The Mornar class consisted of two large patrol boats built for the Yugoslav Navy (Serbo-Croatian: Jugoslavenska ratna mornarica – JRM) by the Tito's Shipyard in Kraljevica during the late 1950s and early 1960s. The boats were based on the Udarnik (PBR-581), a French-built Le Fougueux-class submarine chaser acquired in 1956. Both boats had an uneventful career and were deleted in 1992.
