Guardian class cruisers, "Guardian", "Protector", & " Defender", are designed to patrol the Danish Protectorates in the Far East and Africa,
and as a result these vessels often take on the role of floating embassies for the Danish Crown.
Their Primary duties are the protection of the merchant marine, and the overseas territories.
They are built for long range patrols with decent speed.
