The Yugoslav monitor Drava was a river monitor operated by the Royal Yugoslav Navy between 1921 and 1941. She was originally built for the Austro-Hungarian Navy as the name ship of the Enns-class river monitors. As SMS Enns, she was part of the Danube Flotilla during World War I, and fought against the Serbian and Romanian armies from Belgrade to the lower Danube. In October 1915, she was covering an amphibious assault on Belgrade when she was holed below the waterline by a direct hit, and had to be towed to Budapest for repairs. After brief service with the Hungarian People's Republic at the end of the war, she was transferred to the newly created Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), and renamed Drava. She remained in service throughout the interwar period, but was not always in full commission due to budget restrictions.
During the German-led Axis invasion of Yugoslavia in April 1941, Drava spent six days shelling airfields near Mohács in Hungary and fought off a small flotilla of Hungarian gunboats. On 12 April, she was attacked by Junkers Ju 87 Stuka dive bombers of the Luftwaffe. The anti-aircraft gunners on the ship claimed three enemy aircraft, but nine of the Stukas scored hits. Most of these had little effect, but the last bomb dropped straight down Drava's funnel and exploded in her engine room, killing 54 of the crew, including her captain, Aleksandar Berić. Only 13 of the crew survived. She was raised and scrapped by Hungary during their occupation of parts of Yugoslavia. Berić was posthumously awarded the Order of Karađorđe's Star for his sacrifice, and the base of the Serbian River Flotilla at Novi Sad is named after him.
