The 3 Guardian class cruisers, "Guardian", "Protector", & " Defender",
are part of the Emergency Building Programme of the Danish Navy in 1914,
to bolster the ability of the Navy to undertake the maritime security of the Danish Protectorates,
and are designed to patrol the Danish Protectorates in the Far East and Africa.
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 Protectorates.
They are built for long range and high speed, with a degree of comfort for any diplomats aboard.
