The Mornar class consisted of two large patrol boats[a] 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.
Description and construction
The Mornar class consisted of just two boats: Mornar (PBR-551) which was laid down in 1957, launched in 1958 and commissioned on 10 September 1959, followed by Borac (PBR-552) which was laid down in 1964 and launched and commissioned in 1965.[b] The class was based on the Udarnik (PBR-581), a French-built submarine chaser of the Le Fougueux-class, which was acquired by Yugoslavia in 1956.
The boats measured 53.3 m (174 ft 10 in) in length with a 7 m (23 ft 0 in) beam and a draught of 2 m (6 ft 7 in). Standard displacement measured 330 tonnes (320 long tons; 360 short tons) while fully loaded they displaced 430 tonnes (420 long tons; 470 short tons). Propulsion consisted of four SEMT Pielstick PA17V diesel engines powering two shafts for a total of power output of 3,250 hp (2,420 kW), enabling a speed of 20 knots (37 km/h; 23 mph) and range of 3,000 nmi (5,600 km; 3,500 mi) at 12 knots (22 km/h; 14 mph) or 2,000 nmi (3,700 km; 2,300 mi) at 15 knots (28 km/h; 17 mph).
Their original gun armament consisted of two 3"/50 caliber guns, two single-barrelled 40 mm (1.6 in) guns and two single-barrelled 20 mm (0.79 in) guns. Anti-submarine weapons consisted of two Mark 6 depth charge (DC) throwers and two Mark 9 DC racks. Both boats were modernized during 1970/73 at the "Sava Kovačević" Naval Repair Yard in Tivat; their 76 mm guns were removed and four five-barrelled Soviet-built RBU-1200 were installed along with a Tamir-11 sonar.
Service history
The boats enjoyed a long, albeit uneventful, career in the Yugoslav Navy and both were deleted in 1992.
