Soviet destroyer Karl Marx

The Izyaslav-class ships were designed to serve as flotilla leaders for the {{ship|Russian destroyer|Novik||2}}-type destroyers.Verstyuk & Gordeyev, p. 65 The ships normally displaced {{convert|1390|LT|t|lk=on}}Apalkov, p. 48 and {{convert|1570|-|1590|LT|t}} at full load. They measured {{convert|107|m|ftin|sp=us}} long overall with a beam of {{convert|9.5|m|ftin|sp=us}}, and a draft of {{convert|4.1|m|ftin|sp=us}}. The Izyslavs were propelled by two steam turbines, each driving one propeller using steam from five Normand-Vulcan boilers. The turbines were designed to produce a total of {{convert|32700|shp|lk=on}} for an intended maximum speed of {{convert|35|kn||lk=on}}.Verstyuk & Gordeyev, p. 75 During the ships' sea trials, they only reached {{convert|31.7|-|31.8|kn}} despite outputs of {{cvt|34975|-|35700|shp}}. The ships carried enough fuel oil to give them an estimated range of {{convert|1880|nmi|lk=in}} at {{convert|21|kn|}}. Their crew numbered 150.

The Izyaslav-class ships were originally intended to have an armament of two single four-inch (102 mm) Pattern 1911 Obukhov guns, one each at the bow and stern, and a dozen {{convert|450|mm|1|sp=us|adj=on}} torpedo tubes in six double mounts. The Naval General Staff changed this to four triple mounts once they became available and then decided to remove a torpedo mount in exchange for another four-inch gun at the stern on 20 August 1915 while the ships were still under construction. Another gun was ordered to be added on the forecastle on 25 May 1916. Izyaslav was completed with this gun armament, but her sister ships had another gun added on the stern in April 1917.Verstyuk & Gordeyev, pp. 66–67 All of these guns were on the centerline and interfered with each other's movements.Breyer, p. 62 Anti-aircraft defense was provided by a {{convert|2.5|in|mm|adj=on}} Pattern 1916 anti-aircraft (AA) gun and a 76 mm air-defense gun M1914/15 AA gun, both in single mounts amidships. The Izyaslavs were completed with one triple torpedo mount between the forward funnels and two mounts aft of the rear funnel. They could carry 80 M1912 naval mines. They were also fitted with a Barr and Stroud rangefinder and two {{Convert|60|cm|in|sp=us|adj=on}} searchlights.

Ordered from Böcker and Lange's shipyard in Reval, Estonia, in the 1912 naval program, Izyaslav was active during the Russian Civil War, taking part in several engagements against British ships during the British campaign in the Baltic. The destroyer was renamed Karl Marx (Russian: Карл Маркс) in 1922. She played a small role in the Winter War with the Soviet Baltic Fleet when Germany invaded the Soviet Union in 1941 (Operation Barbarossa), and was sunk by German aircraft on 8 August 1941.Budzbon, Radziemski & Twardowski, p. 112
