What is the ''OFFICIAL'' length of the 1701?

I was under the impression that some well-informed people tend to believe that there are (a) issues with the overall size of the bridge set fitting in the dome even in the 'rotated' position and (b) issues with the turbolift alcove and/or turbolift position fitting.

As far as I can tell, the set diameter and bridge dome are 'close enough for government work'. The exact measurements may be off but we have to remember this is a Hollywood production, and not a group of engineers making a real starship. They're not going to get the details exact, ever, and it's really kinda stupid of us to expect them to. The importance was making the show, after all, not satisfying nitpickers 40 years from now.

Personally I've taken the view that, as Hollywood actually did, the lift and station immediate starboard were swapped for dramatic reasons. Solves all the issues neatly. If that's too much, the other obvious solution is to correct the location of the lift housing on the model itself, sliding it to port a little bit. (I've been tempted to do this on my Jaynz models, just to see if anyone would notice.)


There are two possible solutions to the problem: reduce the number of decks (which is a popular strategy) or resign oneself to the fact that all decks may not be the same height.

Nah, I think that the deck number is largely correct but that, once again, the needs of Hollywood hurt the realistic portrayal of the ship a bit. Amusingly, the deck heights shown in the ship diagrams match the hard line on the walls just above the doors. We can pretend that anything above that 'on the sets' are actually not really there. ;)
 
Of course one can shrug it all off as just a TV show and it doesn't matter. But if you are interested in rendering an integrated ship where everything fits together as if it were real then you have to find ways to make things work and toss away some preconceptions and long held assumptions.

If the 947ft. figure ends up being totally unworkable for a real ship where everything fits as it should then I'd toss it away in a heartbeat.

I just find the 947' metric to be one of the least objectionable notes about the ship. Honestly, we see how big that thing is next to an aircraft carrier with a fraction of the crew and much less space needed for the hangar deck. The ship is plenty big, functionally, at the indicated size. Tweaking the sets to fit the ship seems like a logical approach from here on out.
 
One needs to ascertain exactly how big the bridge set is. Do you accept the likely 9/10ths scale it may have been built at as the "real" size or do you try determine how big a real bridge would be? Then how is it supposed to fit under the dome atop the saucer hull. And finally remember you're trying to fashion a "real" ship and not just one of plywood sets and plywood hulls. That means you've got to include likely mechanicals for such a ship and a believable hull structure.

Candidly I don't think it really matters anymore one way or the other.

Related to the bridge, though, is this question: does the main turbo lift shaft have to be on the ship's centerline? If you have a forward facing bridge then the shaft doesn't need to be on the centerline until you get to the dorsal. Otherwise for symmetry's sake I suppose then a centered shaft dictates an offset bridge at the top.

True, but you can grab the layouts of most modern aircraft carriers and submarines to get an idea of the machinery. As far as the bridge goes, it's mostly computer controls and information screens - not exactly high-machinery area. There's plenty of space for all that under the boxes.
 
^^ I rather liked how FJ had a service space between the bridge and the outer hull. It doesn't have to be exactly like that, but I don't see the bulkhead just behind the stations as being the outer hull. I see it more credible if there's "stuff" between the inner bulkhead behind the consoles and the outer hull.

Overrruled. Contempt! 90 days watching "And the Children Shall Lead"!

Ugh! Do I hafta?

My memory fails me, but I think someone here had the viewscreen up front, the turboshaft directly aft, and explained it all by having a ring for extra turbolift cars surrounding the bridge to either side--so the car would come up to the bridge, then swing around it. The top of that bump perhaps linking to a larger station just above or maybe another ship...

To me, Enterprise was as big as needed for everything to fit. Seeing Trek ships so small on the merzo.net site doesn't sit well with me, thus no problem with the TOS ship beiing JJsized for the shuttlebay in TAS to work. Over at Fed ref, there was a link to the original pitch that called for the shuttlebay to be big enough to house many jetliners or something--so my motto is--when it doubt, make it bigger.

Agreed from a personal viewpoint. From what I remember of people who have made a more detailed study, whose reconstruction of the 11' model has a bearing on how "off" the fit with the sets is. 90% of Treknology is nitpicking though, right? :devil: On the other hand, if they are in disagreement, we all probably want to be informed of the details before we go off half-cocked. Its the difference between purposefully ignoring a fact and being utterly ignorant of it.

Personally, I would probably slightly modify the bridge dome to address issues, but it may not be that simple. The other alternative is to slightly 'massage' the bridge floor plan until it fits, which is somewhat less satisfactory. Either strategy will likely result in calls of 'heresy' from competing camps based on what they consider more sacrosanct (the model or the set). For myself, I'm a practical man, and I'm all for a compromise that gets us closest to both 'representations' of 1701 (interior and exterior) being 'nearly' accurate and working for a 'real world' ship. Other people will have differing agendas.

But ultimately, the conflict between the model and the sets (and the description & 'plans', inadequate and contradictory though they are) will only rear its ugly head in a few choice locations. Reasonable changes to either (or both) will resolve the problem, but the result is conflicting, slightly different, and oddly personal conceptions of the ship for which people will fight to the death. To which I say, "Can't we all get along?"

(I've been tempted to do this on my Jaynz models, just to see if anyone would notice.)

My own perspective is that, while it is true the 'inline' orientation was changed largely for cinematic reasons, what we see on screen for the turbolift is the orienting feature of the bridge set and the turbolift shaft on the model shows us how it relates to the rest of the ship, thus the bridge is... rotated. A simple (and elegant) solution for a simple man. :beer: With sensors, artificial gravity and inertial dampeners the bridge could be upside down and backwards and it wouldn't make any difference to what we see onscreen, so a little rotation so the Captain can keep an idea of who is sneaking onto his bridge late for their shift is alright by me. :techman:

But others disagree, and have their reasons. IDIC.

Amusingly, the deck heights shown in the ship diagrams match the hard line on the walls just above the doors. We can pretend that anything above that 'on the sets' are actually not really there. ;)

Sorry, which diagrams? TMoST, BoGP...?

Speculating blindly... I suppose its entirely possible that the inter-deck spacing consists only of a deck plate of around an inch or so... I've assumed about a foot to allow the running of conduits and what-not, but that is an assumption. For what its worth... It could be a combination of both, with some decks having thick protective or 'conduited' bulkheads and the remainder being relatively thin and functional.

That means you've got to include likely mechanicals for such a ship and a believable hull structure.

My understanding is that the bridge was built 1:1 and the "real" size of the ship was downsized about 10-13%, so my speculation would be the bridge ended up being unintentionally "over scale". Are there plans showing an oversize Bridge (I think FJ and FASA had such, but I assumed those were an error followed by... excessive borrowing)??? Which is I think the opposite of what you were saying. I think I'm misunderstanding you here, and you are actually suggesting an under-scale bridge that conflicts with the studio model... However, I reserve the right to be absolutely wrong. :vulcan:

I think people have researched the Bridge's scale, but my recent drive crashes haven't helped my access to archived information. I would love to hear discussion from more of the researchers on their findings: i.e., a 'state of the bridge' report on the subject from all 'department heads' so to speak. Even in its own thread.

^^ I rather liked how FJ had a service space between the bridge and the outer hull. It doesn't have to be exactly like that, but I don't see the bulkhead just behind the stations as being the outer hull. I see it more credible if there's "stuff" between the inner bulkhead behind the consoles and the outer hull.

It creates a double hull, which obviously is more battle-rugged. Clever man that 'militaristic' FJ. :devil:

Of course, when they've blown out a TNG Bridge wall (Nemesis only?) I don't remember it having a visible exterior area. Not that I have paid that much attention.

My personal opinion is that while the the topic is related to the bridge size/location, going there opens a different can of worms, and we already have a large one open. In short, it deserves its own thread (and I would guess there is no shortage of them looking into the past). "Nothing is new under the sun" is a Treknological proverb also... or so it seems. To summarize, while sinking the bridge generally vaporizes all bridge 'fitment' issues it also allows you to do almost anything else you would like... as long as you don't mind sacrificing more internal volume to simply service the bridge 'support systems'.

As long as 'we' can't decided on the definitive size of the ship other than to say that its somewhere between 940m and 1080m its not clear that the 'Bridge Sinkers' have a dog in the fight. If we fix on a size of the ship, and if we decide on a 'correct' reconstruction of the shape/size of the bridge dome on the 11' model, and if we then find one doesn't fit in the other, and if one rules out modifying the layout of either to accommodate the other, then there is a empirical argument based on the topic of this thread for sinking the bridge. I'm not saying all this work hasn't been done, its just that its taking us more than a bit off the beaten path (for this thread) to look into it all again.

Or, to put it another way, this approach largely invalidates the one we are discussing. The first approach is an attempt to estimate the size of the ship based on fitment of the Bridge module (or the lack there of) and subsequent 'upscaling' of the ship to make a fit. In contrast, 'sinking' the Bridge more or less eradicates the fitment issues (if they exist), and therefore invalidates the scale comparison attempt.

BTW, the weather (and consequently the roads) isn't exactly great here so I'm likely to be dropping in and out of the discussion from time to time (there's no useful internet off the beaten track where I live, so since broadband won't come to me I have to go to it).
 
^^ As I understand it film and television productions have long been known to build sets at 9/10ths (or less) scale. Not only does it save space and money on materials, but it also allows actors of smaller stature to appear larger onscreen. And many actors over the years have been of average or modest height. For example Sylvester Stallone is only about 5'-7" and yet he looks distinctly taller onscreen. And he certainly isn't the only one.

The exterior mockup of the Galileo shuttlecraft was only about 20 or so feet long when we were to understand the craft was supposed to be at least four feet longer. That's also why it was designed with elements of forced perspective to it so that it would look somewhat larger onscreen (from certain angles) than it really was.

The TOS bridge and other sets may well have been built at full scale yet it's also possible they weren't. And note that William Shatner is only about 5'-7" or so yet does indeed look taller and larger onscreen, admittedly partly due to the lifts he wore in his boots.
 
The bridge was about thirty feet in diameter, with the turbolift alcove sticking around six or seven feet out from that. With the pilot dome clocking in at around forty feet, the issue of whether the bridge can face forward is rather moot, at least as far as the pilots are concerned. That just leaves the issue of what happened when the ship was refit prior to formally assuming the five-year mission.

I say the dome was lowered halfway, with the only sacrifice being that circular briefing room.
 
I for one have never been swayed by the “bridge is safer” argument as justification for lowering the bridge inside the dome. Because we should remember, the Enterprise was never primarily intended to be a battleship -sure it could defend itself and/or federation interests if called upon to do so- but it was not expected face battle on a regular basis! If safety was such a concern to either MJ/GR or the hypothetical Starfleet engineers, why is the bridge where it is and not buried deep in the hull somewhere? The answer to this question is obvious, “this is what the auxiliary control/battle bridge is for.”

Likewise, the vulnerability of the exposed T/L housing outside the dome is also mitigated by the above considerations, and by assuming the “docking port” function, neatly explains why it is exposed in the first place.

As for the insufficient dome size or height on the 11 foot model, Shaw has confirmed a long standing suspicion of mine, that it is the size it is because it is essentially what was left over after the three rectangular lights from the second pilot dome were removed by trimming them away from the bottom of the then larger pilot dome. Thus, what was left resulted in a somewhat “lower profile” for the dome and T/L housing, than perhaps would have been otherwise considered ideal. In other words, if it had not been for the necessity of removing all vestiges of the rectangular lights, then less material would have been removed and a slightly taller dome could/would have most likely been opted for?

It is for the above reason (mainly) that I believe that we should not be beholden to the exact size or shape of the 11 footer's bridge dome when contemplating the Ideal fictional starship and the consequent bridge fit issue.

And as far as the overall length of the ship is concerned, 947 feet is within acceptable tolerances, it might be 940 ft. or 950 ft. but it’s certainly not 540 ft. or 1080 ft. We may not know the exact length for certain, but 947 ft. is a close enough approximation and gives us the much desired wiggle room, fair enough?

Regarding bridge placement rationale in-universe, we probably have to start by deciding why the bridge needs to be on top of everything before we start discussing the reasons for moving it farther down.

In today's and yesterday's vessels, the bridge positioning is for the ability to see far (the horizon is farther away if the bridge is up high) and around (the various deck gear of the ship gets in the way unless the bridge is raised) and close (the bridge "bridges" the two sides of the ship so that one can monitor those sides, all the way down to the waterline).

Visibility from a starship bridge isn't good, though, because the saucer gets in the way. But we have these big sensor domes on both sides of the saucer, fairly ideally placed for visibility (assuming one can't get rid of the saucer, and must minimize the number of sensor emplacements). Perhaps a bridge is ideally placed as close to a sensor cluster as possible - mainly because there's no other criterion for its placement, as no place offers better protection than another against Trek weaponry, and people on the bridge need not physically interact with anybody or anyplace else. Why not minimize the distance between sensors and their displays, then?

Moving the bridge would then be rather naturally explained: every time the ship gets new sensors, the top and bottom domes (plus the one near the shuttlebay) need some readjusting. For all we know, the domes are actually on moving jacks for quick adjustment to the newest sensor needs, and the briefing room in "The Cage" was an impromptu utilization of space made available by the jacks being in the up position. That'd nicely match the "collapsible" nature of the room's meager "walls"...

Basically, the bridge wouldn't be placed where its strict requirements necessitate: it would be shoved wherever this facility of few requirements (and perhaps secondary import) would best fit... A bit like the bridges of seagoing ships (essentially a variant of the crow's nest) originally.

Veering off topic, as predicted... :rommie:

Yes, placing the sensors adjacent to the bridge would give a fractional decrease in the time to relay data. Assuming that the data first isn't rerouted to the ships computers... unless they are also between the bridge and the sensors. In any case, the human component would be the slowest. So we would have to be talking about automatic systems (for the difference in signal routing to make any real difference) for priority missions (defense of the ship against great danger). So we could hypothesize that there is a smaller priority computer system overhead that makes snap judgments about raising shields, etc. prior to informing the 'slower' carbon units below that this was necessary. The Klingon surprise attack in Day of the Dove might be an example of it in action, if memory serves (can't check the episode).

My own hypothesis for bridge location has to do with damage repair and upgrades. Essentially, replacing the bridge module merely requires unsecuring it, popping it off, popping a new module on, and securing it. Oh, and connecting the hard links (which hopefully are also plug-and-play). Other less vital control systems buried in the ship are less likely to be damaged and less likely to be upgraded so they are not targets for priority "full-replacement" service. The hypothetical double-wall arrangement around the bridge with the sensor module above essentially adds "padding" to make it about as secure as any surface feature of the ship. In TWOK we see Reliant's sensor dome take a direct hit and, while the effects are pretty dramatic, the bridge itself is largely structurally intact (i.e., no explosive decompression, no complete obliteration).

In the 'game' Star Fleet Battles power surges rather than massive localized explosions are the typical causes of damage during combat. Whether one considers this entirely accurate, we tend to see a lot of 'surge' type damage (consoles exploding, systems temporarily being down, rerouting power and control, etc.) during ship battles and major structural damage tends to only come towards the very end. The point being that control centers buried in the heart of the ship would be as susceptible to these as the more exposed primary bridge.

As to the topic at hand, I agree with TM that 947m sounds fine... even if it doesn't agree precisely with any particular schematic or plan we can dig up or even if it doesn't match the proportions of the scale model. The plans, the model, are all manifestations of the concept, and the clearest communication of the "official" concept is the measurements given in TMoST/Writer's Guide. Its easier to write something down correctly and/or revise it than it is to fully revise a drawing or remake a model.
 
947ft. is fine enough if you're satisfied with something that sounds about right. But if you one of us who would like to get everything to fit together in an integrated way that results in something that at least seems credible then you're not really beholden to that figure since it's never definitively established onscreen.

947ft. is as "official" as you're going to get as far as offscreen sources are concerned. Otherwise it's still an open question waiting for someone(s) to define more specifically.

In similar vein the TOS shuttlecraft seems to have been established as 24ft. LOA by one spoken reference, even though the visual onscreen evidence contradicts that. After a lot of effort to resolve the inconsistency I'm convinced a "real" TOS shuttlecraft is at least 26ft. LOA. And even if someone were to convincingly prove the Enterprise is easily 1080ft. LOA then I wouldn't be inclined to change my opinion about the shuttlecraft's length because accommodating it (and a total of four of them) within the ship's hangar facilities was only one of a number of considerations dictating the size I arrived at. Another primary consideration was reasonable ease of entry and exit regarding the step-up height dictated directly by the nacelle diameter and consequent centerline height off the ground. Also of prime consideration was having manageable internal ceiling height. For me those three aforementioned variables were the prime considerations in determining the craft's eventual size.

And so with the Enterprise I think the bridge issue is the main determining factor. Deciding that and then keeping the remaining exterior proportions as shown onscreen will give you a more definitive figure that's actually based on solid and thorough thinking. It most probably won't get any printed references rewritten, but it will be more definitive and more credible.
