Kursk class, Russian Destroyer Escort laid down 1924 (Engine 1942)
In 1942, the Kursk class underwent a partial (25%) reconstruction to modernize them and extend their service life. They got new engines, gun mounts, air and surface search radar, and an upgraded ASW suite. RF Naval Staff now consider them a modern, capable combatant.

Ships in Class:

- Yakutsk (BPK-02): Laid down January 1946 in Rostov-on-Don, completed December 1946.

Notes:
Built on the base of a torpedo cruiser / large destroyer hull, this vessel was constructed for operational testing of the 9K42-M6 "Groza" weapon system and associated antisubmarine gear. The Groza system featured two stabilized four-barrel antisubmarine mortar launchers located on the forecastle of the ship. The ship was designed to allow a helicopter to land on the aft deck, but this required the removal of the stern depth-charge racks or minelaying gear, and was not regularly done until 1948.

Kharkov also carried two different sizes of torpedoes: two triple 45cm torpedo launchers (one on each beam) and one quad 65cm torpedo launcher on the midline. The 45cm launchers fire short-ranged acoustic seeking torpedoes designed to target submerged submarines, and had no reloads; the 65cm torpedoes were intended for defense against surface ships, and had one reload per tube.

A second ship, the Yakutsk, was built in 1946, and the design was used as the basis of the Serdityi-class. Proigryvatel' acoustic decoys were fitted to Yakutsk, but Kharkov lacks the necessary fittings to use the system.

- Serioznyi

Notes:
1947 Refit: ship's machinery was replaced by a pair of more modern and compact steam turbines of 16500 Kw each, allowing the conversion of an unused former engine space to install more fuel tanks for increased range. The class's fire-control was modernized with the installation of a large electronics suite. Two quad-barreled 9K42-M6 Groza launchers were installed on the forecastle in semi-recessed mountings.

Proigryvatel' acoustic decoys can be towed at the cost of some depth charges or mines.

Notes:
1947 Refit: ship's machinery was replaced by more modern steam turbines. The main armament was also updated with new equipment built to stricter Russian specifications, with the old guns being returned Latvia for coastal defense purposes; the 37mm guns were re-sited to ease topweight, which became necessary due to the installation of a large electronics suite. Two quad-barreled 9K42-M6 Groza launchers were installed on the forecastle in semi-recessed mountings.
