The Jacob van Heemskerck-class frigate was a class of frigates of the Royal Netherlands Navy. They were designed to be an air defence version of the Kortenaer class. The helicopter was replaced by a Standard medium range surface-to-air missile (SAM) system and associated radars. Two ships were built for the Royal Netherlands Navy. In 2005 they were sold to the Chilean Navy.
