The Ersatz (Replacement) Triglav class consisted of four destroyers built for the Austro-Hungarian Navy during the First World War.

The loss of two Tátra-class destroyers in the 1st Battle of Durazzo in 1915 caused the Austro-Hungarian Navy to begin construction of four improved versions of the Tátras the following year named Triglav, Lika, Dukla and Uzsok.

The turbines, designed to produce 20,650 shaft horsepower (15,400 kW), were intended to give the ships a speed of 32.6 knots (60.4 km/h; 37.5 mph).

[2][3] The main armament of the Ersatz Triglav-class destroyers consisted of two 50-caliber Škoda Works 10-centimeter (3.9 in) K11 guns, one each fore and aft of the superstructure in single mounts.

Their secondary armament consisted of four 45-caliber 66-millimeter (2.6 in) K09 TAG (German: Torpedoboot-Abwehr Geschütz (anti-torpedo boat guns)).
