The Enns-class river monitors were built for the Austro-Hungarian Navy during the mid-1910s. The two ships of the class were assigned to the Danube Flotilla and participated in World War I. The ships survived the war and were transferred to Romania and the newly created Kingdom of Serbs, Croats and Slovenes (later Yugoslavia) as reparations.

Description and construction

The ships had an overall length of 57.9 m (190 ft 0 in), a beam of 10.3 m (33 ft 10 in), and a normal draught of 1.3 m (4 ft 3 in). They displaced 540 tonnes (530 long tons), and their crew consisted of 95 officers and enlisted men.[1] The Enns-class ships were powered by two triple-expansion steam engines, each driving one shaft, using steam generated by two Yarrow boilers driving.[1] The engines were rated at 1,500–1,700 indicated horsepower (1,100–1,300 kW) and were designed to reach a top speed of 13.5 knots (25.0 km/h; 15.5 mph). They carried 75 long tons (76 t) of fuel oil.[2]

The main armament of the Enns-class river monitors was a pair of 120 mm (4.7 in)/L45[lower-alpha 1] guns in a single turret forward of the conning tower and three 120 mm (4.7 in)/L10 howitzers to the rear, in individual armored cupolas. They also mounted two individual 66 mm (2.6 in)/L50 BAG anti-aircraft guns, and six machine guns.[1] The maximum range of her Škoda 120 mm (4.7 in)L/45 guns was 15 kilometres (9.3 mi).[3] Her armour consisted of belt and bulkheads 40 mm (1.6 in) thick, deck armour 25 mm (0.98 in) thick, and her conning tower, gun turrets and cupolas were 50 mm (2.0 in) thick.[1]
