So, I was just looking at some measurements:

[thesovereignman]

And for future JJVerse ships to be in the same general ratio as old ships, they would have to be enormous

The old ships:
Constitution 289 meters; 430 crew
Excelsior 511.25 meters; 750 crew
Ambassador 478.5 meters; 700 crew
Galaxy 642.51 meters; 1014 crew
Sovereign 685 meters; 855 crew

New Ships
Constitution 725.35 meters; 1100 crew
Excelsior 1278.12 meters; 1912 crew
Ambassador 1196 meters; 1785 crew
Galaxy 1606.275 meters; 2585 crew
Sovereign 1712.5 meters; 2180 crew

All of the original measurements come from memory alpha. I used a formula of 2.5(OL)=NL and 2.55(OC)=(NC)
OL=Old Length
NL=New Length
OC=Old Crew
NC=New Crew.

As you can see, the New Constitution class is larger than a Galaxy class!

I have no opinion about it either way, these measurements are to help people who want to design JJVerse ships.

To throw you for a loop, Andy Probert (who designed the Galaxy Class) has always said a Galaxy should have 3,000 people aboard at any one time. When he mentioned this to Gene Roddenberry, Gene's response was "I don't have the budget for 3,000 people!"

And for future JJVerse ships to be in the same general ratio as old ships, they would have to be enormous

Not only that, but all the old ships seen in STXI would have to be ginormous as well. After all, they are all the same size as the hero ship, or even larger. Some are much larger, like the one saucer in the wreckage that Sulu steers around.

They all probably have crews in the thousands, then. And some in the tens of thousands.

Or then the hero ship isn't as big as they claim.

It certainly doesn't look as big as a galaxy class, if the shuttles are any clue.

which also begs the question, how in the hell are they filling their ships? epecially since it seems that humans are a majority in the crews.

Wave after wave of my own men...

 

[Johnnymuffintop]

Since the OL to NL ratio is what it is, my DY 100 design is about the length of the prime Constitution.

You saw all the vertical buildings in the movie.
Hell, they could be packed in there to the point where there are at least 15 billion people living on Earth.

 

[thesovereignman]

Since the OL to NL ratio is what it is, my DY 100 design is about the length of the prime Constitution.

Slightly shorter, the measurements from Memory Beta is 100 meters, making the new measurement 250 meters.

It's possible that the DY-100 would remain unchanged, because it predates the alternate timeline.

 

[Johnnymuffintop]

Well, the Kelvin predates the altered timeline, and yet...

I think if pre-TOS ships make an appearance in later trek, their design and size will be determined at the discretion of the director (hopefully still JJ), asside from very exact sized ships/spacecraft, I.E. the voyager probe or any other thing we've already sent up.

 

[Captain Robert April]

The JJverse is clearly a product of the Temporal Cold War left unchecked, so all bets are off on everything. For all we know, the Botany Bay in JJland is an exact copy of the SDF-1, complete with aircraft carrier arms.

 

[Maxillius]

The JJ Enterprise looks smaller than a Galaxy because it is. Even though the JJprise is nearly 80 meters longer, that saucer is round rather than a horizontally positioned oval. so the Galaxy is very likely still wider than the JJprise.

Yeah, the thing about your measurements is...this is a new universe. Obviously we aren't going to have Excelsior, Ambassador, Galaxy, and Sovereign classes now, so there's little reason to speculate about how much bigger they're going to be. I'm sure that the reason why the new Enterprise is still even called a "Constitution Class" ship is because it was probably on the drawing board in it's original TOS configuration with that name until Nero's incursion changed things.

 

[Crazy Eddie]

As you can see, the New Constitution class is larger than a Galaxy class!

No, it's just longer than a Galaxy class. The Galaxy's internal volume is still signifigantly higher, not least of which because much of that 725 meters is actually the length of the warp nacelles; the entire ship is only 460 meters from the front of the saucer to the end of the shuttlebay. Compare this to the Galaxy class, which is 640 meters almost to the end of the secondary hull.

To illustrate this even further, one should consider that though the battle section of the Galaxy class has approximately the same length and width as a Constitution class starship, it is about three times its overall volume.

All of which means simply multiplying the lengths of these ships to come up with new sizes is probably a waste of time. I half believe the Galaxy class ships of the JJ Verse would be the same size as in the Prime Universe; they serve the same function, after all, and despite a few technical design changes would probably be constructed around the same specifications.

As I've pointed out about a zillion times, it isn't. The saucer of that vessel (probably the mayflower) is almost exactly the same size as the Enterprise's saucer.

 

[CuttingEdge100]

STR,

If I recall correctly, Andrew Probert listed the crew-complement for the Galaxy-Class as 3,800

 

[Captain Robert April]

^ And had it promptly cut by two thirds by Roddenberry.

 

[STR]

STR,

If I recall correctly, Andrew Probert listed the crew-complement for the Galaxy-Class as 3,800

Even better. The Galaxy has 25 times the volume of the 430 man Constitution. You need something to fill all that space.

 

[Maxillius]

3800 makes more sense if you make the crew quarters more like barracks and low-rank officers double bunk. Also, note that a Galaxy is set up to carry families as well as the crew so having 1000 officers and crew allows each member of Starfleet to bring on average 2.8 family members to make the 3800 personnel count.

 

[STR]

Umm....not quite. A galaxy can pack 10,000 people and maintain the same standard of living as the Constitution. Again...25 times the volume. That's a lot of space to fill. It's so much, that there really isn't a man-made structure in the world you could compare it to. The World Trade Center came close, it was only half the size of the Galaxy Class.
