Just a couple of random questions I've been thinking of. When do you think the second Excelsior-class ship was launched and do you think it was the Enterprise-B? Are there any contemporary ships to the Ambassador-class starships that use similar designs, like how there's the Constitution/Miranda or Galaxy/Nebula? Was the Ambassador-class the replacement for the Excelsior-class or was there another major capital ship in between them? Cheers.
