January 1952 and 06 July 1952 was assigned to the Black Sea Fleet.

The ship was upgraded at the Shipyard named after 61 kommunara, Nikolaev according to Project 31 from 01 July 1958 to 25 November 1960.

From 13 August 1976 - SM-274 target ship.

On 12 August 1977 the ship was excluded from the lists of the Black Sea Fleet and scrapped.
