I don't know where I am going with this, but I was looking at a piece of office furniture (a monitor stand) and started sketching this very utilitarian ship. It's for short close contact missions. You can see 3 shuttle doors on the side. There's 3 on the other as well making it a through deck. Most of the work space is in the secondary hull with the small upper command hull in an unusual square configuration being significantly lesser in volume in proportion to the rest of the ship. Size and crew is yet to be determined, but I'm leaning towards a secondary hull about the same size as the excelsior's. It's certainly meant to be a work vehicle. The luxuries of a Starship are at a minimum because they're just not needed. It's meant to always be in close proximity to a starbase.
