Karel Doorman/Adelaer-class Frigate

The Karel Doorman-class is a class of eight multi-purpose frigates of the Royal Netherlands Navy. The class is also known as the "Multi-purpose" or M class. The ships are named after famous Dutch naval officers, the lead ship being named after Karel Doorman. In 2008, the Karel Doorman (F827) was renamed the Adelaer after the commissioning of the multirole vessel Karel Doorman (L802).

A total of fourteen ships were built; eight for the Royal Netherlands Navy, two for the Belgian Navy, two for the Chilean Navy and two for the Portuguese Navy.
