Kraljevica-class patrol boat
From Wikipedia, the free encyclopedia
The Kraljevica class was a class of large anti-submarine patrol boats built for the Yugoslav Navy (Serbo-Croatian: Jugoslavenska ratna mornarica – JRM) during the 1950s. Built by the Tito's Shipyard in Kraljevica, the 24 boats of the class were built in two series, the first from 1951 until 1954 (PBR-501 – PBR-512) and the second from 1954 until 1957 (PBR-513 – PBR-524). Although similar in layout, boats of the second series featured a slightly larger displacement and more powerful machinery.

Boats of the first series were stricken from the JRM inventory in 1983–86 while the last of second series were stricken in 1986–90. A number of these boats were exported to countries of the Non-Aligned Movement: per two boats to Bangladesh and Sudan, six to Indonesia and a single boat to Ethiopia. These were retired during the 1980s with the last operational boats appearing to be two in Indonesian service which were placed in reserve in 1989.
