The Rotterdam class is a Landing Platform Dock (LPD) amphibious warfare ship of the Royal Netherlands Navy. The class was the result of a joint project between the Netherlands and Spain, which resulted in the Enforcer design. The ships are equipped with a large helicopter deck for helicopter operations and a dock for large landing craft. The ships have a complete Class II hospital, including an operating theater and intensive care facilities. A surgical team can be stationed on board. The ship also has a desalination system enabling it to convert seawater into drinking water.
