In the early 1970s the Royal Netherlands Navy developed a 'Standard' frigate design to replace the destroyers of the Holland and Friesland classes. The 'Standard' design would have anti-submarine (the Kortenaer class) and anti-aircraft (the Jacob van Heemskerck-class) variants with different armaments on a common hull design. The first eight Kortenaers were ordered in 1974, with four more ordered in 1976, although two were sold to Greece while being built, and replaced to two of the anti-aircraft variant.[3]
The Kortenaer's were 130.2 metres (427 ft 2 in) long overall and 121.8 metres (400 ft) between perpendiculars, with a beam) of 14.4 metres (47 ft 3 in) and a draft of 4.4 metres (14 ft 5 in).[3][4]Displacement was 3,000 long tons (3,050 t) standard and 3,785 long tons (3,846 t) full load.[3] The ship was powered by two 25,800 shaft horsepower (19,200 kW) Rolls-Royce Olympus TM 3B and two 4,900 shaft horsepower (3,700 kW) Rolls-Royce Tyne TM 1C gas turbines in a combined gas or gas (COGOG) arrangement, driving two propeller shafts. The Olympus engines gave a speed of 30 knots (35 mph; 56 km/h) and the Tyne cruise engines gave a speed of 20 knots (23 mph; 37 km/h).[3]
