barring passive FTL
Hyperwave Sensors to Dectect Ships in FTL are Passive as far as we know
They are only useful in detecting FTL communications (Hyperwave), and mostly entry and exit from hyperspace. Some models can detect the passage of ships while IN hyperspace, but you cannot attack what is in hyperspace.

Star by Star quoted the Millenium Falcon with "subspace imaging sensors" that Han used to scan some asteroids in the Black Bantha nebula. Its known that starfighterssuch as X-wings, a-wings, etc. have "phased tachyon" detection arrays for long range scnning (SW.com, X-wing entry, and the SWTJ) . Han Solo and the Lost Legacy also mentions Subspace detection gear. Mike's dealt with the FTL issue pretty well on his site anyhow.

Unless starships are constantly emitting FTL emissions (communications don't count, since they can't ALWAYS be using FTL comm), the sensors would have to be active. This is especially true in SBS, where they were used to detect ships that do NOT appear to use subspace (that we know of) and in scanning/distinguishing inert materials.

Granted, but you forgot to mention other ships (fleet battles). Open space battles might be unobstructed, but the majority of conflicts tend to take place around planets.
Second, there is no avoiding a LS weapon, you cannot dodge what would cannot detect.. The beam is traveling at C.... So unless you can detect it with FTL sensor ( remember jamming works both ways) you donot know where the enemy is firing...
1.) Your first point is only true when the distances are close enough that reactions are impossible, or that a ship cannot cover enough distance to get out of the way. Either requires FAR closer ranges than you suggest (not much more than 1 LS),and the latter is likely in the thousands of km range or less.

2.) Secondly, who says they cannot detect it? Han and Leia had no trouble detecting NR firing on Yuuzhan Vong ships in STar by Star (black Bantha nebula battle) and they were WELL beyond visual range. Same goes for Pellaeon tracking the TL progression and effects via sensor from the Chimarea in planetary orbit (Dark Force rising).

And there is this (from armament entry, laser cannon section): http://mywebpages.comcast.net/rcrierie/ ... /SWCh1.htm

"Some lasers can be altered to change their beam color to any wavelength in the electromagnetic spectrum, This allows such vessels to attack "invisibly" (by firing in the non-visible spectrum) to gain initial surprise, but because such attacks can he detected by sophisticated electronic defense systems, this tactic is only of limited effectiveness. "

3.) Any EW effects strong enough to block out the FAR stronger emissions of a TL (can a targeting laser vaporize a large asteroid?) will undoubtably jam a targeting computer.

Even if we assume they CAN'T track TLs, whats that matter? Any intelligent person would know that someone is going to fire on you, its better to be moving if you can to AVOID getting hit. AT tens of light seconds range, you have more than enough odds of avoiding hits if you keep moving. Only an idiot would stand still (and if this is the only thing allowing SW ships to make hits at 10 LS or more, then its going to help alot of OTHERS too.)

At the distances you claim, lag, ship capabilities, and the nature of the enviroment all conspire to make accurate predicting and targeting difficult if not impossible.
Second TL work in batteries ( 2 - 2 gun turret and 1 single, for ISD I) no one single gun is experted to hit.. But it hope that due to the spread a single hit will be scored..
Really? I wasn't aware that a single 200 GT TL hit was goign to breach the shields of an ISD. I always operated under teh assumptions it took broadside-scale salvos to actually generate penetrations (or HTL fire, which are too few and slow firing to adequately cover ALL vectors at the ranges you suppose.)

A single hit or even a couple hits by a MTL does nothing agianst a shielded cruiser or Star Destroyer. That they may only score a few hits out of dozens or hundreds PROVES just how difficult it is (relative to close-range engagements) to land coordinated/concentrated fire.
The fact is in WWII ship were manuevering, and still hit was score, that what Targeting computer are for and firing volleys
WWII ships are not nearly as mobile as an ISD (even if we assume your WW2 battleship can accelerate at 10g's) and cannot cover as much of a distance as an ISD can. Nor does it have as many dimensions to work in. And there are TREMENOUS differences between combat at planetary distances and interstellar ones. The "Fact" that WW2 ships can or can't do something does not prove it is equally feasible with SW ships, or any OTHER ships.

Hence the claim they can engage at tens of millions of km (10-20 LS) is false.
As for EU..

Well let look at Ambush at Corellia.. The MF traded shot at million KM with attacking Robotic fighters ( at a range of 3 light sec)..
And that with his quad lasers, not even heavy turbo laser...
Wow, as out-of-context a claim as ever.

1.) Han Engaged the Uglies at far closer distances than multiple LS.

2.) The Uglies traveled past the falcon for some time (20x the distance of their closest approach, as was stated) before turning and firing.

3.) Even if we assume it WAS 3 LS (this is debatable, it could have been much closer) there was only a SMALL chance of hitting at that range (not impossible as Han said, but not accurate compared to close range.) This is at MOST at 3 LS. TLs (EGW&T) generally have 2-3x the range of Lasers, which means at MOST TLs would have a small chance at 10 LS. Which is an UPPER limit.

This does ignore all the other problems associated with the quote (which I am well aware of, since I own the book and its sitting right here beside me.)
.form Enemy Lines II - rebel stand

"In They 'know' that once its ready to fly, we can destroy their worldship in orbit around Coruscant; we faked up a low-power demonstration of this by positioning one of our capital ships outside the Coruscant system and firing off a laser battery attack at the worldship to coincide with the firing of our fake weapon array." - out side the system.. not Light second but maybe light hours
1 - This does not prove they can hit a moving capital ship.

2. - mention was made of spotters

3 - A Worldship in orbit around a planet makes a fairly predictable target.

In short, this is NOT valid proof of ship to ship ranges. It only sets a potential upper limit on TL ranges.
as for optical lag time.. light is constantily being reflected off a target, so unless the ship Hyperjump into a system, you will be constantily getting visual data.
Light from where? How strong is it? Are tehre any other emissions in system? Do the shields absorb them?

While we're at it, you should also add engine emissions, possible shield emissions (if its radiating energy), Jamming (its an emission) communications and sensor pulses (active sensing). Yet this does nto guarantee that you will SEE a ship. Masking technology and energy baffling tech exists. And these emissions are limited by speed-of-light in most cases (save FTL), so there is going to be significant lag time if you use this as targeting data.
Knowing the distant of a target, it tell you how old the data is, taking the speed and bearing of a ship , you can computer where the ship should be now. and where it will be if you fire...The limiting factor is computing power and how many course changes a target make..
at at 10 Light seconds your data is ten seconds old. You learn about any manuvers the ship made 10 seconds after it makes them. Just how accurate is a predictor to be able to pinpoint a ship's position ten seconds
into the future? Especially with the mobility options open to said ship.

Just had a thought...

In all the movies, which are considered canon, there appears to be only one instance in which a HTL bolt could possibly have been seen (Battle of Endor) and even in that one scene, we only see an exchange of a single green bolt from an ISD's port midship batteries, and a single crimson bolt from a ship off screen.

Considering the vast amount of batteries on a typical ISD or MonCal, why would they appear to be only firing single shots as opposed to full battery volleys? Granted, the ISD may have been crippled to almost uselessness, but I dont believe the rebel ship attacking it was that hampered.

I really do wonder what an ISD would look like in full battle. The books depict their method of engaging an enemy as a saturation attack, blanketing their target in weapons fire. C'mon GL, give us an idea how these monoliths would work in their primary roles. Even a fan-made cgi movie based on the stats that C.Saxton gives us would be impressive.

Also, it doesnt appear that TL's bolts move at C. In fact they appear to be considerably slower than that. Hence the possiblity that Capship warfare maybe conducted in a similar fashion to WW2 battles. I agree that the amount of jamming would render most automatic targetting useless, so saturation or bracketting would seem to be the most effective method of combat. Particularly as the bolts appear to be less than C, at the ranges these ships would engage, I believe that a targetted vessel may ( depending what range of course) be able to detect weapons fire from an opposing vessel ( power spike before firing?) and in the few seconds it takes for the bolts to reach their target, be able to manuver themselves to lessen the blow.

Only a portion of the TL bolt travels at C. It is this portion that does a considerable amount of damage, but is invisible. The bolt itself travels more slowly than C, but it does not do the damage.

Detect A TL bolt

Post by omegaLancer »

For some reason poeple think that they can detect an object going at SOL before it strike.. The fact is the information that you need ( whether it visible, radio or infrared) is also traveling at the same speed and would arrive at the same time or afterwards.

The Vong use plasma weapon that travel slower than C.. So there is an interval between the light it generate and the actually bolt...

In the case of a TL the visible potion is slower than C but the rest of the bolt is traveling at C.. So when you see the bolt it already to late.. Any other bolt that are spotted means that they would not have struck in the first place...

In comparsion to the speed of the actual bolt a 3000G is very slow, using the scaling of the Bismarck in comparison to it Shell velocity it has the ablitily to obtain 2% of the projectile velocity at a rate equal to 5000G...
The same or better than ISD...

and the fact that long range is more of a softing up process.. Capital ship still will need to close for the killing blow, but any hit before that will drain the shield peak defensive value..

SW has FTL sensors, as demonstrated by the ease of the Rebel detection of the Imperial fleet at Hoth. It is possible but highly unlikely that they would be able to detect weapons fire before it hit them.

I firmly believe that at the Battle of Endor the Imp fleet was ordered to hold back against the Rebels so the Emperor could use the DS to eliminate Rebels ships and infuriate Luke and turn him towards the Dark Side. When the Rebels closed to point blank range and attacked the Imp fleet they were unsure what to do, the Emperor did not order them to attack in full because the Emperor was playing with Luke and Vader at the time.

Im not sure if I buy into that theory totally. Granted the Emperor commanded the fleet to hold back and allow the Death star to do its thing, but to think that the Imperial fleet would not know how to combat a group of warships at point-blank ranger seems odd.

I dont think it would have been the first time a Imp commander had been confronted by this situation. The only viable explanation I can think is the theory that the Emperor had exerted influence over the Fleet, basically crippling the ship commanders from making any independant descisions. That would kind of explain the sparse HTL fire going on, maybe some of the captains managed to get back some control of their faculties enough to return fire rather than being sitting ducks. But by that time it would have been too late

If thats the case, I would have hated to be a crewman on those ships, watching as rebel HTL fire started to turn your ship to slag, and you were disallowed from returning fire...

Sounds like the Emperor playing games, basically reducing the Imp Fleet to a mere pawn in his little chess game between luke and vader. If the fleet was allowed to act as it should have, the battle would have turned out very very differently.

Analog firing computer and predicting future course

Post by omegaLancer »

It seem that predicting the future location of a ship is not a hard thing to due if one have a good computer, the fact that before electronic computer were used a gear driven computer was used:

Check out :http://web.mit.edu/STS.035/www/PDFs/Newell.pdf..

all the same problem were face by surface gunners and was overcome to allow the max range of their weapon to be used.. If WWI and II capital ship could handle lag time of 10 to 30 sec , using hand crank computer, plotting boards and optical director.. Using SW equivalent ( CCD, Firing computer, etc) equivalent range could be handle..

Part of the problem, though, is that it is MUCH more difficult to target an object's future location if that object can maneuver in three dimensions. Even with radar-assisted weapons, American airmen in Korea and Vietnam had to expend hundreds of rounds of ammunition for each kill they earned against enemy aircraft, and in those battles the time lag was mere seconds, and in some cases not even that.

With modern battleships, they must merely predict an enemy's position on an essentially two dimensional grid. And usually those ships have limited abilities to maneuver, and are restricted to moving more or less forward or backward even while making turns.

What does this have to do with my point? I'm talking about scanning objects in realspace via active FTL scanning (subspace scanners and tachyon scanners, which may be the sensor equivalent to hyperwave communications.)

Detecting an object in hyperspace is not the same thing as scanning FTL an object in realspace FROM realspace, and I already made allowances for this in my post.

Star by Star, page 379:

"Han risked a subspace imaging scan and located the real field of asteroids where he had expected, just inside the dust ring down on the protostar's plane of spin."

If Han is able to use FTL Scanners (Subspace IS FTL in SW after all) to locate relatively inert objects like asteroids, it should not have difficulties scanning/locating other objects, TLS included. The same is pretty much similar for tachyon scanners (which are used by FIGHTERS to track targets in combat at long range..) You don't really need to track the bolt, just detect the weapons discharges, which you could if you were scanning the ship.

Also:

"Of course, sensor systems are essential for waging war, as they allowlarge military fleets to maintain cohesive formations. In battle they are used to detect and identify enemy vessels and determine the status of weapons and shield systems."

EGW&T page 114.


"A Txs-431 cnsole normally can access a wide range of sensors - suich as electro-photo and dedicated energy receptors and full-spectrum transceivers - to identify incoming vessels and scan for evidence of damage or charged shields and weapons and to determine ho wmany life-forms are aboard."

sort of. Because the visible bolt is a "ripple" along the invisible beam, all parts of the beam, including the part where the spontaneous emission of visible light occurs (the "pulse") are damaging :) The visible part may be harmless, but its still overlaid by a nondamaging part as well.

maybe Im being dense, but if the bolts damaging invisble part (?) travels at C or close to, then that would mean that SW ships are also moving even at sub-light at similar speeds....

But that would also mean that there would be hardly any lagtime between the shot fired and impact...any evidence of this in canon? Just curious, because the movies show the bolts flying along, but until the colored part of the bolt strikes, there seems to be nothing happening.

Silly me for assuming that a speed of light beam crossing 14-20 light seconds would have a lag time between firing and impact. Silly me for also assuming they have FTL sensors.
The fact is the information that you need ( whether it visible, radio or infrared) is also traveling at the same speed and would arrive at the same time or afterwards.
Not if you have FTL sensors and can detect the discharge.

Besides which, even if I'm wrong about tracking bolts, (whcih I've provided enough evidence for to not neccesarily be so) - you're ignoring the fact that seeing the bolts isn't neccesary to dodge/evade fire. How smart does one have to be to figure out that one's opponent will fire at them, to figure out how long the bolts are delayed for, and how long one has to dodge?
The Vong use plasma weapon that travel slower than C.. So there is an interval between the light it generate and the actually bolt...


Actually, there's also the heat aspect, which is probably going to be more radiative than the light (since it will be cooling)
In the case of a TL the visible potion is slower than C but the rest of the bolt is traveling at C.. So when you see the bolt it already to late.. Any other bolt that are spotted means that they would not have struck in the first place...
Again, FTL sensors.
In comparsion to the speed of the actual bolt a 3000G is very slow, using the scaling of the Bismarck in comparison to it Shell velocity it has the ablitily to obtain 2% of the projectile velocity at a rate equal to 5000G...
The same or better than ISD...
The ship doesn't need to be that fast to dodge, especially at multiple-LS ranges. The Bolt can only move in one direction.. a ship can handle more than one easily (Even if it built up inertia, it can make SOME measure of change in its path). Your silly "shell ratios" are meaningless with the distances, accelerations, and ships involved and rely entirely on targeting computers having near-prescient preditcitve capabilities, which is far more generous than is likely to be true.

When a ship has 20 seconds of manuvering time between firing and bolt impact (whether they're dodging at random or if they can detect/anticipate), you're talking about a huge volume of space that has to be covered, prediction or no.
and the fact that long range is more of a softing up process.. Capital ship still will need to close for the killing blow, but any hit before that will drain the shield peak defensive value..
Oh yes. Those single 200 gT TL impacts will REALLY soften up an Imperator's shields... I'm sure they have no real need for concentrated fire now, do they?

But Star destroyer can fight 100 of shot

Post by omegaLancer »

Yes hundred of shots might be needed, but let look at a ISDII, it has 64 HTL alone.. with a fire rate measured in the seconds... combine with 100's of other TL batteries we are talking about fire rates of thousand of bolts a minutes... The time it take a capital ship to travel 10 light second would allow several thousand shots to be fire..

Even old time battle ship only managered to score 4-6% hits at their max range.. A single hit would normally inflict major damage.. In the case of SW ship 4-6% mean 40 to 60 hits for a thousand shot fired.

Since most SW vessel only allot 25% of their power output to shield, the hi peak values listed in ICS for AOTC is base on stored energy that would be available to negate the first hits.. So striking first, means that when the combat has gotten to range of a few LS the ship that has score the first hit is at an advantage..

know that the would be very difficult to target vessle at the ranges I propose, but the fact is that Weapon who capable of inflicting damage over the great distant that we saw in rebel stand, it would scream for miltary planner to find way to access this.. This is what promote the advantage of naval gunnary..

Rifle cannons were first used at range of less than 100 yards ( let than that at time), but navies around world quickly develop the means to use these weapon to the max...

READ what Ossus said. Thats my ENTIRE point exactly. You seem to be relying on the notion that any capital ship an ISD is going to fire upon is:

a.) NOT going to be very agile or move very much in combat, or that the captains will be totally unable to perform evasive manuvers.

b.) that the targeting computers will have tremendously accurate predictive abilities against said vessels, even iwth a lag of tens of seconds, regardless of what the other ship does.

The first one is just plain ridiculous. In a single second, a mile long ISD can cover a distance equal to ten times its own ship length, minimum, in any direction. a 30 kilometer radius. If it takes a TL bolt ten seconds to cross this distance, it could cross over 1600 km via constant acceleration, or it could accelerate for one second and glide along at 30 km/s for all ten seconds (300 km.) The potential volume that must be targeted is easily millions, if not billions, of cubic meters of space, and depending on how it manuvers, it could be ANYWHERE in that volume.


B.) is even more ridiculous. Do they give FORCE precognition to targeting computers now? As I recall, humans were considered inherently superior to machines (remember the whole reason behind the clone army in AOTC?) This is why the human eyeball is considered the best sensor system for its range (it cannot be jammed.), this is why manual gunnery is still an option. All else being equal (as technology can and often is between two SW competitors) the human factor is often the deciding factor in the SW universe.

No targeting computer is going to be able to effectively track/predict and hit even a SW capital ship at ten LS or more, unless it is immobile or can be predictably tracked without signfiicant changes in its movement. Hiding behind the mythical abilities of a so called "predictive" computer is not going to magically alter this fact.

IT doesn't matter. Each shot has to cross that same distance, and is subject to that same lag time. Staggering the rate of fire is not going to change things, because they STILL have to travel that 10 light second distance, and they are going to end up there LATER than the bolts that were fired before (by several seconds at least). Being able to fire thousands of shots Per minute is not the same thing as being able to fire thousands of shots a second, the latter of which is going to be more IMMEDIATELY relevant to "covering all vectors."

In ten seconds (the time it takes for the first or pair of botls to fire bolt to fire) a MTL (Assuming the EGW&T timeframe of one per two seconds) will fire five times. Each successive bolt is two seconds behind the last one, if we assume a steady rate of fire.) This adds up, since each bolt after the first is striking two seconds later (which is two seconds for said target to be moving around.) and it STILL doesn't deal wiht the predictive problems I mentioned before with such a sheer volume.

Extending the timeframe to increase the number of shots does not simplify your problem, it complicates it (since the additional time you spend in firing your gun is also available to your opponent in evading.)
Even old time battle ship only managered to score 4-6% hits at their max range.. A single hit would normally inflict major damage.. In the case of SW ship 4-6% mean 40 to 60 hits for a thousand shot fired.
In a minute. A minute's worth of manuvering time is going to result in a FAR larger volume to cover than 10 seconds worth.
Since most SW vessel only allot 25% of their power output to shield, the hi peak values listed in ICS for AOTC is base on stored energy that would be available to negate the first hits.. So striking first, means that when the combat has gotten to range of a few LS the ship that has score the first hit is at an advantage..
You're misinterpreting the shield rating AND shield operation. That rating measures how much power the shields can radiate away at any given instant - anyhting over that is absorbed,which leads to gradual degradation of shielding capabilities. The 25% to power quote from the ISB does not neccesarily have a direct bearing on shield dissipation capabilities, since the AOTC ICS is quite clear that shields operate as absorption and reradiation devices. To do any real damage, you have to overcome BOTH the instantaneous dissipation ability of a given shield generator, as well as the heat sink that absorbs excess energy that cannot be radiated away (or, depending on your source, absorbed and converted for ships use.)

And "A few LS" is a far cry from the ranges you are proposing as "long range.", which would require DISPERSING your fire across such a wide area as to negate effective concentration of fire that would otherwise be achievable at closer ranges. This isn't even factoring in the fact that energy weapons are LOSING energy as they travel, which means the farther they travel, the weaker the bolts get.
know that the would be very difficult to target vessle at the ranges I propose, but the fact is that Weapon who capable of inflicting damage over the great distant that we saw in rebel stand, it would scream for miltary planner to find way to access this.. This is what promote the advantage of naval gunnary..
Only if it can be done so effectively. The means at which this could be done so MIGHT be possible, but the engagements would be exceedingly rare. It is simply not effective to expect energy weapon duels to occur across such tremendous distances unless, as I have stated before, the ships involved are not moving at all, or trhey are moving in such a predictable way that they cannot easily dodge. THe majority of conflicts in SW argue against this.
Rifle cannons were first used at range of less than 100 yards ( let than that at time), but navies around world quickly develop the means to use these weapon to the max...
Irreelvant. There are limits to which you can reasonably expect to hit and effectively damage a target at long range, due to the factors I have been REPEATEDLY mentioning. The fact that they MIGHT be able to target ships at AU distances does not instantly translate into EFFECTIVE combat ranges, nor does it mean that such ranges are typical, desirable, or useful. As the REbel STand quote indicates, such long ranges are used ONLY against stationary targets. Mobile targets (which most capital ships are) are something else entirely.

. The wonder of Computer..

The old Hand crank computer used by WWII ship took into account not only speed of the target, wind speed, and other factor. And it was a Gear Driven device..

Droid in star wars are alway belittle, but yet they perform highily skill task. Probe droid, medical droids, Astrodroid ( can even store several jump info), and protocol droid.. C3peeO is capable of 6 millions form of Communication!!!!

So it not to outragous to think that a targeting computer would not be able to analyse visual data to come up with a statitical alogrithim base on observe speed bearing and manuevering behaviour, that would give the most likily future position of a vessel...

modem computer already do this in arial gun battle.. The Hud display that used to target a jet gun alert the pilot when to fire his guns when dogfighting.. The ship targeting computer take into account things like airspeed and distant..

Just look at computer simulation of weather and other complex behaviour

With SW computer/ droids, We are talking about a level of Computer technology at least 2000 years more advance than a today computers.

Stardestroyer and capital ships are not fighters and all visual indication from the film their manuevering range seem limited.

There was no evading the DS2 Super laser, or even Ion gun at Hoth...

The the original ICS show a targeting computer for the turbolaser, Tie fighters , and the Millenium falcon uses targeting computers ( you can see this in the film also).. even the Turbolaser batteries on the deathstar.

look at this:

ANH novelization p.192

"Lord Vader, we count at least thirty of them, of two types. They are so small and quick the fixed guns cannot follow them accurately. They continuously evade the predictors

The Essential Guide to Weapons and Technology / Turbolasers
Pg. 88 : Banks of turbolasers, coordinated through computerized fire-control systems, deliver sustained volleys of energy.

Turbolasers utilize computerized fire control systems to target capital ships across vast distances in deep space


you also discount that a single boardside consids or 100 of guns so that at least 4 hit every 2 seconds ( after the intial lag time)..


And the Value of shield in the ICS said Peaked.. not sustained.. From the EU there is constant reference to shield levels and gradual loss of shield after multiple hits over an interval of time. So Peak value is not a sustain value..

And how does this prove that computers would EASILY handle the task of firing at a warship moving at thousands of gees in any of three dimensions across multiple light seconds? You're assuming that because something in the past COULD do so without much trouble, that the technology would be able to duplicate the feat in the future, no matter HOW difficult the factors. Beyond which you've been repeatedly ignoring the differences I continually cite (and which Ossus has supported.)

Yet they are not nearly as creative, flexible, or independent as humans. It was proven in the Geonosis battle that the human troops were still superior to the Droid armies. Are you seriously arguing that a computer could be created as to predict what a human could acccurately do (bringing us back to your notion of magically prescient computers.)
So it not to outragous to think that a targeting computer would not be able to analyse visual data to come up with a statitical alogrithim base on observe speed bearing and manuevering behaviour, that would give the most likily future position of a vessel...


Its remotely possible, but its nowhere near as effective. Simply being "possible" is not good enough. We're talking about the DEGREE of difficulty of doing so, which is far greater than you are giving them credit for at the distances you claim.
modem computer already do this in arial gun battle.. The Hud display that used to target a jet gun alert the pilot when to fire his guns when dogfighting.. The ship targeting computer take into account things like airspeed and distant..
This does not translate automatically into the ability to accurately predict (or with even moderate or small accuracy) the path of a target at ten or more light seconds to guarantee a hit. The two are not even remotely comparable. Atmospheric combat is not the same as combat in a vaccuum, across the kinds of distances and with the kinds of acceleration you are talking about. You yet again assume the capabilities of the computer/targeting system will scale up at a rate sufficient to overcome the difficulties presented.

Also, I might point out what Ossus said about "hundreds of shots" per kill in Korea and such, and with lag time of a few seconds or less.

Just look at computer simulation of weather and other complex behaviour
Irrelevant. Predicting weather is not neccesarily the same as predicting where a ship will be at over 20 light seconds distance. Even if it is, how accurate is the prediction, and what does such accuracy require (what factors does it use to determine such, etc.) You're assuming that the comparison is valid without comparing the elements of each.
With SW computer/ droids, We are talking about a level of Computer technology at least 2000 years more advance than a today computers.


Technology DOES reach limits. You assume that there will be no limits, or that whatever advances they do make will be sufficient to overcome any problems of lag time, unpredictability of the human pilots/navigators, the acceleration, etc.
Stardestroyer and capital ships are not fighters and all visual indication from the film their manuevering range seem limited.


Because visual ranges are much shorter than interstellar ones, and human reaction times may require slower accelerations/speeds? And if we're to follow this logic, I could just as well point out that "all visual evidence points to ranges FAR below a light second.. thousands or hundreds of kilometers."

And even THEN, even if acceleration is slow, the observed accelerations in the movie are enough to render all your range claims irrelevant.
There was no evading the DS2 Super laser, or even Ion gun at Hoth...


This gives us about 3 examples to draw on. In two fo them (first ion cannon shot and the first TL firing) they weren't even EXPECTING it. In the other superlaser blast, the ranges were NOT many light seconds away, but thousands of km or so, with reaction times at best a few seconds (in a close-quarters battle, I might add, being hemmed in by the Imperial fleet)

So at BEST, you're saying they can't dodge weapons fire at a few thousand km to a few tens of thousands of km. This isn't even REMOTELY close to saying they can't dodge at tens of light seconds.
The the original ICS show a targeting computer for the turbolaser, Tie fighters , and the Millenium falcon uses targeting computers ( you can see this in the film also).. even the Turbolaser batteries on the deathstar.
Which tells us nothing of the quality of some computers (which can be either exceptional, or so bad that exceptional skill on the part of the gunner is required to ensure any hits.) Besides which, the existence of targeting computers does not automatically translate into the ability to hit targets at tens of light seconds, so it does nothign to support you.
look at this:

ANH novelization p.192

"Lord Vader, we count at least thirty of them, of two types. They are so small and quick the fixed guns cannot follow them accurately. They continuously evade the predictors


This helps you how? for one thing the distances are even shorter than at Endor or Hoth (with the Superlaser or ion cannon), and they couldn't even target FIGHTERs you were claiming were barely manuvering well. All this tells us is that your so called "predictors" cannot accurately predict the paths of barely-manuvering targets at point blank range (this of course ignores the jamming aspect... or that the guns were designed for bigger ships.)

In any case, this does NOT prove your claimed ability to target ships at 10s of light seconds. If anything, you've hurt your position even more.

The Essential Guide to Weapons and Technology / Turbolasers
Pg. 88 : Banks of turbolasers, coordinated through computerized fire-control systems, deliver sustained volleys of energy.

Turbolasers utilize computerized fire control systems to target capital ships across vast distances in deep space


So? According to BTM, ISD TLS use targeting computers that assist them in targeting small starfighters. All this tells us is that they use computerized fire control with the guns. It does not specify distances, nor does it say anything about being able to accurately hit targets at many light second, much less the ranges you are claiming. "vast distances" is not a specific enough reference to give us a clear idea of the ranges involved.
you also discount that a single boardside consids or 100 of guns so that at least 4 hit every 2 seconds ( after the intial lag time)..
No, I don't. But the volume of fire an ISD can generate, while tremendous, is not sufficient to cover all vectors adequately at teh ranges you suggest. And even if it is, it requires such a dispersion of fire that damage is unlikely to be very effective unless you get a lucky HTL shot, and possibly not even then. Individual, or even a handful of MTL shots are not going to neccesarily do much against another cruiser or Star Destroyer.
And the Value of shield in the ICS said Peaked.. not sustained.. From the EU there is constant reference to shield levels and gradual loss of shield after multiple hits over an interval of time. So Peak value is not a sustain value..
I suggest you look up teh definition of "peak" on britannica or encarta. "sustained" has nothing to do with it neccesarily, it can refer to "maximum" values. In this case, the shield ratings in the ICS refer to the maximum power levels that the shields can dissipate. I might add this is based on what Saxton himself told me, in clarifying those figures for the ICS. If you're so inclined to disagree with his explanation, take it up with him.

Actually, predicting the possible flight path is very easy even today when given the acceleration characteristics of the target.

The problem is getting the senser data in real life combat,but that is not that much of a problem as it can be refined over time using statistical methods.

Anyway, time to do some math.

Engragement a 1c distance.

Find hit ratio at 1c for a ISD

Find area of isd with respect to the gun.
say 1km^2 This differs with orientation of ISD to the gun.

Find acceleration...3000g = 30000m/s^2

Find the area in which the ISD could be in one second.

change in Distance travelled
d = at^2/2 = 30000m = 30km.

Assume that the angle in which the ISD can accelerate is around 45 degrees. This differs with orientation as well.
since the beam intersects the ship's path as opposed to detonating at preset distance, depth can be ignored

a = pi*r^2 = 706km^2

Hit rate = 1km^2 / 706km^2
0.0014 or 0.14% hit rate.

That's a pretty lousy hit rate at that range. It may even be more expedient to save that energy to wait for the enemy to get closer, especially since one shot will not significantly impair a larger ship's ability to fight, and since it may not be worth firing that much to destroy smaller ships outright.
