Dutch navy vessel HNLMS Holland, in Oslo

HNLMS Holland is the first ship of the Holland-class offshore patrol vessels of the Royal Netherlands Navy. The ship was originally designed to fulfill patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers. However, it also has very advanced electronic and radar surveillance capabilities which are used for military stabilization and security roles, short of outright war. Without sonar or long range weapons, it utilizes the surveillance capabilities of the Thales integrated mast, which integrates communication systems and two 4-faced phased arrays for air and surface search.
