^^ The mechanicals and systems of the era are also meant to be bulkier so the ship wouldn't be as spacious in accommodations as TOS era ships. And note my little posted image says "approximate size comparison." The ship could still end up being a bit smaller, but probably not by much.
One of MJ's sketches for the Daedalus
type design had the name Independence
on the front, so I've decided to call my version the Independence
-class even though I'm deviating from his sketches.
