The Gnevny class (Russian: тип “Гневный”) were a group of 29 destroyers built for the Soviet Navy in the late 1930s.
In the early 1930s the Soviets felt able to restart construction of fleet destroyers and forty-eight ships were ordered under the Second Five-Year Plan.
Four surviving ships from the Pacific Fleet were transferred to the People's Liberation Army Navy and served as the Anshan-class destroyers.
They licensed the plans for the Folgore class and, in modifying it for their purposes, overloaded a design that was already somewhat marginally stable.
[4] The turbines, rated at 48,000 shp (36,000 kW), were intended to give the ships a speed of 37 knots (69 km/h; 43 mph).
Variations in fuel oil capacity meant that the range of the Gnevnys varied between 1,670 and 3,145 nautical miles (3,093 and 5,825 km; 1,922 and 3,619 mi) at 19 knots (35 km/h; 22 mph).
They were fitted with a set of Mars hydrophones for anti-submarine work, although it was useless at speeds over 3 knots (5.6 km/h; 3.5 mph).
It included a TsAS-2 mechanical analog computer that received information from a KDP2-4 gunnery director on the roof of the bridge which mounted a pair of DM-4 four-meter (13 ft 1 in) stereoscopic rangefinders.
Anti-aircraft fire control was strictly manual with only a DM-3 three-meter (9 ft 10 in) rangefinder to provide data to the guns.
