Outstanding platforms with excellent self-defence capability and powerful air defence. High degree of automation, resulting in a small crewsize. The combat systems suite is characterised by a highly modern AAW suite, based on the APAR and SMART-L combination. This provides a multi-layer Area Air Defence capability at the Task Force level against saturation attacks. The ships will replace the Tromp and Jacob van Heemskerck Class. The first two ships will be tasked as command ship with extensive communications equipment fitted. The second two ships will be exclusively tasked with area air defence. The platform design is based on the Karel Doorman hull for speed and seakeeping. Signatures have been kept to a practical minimum. Blast and shock hardening measures have been carried through by use of Blast and Fragment Retaining bulkheads, protected ducting of piping and cabling and shock floors. NBC protection is set to high standards.
