The Yugoslav Navy (Serbo-Croatian : Jugoslavenska ratna mornarica; JRM) was the naval branch of the Yugoslav People's Army (Jugoslavenska narodna armija; JNA). Organized as a coastal defence force with the main task of preventing enemy landings on its long and indented coastline, the navy's inventory reflected its foreign relations as well as the growing capabilities of its domestic shipyards and scientific institutions. The period immediately after the end of the Second World War was marked by relying on equipment that was captured, salvaged or obtained from the Western Bloc through reparations or lend-lease programs. [1] [2] [3]
Improved relations with the Soviet Union after Stalin's death meant the acquisition of Eastern military equipment was once again possible. This was soon after realized with torpedo and missile boats of Soviet origin being commissioned with the JRM. The 1960s and 1970s marked the start of a period of reliance on indigenous designs. Domestic naval programs developed by the Brodarski Institut from Zagreb and built in Yugoslav Shipyards included submarines, frigates, patrol boats, missile boats as well as other support ships, with some of them being exported to other countries. [3] [4]
The JRM came to its de facto end in 1991 with the escalation of the Croatian War of Independence. The Navy was engaged in imposing a naval blockade of Croatia which culminated in November with the Battle of the Dalmatian Channels. Having lost the majority of its naval infrastructure which was located in the now independent Croatia, the fleet eventually retreated to Boka Kotorska, Montenegro where it was officially disbanded in early 1992 with the remaining ships being commissioned with the new Navy of the Federal Republic of Yugoslavia. The FR Yugoslav Navy included around 80% of the JRM pre-war fleet, with the remaining 20% being lost or captured by Croatian Forces. [3]
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-class 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 was not 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]

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 the eight American MT-class motor torpedo boats, 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] [24] [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]

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 ferries 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] [38] [13]

The Croatian Navy is a branch of the Croatian Armed Forces. It was formed in 1991 from what Croatian forces managed to capture from the Yugoslav Navy during the breakup of Yugoslavia and Croatian War of Independence. In addition to mobile coastal missile launchers, today it operates 30 vessels, divided into the Navy Flotilla for traditional naval duties, and the Croatian Coast Guard. Five missile boats form the Croatian fleet's main offensive capability.
Kralj Petar Krešimir IV is a Kralj-class missile boat in service with the Croatian Navy. It was laid down in 1990 at the Kraljevica Shipyard as the first ship in a new class being built for the Yugoslav Navy. As the Croatian War of Independence started gaining momentum, shipyard workers stalled the completion of the ship until the remaining Yugoslav forces retreated, preserving the ship for the Croatian Navy that was being formed.
The Yugoslav 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.
The Shershen class was the NATO reporting name for a class of torpedo boats built for the Soviet Navy and allies. The Soviet designation was Project 206 Shtorm.
The Heroj class was a class of diesel-electric attack submarines built for the Yugoslav Navy during the 1960s. The three strong class was the second generation of domestically built submarines, representing a significant improvement compared to the earlier Sutjeska class. Built at the Brodogradilište specijalnih objekata in Split, the new class featured a streamlined hull design and four bow facing torpedo tubes that could also be used for minelaying.
The Sava class was a class of diesel-electric attack submarines built for the Yugoslav Navy during the late 1970s and early 1980s. Developed by the Brodarski Institute (BI) from Zagreb, the two strong class was built by the Brodogradilište specijalnih objekata in Split. They were intended as a replacement for the aging Sutjeska-class submarines. Compared to the earlier Heroj class, the Sava class was longer with more powerful armament that consisted of six torpedo tubes that could also be used for minelaying.
Split was a Koni-class frigate in service with the Yugoslav Navy (JRM). Laid down and completed during the late 1970s as Sokol of the Soviet Navy, it was the fourth ship of a class that was being built by the Zelenodolsk Shipyard primarily for export to various friendly navies. The ship was acquired by the JRM in 1980 and commissioned as Split, becoming the second ship in JRM service to be named after the city of Split. It was soon followed by a second Koni-class hull, Koper (VPBR-32), commissioned in the JRM in 1982. Designated as a Large Patrol Boat by the JRM, Split's original armament consisting of naval guns, anti-submarine rocket launchers and anti-aircraft missiles was further improved by the addition of four P-20 anti-ship missiles, making it the most versatile ship in the JRM inventory at the time.
The Končar class is a class of six missile boats built for the Yugoslav Navy during the late 1970s at Tito's Shipyard Kraljevica, SR Croatia. The boats featured a mixture of Western and Eastern European equipment, including Soviet anti-ship missiles and Swedish guns.
The Kralj class is a class of two missile boats, one of which was on order for the SFR Yugoslav Navy and one of which, following the break-up of Yugoslavia, was built for the Croatian Navy. As of 2009 both vessels remain in service. It is an upgraded version of the Rade Končar missile boat class and is 8.5 metres (28 ft) longer. Kralj Petar Krešimir IV and its sister ship Kralj Dmitar Zvonimir are the only ships in their class. A potential third ship was under consideration in 1999, but the ship was never commissioned due to budget restraints.
The Mornar class consisted of two large patrol boats built for the Yugoslav Navy 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.
T1 was a seagoing torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 76 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm (2.6 in) guns and four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, escort and minesweeping tasks, anti-submarine operations and shore bombardment missions. In 1917 the suffixes of all Austro-Hungarian torpedo boats were removed, and thereafter she was referred to as 76. She was part of the escort force for the Austro-Hungarian dreadnought Szent István during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.
The Una-class submarine was a class of six midget submarines built for the Yugoslav Navy at the Brodogradilište specijalnih objekata during the 1980s. They were designed with the purpose of laying small minefields and transporting naval special forces, with or without their submersibles, in shallow waters that were inaccessible for larger submarines. Due to their mission profile that called for a small design as well as the need to stay undetected, they lacked torpedo armament and a generator for battery recharging.
Velebit was a modified Una-class midget submarine and the only submarine to see service with the Croatian Navy. It was built for the Yugoslav Navy during the 1980s where it was named Soča. At the outbreak of the Croatian War of Independence Soča was being overhauled in the Brodogradilište specijalnih objekata division of Brodosplit shipyard in Split, Croatia. Although stripped of all equipment, it was preserved from the retreating Yugoslav forces by the shipyard workers.
Šibenik is a Končar-class missile boat in service with the Croatian Navy. It was built for the Yugoslav Navy at the Kraljevica Shipyard in the 1970s as Vlado Ćetković (RTOP-402). In 1991 during the early stages of the Croatian War of Independence it was captured by Croatian forces while being overhauled at the "Velimir Škorpik" shipyard in Šibenik.
Šolta is a Mirna-class patrol boat in service with the Croatian Navy. Completed during the 1980s as Mukos (PČ-176), it was the sixth ship of a class that was being built for the Yugoslav Navy in the Kraljevica Shipyard.
The Silba class is a class of three landing ships, also used as minelayers, built for the Yugoslav (JRM) and Croatian Navy (HRM) during the 1980s and 1990s. The ships were built at the Brodogradilište specijalnih objekata shipyard in Split with slight differences in armament configuration between the last two ships. By the time the Croatian War of Independence started, one ship was in service with the JRM while another was being completed.
Mališan was a CB-class midget submarine that served in the Yugoslav Navy from 1953 to 1957. Laid down in 1943 by the Caproni company in Milan as CB-20, she was ordered by the Italian Regia Marina during World War II for harbour defence and anti-submarine warfare tasks, but she was incomplete at the time of the Italian surrender in September 1943.
The Albona class were mine warfare ships used by the Italian Regia Marina and Royal Yugoslav Navy. Fourteen ships were originally laid down between 1917 and 1918 for the Austro-Hungarian Navy as the MT.130 class. However, the end of World War I and the dissolution of Austria-Hungary left them incomplete until 1920, when three ships were finished for the Regia Marina. These ships were armed with two 76 mm (3 in) guns. An additional five ships were completed for the KM in 1931 as the Malinska or Marjan class, and were armed with a single 66 mm (2.6 in). All of the completed ships could carry 24 to 39 naval mines. The remaining ships were never completed.
Sava was a Flutto-class submarine in service with the Yugoslav Navy. Built by Cantieri Riuniti dell'Adriatico in Monfalcone during the Second World War, Sava was laid down and completed as Nautilo for service with the Italian Regia Marina.
The Kraljevica class was a class of large anti-submarine patrol boats built for the Yugoslav Navy 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 and the second from 1954 until 1957. Although similar in layout, boats of the second series featured a slightly larger displacement and more powerful machinery.
