[Spaceships] DS-1 Orbital Battle Station
Here it is, the one spaceship that many folks have told me not to toss at them! The original Death Star!

The Ghost Particle beam is the best fit I could find for the Death Star Super-Laser at the specified TL. Boosting it to a one-of-a-kind TL 12^ innovation is also possible. 2. I had a bit of flak from some folks on IRC about using "Particle Beam" for the turbolaser, with folks pointing out obscure citations "proving" that turbolasers (and blasters, for that matter) are not particle beams, despite the overwhelming number of citations in which they are described as such. I therefore challenge folks to come up with a better fit if they feel it necessary. 3. I have not broken down the Habitat section for one simple reason: With 24,000,000,000,000 (24 trillion) cabins, would you attempt it?! :) Abbreviations: T = Trillion (10^12) QD = Quadrillion (10^15) QT = Quintillion (10^18) ZJ = zetta-Joule I don't know whether I'll do the DS-2 Orbital Battle Station (Death Star II); any stat block would be its finished version, not the unfinished-yet-operational version as seen (and blown up) in the third movie. The DS-2 has a diameter of 900 km, or roughly 560 miles, which would be SM +34, boosted to SM +36 due to its spherical shape.

Re: [Spaceships] DS-1 Orbital Battle Station
Looks good. I did the calculations for the size of the two Death Stars a while ago, and got the same results as you, so I think that's correct. I would not call it Streamlined however; the reduced armor efficiency of that option is due to a vessel having a higher-than-expected surface-area-to-mass ratio (due to the long narrow body and sculpted hull segments) while a sphere has, by definition, the smallest possible surface-area-to-mass ratio.
I'm not sure how you're getting 2dx1B for the Spinal Mount. A 1ZJ Ghost Particle Beam should deal 2dx100,000. It may be a typo, or you may have misunderstood the scaling of beam weapons. Of course, 2dx100K isn't sufficient to destroy a planet, even when tripled for an internal explosion; an Earth-sized planet is roughly SM +45, for 100M HP. So it could be that you've just handwaved a hugely inflated damage score to allow it to achieve that feat. After all, even adding the Cosmic Power modifier to the Superlaser (bumping it up to 1 Yotta-Joule) would only increase damage to 2dx1M, requiring five shots to drop a terrestrial planet to 0 HP, and far more to reduce it to rubble. It could be that the weapon is "double Cosmic", delivering 1000 YJ, or 2dx10M, enough to force a death check in one shot. Also, I'd recommend a TL12^ Conversion Beam as a better match for the Superlaser. You really don't need all that much armor penetration; an Earth-sized planet has only DR 2M*, so any weapon capable of damaging the planet will not even notice its DR. All of this means, of course, that the other powered systems have negligible drain compared to the main gun, which is entirely appropriate. I'd suggest bumping up the cost of the Spinal Mount and Reactor by a couple orders a magnitude to represent the tremendous power they can deliver. *I think I based that on a SM +45 Spaceship composed entirely of Rock "Armor". And even that may be excessive, since the crust is quite a thin layer, and the mantle and core may be less resistant to penetration. Last edited by vierasmarius; 07-26-2012 at 05:03 AM. |

Re: [Spaceships] DS-1 Orbital Battle Station
If you want to be fussy, Mike Wong has demonstrated that the Death Star superlaser would have to release 10^32 to 10^38 J of energy to overcome the gravitational binding energy of an earthlike planet (the superlaser didn't just melt or shatter Alderaan, it scattered the pieces so that they didn't immediately fall back together). Add some energy to overcome the planetary shield. Star Wars technology involves gobsmacking amounts of energy. I wouldn't worry about what type of particle the turbolasers or superlaser shoot, since its pretty clear that they don't match our physics.

Also, thanks to tbrock for statting this up. I'm off to compare it against Spaceships and Space and figure out how you did it all. Last edited by SolemnGolem; 07-26-2012 at 08:41 AM. |

Re: [Spaceships] DS-1 Orbital Battle Station
The defenses are supposed to be designed around a direct, large-scale assault, with small, one-man fighters an afterthought. Shouldn't you have more weapons on a capital-ship scale, and fewer tertiary batteries?
Star Wars ships have deflector shields, no? It's a bit bumpy for those one-man fighters to penetrate the one the DS has. The crew/cabins/workstations count seems pretty high. Did the Empire depopulate thousands of planets just to crew the Death Star? |

That Red and Gold squadrons were able to pass through the field with their own deflectors on tells me it the Death Star did not have a deflector shield large enough to cover it. If it was a deflector shield, the fighters would have simply impacted against it and blown up (which happened to a few fighters, at least in the novelization, against the second Death Star when they failed to pull up in time following Lando's realization that the shield was still up, and that shield was generated from a nearby planet/moon). Quote:
As for the cabins, as I indicated in the original post, the habitat section - which included living quarters for the several million crew and civilian contractors on board, as well as the establishments (one owned and operated by an Alderaan native, no less), medical facilities, trash compactors, training areas for the 501st Stormtrooper Division and 181st TIE Fighter Squadron, dianoga petting zoo, etc. - has not been broken down. The Death Star was a mobile city as well as a military installation, after all.

The Earth has a mass of about 6.6e21 tons, which normally gives 1.9e9 (1.9 Billion) HP for a Homogenous body. Using the more generous and realistic HP calculations from Pyramid 3/34 (based on square root of mass instead of cube root) gives 1.2e13 (12 Trillion) HP, falling very close to the amount calculated above. To achieve such extreme damages, you could either arbitrarily declare that the Superlaser is sufficiently powerful, or take a look at another option from Pyramid 3/34, "The Square Root of Destruction". Like the above option for HP, this changes the calculation from cube-root of energy to square-root. A "double Cosmic" SM+32 1000YJ Spinal Mount would deal dDam 9dx10B, or around 12.6 Trillion for a Conversion beam, still a little short of what's required. You need to get into the 100K-1M Yotta-Joule range to reliably vaporize a planet (126-420 Trillion damage). This is effectively a SM+48 to +50 Spinal Mount, and thus requires extreme handwavium to squeeze into a mere SM+32 planetoid. There are alternatives to brute force, however. If the Superlaser could set up some sort of chain reaction within the planet's core, it could perhaps destroy it with a far milder energy output. This is still blatant superscience, but it at least doesn't directly violate the maximum energy density of matter. IIRC, the Sun Crusher (a superweapon that shows up in one of the Expanded Universe novels) did basically the same thing with a star, triggering a supernova. Likewise, a similar concept shows up in Star Trek (the Genesis Device from ST2:Wrath of Khan, and Trilithium missile from ST7:Generations). Perhaps the clearest example of this idea is the Molecular Disruption Device from Ender's Game, which will instantly destroy any object, converting its entire mass into an expanding sphere of annihilation.
