ok the scene where the falcon exits hyperspace on top of where alderaan used to be after it was blown away by the death star. shortly after we see a tie fighter zoom past the falcon and starts flying towards empty space, and within a minute the death star is visible, even though before it was just a speck in empty space..

what kind of speeds are we talking about here ?

I don't know for sure but IIRC the DS didn't move since Alderaan was destroyed it was sitting about six planetary diameters out from the planet so i think that they weren't going very fast.
keep in mind thought that the falcon was being pulled by tractor beams most of the way.
Someone correct me if i am wrong.

If im not mistaken they get to the DS2 ROTJ very fast also

How is going fast a "dillema"?

I've seen references in books to the Millenium Falcon doing ".5 sublight". I've assumed that means .5 the speed of light while not in hyperspace.

If so, half the speed of light is about 90,000 miles per second.

They were exiting hyperspace and had timed their rundown speed to land them almost on top of it. (Those Sullustan navigators are good at what they do.)

Then those references are wrong. The Falcon's hyperdrive is rated at .5. That's a class .5 hyperdrive. Hyperdrive systems are rated on a class system according to their speed. Class IV hyperdrives are the slowest and are found mostly on civilian freighters and transports. Class I hyperdrives are the best you can get and are found on military vessels. Through uber tweaking and illegal hot-rodding Solo was able to get his ship down to .5.

Doesn´t a VSD have a class 0.5 hyperdrive too? As well, as the Acclamator?

What hyperdrive-factor would the Galaxy-Gun have.

I don't know the hyperdrive class on the galaxy gun missiles but if i'm not mistaken they can go from the inner core to the outer rim in a few hours.

Fairly certain this is using the other method of calculating hyperspace, which I think Tim Zahn first used. Under this method, the VSD had something like a 0.4, which was actually meant to be slower than point five. I'm not entirely sure where the inverse version (i.e. lower number = faster) came from, but under this system a VSD has a class two hyperdrive. Solo's is the fastest known hyperdrive, with Dash Rendar's Outrider coming in second at 0.75. Most military vessels have class one hyperdrives, some older vessels have class twos.

There is only one hyperdrive multiplier system.

The Acclamator-class has equal performance to the Falcon at .05 past lightspeed, and the Jade Sabre has even better with .03 past lightspeed.

0.5, not 0.05.

And why, then, does Zahn (I think it was Zahn, anyway) say that the VSD's top speed is 0.4, when everybody else and their mother says it's 2? I think he was using a different scale, personally. I'm fairly certain other places have used this scale as well (0.5 being fast, 0.1 being slow, rather than 0.5 being fast, 2 being slow). I can't cite anything presently because A) my Zahn books are 150 miles away, B) my other books are also 150 miles away, and C) I don't particularly feel inclined to rummage through thousands of pages to find one insignificant little quote.

I dunno; actually I'm partial to the .04 VSD; as a small destroyer you'd expect her to be faster than class 2.

In SQ he definitely uses .03 as really fast for the Jade Sabre.

Smaller, but older. And 0.4.

Yeah, I can believe that (0.3), since Jade Sabre is a new vessel, and smaller than the Falcon to boot, IIRC.

I'd assume that the Galaxy Gun's missiles would be faster than 0.3, which is what messenger drones travel at. 0.2 or 0.1 seems most likely.

The Star Wars galactic civilization is, for the most part, in a state of technological and developmental stasis. They do not posess the thirty-year tech rollover periods we do.

Stands to reason that bigger + faster = more expensive, though. And given the era of production, I'm more inclined to believe that they were installing slower hyperdrives in favor of building ships faster and more cheaply.

EDIT: Changed smaller to bigger. Dunno what crack I was on when I wrote that the first time.

It might, and a I stress might, have been a hold over from the period of largely localized fleets. It's possible in terms of manufacturing, support, and logistics that at the time it was a design compromise.

The Victory-class star destroyer Mark I was a long-range destroyer designed and fielded near the end of the Clone Wars.

I'd expect the Dreadnought-class frigate (or as RSD styled it, "heavy cruiser") to posess those troubles, but not the Victory-class.

An interesting fact of Survivor's Quest is that there must have been some Dreadnought-class ships available with long-range, high-endurance hyperdrives to form the heart of the Outbound Flight Project.

Slight nitpick. The Acclamator is slightly slower than the Falcon, coming in at 0.6 according to the ICS.

Oops.

I believe the original question here is about sublight speeds. Try to remember, the relative speeds you see in battles are nothing like the relative speeds you see in normal flight, because the ships' pilots don't have sufficient reaction time or maneuverability to fly at those speeds and not crash into each other or fly out of range. Thus, in combat, acceleration is largely meaningless. Speed is how fast you and your ship's computer can handle. The only time it would matter is in pursuit, which includes exitting a battle.
The AOTC ICS lists accelerations for various craft to range from 25000 m/s/s to 50000 m/s/s. That's really goddamn fast. In 3 seconds in a light fighter you'll be moving at 150 km/s. The DS diameter is 160 km. The speed you see the Rebel fleet moving toward the DS2 at was probably in the thousands or tens of thousands of km/s. They would actually be decelerating for much of the time after exiting hyperspace so that they don't overshoot. Obviously, they planned to come out of hyperspace such that they could be at a nice slow cruising speed when they reached the likely shield diameter; they were able to change direction in the "Pull up! All craft pull up!" scene.

ok so not a dillema

more like curious about the kind of speeds that they're travelling at to reach the death star that quickly.

I thought in the novelisation Han says ".5 factors past lightspeed"...

Does that change things or jibe with this "hyper drive classes" explanation?

Then there's the whole "what does the term lightspeed mean in Star Wars"? It's used onscreen almost synonymously with "jumping to hyperspace." So is lightspeed really c?

Maybe going c is only needed to start the jump to hyperspace?

Jumping to Hyperspace skips over C completely.

As for the rest, it's just jargon.
