Hi all! Thought I'd throw this one in for general discussion. It was suggested that the Enterprise A could not have been built in so quick a time that the ship was actually the Yorktown renamed. This theory however was put forth by Gene Roddenberry and I actually don't consider him the utmost authority on these matters Tbh lol. He also suggested that only a few Galaxy classes would ever be built and well we know that turned out to be untrue. Also it is very likely that Starfleet had many Constitution refits on the assembly line by the time of Star Trek IV-VI (such as the Endeavor, Ahwahnee and Emden so I'm think it was most likely a new ship and not refurbished as Roddenberry suggested. What say you all?
