Thoughts now turn towards a new cruiser.
I quite like the Breda's and my first thoughts were to modernise the design and fit the planned armament of Kirk's Province Class
Province Class. However more elements of the Province have crept in and the design is now roughly the same but 1kt slower and I feel this is generally superior to Kirk's design which lacked misc weight for all the amenities and the turrets. I feel this is about the best likely to be achieved on a good balance, but I may tinker more before laying these down.
