seeing not one but two on screen again in LD reminded me what a cool ship this is
for reasons cited above I had this ship on my mind again, and looked back at the last ships of the line calender it was featured in. It has an ugly-but functionaly pretty look akin to something like the B-17 bomber, to me. Subjective of course.
But to stay on topic, as this is Trek Tech: I was thinking that going off the model in Deep Space 9, this is one of the most functional looking ships in Star Trek. It's an early ship, predating the NX according to the calendar (not canon, I know, but very little about these ships is) .
The Nacelles look very much like smaller segments bolted together. For that matter so does the cylinder neck and the secondary hull. I would like to see a version of the NX Refit with a Daedalus secondary hull and not the more Connie looking hull given to it.
The nacelles of the Pre-NX intrepid look similar to the Daedalus models, again suggesting the ships were made at multiple small facilities, and either brought to orbit for assembly or else assembled at multiple smaller orbital yards, reflecting the early nature of starship building and/or the needs of construction during the Romulan War.
The most noticeable feature of the Daedalous though is the spherical hull. Starfleet has used them since, but sparingly, Why then would they have been used initially? Spherical hulls are good pressure vessles. The Vostok and Voskhod spacecraft used them for reentry vehicles, for instance. But Enterprise the series showed no spherical hulls on other ships. clearly they always tended to favor saucers and deltas.
Myy suggestion is that, like the nacelles, they were easy to make. Daedalus was always an economy model, the Liberty Ship of its era, then
imagine the hulls formed explosively, then fitted out in orbit
