Körös-class river monitor

The Körös class consisted of two river monitors built for the Austro-Hungarian Navy during the 1890s. They both served during World War I and were allocated to the Kingdom of Yugoslavia after the war by the Allies. Szamos was disarmed and sold into civilian service in 1921 while Körös was renamed Morava and retained by the Royal Yugoslav Navy. The ship saw combat during the Invasion of Yugoslavia by the Axis powers in 1941 during World War II, but was ultimately scuttled by her crew to prevent her capture.
