Class particulars
The design of the Karel Doorman class reflects the increasing priority that the Royal Netherlands Navy gives to survivability. Designed to reduce the Radar, Under Water Noise, Infra-Red and magnetic signatures the ships have an extensive NBCD arrangement.
The hull design is based on extensive research into seakeeping and propulsion, giving high sustained speed in seaway and a wide weather window for helicopter operation. Equipped with a rudder roll stabilising system.
Highly automated in machinery control and C³I systems the class has a characteristically low manning level.
International interest in the M-frigates as well as changes in the Royal netherlands Navy prompted the sale of two frigates each to Chile, Belgium and Portugal. New names are:

F827 Leopold 1 Belgium
F829 Louise Marie Belgium
F830 Almirante Riveros Chile
F832 Almirante Blanco Encalada Chile
F833 Unknown Portugal
F834 Unknown Portugal
