Ship sizes for some classic ships ...

Some classic Trek ships, that is!

Mainly, I was hoping there was a good resource to figure out what the displacement (i.e. volume) for the following TOS ships:
- Constitution-class cruiser
- D7 Battlecruiser
- Romulan warbird
- Tholian ship
- Shuttlecraft

I don't need (or really want) anything exact. Just something to two significant digits. In either cubic meters or displacement tons.

Thank you in advance!
 
There was a thread about the Enterprise somewhere on this board somewhere. Try searching. From memory I think the constitution class was scaled to about 100,000 tons.

The Galileo looks to be around 10 tons..tiny!

According to Franz Joseph's Star Fleet Technical Manual, the original Constitution-class heavy cruiser is 190,000 deadweight metric tons. There's no specs on the Shuttlecraft, but it seats 7 and is about 6m long, 2.5m wide, and 2m high.

According to Ships of the Star Fleet, Volume One, the Constitution-class is 181,000 metric tons standard (177,000mt light, 185,000mt full load).
 
Const. Class: based upon measurements of the SFTM by FJ, 167001kL or so... just shy of 12KTd. But note also: it's a bit too small...
Nacelles: 153.619x (13.2 to 17.3) approx 28563kL or 2040Td each.
Saucer: 127.1x29m using some conic chunks and approximations, 46158 kL, or 3297 Td
Sec. Hull: approx 56017kL or 4001 Td
Neck: 2700kL or 193Td
Struts 43m x2.5m x13 approx 2500kL or 178Td Each

The SFTM DN saucer is larger - 123000kL or 8785Td... making it Large Saucer +1.5 necks + 2 struts +3 nacelles +sec hull or about 19500Td total.

Shuttlecraft: same source. bounding box 2.448 x 4.312 x 6.928 = approx 73.13 kL - about 5.2 Td.the body is actually closer to 33 kL, the nacelles 0.4x5.3m are approx 0.67kL each, which gives a volume of about 35 kl - about 2.5Td... yes, more than half the bounding box is empty.
 
It is kinda a mix. MGT doesn't provide any new TL definitions for 16+, so I pulled out my trusty old TTB. In it, it gives:
TL 16: Disintegrators
TL 17: Anti-matter, self-aware robots
TL 18: Personal disintegrators.
MegaTraveller adds that White Globes are TL 20.

So, it just doesn't match up very well. Star Trek doesn't really have self-aware robots (prior to Data, who, with Lore, is virtually unique), but has force fields (aka White Globes). Given that phasers are essentially disintegrators, and that anti-matter is a mature technology, I would go with TL 18, for at least TOS and the movies. For TNG, DS9, and Voyager, I can see 19 or 20.

What tech would Star Trek be at? 17 or 18?
Click to expand...

It varies. Both by Ruleset and by area of tech.

Using MegaTraveller...
Personal Military: 19-20 Disintegrators
Heavy Military: 17-20 Disintegrators & White Globes
Computers/Robotics: 14-15 No true AI, but some emotion sim and pseudobiological robots.
Commo: 17-18 - Pocket holovideo, pocket meson comm
Env: 19 - Terraforming whole worlds, but no moving worlds.
Medical: TL 15. pretty firm... no brain transpalnts, nor memory transfer.
Transportation: TL19 Gravitics, Matter transport Regional range.
Space Transport: TL18 - Antimatter 1Mw/L, Mature Warp Drive at J6 Equivalent or faster.
Energy: 18 Antimatter

Using MGT, instead...
Armor TL14 - no evidence of Battle Dress.
Augments: TL16 by TNG, probably TL15 for TOS
Commo: TL13+ Due to limited AI.
Medical: looks to be TL15
Robots: TL15 but underused
Sensors: TL16 (combined functions of several TL15 handheld sensor types in the tricorder)
Weapons TL15+
Vehicles: TL16+
Starships: TL16 TOS, much higher for TNG+, due to Antimatter & shields, but can be as low as TL14 for early TOS for all other ship tech. Use Meson Gun as phasers.
 
We'll see what MGT's take on this subject is when they release their Traveller version of Prime Directive, and their Star Fleet Universe version of A Call to Arms.

Bounding box (of anything) is the smallest box the object can be fit inside without bending, folding, or otherwise altering.

In some understandings, it's allowed to be at wonky angles (for example, an SFB lyran ship can have a smaller bounding box if your tilt it in relation to the box), while in others, it is with normal XYZ axis matched to that of the box.

Usually, this means the box with the same overall height, overall width, and overall length as the object.

Yes, I know what a bounding box is. I was asking what ship you were referring to regarding the 80%...

Why didn't you ask that in the first place...

Constitution Class. And I'm pretty certain it's more than that.


127.1 x 288.6 x 72.6 = 2663044.956 kL = 190217.49685714283 Td

0.06308567927908462 filled if 12000Td is accurate (it's accurate enough, but still pretty damned sloppy, since I used an approximation rather than full conic extension methodology for the various partial cones — average the end areas and multiply by length. Plus, almost all of them bow outwards.)

More like 93.7% empty for the const. Class.
 
Hmm, I was surprised at the low estimates of the shuttlecraft tonnage.

The shore boats IMTU that were based on the original Galileo craft are 10dT, (they have to be, to get the requisite couches in), but this picture:
http://www.retroweb.com/trek/dvdcap_kirk&spock_w_shuttlecraft.jpg
indicates that Aramis' dimensions are about right and I would estimate from the picture a displacement of around 3dT.

The memory plays tricks - especially after so many years...
I'll still keep my 10dT shore boats, though. :)

I did ask:

You said, 80% of the bounding box is empty space...
I asked: The bounding box of the Trek ship?
:)

Sounds about right given it overall shape. A constitution class basically consists of 5 cylinders, a small box and a saucer spread out widely.
 
Well, do realize that the set for the interior of the shuttle was larger than the set for the exterior of the shuttle. In other words, the two sets were incompatible. So, I guess you have to pick which one you want to go with. :)

Wait! If the shuttlecraft is 3dton (or perhaps 4dton if the internal dimensions are used), that would make the shuttlecraft the Star Trek equivalent of the air/raft! Well, an enclosed air/raft, anyway. I wonder what an open shuttlecraft would look like ...
