"The main class variant is the Minerva/A which has only one class-1 beam battery for offensive fire but carries an Area Defense Fire Control system and an additional PDS installation in place of the class-2 battery and the other class-1; this version is commonly used as an anti-fighter close escort for merchant convoys and support ships."

"The Huron is a rebuild of the earlier Hoshino class hulls that were built between 2157 and 2165; the lack of suitable replacement CL designs in the mid-2170's caused the Admiralty to look at ways of extending the service life of the obsolete Hoshinos."

Battledreadnoughts
"The Excalibur was introduced to service quite recently as a replacement for the Avalon class BDNs built in the mid-2160s.  The Avalon class was never a very successful design, and in 2176, a decision was taken to rebuild all remaining Avalon hulls into the newer Excalibur configuration, which entailed significant full modifications and complete internal upgrading.  Rather than recall all the ships en masse and leave the fleet seriously understrength, the refit programe has been spread out over several years as the Avalons are rotated back to major fleet bases for overhaul; as of 2183 there are still a small number of unconverted ships in service in outlying regions"
