All About the Eclipse Star Destroyer

Sorry if this has already been posted, but if the Axial SL is 2/3 as powerful as the DS SL, wouldn't the recoil send the ship flying away at relativistic speed ? If the ship has typical capship accel, it is less than 5000 g... so it probably wouldn't be able to compensate for this.

Since this didn't happen to the Death Star, we can conclude that they can compensate for it. My guess would be with the inertial compensators.

Uh, the Death Star has orders of magnitude more mass, and the same huge engines which must be able to acclerate that mass to help it.

The Eclipse has neither.

It also has a magnitudes more firepower, since its clear that the 2/3rds quote doesn't hold water. Doesn't matter anyway, it's the same as asking why the Executor doesn't fly backwards from firing its turbolasers. Or sideways, when firing a broadside. Or say a smaller ship like a Carrack which have HTLs. Obviously, engines aren't the only answer, though it is probably part of it.

I am sure that when firing the sl from the Eclipse, you would have a light recoil but nothing that would damage or even fling the ship backwards.

Are you all afraid of numbers to back-up the refutations?

Techno_Union · Post by **Techno_Union** » 2004-01-19 05:15pm

I do not have any numbers to support my claims but one would think that a slight recoil would happen.

nightmare · Post by **nightmare** » 2004-01-19 11:29pm

U = 1e28J
c = 1e8 m/s
p = 3,33e19 kg

Lenght = 17500
Wdith exkl spine and bridge = 12680
Height exkl spine = 3320

Assuming iron density (7780 kg/m3), 95% air and a half-square section, m = ~1.45e14 kg.

a = ~50000 m/s2, so F = 7,25e18 N.

That's should make a very noticeable recoil. Nor does it apply to broadsides. However, I did speak hastily. I forgot that the now canonized complex mass fuel theory means all results are off. The mass should be so great that recoil will be negligible.

You provide no numbers of your own, yet you criticize HIM for a no math mentality?

Ender alone has several threads on recoil and the Death Star and related subjects. Any one making a claim can throw out a some keywords and search. Excuse me if I don't want to go do others' homework for them when they're claiming things are the other way. We all have equal search abilities.

Would it be possible to refit the Eclipse with chyrstilline(or however you spell it, sun crusher armor) armor, or molecular armor? PRice would be a huge factor but would it be possible?

It is certainly possible but armouring a 18 kilometer long battleship with this exotic armour would be extremely expensive.

Techno_Union · Post by **Techno_Union** » 2004-01-21 05:03pm

Ya the price alone would be staggering but it would be a huge advatage to have one of these two armors. Would it be possible to incoporate the two armor types into one?

Also a weird idea, would it be possible to have a resonance torpedo launcher in the Eclipse which would be an exact replicate of the Sun Cusher's?

Yes (and its quantum-crystalline armor.) but why bother? Its armor and shields were strong enough to allow it to ram warships if it chose already.

If someone asks me for evidence of something I am referencing (and it does happen), I generally provide the refernece (I'm even capable of doing calculations if required.) I don't generally expect people to read my mind and know what I am talking about.

Were the Eclipse's shields able to withstand a supernova? That is why I wanted to know about refiting it with the other armor.

I'm seeing a fault in logic here. Explain this in laymans terms for me, i'm a blond secretary. But unless i'm very much mistaken the Eclipse is much small than two thirds of the DS. So saying that the Eclipse can handle a SL 2 thrirds the size of the DS2's seems to a wee bit off to me. What is the size ration between the DS2 and the Eclipse?

Rogue 9 · Post by **Rogue 9** » 2004-01-21 08:42pm

Try this. Its a site for scaling sci fi starships. The size ratio will be a little off because he uses the 12.8 km figure for the Executor, but when compared to the Death Star the size difference is negligible. If you use Internet Explorer you can drag the images next ot each other for comparison.

The Ecilipse superlaser is much weaker than the 2/3 DS2 superlaser value. While the DS2 superlaser generates thousands of times the energy needed to destroy a Earth sized planet the Ecilispe superlaser only glasses the surface and destroys continents. It is similar to all the firepower of a BDZ fired in a single blast.

Then what was the point in the Eclipse, surely it'd be cheaper and easier to build a few normal ISD's.

Pure terror and theoretical indestructibility, at least not by a normal fleet action.

A few hundred ISD's rather.

Rogue 9 · Post by **Rogue 9** » 2004-01-22 08:19pm

My point still stands. Add to that the fact that the Emperor rode that thing and that an ISD is a lot easier to destroy than the Eclipse and then factor in Palpatine's ego and you have all the reason you need.
