The Ersatz (Replacement) Triglav class consisted of four destroyers built for the Austro-Hungarian Navy during the First 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 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 Ersatz Triglav-class ships were slightly longer than the Tátras with an overall length of 85.28 meters (279ft 9in), a beam of 7.8 meters (25ft 7in), and a maximum draft of 3.2 meters (10ft 6in). They displaced880 metric tons (870 long tons) at normal load and 1,050 metric tons (1,030 long tons) at deep load.[1] The ships had a complement of 114 officers and enlisted men.[2]
The destroyers were powered by two AEG-Curtiss steam turbine sets, each driving a single 2.52-meter (8ft 3in) propeller using steam provided by six Yarrow boilers. Four of the boilers were oil-fired while the remaining pair used coal, although oil was sprayed onto the coal to increase power. The turbines, designed to produce 20,650 shaft horsepower (15,400kW), were intended to give the ships a speed of 32.6 knots (60.4km/h; 37.5mph). Dukla was the fastest ship of the class at 33.8 knots (62.6km/h; 38.9mph). 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 500 nautical miles (930km; 580mi) at full speed.[2][3]
The main armament of the Ersatz Triglav-class destroyers consisted of two 50-caliberŠkoda Works10-centimeter (3.9in) K11 guns, one each fore and aft of the superstructure in single mounts. Their secondary armament consisted of four 45-caliber 66-millimeter (2.6in) K09 TAG (German: Torpedoboot-Abwehr Geschütz (anti-torpedo boat guns)). Two additional guns were placed on anti-aircraft mountings. They were also equipped with four 450-millimeter (17.7in)torpedo tubes in two twin rotating mountings aft of the funnels. Two spare torpedoes were stored on the main deck.[3]
After the war, three vessels—Triglav, Lika, and Uzsok—were ceded to Italy and one, Dukla, to France. The last vessels were scrapped in 1939.

The Tátra class consisted of six destroyers built for the Austro-Hungarian Navy shortly before the First World War.
T3 was a sea-going torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 78 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm (2.6 in) guns, four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, escort and minesweeping tasks, anti-submarine operations and shore bombardment missions. In 1917 the suffixes of all Austro-Hungarian torpedo boats were removed, and thereafter she was referred to as 78. She was part of the escort force for the Austro-Hungarian dreadnought Szent István during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.
SMS Warasdiner was a destroyer launched in 1913 as Lung Tuan, intended for sale to China. She was taken over by the Austro-Hungarian Navy in 1914, renamed and rearmed. She served in World War I with the Austro-Hungarian Navy. Following the war, the ship was ceded to Italy and scrapped.
Renaudin was one of six Bisson-class destroyers built for the French Navy during the early 1910s. Completed in 1913, the ship was assigned to the 1st Naval Army in the Mediterranean Sea. During the First World War, she escorted the battle fleet during the Battle of Antivari in August 1914 and escorted multiple convoys to Montenegro for the rest of the year. Renaudin helped to sink a crippled Austro-Hungarian destroyer during the 1st Battle of Durazzo in late 1915 and protected the evacuation of the Royal Serbian Army from Durazzo, Albania, in February 1916. The ship was sunk by an Austro-Hungarian submarine the following month with the loss of 50 crewmen.
T7 was a sea-going torpedo boat operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 96 F, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1915–1916, she was armed with two 66 mm (2.6 in) guns and four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines.

The Ersatz Zenta class was a class of three planned light cruisers of the Austro-Hungarian Navy designed in the mid-1910s as part of a naval expansion program passed during a period of rising tensions in Europe. Several designs were proposed, including options for a so-called "yacht cruiser" that was to have been used by Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne. The design that was ultimately selected called for ships that were capable of speeds of at least 30 knots, with an armament of fourteen 12-centimeter (4.7 in) guns and a thin armored belt that was 20 millimeters (0.79 in) thick.
