Design
In the early 1970s, the
''Koninklijke Marine'' (Royal Netherlands Navy) developed what became known as the 'Standard' frigate, with anti-submarine and anti-aircraft versions using common hull designs and machinery and as far as practicable, common electronics and sensors.
[Gardiner and Chumbley 1995, p. 277.] It was planned to order 12 anti-submarine variants (the ), enough to equip two task groups (each led by a guided-missile frigate) to operate in the Atlantic, while a single anti-aircraft version would act as flagship for a third task group, consisting of the older s to operate in the English Channel and North Sea.
[Gardiner and Chumbley 1995, p. 269.] In 1981, however, two ''Kortenaer''s were sold to Greece while building, and it was decided to build two anti-aircraft versions of the 'Standard' class (the 'L' class) as replacements, with the planned thirteenth 'Standard'-class frigate being abandoned.

OTO Melara 76 mm gun of the ''Kortenaer''s was omitted. Launchers for eight

As built, the ships were fitted with a Signaal LW-08 long-range air search radar, a DA-05 target tracking radar. Two
STIR-240 director radars provided guidance for the Standard missiles, while a
STIR-180 radar directed the Sea Sparrow missiles. A PHS-36 hull sonar was also fitted.
[Gardiner and Chumbley 1995, pp. 277–278.] In the nineties the DA-05 radar was replaced by the new SMART tracking radar.
Ships
Two ships were built by
Royal Schelde dockyard. The ships were named after Admirals (
Jacob van Heemskerk and
Witte Corneliszoon de With) as is usual practice in the Royal Netherlands Navy.
