That is, as far as I can tell, not how that works?

The inverse slope isn't described as providing more module space than the command config, and if you look at the Excalibur diagram that checks out. The sloped volume just isn't the correct shape to put any deck-height systems in.
Our weapons have always taken up some internal space, even if they usually don't explicitly take up a module slot. You can see it in the diagrams.
That is quite a lot of volume. It is also very unfortunately shaped volume, since our stuff is rectangles which do not efficiently pack into triangles. That means that it will be quite heavy due to the raw volume, while being much less useful than our main decks.
Think of it three dimensionally: Curve that area around the saucer, and it's actually quite a bit of volume.
 
The command saucer also extends behind. It basically shoves all the crew quarter into a big long rectangle from the center to the back of the saucer, rather than sloping as far as I can tell.

Now the command saucer does seem to only put the crew stuff in there, so it doesn't get that extra not quite deck space, but I don't think it's worth paying for 30kt of volume that's not deck space.
By virtue of not being a ridge filled with just crew quarters (which will probably only be one deck, if it's more then that'd mess up the phaser firing lines) it will provide usable volume, of the overall volume it adds only a comparatively small portion will be not usable for module purposes.

If you think that the extra 30,000 tonnes won't actually provide any deck space then I've got a bridge to sell you. Furthermore the extra mass, even if it doesn't provide any deck space (which is basically impossible) will improve not only the tactical utility of the starship but also provide us with a more massive secondary hull, further increasing general utility.

Yes, and as depicted on the diagrams, our weapons take up full deck height, which the slope does not provide.

And that's the problem. It's a ton of volume that's suboptimally shaped, so we're paying for a bunch of mass that contributes a proportionally much less useful amount of volume.

If we just take all the actual deck space that you get out of it and consolidate it into an efficient brick, then that's the command configuration. I'm not sure that actually works out to 30kt math wise, but I'm not going to think about that too hard.

Our phaser firing lines are basically irrelevant since we can't fire more than one or two at a time, and the command saucer should have an equal amount of crew as the incline, which is described as using most of its space for crew.

The update suggests quite strongly that we're not going to get any meaningful deck space out of the inclined saucer:
This stacks more space above the main decks but will still largely be taken up by crew quarters, but does provide some wiggle room for extra transporters and the like.
I'm not sure the mass savings from cutting out all the inefficiencies from the incline and consolidating the useful deck space into a ridge down the center of the saucer would actually be a whole 30kt, but it doesn't sound like the inclined saucer will have major module benefits either way. I'd bet on saucer modules being half a tier better or something like that.
 
I mean, we chose the design brief that only had a vague tactical goal and literally no specific peacetime goal beyond "don't suck" so it's to be expected that the design is a bit confused. We're only like three votes in though, so I'm not terribly worried.
Agreed, I was also saying that to an extent after all. I was replying to a poster worried about the design focus shift, with a note that it was a bit to early to give hope up on the design. We will have to see how things progress.
 
At worst we make a somewhat bigger tougher Excalibur to act as fleet anchor while having more civilian utility than the Excalibur.

Starfleet needs that and it would at least be made in decent numbers.
You kinda highlighted my problem with this: It's a ____ ____ Excalibur.

We don't need a ____ ____ Excalibur. We have THE Excalibur, one of the best ships we've designed since the Skate. Just use that! Or keep using the Refit Kei!

There's no point to this if we skimp too much on tonnage because the Shielding and Phasers scale with size to a degree, and we also need keep in mind that we need to have space for a respectable number of modules while still keeping a high ass kicking capability.

Remember, we've lost modules to weapons in the past or visa versa, and this ship is going to need both.

The Excalibur is a great ship... But it's not a ship to build a line of battle around. It relies on speed and mobility to defend itself and put the large number of photon torpedoes on target.

We do actually need an Excalibur but geared to be a shield rather than a sword.

If anything the Excalibur suffered for a lack of a peer ship to work with in the last war. It DIDN'T have a solid line ship to maneuver around so it couldn't get the most out of it's maneuver.

Even if all we do is make the Aegis (named for famous shields) class to work with the Excalibur class it will be useful.

The wall of battle was both weak and slow, unable to be where it needed to be and suffered undue casualties when it actually got to battle. This meant that the Excalibur was frequently working as a raider.

We also need a vessel Starfleet won't just abandon production of once the 'worst passes', like they're doing with the Excalibur. For that, we need room for modules while allowing us to keep a respectable armament. Now, we might get a good Secondary Hull that gives us the Mass we need, it happened with the Kei...but I can't help but be worried.

If phaser firing lines are basically irrelevant then why did so many people justify voting for the command style deck with the logic that as a Kea successor we needed the best we could get!?

You don't really seem to get what we're saying, yes the crew volume will probably be equal but with the inverse slope well actually be able to do more than just stuff crew quarters there.

We're pretty explicitly told the difference in mass is a whole 30,000 tonnes. And as that drawing you like trotting out so much shows after a comparatively small section of slope where modules can't be fitted we get two whole damn decks, and given the size differences (the saucer being 40m wider) we might even get three.

Even if we don't, as the full version of the drawing shows there's a ton of two deck modules that could be fitted in such a space.


Given the size differences that could be as many as four 2 deck modules in there.

Wouldn't one normally in real world designs just cut the roof out to get more height clearance for the floor below for the particular narrow parts? Then one could install taller facilities in the deck below after all. I'll grant you that isn't in the depicted picture, but still if we assumed a sane designer you'd think they'd not just leave empty space if they could find a use for it, be it machinery or modification of the deck layout. As such I'm not entirely sure we should take the pic as the final gospel truth of everything and that if nothing is displayed in it for a section that means there is nothing, that might be expecting the QM to do put more detail in to things then they may really want to.

So I guess in the end the question is a bit like... is the design just all direct game logic, or is there a certain level of fluff to it? I guess?

It actually was also built with heavy shields though. So if the tonnage range doesn't differ much then in pure toughness at least there wouldn't be a big difference. Thus why some people can wonder if there is a point to the other class if they're to close, because you could just create a spin-off class like they did with the Attenbourough instead. In which case you'd gain some more efficiency in having more of the same designs where parts are easy to supply of.

Still this is all predicated on the idea the tonnages would actually end up close. Like if this Kea class only ended up at 200.000 ton or 210.000 tons.

Nothing we build here won't have a short run. Starfleet is about to update shields and nacelles again and anything we design is more or less a stopgap until those two new systems come online.

But I was going to suggest Aegis before I saw your edit!

Yes, Aegis & Excalibur is a pleasing pairing and gives a theme to design towards.

The Kea had the volume to allow for a refit, and even then it had to have things ripped out.

This is not true.
The freaking Kea was in service until the 2290s. Unless we fuck this up by the numbers, anything we build here will be in service for decades yet.

And Starfleet has been explicit about the need for hulls.
Ive done the numbers.
We need well over 60 ships in the next ten to fifteen years just to come close to replacing combat losses.

We know there was a Fleetwide refit of nacelles in the 2270s, so the ships might be around even longer.

EDIT
The Attenborough was in service for even longer.
Unless you build an utter mistake like the Radiant-class, your ship will be in service for at least three decades, with the good ones being around for six decades or more with upgrades.

Incorrect, as the fact that SanFran is designing what we know is explicitly the TOS version of the Miranda shows if a ship has enough utility (which the inverse slopes volume and future mass allowances will provide) or is cheap enough (Miranda is a minimalist design) or some mix of both it will continue to be produced for decades.

A command deck style saucer precludes extra utility, both in the volume it removes and in the mass that it 'saves' (as it will directly impact the size of the secondary/engineering hull.

To quote myself from last night:
"People who are voting for the command configuration on the basis of "we were told not to bulk it up" are generally ignoring that we can and will add extra functionality with that mass, both directly in the tactical sense and indirectly in terms of the module fit we can give it.

As it stands the command configuration ship is probably going to be of limited utility outside of combat, which will directly impact on the longevity of the ship and how many Starfleet gets built."

I think it's also fine mass-wise if we take the smallest option here? The largest one is effectively a non-starter because of the torpedoes, and the middle one doesn't sound like we're getting meaningfully more modules compared to the small one. And the small one has some nebulous phaser benefits, and we do want plenty of phasers on a fleet anchor.

And we don't really have any reason not to take the largest secondary hull, so I imagine we'll probably take that. And then we add the mass of the nacelles, and we're basically at Kea tonnage.

If phaser firing lines are basically irrelevant then why did so many people justify voting for the command style deck with the logic that as a Kea successor we needed the best we could get!?
The update just described a flat surface as ideal for phaser placement. I assume the firing lines thing was what some people assuming that meant?
Given the size differences that could be as many as four 2 deck modules in there.
We are very explicitly told that we are not getting anything significant with the slope:
This stacks more space above the main decks but will still largely be taken up by crew quarters, but does provide some wiggle room for extra transporters and the like.
There's no way that "wiggle room for extra transporters" becomes four whole modules.

So I guess in the end the question is a bit like... is the design just all direct game logic, or is there a certain level of fluff to it? I guess?
I believe the last time Sayle commented on it it was all WiP, but I'm pretty sure it's a mix of what can be physically drawn in the diagram and how big different sections are?

We're already quite a lot larger than the Excalibur, since that had a 140kt primary saucer with the nacelles included. The Kea has a 140kt saucer without nacelles, so I suspect that we're going to be equal to or larger than the Kea regardless of which option we take. I don't think most people have figured that out yet though.
 
Looks like we're inevitably slouching towards the Excali-basura.

...psst, I've got a couple thousand overly-ambitious Marines I need to dispose of, I could send them to your universe to burn the Utopia Planitia memory banks...

Thinking about it a bit, I realized Starfleet can probably recover a fair few resources from the wreckage around Andoria. Now obviously a fair bit will just be lost or non-recoverable, but there should still have been a fair chunk of resources to be had there. So in that sense Starfleet might have a bit more in the bank in strategic reserves then normally, especially as normal resource gathering should continue apace as well.

Still I imagine that will at most help in rebuilding a bit quicker. Perhaps the production runs can be a bit bigger then otherwise.
 
I don't think it really matters at this point, but for everyone panicking about the mass, the Excalibur's primary hull was 140kt with nacelles:

To simplify your analysis the mass of two standard nacelles have been added automatically, leaving only the mass of the secondary hull undefined.

140kt without nacelles is what the Kea has. We're effectively guaranteed to at least match the Kea in mass here.
 
Looks like we're inevitably slouching towards the Excali-basura.

Ok, but there is something wonky going on with the tonnage. The Excalibur having a 140 meter two deck half saucer that weighs 140 Ktons while the Federation has a 180 meter three deck full saucer that also weighs 140 kton just doesn't make sense.

But the Excalibur seems to have the mass of nacelles and other stuff assumed in that calculation so... The only way this makes sense to me is if there is a lot of mass that is going to get added that was added at the front end of the Excalibur.

And we have confirmed that nacelle weight isn't added yet.

So assuming the nacelles weigh 10-20 Kton each the Excalibur main saucer really masses 100-120 kton and we are somewhere around 15-40% bigger.

Note to @Sayle

Maybe a better way of going about things in the future would be to present an "expected" mass total assuming roughly average choices during the vote and for vote options to add or subtract from that value as they are lighter or heavier than average. This would let voters aim for an end result rather than steer fairly blindly.

That way the shield vote would have given a target mass alongside it, then decisions would flow from there. No details, just Heavy Shields (roughly 200ktn), Standard shields (roughly 250kton). The player votes would then diverge from that baseline.

Yeah, it will help with strategic material availability, hopefully.
Still need to build the hulls and the hardware that goes into them.
Even at 6 ships a year, which was wartime production speed for the Excaliburs, we are gonna need a decade to roll out 60 ships.
