SAS President Pretorius was the third of three President-class Type 12 frigates built in the UK for the South African Navy during the 1960s. The ship spent most of her career training and made many visits to foreign ports in Africa, Western Europe and Australia.

Description

The President-class ships displaced 2,170 long tons (2,200 t) at standard load and 2,605 long tons (2,647 t) at deep load. They had an overall length of 370 feet (112.8 m), a beam of 41 feet (12.5 m) and a mean deep draught of 17 feet 6 inches (5.3 m).[1]: 238  The ships were powered by a pair of English Electric geared steam turbines, each driving one propeller shaft, using steam provided by two Babcock & Wilcox boilers. The turbines developed a total of 30,000 shaft horsepower (22,000 kW) which gave a maximum speed of 30 knots (56 km/h; 35 mph).[2]: 64  They carried 309 long tons (314 t) of fuel oil that gave them a range of 4,500 nautical miles (8,300 km; 5,200 mi) at 12 knots (22 km/h; 14 mph). Their crew numbered 14 officers and 200 ratings.[1]: 238 

The Presidents were armed with one twin-gun mount for QF 4.5-inch (114 mm) Mk V dual-purpose guns forward and one twin mount for 40-millimetre (1.6 in) Bofors anti-aircraft guns. For anti-submarine work, the ships were fitted with Type 162, 170, and 177M sonars for the pair of triple-barrelled Mk 10 Limbo anti-submarine mortars. They were equipped with a Type 293Q surface-search radar, Type 262 and 275 gunnery radars, Type 277Q height-finding radar and a Type 978 navigation radar.[1]: 220–22, 238
