My conception of the Daedalus class, as derived from a side elevation of the NX-01. (Larger version here.)
I intended to show early progression between the NX type and the USS Kelvin. This Daedalus design has a relatively small secondary hull, and large engines. The window and airlock detailing indicates that the ship's size is roughly 296 m, which makes its engines vastly larger than those of the NX-01 (diagram below). Presumably, the relative size of the engines relates to some new development in warp technology - possibly stemming from the technology shared by the new Vulcan government. I would imagine this ship is capable of Warp 7.2.

I had a lot of fun producing this image, even after several frustrating hours spent trying to work with a line-drawing version.
