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 equipment, including Soviet anti-ship missiles and Swedish guns.

During the Croatian War of Independence one ship, Vlado Ćetković, was captured by Croatian forces while being overhauled. It was eventually commissioned with the Croatian Navy as Šibenik and is still in use. The remaining five ships were relocated to Montenegro, entering service with the new FR Yugoslav Navy, with three of them being decommissioned in the early 2000s. The last two ships of the class are planned to be modified as patrol boats for service with the Montenegrin Navy.

The Končar class was developed by the Brodarski institut (BI) from Zagreb. The six-strong class was built at the Tito's Kraljevica Shipyard from 1977 to 1979 with all six ships being named after People's Heroes of Yugoslavia. The ships measure 44.9 m (147 ft 4 in) in length, with a 8.4 m (27 ft 7 in) beam and 2.6 m (8 ft 6 in) draught. The hull, similar to the Swedish Spica class, is made of steel with an aluminium superstructure. Fully loaded they displace 271 t (267 long tons) and are manned by a crew of 30.

The class utilizes a CODAG engine configuration for propulsion. Mounted on four shafts, two MTU 16V 538 TB91 diesel engines are used for economical cruising while two RR Marine Proteus 52 M gas turbines are used for achieving high speeds. Cruising speed is 22 knots (41 km/h; 25 mph) while the maximum achievable speed is 38–40 knots (70–74 km/h; 44–46 mph). Travelling at a near maximum speed of 38 knots, the ships have a maximum range of 380–490 nautical miles (700–910 km; 440–560 mi). Powered by diesel engines only and travelling at a speed of 22–23 knots (41–43 km/h; 25–26 mph) they have a range of 780–870 nautical miles (1,440–1,610 km; 900–1,000 mi), with exact numbers varying from source to source. Endurance is between five and seven days.
