The Yugoslav Navy (Serbo-Croatian: Југословенска ратна морнарица, Jugoslavenska ratna mornarica, lit. 'Yugoslav War Navy'), was the navy of Yugoslavia from 1945 to 1992. It was essentially a coastal defense force with the mission of preventing enemy landings along Yugoslavia's rugged 4,000-kilometer shoreline or coastal islands, and contesting an enemy blockade or control of the strategic Strait of Otranto.
