You only need four historic ships, and the wiki says it's random, but I went to the HP boss six times in a row with the historic fleet, so I think it might be from in the past when people thought Hatsushimo and Wakaba were historic ships. It turned out they aren't and so any "historic" fleet with them might have been random.
