The first 2 ships of the Island class, "Bornholm" and "Falster" were selected

to trial the "Hunin" system in advance of future deployment on other vessels,

and due to it's success, will be fitted to all the class.

Valkyrie II class fleet escort cruisers are specifically designed to use the 120mm turrets designed to be retrofitted to the "Hel" class CAs. They are to supplement the anti-aircraft capabilities of the fleet. Turrets simmed as triples to simulate increased weight of HA/LA mounts, twins actually mounted.
