I agree with your thinking. The ship does need a hangar for a shuttle because transporters were not in use then. The strut holding the ring as a hydrogen collector makes a great deal of sense, because I always wonder how they would collect hydrogen for the propulsion of the ring. You are on the right track and in line with my thinking of the Valiant. My Valiant is different than yours, but has similar necessities as yours. It is simialar in design to the Valiant designed and built by Greg Jein and to that of the Conestoga. Great work so far. Good thought processes.
