The recent new thread showing a possible movie image of the "new" STAR TREK's Starship Enterprise finally motivated me to post a couple of new drawings.
This isn't much, but here goes:
This is my idea of what the new/reboot Enterprise "could" look like.
This simple pencil sketch shows my alternative to the new movie image. The secondary hull on my version of the "Enterprise" would have a shape similar to the classic TOS design, but would be much longer at the aft (hangar deck) end. This hull would remain cylindrical in shape. The interconnecting neck would be much thicker. Out of the sides would jut podlike tubes which would serve as the bases for the nacelle pylons. These tubes would house photon torpedo launchers.
The next is an unrelated concept; something I've been kicking around for a long time...
This is the Starship U.S.S. Herman: my answer to Franz Joseph's Class I destroyer/scout single-hulled starship. Named after the Hermes, this class of starship would have its origins in the "STAR TREK: ENTERPRISE" era (a descendant of the NX-Alpha Warp 5 prototype) as an Earth and/or Coalition class of warships, smaller than the NX-class, serving in the Earth-Romulan Conflict. The design was among the first to become part of the new Federation fleet a few years later. Refits over the years kept the design current through the TOS era.
This particular drawing set is of a TOS-era version of the Herman design.
The side-view is drawn with the nacelles deleted for clarity.
The basis for this concept was my ages-old (lost in the mists of time) thread that asked "How would you re-imagine the NX-01 Enterprise?". This was one of many ideas I had in the back of my head. The concept was to continue the idea of the NX-01 based on a single hull, with design lineage ties to the TOS Enterprise, but far removed from the onscreen ENT that so many fans dislike.
In my Herman, I came up with a way to "have your cake and eat it too". The ship is faithful to the TOS design convention of separating the engineering and hangar deck from the bridge/crew quarters section, yet all are part of one "hull". The solution is to base the ship on a single tube hull shape, and segment the various sections. The bridge and crew quarters are in a forward nose section. Warp Drive Engineering is in a larger mid-section, and the hangar and impulse engines are in the aft segment.
Using a segmented single hull makes for a smaller, simpler-to-build ship. The forward "nose" section is actually a topside half of the tube with the underside half eliminated, forming a saucerette.
The mid-section is more of a cylinder, like the forward half of the TOS E's secondary hull. This section houses the warp drive engine room, fuel storage, the navigational deflector, cargo holds, etc.
The aft segment is more like the aft end of the TOS E's secondary hull (hangar deck) except the ship's impulse engines jut out from the sides of that section, forward of the hangar.
Of course, as with the NX-Alpha and its great-granddaddy the Phoenix, the nacelles are rotated to oppose each other. The TOS-era version of the Herman uses nacelles that are supposed to be closely related to the nacelles used of the TOS E. (Roughly same overall dimensions.)
