The Navy of the Independent State of Croatia, was the navy of the Independent State of Croatia, 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.

The Royal Navy, commonly known as the Royal Yugoslav Navy, was the naval warfare service branch of the Kingdom of Yugoslavia. It was brought into existence in 1921, and initially consisted of a few former Austro-Hungarian Navy vessels surrendered at the conclusion of World War I and transferred to the new nation state under the terms of the Treaty of Saint-Germain-en-Laye. The only modern sea-going warships transferred to the new state were twelve steam-powered torpedo boats, although it did receive four capable river monitors for use on the Danube and other large rivers. Significant new acquisitions began in 1926 with a former German light cruiser, followed by the commissioning of two motor torpedo boats (MTBs) and a small submarine flotilla over the next few years. When the name of the state was changed to Yugoslavia in 1929, the name of its navy was changed to reflect this. In the late 1920s, several of the original vessels were discarded.

These ships were armed with two 76 mm (3 in) guns. An additional five ships were completed for the KM in 1931 as the Malinska or Marjan class, and were armed with a single 66 mm (2.6 in). All of the completed ships could carry 24 to 39 naval mines. The remaining ships were never completed.

The entire class was reconstructed between 1900 and 1910, when they received two Yarrow boilers and a second funnel.
