The Kingdom-class are a class of highly sophisticated air-defence destroyers in service with the Royal Union Navy and Medosian Navy. The programme started off as the Common New Generation Destroyer (CNGD), a multi-national collaboration to produce a new generation of air-defence destroyers. In Medos the class is known as the Bresea-class, which translates to boroughs in Dalean English. The project originally included Chelonia,Arendale and Medos,however due to differing requirements from the Chelonian Navy for a larger ship, Chelonia proceeded to develop the Fregnet destroyer instead.
