The SSB was the Castor IVA-XL, a stretched version of the Castor IVA used on the Delta II 6000-series (itself a version of the Castor IV used on the Delta 3000-series except with HTPB instead of PBAA):

Yeah, the Thor configs were the first things I worked on so I've been meaning to come back to them. Fortunately by keeping parts on a spreadsheet its easy to adjust mass/propellant and keep track of the effect it has on other variants. As for panels, I was thinking of just a thin, white, quarter-cylinder decoupler: four of them wrap all the way around Centaur and they all blast off when you stage. A white quarter-cylinder part would work fine, since the decoupler can always be added manually.They don't make a big difference in RO, but they weighed about 600 kg and separated just after booster pack jettison. It's not a big deal at all, just saying its the only thing on my parts wishlist I've been simulating them with a procedural interstage, which works just fine except for the interstage base not matching Centaur very well (here I'm using a KW proc interstage, since it matches closest): Test. Now that I think about it, I can probably just add proc interstage nodes to a version of the Centaur base itself to get the same result

BTW the RO configs for BDB are coming along, there's a lot to go through though! So far I've got the Atlas Agena and Atlas Centaur variants down. I've been using a spreadsheet to keep track of the parts and which variants use them. The scope of BDB is pretty awesome; it'll be possible to recreate almost any Thor, Delta, Atlas, or Titan variant that ever flew! The only thing I could ask for in terms of realism are some kind of jettisonable insulation panels for Centaur:

The GEM 40 was offered with TVC, but the version used on the Delta II didn't use it. The GEM 46 had TVC on the Delta III (3 of 6 ground ignited used it, the other 3 ground ignited boosters and the three air ignited ones used fixed nozzles), but TVC wasn't used on the GEM 46 when it was used on the Delta II Heavy. On the Delta IV, two boosters use TVC and the other two (if used) have fixed nozzles.

Looks amazing! My preference is getting Agena parts sooner rather than later, I'm practically dying to make configs after all this build-up

RealFuels supports thrust curves. I created a spreadsheet to generate curves for KSP, here is one based on the SRMU.

That looks familiar... can't really tell if it's angled but looks like it could be.

Keep in mind that that's a schematic of the Agena Target Vehicle, a standard Agena D wouldn't include the part labeled Probe; the avionics would be in the part labeled Rxn Wheels. Combining them doesn't change much though: Content: Agena D, detail Agena Telemetry Module + Aft Section The standard Agena D featured an open truss in the aft section, to which mission specific modules could be attached, such as the ATV's Secondary Propulsion System, solar panels, or subsatellites. I don't know how much KSP would like the collision mesh though: Content: subsatellites and other uses for Aft section truss One nitrogen tank was standard, additional tanks could be added if needed so making them surface-attachable makes sense, or one could just be included in the truss. The engine ran on UDMH and IRFNA, so it'd be standard liquid fuel/oxidizer, with monopropellant for the nitrogen ACS. Content: ACS diagrams aka three-way valves

A few illustrations to clarify: The secondary engines you're referring to are the nitrogen ACS thrusters, and the part that necks down is the aft section? Or the tapered adapter starting at Station 384.0?

It's Agena, not Angara.

Really? Is this happening with the configs I just uploaded? I'll do a clean install and figure out what's up. Edit: D'oh, silly error: left out the last few lines of a config. Fixed. Ctrl+A, Ctrl+C, Ctrl+V, my three nemeses.

GitHub; I've removed all the non-BDB content so it's easier to merge just the BDB configs without having to search for them with everything else. It's nearly ready to be merged into RO itself, just needs manufacturers and descriptions (and maybe a spreadsheet - it's possible to recreate a LOT of Atlas, Thor, and Delta configurations with the parts you've created! So far I've focused on Atlas-Able, Thor-Able, Thor-Ablestar, and Atlas I-III, with Atlas G-Centaur next on the list.) So far I've managed by resizing and gluing together the various adapters to fit RO tank sizes. I'll PM you the adapter sizes, but no hurry. As an aside, have you considered jettisonable insulation for Centaur, as used through Atlas I? I've been trying to come up with a way to simulate them with no luck so far.

I've updated the Realism Overhaul configs to include Able, Ablestar, Thor, and Vanguard; they're available from the same GitHub branch as before, or, more conveniently, by themselves. Definitely still a WIP, but GLOW, payload, and dry mass are good, and almost everything fits together properly (jury-rigged adapters for RO diameters) except Vanguard. As always, awesome work and I can't wait to get to play with Agena

[quote name='CobaltWolf']BDB mostly focuses on 'Murican inspired rockets, but I suppose eventually I'll run out of those.[/QUOTE] If you ever feel like you're running out of Atlases... there's [URL="http://www.b14643.de/Spacerockets_2/United_States_4/Atlas-Vega/Description/Frame.htm"]always[/URL] [URL="http://www.spacelaunchreport.com/atlas-vega-card.jpg"]Atlas-Vega[/URL], the cancellation of which drove GE out of the rocket business :)

[quote name='Autochton']The word 'honor' means 'females' in Swedish. Turkish delight, in Turkish, is 'lokum' - which means 'latrine' in Danish. Language collisions happen, even extremely rude ones.

NASASpaceflight.com [URL="http://www.nasaspaceflight.com/2014/03/sls-positioning-arrm-europa-missions/"]reported[/URL] that SLS's Dual Use Upper Stage was renamed the Exploration Upper Stage because DUUS apparently sounds like a Japanese profanity, though no Japanese speakers I've mentioned the story to could think of any particularly offensive homophones.
