List of ships of the Yugoslav Navy

A submariner's badge

The JRM maintained a submarine force throughout its existence. The first submarines to be commissioned were three submarines captured or returned after the Second World War. Starting with the 1950s and the Sutjeska-class Yugoslavia operated domestically built submarines. The Heroj-class marked a significant technological leap in Yugoslav shipbuilding capabilities with the Brodogradilište specijalnih objekata (Special objects shipyard) in Split becoming the shipyard where all of the remaining boats would eventually be built. All submarines with the exception of Mališan and the Heroj-class boats were named after rivers in Yugoslavia.[5][6]

The last class of Yugoslav submarines was the Una-clas midget submarines which, unlike their larger predecessor, did not carry any torpedo armament and were designed for covert special operations. A new class of larger submarines armed with torpedoes and anti-ship missiles, dubbed the Lora-class or Project B-73, was planned but wasn't started due to the subsequent Breakup of Yugoslavia. By 1991 the JRM operated eleven submarines homeported in the Lora Naval Base in Split. With the start of the Croatian War of Independence all except one Una-class were relocated to Montenegro where they were commissioned with the FR Yugoslav Navy.[5]

Kralj Petar Krešimir was laid down as Sergej Mašera, the first ship in a new class of missile boats that was to be built for the Yugoslav Navy just before the Breakup of Yugoslavia.

The JRM operated a large number of fast attack craft, commissioning both torpedo and missile boats of different origin. One of the first torpedo boats to enter service with the JRM after the war were eight American PT boats built by Higgins which received designations from MT1 to MT8. Starting with 1951 up to 1960, Yugoslav shipyards, mainly on the island of Korčula, constructed somewhere between 75 and 96 Higgins torpedo boats, with sources being conflicting regarding the exact number. In the early 1960s a number of them were converted to motor gun boats by removing the torpedo tubes. The last Higgins hulls were deleted by 1979. Improved relations with the Soviet Union from the 1960s made buying eastern military equipment once again possible; acquisition of ten Osa I-class missile boats started in 1965 becoming the first ships of the Yugoslav Navy to be armed with anti-ship missiles. Four Shershen-class torpedo boats were commissioned around the same time with ten additional boats being licence built at the Kraljevica Shipyard.[27][25][4]

The 1970s saw the introduction of six Končar-class missile boats featuring a mixture of Soviet and Swedish weaponry. At the time of the escalation of the Croatian War of Independence, the first ship of a new class of missile boats was being built at the Kraljevica Shipyard. Laid down as Sergej Mašera, the unfinished ship was captured by the Croatians, completed and entered service with the Croatian Navy as Kralj Petar Krešimir IV (RTOP-11).[4][28]

Cetina was laid down as Rab which was to become the second Silba-class ship built for the JRM.

The Yugoslav Partisans captured several landing craft during the last stages of the Second World War. Among them were two former Italian MZ-type craft which were deleted by 1979 and a single ex-German MFP. An unknown number of Siebel ferrys was also commissioned. During the 1950s Yugoslav shipyards built a large number of landing craft based on German war designs designating them as DTMs (Desantni Tenkonosac-Minopolagač, tank landing craft-minelayer), DSMs (Desantna Splav-Minopolagač, landing craft-minelayer) and PDSs (Pomoćna Desantna Splav, auxiliary landing craft). Several of these craft were captured by the Croatians, but only PDS-713, DSM-110 and DTM-110 were commissioned with the Croatian Navy, with the fate of the remaining ones left over in Croatian, unknown.[30][13]

During the 1970s and 1980s the "Montmontaža Greben Shipyard" on the island of Korčula built a large number of Type 11 and Type 22 landing-assault craft intended for transporting troops and cargo. Although sharing a common design, the two types featured a different carrying capacity, propulsion system and weapons. The last class of landing ships to be commissioned with the Yugoslav Navy was the Silba-class landing ship-minelayers. At the start of the Croatian War of Independence one ship was in active service while another one was being built. Named Rab, the unfinished ship was captured by the Croatians, completed and commissioned with the Croatian Navy as Cetina (DBM-81).[17][40][13]
