TheErsatz (Replacement) Triglav class consisted of fourdestroyers built for theAustro-Hungarian Navy during theFirst World War. Completed late in the war, they saw little action; three ships were seized by Italy and one by France as war reparations in 1920.

The loss of twoTátra-class destroyers in the1st Battle of Durazzo in 1915 caused the Austro-Hungarian Navy to begin construction of four improved versions of theTátras the following year namedTriglav,Lika,Dukla andUzsok.

TheErsatz Triglav-class ships were slightly longer than theTátras with anoverall length of 85.28 meters (279 ft 9 in), abeam of 7.8 meters (25 ft 7 in), and a maximumdraft of 3.2 meters (10 ft 6 in). Theydisplaced 880metric tons (870long tons) at normal load and 1,050 metric tons (1,030 long tons) atdeep load.^[1] The ships had a complement of 114 officers and enlisted men.^[2]

The destroyers were powered by twoAEG-Curtisssteam turbine sets, each driving a single 2.52-meter (8 ft 3 in) propeller using steam provided by sixYarrow boilers. Four of the boilers wereoil-fired while the remaining pair used coal, although oil was sprayed onto the coal to increase power. The turbines, designed to produce 20,650shaft horsepower (15,400 kW), were intended to give the ships a speed of 32.6knots (60.4 km/h; 37.5 mph).Dukla was the fastest ship of the class at 33.8 knots (62.6 km/h; 38.9 mph). The ships carried 142.7 metric tons (140 long tons) of oil and 108 metric tons (106 long tons) of coal which gave them a range of 500nautical miles (930 km; 580 mi) at full speed.^[2][3]

The main armament of theErsatz Triglav-class destroyers consisted of two 50-caliberŠkoda Works10-centimeter (3.9 in) K11 guns, one each fore and aft of thesuperstructure in single mounts. Theirsecondary armament consisted of four 45-caliber66-millimeter (2.6 in) K09 TAG (German:Torpedoboot-Abwehr Geschütz (anti-torpedo boat guns)). Two additional guns were placed onanti-aircraft mountings. They were also equipped with four 450-millimeter (17.7 in)torpedo tubes in two twin rotating mountings aft of thefunnels. Two spare torpedoes were stored on the main deck.^[3]

After the war, three vessels—Triglav,Lika, andUzsok—were ceded toItaly and one,Dukla, toFrance. The last vessels were scrapped in 1939.
