The Galeb class were minelayers originally built as minesweepers for the Imperial German Navy between 1918 and 1919. In July 1921, the six unarmed vessels were purchased as "tugs" for the navy of the newly-created Kingdom of the Serbs, Croats and Slovenes (from 1929, the Kingdom of Yugoslavia). Re-armed with two Škoda 90 mm (3.5 in) L/45 guns and two machine guns, they could carry 24 naval mines. They all served until April 1941, when they were captured by the Italians during the World War II German-led Axis invasion of Yugoslavia. They were then put into service by the Regia Marina under new names. Five of the ships were lost or sunk during World War II, the remaining vessel was put into service by the Yugoslav Navy after the war, and was finally deleted in 1962.
