The Navy of the Kingdom of Serbs, Croats and Slovenes – from 1929, the Royal Yugoslav Navy (Serbo-Croatian Latin: Kraljevska mornarica; Serbo-Croatian Cyrillic: Краљевска морнарица; КМ) – included a wide range of vessels during its existence from 1920 to 1945. This list includes all sea-going warships ranging from a light cruiser down to motor torpedo boats (MTBs), and also includes river monitors that operated on the Danube and other rivers. Large auxiliary vessels such as submarine tenders and tankers are included, but hulks, tugs and smaller auxiliary craft are not.
