I'd have to agree with the too-streamlined suggestions, but since it's such a small ship (about 90m to the big "E" at 289m), you can probably get away with it, for the most part.

I saw the Sabre similarities before I read your post's text (^_^), but it also reminds me of the ISC Gunline ships from that "Starfleet 2300" white metal miniatures line. They were alien starships, but flew backward in relation to this design - they had a big gun where your main hull is... The only people I know are familiar with them are those who have played "Starfleet Command" in its hexagon-board game venue.

Incidentally, I like the different signage you've employed with the earlier ships...!

Get ready for a dual-ship series dealing with multiple timelines.... *grins*

I've never seen the white-metal miniatures you mention. I only know the FASA variations on the original and refit Constituion hulls.
