Ognevoy-class destroyer

The specification (TTZ in Russian) for these ships was issued by the Naval staff in November 1937. The design work was done by Zhdanov Yard in Leningrad under the leadership of A. Yunovidova and approved by the government in 1939.

Hull strength was significantly increased and the hull was enlarged compared to the Project 7 ships. Longitudinal framing was used and hull plating was thicker than the Project 7 ships. Hull height was increased giving extra free board.

The machinery consisted of two boiler rooms and two engine rooms similar to the Project 7U destroyers but in less cramped spaces. Electricity generation capacity was increased to two 100 kW (130 hp) plants and two 50 kW (67 hp) plants. An alternative design Project 30A using super-heated high pressure machinery based on American designs was projected but not built.

The armament was housed in two enclosed splinter-proof and weatherproof turrets in 'A' and 'Y' positions. This was a significant advance over the open mountings used in the Project 7 ships. The B-2LM turrets were introduced in the Tashkent class and proven successful in service but had no anti-aircraft capability. Anti-aircraft armament comprised two 85 mm (3.3 in) guns in a twin mounting in 'X' position and six 37 mm (1.5 in) guns in single mountings. The ships also carried two sets of quadruple torpedo tubes and 50 mines.

The ships were fitted with air warning, surface search and gunnery control radars and sonar after the war.

24 ships were ordered in 1938–1940 but the programme was disrupted by the German invasion in 1941. The ships being built in Nikolayev were demolished before launch or evacuated incomplete while those built in other yards were suspended for the duration of the conflict. Some of the intact ships were completed after the war to a modified design (K for korrektirovany – corrected).

Ognevoy's hull was towed to Poti, Georgia; her turrets were salvaged from the wreck of the destroyer Tashkent.
