The Navy of the Independent State of Croatia (, RMNDH), was the navy of the Independent State of Croatia (, NDH), an Axis puppet state controlled by the fascist "Ustaše" party. The NDH was created from parts of the Kingdom of Yugoslavia on 10 April 1941, four days after the World War II invasion of Yugoslavia by the Axis powers commenced. The RMNDH consisted of two commands, the Coast and Maritime Traffic Command, and the River and River Traffic Command, and had its headquarters in the NDH capital, Zagreb. The Coast and Maritime Traffic Command consisted of three naval commands along the Adriatic coast, which were each divided into a number of naval districts. The naval districts consisted mainly of naval and weather stations, and were only responsible for coast guard and customs duties. The River and River Traffic Command consisted of seven river stations, a naval infantry battalion, and a River Command Flotilla built around two former Yugoslav river monitors, which had been scuttled during the invasion but subsequently refloated.
