You're right, Praetor
. Sorry. I did some more research and came back and deleted my post. I knew that a year ago but had forgotten.
sold me on the idea of updating the deck count, which I did. And Jackill's version, with more decks than the Galaxy class, was a bit surprising to me the first time I saw it.
For now, I've got it like this, which seems reasonable, although I noticed my saucer rims are slightly off, even though I reversed and pasted the aft one after drawing the forward one (but probably later modified it when trying different ways of showing the Bussard collector while clarifying how the impulse engines fit in there).
