The Sava-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 62 m (203 ft 5 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 580 tonnes (570 long tons), and their crew consisted of 91 officers and enlisted men. The Sava-class ships were powered by two triple-expansion steam engines, each driving one shaft, using steam generated by two Yarrow boilers driving. The engines were rated at 1,750 indicated horsepower (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.
The main armament of the Sava-class river monitors was a pair of 120 mm (4.7 in)/L45 guns in a single turret forward of the conning tower and a pair 120 mm (4.7 in)/L10 howitzers in the rear turret. They also mounted a pair of 66 mm (2.6 in)/L26 anti-aircraft guns, two 47 mm (1.9 in)/L44 guns, and seven machine guns. The maximum range of her Škoda 120 mm (4.7 in)L/45 guns was 15 kilometres (9.3 mi). 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.
