Interesting - the nacelles are shorter. Seems to be reversing a trend. Let's see more when you get it.
Try Transwarp capable. And yes, it is supposed to be three times the length of a Sovereign. Around 2,000 meters. I started out with 3,000 meters but scaled down somewhat. I wanted the ship to have the "aircraft carrier feel". You know when you see those pictures of a Nimitz class aircraft carrier at the center of a carrier battle group, dwarfing all of its escort ships. I wanted this ship to have that same feel. The Terra class starship has all the usual "heavy cruiser/long range explorer/flagship" capabilities. But from a military standpoint, the ship is supposed to function like the proposed Japanese super battleship/super carrier Shimano (IIRC). A conversion of the third battleship of the Yamato class. The idea behind the Shimano was not only would it be a powerful ship in its own right, but be big enough to carry fuel to sustain the other ships along with it. My idea for the Terra was that not only would it be a unit as powerful as it should be for its size, but that it would be able to carry extra antimatter, deuterium, industrial scale replicators, torpedoes, phaser emitters....and most importantly, replacement starship personnel so that it could sustain a small fleet by itself if necessary. By the way, I haven't found the right look for the Transwarp Driver Wedge, so the engines are really just place holders.
Shinano- wiki Shimano are bike parts. Biggest problem I'm seeing is that you'd have a crew compliment in the 1000's... kind of risky in any of those duties.
Sure, a crew complement in the thousands. I envisioned a "typical" crew of 3,551 with a "war time" crew of 7,000 or so. Even then, given the vast size of the ship, even with a 7,000 man crew to someone walking on one of the decks, the ship would seem largely deserted as they would likely rarely encounter other crewman.
What is your logic for retaining the distinct saucer/engineering sections? That saucer has an immense volume. Assuming it is a similar shape to a Sovereign primary hull gives it a volume roughly 170 times larger than that of a Sovereign class saucer section. If it is more of a Galaxy class shape that number will be even higher. You mention industrial scale replicators, where on the ship are these located? I assume they would be internal facilities, if so you need some big bay doors on there to get stuff out. All the windows around the saucer/neck are incredibly massive as Paladin pointed out. Given the massive size of the ship and the fact that windows are placed everywhere it implies that the habitable areas are a thin skin around the exterior of the saucer, about the most dangerous place you could keep everyone on a ship intended for combat operations. On a similar note, those nacelle pylons are an amazingly tempting target for any attacker. That pylon is at least a couple of hundred meters long, why would the designers put the nacelles that far away when it not only makes them more vunerable but also requires a larger shield bubble? It's an interesting idea you have, and the drawing is interesting, however it seems like you are drawing a big ship having picked a random massive size and are then trying to fit the functions in. I would suggest first off taking your list of requirements and one by one working out what they would need.
Of course people will live by the windows. Is it dangerous in battle? Yes. That's why you have battle stations.
With a ship this large and important why have all those weak points though? This ship is large enough that the hull could be made of 10 meter thick titanium and it wouldn't add much to the overall weight.
I'm no good at surface detail so I simply copied the surface details on the saucer from a smaller ship (that was about twice the length of a Sovereign). The ship doesn't have engine PYLONS. It has only one. A thick and massive one projecting upward from the secondary hull to which the engines are attached. Again, the engines are merely interim place holders as well. In my Trektech, for true transwarp capability, the more massive the ship the faster it can travel at transwarp speeds. So it makes sense to build some truly giant starships.
Didn't I read somewhere that the US was also thinking of building one of these massive supercarriers at one point? (The boat, not spaceship.) The problem is they become huge targets, and it is foolhardy to have so many other ships depend on the one ship. I read in one of those military magazines my dad used to buy they were also proposing engineering a movable island which a bunch of ships would carry parts of. They would put it together in the middle of the ocean and be able to launch airstrikes off the island. That way, they don't have to ask for permission from countries to land and refuel at their airports.
I don't think the U.S. Navy has considered anything radically larger than the basic Nimitz class because there are no construction facilities in the U.S. capable of building anything larger at this point. But yeah the artificial island concept built much the way giant oil rigs are constructed has been considered. Basically a giant barge with a mile long runway on top and facilies to base as many as 10,000 Marines at one time. I always got the idea they wanted to put one in the Indian Ocean closer to Middle Eastern targets than Diego Garcia is.
Is it my imagination or does the Vengeance in "Into Darkness" bear some resemblance to my ship in profile views? http://scifanatic.wpengine.netdna-cdn.com/wp-content/uploads/2013/04/stid-t5-25.jpg
I totally see it! It has a saucer, an engineering hull, and two nacelles. Shit, man, you should sue them.
But I thought both Dayton's ship and the big one in STiD were the Enterprise? Like you say, they've both got a saucer, an engineering hull and two nacelles.
