accurate Oberth-Class schematics

[Reverend]

The way I see it the secondary hull is a support structure for a variety of internal modules that can be accessed through those large dark grey panels that I'm choosing to call roll up doors.
Sort of like this.

As for the shuttle bay clearance, that is a problem. In fact the more I draw this the more I believe the model builder/designer intended it to be more like 250m than 120m. For now I'm going to say that the aft doors are mostly for cargo while shuttle access is usually through the dorsal bay doors.

 

[Bill Morris]

That's looking better each time. Maybe some kind of escape pod can be stored inside, to be launched through those small doors.

 

[SonicRanger]

Will the Grissom's bridge even fit under that dome? And how do the windows fit with your decks?

 

[Reverend]

My current thinking is that the escape pods are berthed under those large dark grey panels around the dome.

Will the Grissom's bridge even fit under that dome? And how do the windows fit with your decks?

It seams to fit ok. As for the windows, I have no idea as of yet. As I said I'm pretty sure the model was built to look twice the size it's supposed to be.

 

[BolianAuthor]

Looking good so far. I assume given the small size of the ship, and the size of the escape pods, they would be larger, "communal" escape pods, like the Saratoga's, and not two-person pods, like the Galaxy-Class?

 

[Reverend]

Since those sections are modular, the ship can be outfitted with as many or as few escape pods as necessary. As for the type of pods, since I'm estimating the class was originally commissioned in the 2180s/90s the original pods would have been basic boxes with engines and life-support, but yes, later refits would include the same 6-8 person ASRV's as the Galaxy.

...Or perhaps older ships featured very high-tech lifepods, while modern ones can make do with simpler things because modern search-and-rescue services function quickly and efficiently?

The three openings at the lower level of the saucer, at bow and to port and starboard, are suggestively shaped like the trapezoids openings in the TOS shuttle hangar miniature/set (and its Ent-A and K-7 counterparts). I'd love to associate an airlock or hangar function with those, even though I agree that the main "payload areas" of the ship should be where you put the yellow in your drawings. The USS Thagard idea of having large hangars behind those doorways doesn't sound too bad, assuming that they would actually serve as hangars in exceptional circumstances only, and would normally be utilized for storing consumables, experiments and other such stuff for the supposed long duration missions.

One doesn't need to accommodate too many crew aboard the ship when we know from TNG that seven is plenty for operating a modern Oberth. The other references to up to 80 people aboard would apply to ships that have expanded habitable space in the ventral pod. So what I'd like to see is a ship that can serve a science or supply function even with the pod detached, but gains extra abilities when the pod is attached; the saucer might thus have three airlocks/shuttlebays which in practice do not serve in that role in modern ships with permanently carried pods.

Well we know from the TNG tech manual (and Mr Scott's Guide, if you like) that the newer escape pods are much more self sufficient than the previous models. Though to be honest I think the only major innovation of the ASRV is the gaggle mode, but then that only really becomes a benefit on a ship with large numbers. Other than that I think the only real difference between 22nd century pods and 24th would be in terms of recycling efficiency (replicators replacing synthesizers) and a general miniaturisation of the power plant and computer systems allowing more room for either extra people or more survival gear.

 

[Praetor]

I've been talking with Reverend and LCARS24 to create a MSD for the LCARS project and Reverend suggested I post what I have here to get a reaction from everyone else. The labels are not final, they are just for discussion.



I basically agree with all of the conclusions that Reverend reached, except I go for a just slightly bigger 160 meter ship a la Jackill. Modularity really explains a lot about this design, from the 'roll up doors' to why these ships seemed to last so long in service. Here, presuming this is the Grissom, the ship has a large planetary sensor array in its 'swing bay' in the pod and probably science labs under the saucer module bays. I've omitted a bridge turbolift in favor of stairway access since the ship is so small. I honestly don't recall if we actually saw markings on the Grissom bridge to indicate for sre that the door there was a turbolift, so for now I'm ok with that.

The 'science ops corridors' are meant to correlate to the Vico as seen in 'Hero Worship' (presumably there are other such matching facilities on deck 4 that you can't see on this cutaway) and there should be an adjoining lab nearby that would go with the sets seen there, if anyone wants to pretend the Vico is this small. Although not shown here (and perhaps I should revise to include it), I'm guessing there's one transporter room in each section, which could be hard-wired for emergency transport between sections. Otherwise, sole access between sections would be by ladderway. I'm thinking there are some science labs below in the pod to take advantage of proximity to the sensors and computer core (which I rationalize needs to be near the sensors to process all their data - no doubt a smaller processor somewhere upstairs to handle command functions if the ship separates.) I don't see why a science crew might not bunk down below for extended research missions, and I think the civilian science crew are a good suggestion, maybe even aboard the Grissom.

Regarding shuttles and other auxiliary craft facilities, I could also see the swap bay in the pod being fitted with a hangar deck that could lanch in two directions and accommodate the larger shuttles better.

I think a 2180s U.S.S. Oberth makes perfect sense too, and might help explain why the shuttlebay seems a bit tight, if it originally eqipped ENT-style shuttlepods. I also think that it's entirely possible Starfleet pulled a K'vort and the Vico and Tsiolkovsky are of a bigger, Oberth-II class (call it whatever you want) which I have started roughing out and may finish later.

Well, thoughts everyone?

 

[Sarvek]

I really like it. It looks like you did your homework on this one. The internal arrangement seems to make sense, but I still like Reverend's cross-section. The one that you have done would make a great MSD. I hope that Reverend would go back to doing some exterior profile views and complete his internal cross-section.

 

[Praetor]

Thanks! I agree wholeheartedly that I hope we can convince Reverend to finish his plans.

 

[Reverend]

I have been tinkering a little since you PM'ed me. I'll post something when I have something marginally significant to show for it. For now I need to polish off the details on the saucer and rough out the deck plans for the secondary hull. I think I have the primary hull more or less sussed.

I'm with you on this.

 

[Bill Morris]

Okay, Praetor's Miranda is all done and ready to include in the LCARS 24 library:

And for the Obeth, I've edited this one somebody gave me to try to bring it into line with Praetor's and Reverend's ideas, figuring 150 or 160 meters overall length, even though that's tight for the shuttles, and taking into account the discussion at Ex Astris Scienta. I'd like to call this one done and move on to the next group of ships.

The others most of you have already seen, but here's a gallery of them, and all the new ones will be in this style:

[Santaman]

You know what I find most amusing?

The Oberth is about the smallest ship in the fleet and also the cause for the greatest discussions and ingenuity to make things fit.

I can't wait to see the updates! I think by far you've already defined the class whereas before it was just, 'oh, they didn't know what they were doing.' The innovations you've made here have really made the design seem logical.

Edit: here's a revision of my MSD to line up a bit more with Reverend's plans. Still not totally happy with it, but much happier than I was.

I've always thought it would be nifty - and in line with your ideas of modularity, if the lower pod could be entirely detached, and swaped out for other things, such as, say, a long cylindrical pod making the ship a cargo carrier. (A cylinder like we see on the TOS cargo ships in, iirc, the orignal TOS Trek manual.)

And you could probably imagine it accomidating several other swapable mission-specific types of pod as well.

I tweaked some line-drawings I found of a Oberth to make a couple of really rough sketchs of what an Oberth would look like with a cylindrical cargo pod in place of the...whatever the movie/TNG pod is...but I don't know where I saved it at...they only problem I encountered was that you would have to either widen the gap between those...whatever the bits are connecting the top of the ship to the lower pod... since it could only accomidate a rather narrow pod in the space it has between them now, or you could design some sort of narrower interface sitting on top if a larger pod that they could connect too.

^In that last one the circumfrence of the "cargo pod" is just a bit too large.

 

[Praetor]

I would think that there would be some kind of magnetic/attachment pod that would fit in place that the pod would attach to, not directly to the struts themselves.

Like this ?

Why yes indeed!
