Harry had said these two ships exist but there were no details. They seem to be in the same category as some Iberian crusiers of the same period so I worked on about 15,000tons and guns between 8" and 10". Not quite a battlecruiser - more a super armoured cruiser.
I'm just sketching these out, they are like Harry's previous ships - French influence and American armament.
