Via a laser-powered solar sail that took decades to accelerate to that speed.
I don't recall the exact speed but a human warship had no trouble accelerating up to an appropriate speed to 'catch' it within a few days (at the most).
I'm pretty sure it slowed down when it began to approach the Murcheson's Eye. Checking the book, it was going .07 c when it arrived in the solar system. Can't find the speed it was going in the middle space, but it was presumably faster. I mean, the Empire uses the Langston Field to enhance their ships power production and speed, but I don't think it well enough to match a ship being fired by laser cannons.

Federation ground troops are regularly defeated by just about everyone - stormtroopers, modern military, even the monstrously incompetent Jem'hadar, Klingons and Ferengi. So Motie warriors would be overkill. But this is irrelevant, because the Federation could glass the Motie homeworld at will. The only way they're going to be a problem is if the Federation stands by for a couple of centures while they expand and bring their tech base up to Trek standards.
The Moties themselves have repeatedly tried to destroy their foes (other Moties) countless times by raining down pure nuclear destruction (so much so that their planet no longer has uranium and their seas are all shaped like craters), and that hasn't seemed to stop their race from surviving, or retaining it's technological advancement. Besides, does the Federation even use such salt-the-earth tactics against intelligent races?

I'm pretty sure a megaton level laser (what you'd need to penetrate a Fed ship's shield) would not be feasible without technobabble. With a 1 megaton yield and 90% efficiency you end up with the thing pumping the equivalent of a 100 kiloton bomb's worth of energy in waste heat into its own assembly with each shot.

There's also the matter of manueverability. It's nice that you can do .92 c but it doesn't mean anything when the soft SF ship pulls away at a 90 degree angle from your path, at 10 times your highest acceleration. Congradulations, you're now moving at .92 c at a 90 degree angle from your target, and since his acceleration is ten times yours there is absolutely nothing you can do about it!

They can attack the nodes, of course, but any interesting arrangement of them (ie, providing a percentage of the sun's power) is going to involve so many mirrors, lenses, collectors and whatnot that no typical Trek power has enough ships to make a significant impact, short of destroying the star.
This is like saying that you can't disrupt a modern power distribution network because there are so many transformers and wires. You don't need a number of ships equal to the number of targets; such enormously complex systems are generally quite metastable, and do not tolerate significant damage well.
Nonsense. First, they need to know where the attacks are coming from. How are they going to know that, when it stretches optical resolution simply to determine that a star system has planets?
This is probably the most difficult of the assumptions, granted.
It's not just "difficult"; it's nonsense.
Second, it would take time to build a huge lens, and the Federation can easily disrupt construction whenever it pleases.
Alternatively, the standard collectors can just be pointed towards the target star system. Diffusion would be rather large but enough to boil oceans.
Oh sure, a civilization entirely dependent upon this vast solar power network (probably constructed over a period of thousands of years) will just temporarily deprive itself of power in order to modify their entire power collection network so that it can convert its energy into lasers and fire it at a distant star system in the hopes that an enemy might be there. Yeah, that makes sense. And in the meantime, the Trek civilization would just ... watch them do this?
Well, my point with that (barring system-destroying antics occasionally displayed) is the raw patheticness of industry in Star Trek. Several thousand ships is a major fleet, sponsored by the industry of over a hundred worlds. A Hard Sci-fi civilization that is harnessing a significant power of its parent star isn't going to be significantly hurt by the loss of a quadrillion elements. If each Trek ship is destroying a thousand a second, it's going to take decades for Trek to 'win'.
Trek has decades to win. It has millennia, in fact. What do you not understand about the difficulties of overcoming such an enormous propulsion gap?
It's not so much that Trek is just sitting there and taking it, it's that the scale of industry on the part of the HSF civilization is so far beyond them that they can't really stop the HSF civilization from directing energy, any more than the HSF civilization can outmaneuver them.
The fact that a civilization is very large does not mean that it can indefinitely withstand attacks that it cannot defend against. You are still basing your argument upon an assumption of Trek passivity. Highly technological infrastructures are more easily disrupted, not less.
This is defeated by the various plot devices of course (the 'blow up the Sun' rocket they have...) but the Federation doesn't support such tactics.
If this half-assed scheme of yours worked and they exterminated the population of Earth, the Federation would quickly learn to support such tactics. This civilization could be exterminated completely, and unlike the Federation, it doesn't have a far-flung interstellar network to perpetuate its species.
And the last part is just a reflection of my point - any vaguely competent civilization is going to have an industry on such a scale that it will take decades for the UFP to deal with short of using a superweapon.
It HAS all the time it could possibly need. Why do you not grasp this?
If it really came down to war between the UFP (or any of the major Trek powers) and the STL Xeriar Solar Empire, wherever it is, one viable strategy would be to manufacture warp missiles similar to the Cardassian device seen in the V'ger episode "Dreadnought" —essentially a 100 metre automated shuttlecraft loaded with 2000kg of matter/antimatter in the warhead (although it wouldn't need anywhere near that much material in the warheads to destroy orbital habitats and power stations) and capable of warp 9 speeds. These could be mass-produced (at least on a far quicker schedule than starships) and fired in barrages at the target star system and there would be no way for the enemy to defend itself or retaliate in sufficient time before their civilisation would be destroyed.
When ballots have fairly and constitutionally decided, there can be no successful appeal back to bullets.

They have an agreement not to glass the rural areas or those huge museums / teaching centres they have scattered all over their planet, which they all seem to stick to. That's hardly 'glassing the planet'.

Yes, Sisko did in 'For The Uniform', had they not done the 'swap the populations' trick everyone on those two planets would have died. Plus if the Federation left the Moties alone but the Romulans or Cardassians get wind of how dangerous they are, they'll be over to glass that place just like they glassed (what they thought was) the Founder homeworld.

Not just population. Incumbent with having a population that size is the infrastructure to support them, and the energy to power it. Particularly since this civilization can also launch starships – that implies a certain level of energy available to them in order for it to be economical. This civilization will be able to call upon more energy and resources then the entire Federation is able to. It’s the point that has been raised with the debate against Star Wars before – even if we went with the sheer stupidity of people like RSA the sheer scale of the industry means that they can bury the Federation, even if only by building things faster then the Federation can destroy them.

Lasers and particle beams are limited by structure. You can't just make arbitrarily powerful lasers if you stick with hard sci-fi, because of the need to reflect the beam.
Cooling the reflector isn't a big deal - I could use a phased array, which makes the cooling problem easier by reducing the heat load at a given point. Or stick an Excalibur type warhead on a drone. I don't need much power – Battle Lines and Survivors both had 40 MW phasers and “anti-proton beam”s as threats. Who Watches the Watchers had 4.2 GW be enough for a phaser bank, and even on the high end Survivors had a 400 GW beam kick the ass of a battleship. The first 3 examples are all well within the range of solar power stations that were designed in the 70's

You could theoretically make enormous particle beam weapons, but they would be massive and correspondingly difficult to accurately aim or swiftly re-orient.
Like I said, I don't need much. Hell, a 2.1 MJ disruptor was enough to shake the E-D in Conundrum. Though combining a charged particle beam with a magnetic sail to get a better starwisp may be a more efficient use.

Drones would have to operate off limited fuel supplies and defend orbital installations which are essentially defenseless against long-range attack.
Why must the drones have limited delta V? I could just as easily use beamed power propulsion. I can cut that by making them variations on the starwisp, or replace the mass of the engine with more fuel send the energy remotely. And even if I make them carry all their fuel, so what? They get the bonus from the relative motion of their launch platform. FTL is not as big an advantage here – firstly the Picard Maneuver in its brilliance of “get close to the guy and shoot him” is regarded as something rare, wonderful, and incredibly clever, not a standard tactic. Secondly, even if they do that, at any reasonable clip the starship will be out of range for the Trek ship before they get their shot off. The Federation may see no need to not use FTL to pick the time and place of the engagement, but by the same token the hard sci-fi group has no reason to come to a dead stop relative to the Federation ship, line up, and fire like some kind of Napoleon era army in a vacuum.

As for the idea that the space infrastructure would be defenseless, I very strongly disagree with that idea.

Earth's orbit is 1 AU. Mars' orbit is ~1.5 AU. At 300 km/s, it would take three days for a projectile to reach Mars' orbit. Meanwhile, your average soft sci-fi ship makes that trip in minutes, and it's a full-functioning ship, not a missile. If we ignore the fact that it's not really possible and just look at tactical balance, soft sci-fi kicks the shit out of hard sci-fi. Accept it.

PS. You can't be serious about simply "aiming" a 50,000km long payload accelerator at a moving target with attitude control jets.
I was thinking more about using it against a ship supporting troops. Voyager is capable of landing on the surface, so I always figured it could do double duty as a troop transport. A ship in a stationary orbit is a sitting duck, and the loss of it will hurt the invading troops severely in terms of fire support, coordination, logistics, and moral (“Well, there goes our ride home guys”). The projectiles lack any kind of subspace tech or presence, so the Federation is going to have a really fucking hard time seeing it coming.

Your objections to the Valkryie's use as a warship are irrelevant. I cited that as a counter to your statement that “.92c” and “hard Sci-fi” do not belong in the same post, not holding it as an example of the good warship. The First Law of Thermodynamics in no way forbids lighthuggers like you claimed. Solar energy is more then enough to launch vast numbers of relativistic starships, no matter how it is packaged for the trip. If nothing else, I could build a 300 AU long accelerator and throw the starships up to relativistic speeds, using magnetic sails to slow at their destination. Only our lack of imagination is the limiting factor. It is an engineering problem, not a physical one.

Even drag from the cosmic microwave background is insignificant. Even at a gamma of 100, the pressure of the blueshifted microwave photons is only about 1 micronewton per square meter. While it could conceivably establish a maximum possible velocity, I'd be hard pressed to think of a scenario when you would need to get that close to c.

Only two things could preclude a lighthugger: One is the interstellar space medium (ISM), and that doesn't appear likely. We don't know enough about dark matter to know how it would interact, though assuming it is just poorly lit normal matter would be the most conservative route. At the very least it is premature to say that the ISM make relativistic space travel impossible. Particularly since simply streamlining the craft will do much to help, not to mention the possibilities of magnetically shunting the ions aside or shooting down dust. The other is the Second Law of Thermodynamics. Time dilation on the starship should effect the effectiveness of the radiators, though how much I'm not sure. This may only limit the acceleration the ship can pull.

I think one of the problems here is that we have not defined the opposition. Stating that they must be a “Had Sci-fi” group is incredibly broad – as was pointed out, that ranges from something like Charles Stross' Halting States, where the setting is a mere ten years from now, there is no space presence, and the highest technology mentioned in it are quantum computers that cost a few million British pounds; to something like Alistar Reynold's Revelation Space saga, where humanity has carved out a volume of space 10,000 LY in diameter and inhabits everything in there, with lighthuggers, Dyson swarms, atomic level computers, and molecular technology. And that makes all the difference – if we drop Luna from The Moon Is A Harsh Mistress in where the Moon is, obviously Manny, Mike, and the Professor are going to have a rough time of it. But if we were to replace the Klingon Empire with the group from Ken McLeod's Long Gun story then the Federation will be annihilated before their ships can even make it halfway across it. Without defining what the opposition has this is going to be a lot trickier to debate. That said, I see several main issues that I believe make this a win for the Hard group:

• Computer technology. It is routinely noted that our present computer security and programming is superior to Trek technology. Given current trends in computing and this information I think it is a reasonable conclusion that an advanced hard sci-fi civilization will have them beat in this area. And that they will exploit it. From the prefix code in The Wrath of Kahn to the destruction of the Yamato to the times that Holodeck simulations threatened the ship we know that access to the main computer is a major threat. I have more trouble believing that any future society won't run roughshod over the Federation via their own computers then the opposite.
• Time. The point has been brought up that it will take millennia for anything launched from the hard group to reach the Federation. This is obviously true if the opposition replaced the Klingons or Romulans. Yet as the placement has never been defined, this cannot be assumed to be true. If the moons were swapped like I proposed above, then the Federation is going to have Mike dropping dumpsters on their heads long before they can recall a ship to Earth to try and dig the Loonies out. But what we do know is that Trek will take a considerable amount of time to go after the opposition. Consider: even with the incredible speed of Warp drive, it would still take years to bring ships in from across the Federation. This is time that the opposition can use to prepare themselves. They are likely to be screwed for offense (though it isn't a given) but they can play defense well enough to give the Federation a thumping.
• Population. Once they do get there, what is the Federation going to do? I'm hard pressed to think of a hard sci-fi series that has a significant space presence and doesn't have more people in a single system then the Federation has in 10 systems. Most of them have single systems that outnumber the entire Federation by orders of magnitude. How will they subdue them, threaten to commit genocide on an entity larger then their entire civilization? I rather doubt threatening to shoot down space installations will be effective. One can reasonably expect humans will keep fighting wars in the future and good fences will still make good neighbors, so they would likely already have defenses installed. If not they would certainly do so as soon as they went to war. Phasers would have limited effectiveness against planet, moons, comets and asteroids due to their relatively low power, and space stations would have to defend against weapons of similar levels already. As for torpedoes, first I would expect that they would already mount extensive point defense in space and missile defense for planets. And even if they can fire at them, it won't be very effective against the largest population centers. Wow, you bombed the fuck out of the lunar colony. Too bad it is built completely underground to take advantage of shielding. You didn't do a damn thing. The end result of this means that the Federation will have to bring in ground troops and go door by door fighting across a star system. That is not a winnable situation, particularly when you think about the time and travel bottleneck. How are they going to hold what they take?
• Sensors. One recurring theme with Star Trek is that the target is using subspace technology, and that is what lets their own subspace sensors spot them. But the opposition doesn't use any subspace. So Trek would be damn near blind, at least until the recalibrate the positronic flux suppressor by 1.21 jiggawatts and discover the telescope. This is a major advantage. It is very hard to fly to a battle and fight when you can't see where it is or what is shooting at you. This is closely tied in with the population point – given that one can expect structures in the Oort cloud, the Federation has to find them. Find them and eliminate them before they can spawn daughter colonies.
• Economy. A civilization with sufficient space infrastructure to routinely launch starships and support the expected population it would have by that time has more economic muscle then we have seen from the Federation. It is the same as Coruscant shows that Star Wars could buy and sell the Federation several times over. Tied in with that, what is stopping the opposition from expanding as fast as they can during the war? Even if they are stuck within the star system, their combined industrial output means they should be able to produce more stations. In fact, I would not be surprised if a mature space civilization could spawn more daughter colonies faster then the Federation could conquer them.
• Culture. More people and better computers and interconnectivity means more interactions means more expressions of these interactions and viewpoints, which, after a suitable amount of time has passed since the creator of said expression or viewpoint has died, is known as art. Look at Web 2.0 and the way Internet culture has exploded as a result. The opposition can hunker down, throw out the occasional starship to do battle, fight the invading troops, and export their culture.
• Victory conditions. The scenario makes a conventional win damn near impossible. The opposition can't plausibly take out the entire federation. Depending on where they are placed they may be able to knock earth or other important signatories around the head enough to get a victory, but that isn't a good assumption. The fact that one cannot fight an interstellar war means they can't do much for offense. By the time the took out the Utopia Planetia shipyards, the ones they had destroyed first would have been rebuilt. Against smaller hard sci-fi groups the Federation may be able to bring in enough people to win, but there aren't many groups they can do that to. Even a group as poor as the survivors in The Outcasts From Heaven's Belt have the sheer numbers to bury the Federation. And it is unlikely they would shift to mass murder without severe provocation.

It is my belief that against most of the space operas regarded as Hard sci-fi the Federation would be curb stomped. But if we define the term hard sci-fi as only those within the limits of what is know instead of the usual fuzzy definition then it becomes mush more difficult. I think in that kind of situation you would see almost a kind of stalemate – Federation worlds and staging areas nearby (within a few light years) would periodically be hit by strafing raids and infowar attacks, while Federation attacks against the target system would be a cross between Operation Overlord and Stalingrad – attacking ships would deal with infowar and defensive fire to destroy or harry them back, while the invading troops would be doing a variation on city fighting where the terrain is much more hostile due to the nature of the environment and the fact that they are so heavily outnumbered. It would be massive resource sink. But in that time the superior economic and influence power of the opposition would come into play. Just as what happened when Sparta conquered Athens, even if the Federation wins the war they lose their civilization. Their culture, economy, ideas, and way of life would be buried by the sheer volume of competing values from the opposition. The free market of ideas would come into play, and the Federation as it once was would disappear. To me, that would be a win for the opposition. They already have enough people that a change in government would be largely unnoticed, but the Dominion War shows that the same is not true for the Federation.

Ok, hit the print button, you will want this for later.

I rejected the idea of RKVs against planets out of hand, both because of the fact it is genocide, and because FTL drives mean that they can take them out. While it is not an option they have with starships due to the shielding and point defense they will mount, against expendable missiles the Federation can drop things in front of them to destroy them.

This got me thinking about if there was another way to do things. Obviously a giant laser would be completely undetectable, as it travels at c, and you can't stop it by tossing the litter box out the airlock. But how does one construct a giant laser?

Then I got to thinking about Excalibur (the hydrogen bomb pumped X-ray laser missile defense system) and how free floating accelerators just have to be at the right place at the right time rather then locked in line. If you just put a bunch of nuke pumped laser bombs in line and timed the detonation right, you would get a giant laser cannon. I looked online to find out more about this and found a couple of Usenet posts mentioning it, which I used as a base for this.

Put focused nukes covered in lasing material in space with a good set of station keeping thrusters, and point them towards the helpless planet. A trigger laser fires along the sequence, detonating them when a photosensor gets the signal. As the bombs go off they excite the lasing cylinders. The first few will lase indiscriminately in all directions, but eventually you will get a self amplifying wave that increases exponentially as it goes through the series. The basic idea behind lasing is that an atom gets put into an excited state when a photon hits it with just enough energy to hop an electron up an orbit. If this atom is left alone, then the electron will eventually hop back down on its own, emitting a photon in a random direction. If this atom is hit by another photon, this trips the electron back down, releasing two photons in the same direction as the impacting photon. So lasing acts as a light amplifier. Here the timed explosives and their sheer power are acting as a substitution for the traditional two-way multipass mirrors used in conventional lasers. After a few explosions in, the cascade effect has resulted in the lasing material being completely saturated. Every atom hit by the pulse will already be excited, so you will get the amplification of the beam with nothing left over. At that point the pulse just gets increasingly powerful and focused. Towards the end the laser beam should be a perfectly parallel pulse concentrating a large fraction of the energy of all of the bombs into a single momentary pulse.

Now there is a physical limit to the gain of your amplifier that can't be increased just by adding more amplification stages. It is based off the cross sectional area of the lasing block. For a conventional single pass laser you have a pretty long way to go before you hit that limit. Beyond it, you get a more power beam by increasing the cross sectional area. This isn't a simple single pass, but the idea still holds – to get the requisite power you would have to increase the cross sectional area by increasing the radius of the lasing material or by using multiple bomb sequences pointed at the same far off target. The former is more appealing to me, so in that case you would want them to be spaced apart exponentially instead of linearly in the rough shape of a cone. However there is probably some upper limit on the energy density a lasing material can take before it starts absorbing energy instead of continuing to boost the pulses' energy. So you will probably need multiple bombtracks anyways, but I'm not sure of that. Back to the cone - the spacing between the bombs should increase each time by the same percentage that the radius of the lasing material does (which apparently should be about the square root of the optimal gain.) This would break down at the apex of the cone because you would hit the minimum size for a bomb.

I don't know about efficiency of the lasing, but if the material resulted in an X-ray with a wavelength of 0.01 nm and the beam was 1 meter wide and the target planet was, say 32 lightyears away the beam would be spread over a circle 3,700 km in diameter when it hit. Since the Earth is about three and a half times as wide I'm fine with that. Now the length of the cone itself becomes a question. For a beam 1 m wide with a divergence of 1.2*10^-11 radians the cone will only need to be 8.2*10^10 meters long. That's 273 lightseconds, or only 0.55 of an AU. Not bad for a big honking planet killer. And it gets better – the thing scales with ridiculous ease.

Ladies and gentlemen, I present to you the final word in plausible interstellar warfare. The victim has zero warning what so ever, and even if hey did they couldn't do anything about it. Well, ok, I guess that isn't quite true. Those on the far side would see their planet cause an eclipse. Or start to see at least, because the plasmafied atmosphere would be radiating a couple trillion watts per square meter, so their optic nerves would fry before they could finish transmitting the image to their brains. Which wouldn't be working, as the resulting EMP should be strong enough to actually take out their central nervous system. Since this would sterilize the planet, they could hope to become fossils – no bacteria to make them rot, only erode from the elements or be buried. Except the hypersonic plasma shock wave will incinerate them, so there will be no remains to fossilize. I suppose some inhabitant might possibly survive if they were in some kind of Norad like bunker. But that wouldn't last very long. The energy input would boil off a good chunk of the oceans – a few feet at least. So the atmosphere would be broiling and much thicker, with a different oxygen content. Granted, it would condense and fall back, creating massive flooding, mudslides, hurricanes, etc that would wipe out any signs of civilization that may have survived for whatever reason. But in the mean time that water vapor would be a very effective greenhouse gas; warming the place faster then the industrialized society could possibly hope to do. This would cause a massive out gassing of the planet’s crust, giving the atmosphere something roughly approximating Venus. Only Venus doesn't get hit by asteroids this often – the blast would throw a lot of material into orbit, and it would come raining back down, going off like a series of nuclear bombs. So those survivors aren't going to last very long.

If I was feeling real ambitious, I'd figure out how many bombs I would need for my Death Star wannabe. I know I want the end result to be about 1 petaton, though I guess only a few teratons would work if I was ok with only doing a Yucatan style extinction event. But I'd need to figure out the efficiency and how dense each slice of the cone would be (in terms of bombs/km^3) to get that. Instead, I'm going to bask in the radioactive glory that comes with someone finally managing to out-massacre Shep.

With a 1 megaton yield and 90% efficiency you end up with the thing pumping the equivalent of a 100 kiloton bomb's worth of energy in waste heat into its own assembly with each shot.
Why the fuck would I need something anywhere near that powerful? Their entire shields may be able to tke a few MT, but the intensity is nowhere near that level. GW level weapons are a threat to them.
There's also the matter of manueverability. It's nice that you can do .92 c but it doesn't mean anything when the soft SF ship pulls away at a 90 degree angle from your path, at 10 times your highest acceleration. Congradulations, you're now moving at .92 c at a 90 degree angle from your target, and since his acceleration is ten times yours there is absolutely nothing you can do about it!

Particularly since this civilization can also launch starships – that implies a certain level of energy available to them in order for it to be economical. This civilization will be able to call upon more energy and resources then the entire Federation is able to. It’s the point that has been raised with the debate against Star Wars before – even if we went with the sheer stupidity of people like RSA the sheer scale of the industry means that they can bury the Federation, even if only by building things faster then the Federation can destroy them.
You're completely ignoring the fact that the Federation basically has unlimited time to develop a way to defeat this civilization, and the enemy has no remotely practical way of striking back.
Cooling the reflector isn't a big deal - I could use a phased array, which makes the cooling problem easier by reducing the heat load at a given point. Or stick an Excalibur type warhead on a drone. I don't need much power – Battle Lines and Survivors both had 40 MW phasers and “anti-proton beam”s as threats. Who Watches the Watchers had 4.2 GW be enough for a phaser bank, and even on the high end Survivors had a 400 GW beam kick the ass of a battleship. The first 3 examples are all well within the range of solar power stations that were designed in the 70's
That does not refute my point. Yes, it doesn't take enormous power to take out a warship. So what? How the fuck are you going to hit ships which can appear at any arbitrary place anywhere in your home system without any warning, fire, and then disappear before you can even get a single radar reflection? Have you even vaguely tried to think this out?
Like I said, I don't need much. Hell, a 2.1 MJ disruptor was enough to shake the E-D in Conundrum. Though combining a charged particle beam with a magnetic sail to get a better starwisp may be a more efficient use.
See above.
Why must the drones have limited delta V?
Ummm, the laws of physics?
I could just as easily use beamed power propulsion. I can cut that by making them variations on the starwisp, or replace the mass of the engine with more fuel send the energy remotely. And even if I make them carry all their fuel, so what? They get the bonus from the relative motion of their launch platform.
Bullshit. That launch platform can only achieve those high velocities of yours on a fixed axis, which makes its forward velocity totally useless for launching torpedoes at anything which does not conveniently sit on that axis.
FTL is not as big an advantage here – firstly the Picard Maneuver in its brilliance of “get close to the guy and shoot him” is regarded as something rare, wonderful, and incredibly clever, not a standard tactic.
It is easily done, and would become a standard tactic against any enemy which is incapable of responding to it. You're just trying to handwave away anything that you have no answer for.
Secondly, even if they do that, at any reasonable clip the starship will be out of range for the Trek ship before they get their shot off. The Federation may see no need to not use FTL to pick the time and place of the engagement, but by the same token the hard sci-fi group has no reason to come to a dead stop relative to the Federation ship, line up, and fire like some kind of Napoleon era army in a vacuum.
More bullshit. They don't need to hit the enemy's starships. They can fuck up his planets and fixed installations.
As for the idea that the space infrastructure would be defenseless, I very strongly disagree with that idea.
Too bad.
Earth's orbit is 1 AU. Mars' orbit is ~1.5 AU. At 300 km/s, it would take three days for a projectile to reach Mars' orbit. Meanwhile, your average soft sci-fi ship makes that trip in minutes, and it's a full-functioning ship, not a missile. If we ignore the fact that it's not really possible and just look at tactical balance, soft sci-fi kicks the shit out of hard sci-fi. Accept it.
No answer to this?
PS. You can't be serious about simply "aiming" a 50,000km long payload accelerator at a moving target with attitude control jets.
I was thinking more about using it against a ship supporting troops.
And that somehow makes the idea practical?
Voyager is capable of landing on the surface, so I always figured it could do double duty as a troop transport. A ship in a stationary orbit is a sitting duck, and the loss of it will hurt the invading troops severely in terms of fire support, coordination, logistics, and moral (“Well, there goes our ride home guys”).
Oh yeah, as if the Feddie starship couldn't simply change its course slightly every now and then. Just how fast do you think this 50,000km long accelerator would re-orient itself, and what kind of settling time, rise time, and positional accuracy would you seriously expect for this operation?
The projectiles lack any kind of subspace tech or presence, so the Federation is going to have a really fucking hard time seeing it coming.
So? Even if this ridiculous scheme actually works once, it is trivial to develop a countermeasure for it. As for the whole idea of landing ground troops, the Federation sucks on the ground. This is well-known. But if we're talking about a "total war" situation and one group is looking to completely defeat the other, the option of simply trashing his planets and fixed installations is available. I don't see why there would be any ground actions at all.
Your objections to the Valkryie's use as a warship are irrelevant. I cited that as a counter to your statement that “.92c” and “hard Sci-fi” do not belong in the same post, not holding it as an example of the good warship.
Fine, I bow to the overwhelming power of your nitpickery. Perhaps you could have been even more of a pedantic fucktard and pointed out that we can accelerate subatomic particles to .99c today, thus further disproving your nitpicky interpretation of my statement.
The First Law of Thermodynamics in no way forbids lighthuggers like you claimed.
We're talking about sci-fi WAR, fucktard. If you're talking about sci-fi WAR, it is not enough to say that we might hypothetically find ways to slingshot an object at near-relativistic speeds. It's no more relevant than the particle accelerator example. You need to find tactically useful ways of achieving those speeds for warships, otherwise you're just engaging in pure red-herring bullshit.
Solar energy is more then enough to launch vast numbers of relativistic starships, no matter how it is packaged for the trip.
It is enough to theoretically launch starships which would eventually reach relativistic velocities after an extremely long time, and only on a fixed axis. Thoroughly irrelevant to anything we're talking about here, and not even remotely comparable to what a typical soft sci-fi civilization can do.

Your bullshit is breathtaking; you have even taken tactics which they have used before (and quite easily so, having improvised them on the spot and then taught them at the Academy) and then declaring that they wouldn't use them here even though the enemy would have no way of responding to them. Are you so hostile to Trek that you wish to knock it down even in situations where it has a logical overwhelming advantage?
If nothing else, I could build a 300 AU long accelerator and throw the starships up to relativistic speeds, using magnetic sails to slow at their destination. Only our lack of imagination is the limiting factor. It is an engineering problem, not a physical one.
Except that you are talking about the wrong problem. What part of this do you not understand?
Even drag from the cosmic microwave background is insignificant. Even at a gamma of 100, the pressure of the blueshifted microwave photons is only about 1 micronewton per square meter. While it could conceivably establish a maximum possible velocity, I'd be hard pressed to think of a scenario when you would need to get that close to c.

Only two things could preclude a lighthugger: One is the interstellar space medium (ISM), and that doesn't appear likely. We don't know enough about dark matter to know how it would interact, though assuming it is just poorly lit normal matter would be the most conservative route. At the very least it is premature to say that the ISM make relativistic space travel impossible. Particularly since simply streamlining the craft will do much to help, not to mention the possibilities of magnetically shunting the ions aside or shooting down dust. The other is the Second Law of Thermodynamics. Time dilation on the starship should effect the effectiveness of the radiators, though how much I'm not sure. This may only limit the acceleration the ship can pull.
Thank you, Professor Google. Is there any other material which is completely irrelevant to this discussion which you can dredge up in order to bolster your perceived credibility without addressing the actual subject of discussion?
I think one of the problems here is that we have not defined the opposition. Stating that they must be a “Had Sci-fi” group is incredibly broad – as was pointed out, that ranges from something like Charles Stross' Halting States, where the setting is a mere ten years from now, there is no space presence, and the highest technology mentioned in it are quantum computers that cost a few million British pounds; to something like Alistar Reynold's Revelation Space saga, where humanity has carved out a volume of space 10,000 LY in diameter and inhabits everything in there, with lighthuggers, Dyson swarms, atomic level computers, and molecular technology. And that makes all the difference'
No, it only extends the time it would take to defeat them. The Federation can concentrate forces at any desired point in a matter of months. This civilization would take thousands of years to accomplish the same. This is the mother of all force multipliers.
Computer technology. It is routinely noted that our present computer security and programming is superior to Trek technology. Given current trends in computing and this information I think it is a reasonable conclusion that an advanced hard sci-fi civilization will have them beat in this area. And that they will exploit it. From the prefix code in The Wrath of Kahn to the destruction of the Yamato to the times that Holodeck simulations threatened the ship we know that access to the main computer is a major threat. I have more trouble believing that any future society won't run roughshod over the Federation via their own computers then the opposite.
Do you honestly not understand that the timeframes of this war are so long that the Federation could deploy virtually every Trekkie wank scenario they've ever concocted? They really could re-develop the Genesis Device, mass-deploy it, and then launch swarms of them. They really could develop trilithium nova bombs, load them into long-range warp torpedoes, and scatter-shot them through the enemy's territory. They really could deploy cloaking devices on every ship. All of this wanky bullshit which is totally ridiculous and irrelevant to a SW vs ST discussion becomes completely probable and realistic given the kind of timeframe the Federation has available to it in this scenario. Do you honestly not understand this?
Time. The point has been brought up that it will take millennia for anything launched from the hard group to reach the Federation. This is obviously true if the opposition replaced the Klingons or Romulans. Yet as the placement has never been defined, this cannot be assumed to be true. If the moons were swapped like I proposed above, then the Federation is going to have Mike dropping dumpsters on their heads long before they can recall a ship to Earth to try and dig the Loonies out. But what we do know is that Trek will take a considerable amount of time to go after the opposition. Consider: even with the incredible speed of Warp drive, it would still take years to bring ships in from across the Federation. This is time that the opposition can use to prepare themselves. They are likely to be screwed for offense (though it isn't a given) but they can play defense well enough to give the Federation a thumping.
Surely you know enough military history to know that if you can't take out the enemy's ability to wage war and he can, then you will eventually lose. Even the most spectacular tactical victories would only delay the inevitable.
Population. Once they do get there, what is the Federation going to do? I'm hard pressed to think of a hard sci-fi series that has a significant space presence and doesn't have more people in a single system then the Federation has in 10 systems. Most of them have single systems that outnumber the entire Federation by orders of magnitude. How will they subdue them, threaten to commit genocide on an entity larger then their entire civilization?
If your only argument is that the Federation would refuse to commit itself to do what is necessary to defeat this civilization despite the apparent "total war" scenario implied by the OP, fine. But if they're going balls-out, their victory is inevitable.
I rather doubt threatening to shoot down space installations will be effective. One can reasonably expect humans will keep fighting wars in the future and good fences will still make good neighbors, so they would likely already have defenses installed.
And the Federation can probe and test those defenses at their leisure. Hell, the Federation could set up bases all throughout enemy territory which the enemy would not detect for years if at all.
If not they would certainly do so as soon as they went to war. Phasers would have limited effectiveness against planet, moons, comets and asteroids due to their relatively low power, and space stations would have to defend against weapons of similar levels already.
And how would they do this? Shields? Energy-shields are nonsense-physics already.
As for torpedoes, first I would expect that they would already mount extensive point defense in space and missile defense for planets. And even if they can fire at them, it won't be very effective against the largest population centers. Wow, you bombed the fuck out of the lunar colony. Too bad it is built completely underground to take advantage of shielding. You didn't do a damn thing. The end result of this means that the Federation will have to bring in ground troops and go door by door fighting across a star system. That is not a winnable situation, particularly when you think about the time and travel bottleneck. How are they going to hold what they take?
See earlier point about the Federation having time to deploy every Trekkie wanktech idea they ever came up with.
Sensors. One recurring theme with Star Trek is that the target is using subspace technology, and that is what lets their own subspace sensors spot them. But the opposition doesn't use any subspace. So Trek would be damn near blind, at least until the recalibrate the positronic flux suppressor by 1.21 jiggawatts and discover the telescope. This is a major advantage. It is very hard to fly to a battle and fight when you can't see where it is or what is shooting at you. This is closely tied in with the population point – given that one can expect structures in the Oort cloud, the Federation has to find them. Find them and eliminate them before they can spawn daughter colonies.
They have all the time they need to find their targets. Meanwhile, the other civilization will respond incredibly slowly. In fact, most of your hypothetical super-sized hard-SF civilization would not even know that a war was going on until thousands of years had passed. You really don't seem to be grasping the enormity of the disadvantage here.
Economy. A civilization with sufficient space infrastructure to routinely launch starships and support the expected population it would have by that time has more economic muscle then we have seen from the Federation. It is the same as Coruscant shows that Star Wars could buy and sell the Federation several times over. Tied in with that, what is stopping the opposition from expanding as fast as they can during the war? Even if they are stuck within the star system, their combined industrial output means they should be able to produce more stations. In fact, I would not be surprised if a mature space civilization could spawn more daughter colonies faster then the Federation could conquer them.
Once again, scale is not the same thing as speed. When you compare SW to ST, you are comparing a civilization to one that has superior scale and speed. In this case, that is most definitely not the case; the opposing force will be pathetically slow to respond to anything. So slow, in fact, that a two year long war (for example) could be started, fought, and then concluded against a member system before the next star system is even aware that anything is going on. Did you consider that?
Culture. More people and better computers and interconnectivity means more interactions means more expressions of these interactions and viewpoints, which, after a suitable amount of time has passed since the creator of said expression or viewpoint has died, is known as art. Look at Web 2.0 and the way Internet culture has exploded as a result. The opposition can hunker down, throw out the occasional starship to do battle, fight the invading troops, and export their culture.
Fine, go ahead and completely ignore the effect of communication speed. Again.
Victory conditions. The scenario makes a conventional win damn near impossible. The opposition can't plausibly take out the entire federation. Depending on where they are placed they may be able to knock earth or other important signatories around the head enough to get a victory, but that isn't a good assumption. The fact that one cannot fight an interstellar war means they can't do much for offense. By the time the took out the Utopia Planetia shipyards, the ones they had destroyed first would have been rebuilt. Against smaller hard sci-fi groups the Federation may be able to bring in enough people to win, but there aren't many groups they can do that to. Even a group as poor as the survivors in The Outcasts From Heaven's Belt have the sheer numbers to bury the Federation.
Speed kills. Accept it.
And it is unlikely they would shift to mass murder without severe provocation.
So? It's also unlikely that they would start a war at all. Too bad for you that the scenario stipulates just such a war, fought until the complete destruction or capitulation of one side.
It is my belief that against most of the space operas regarded as Hard sci-fi the Federation would be curb stomped.
That's because most space operas "regarded as hard sci-fi" are not hard sci-fi at all.
But if we define the term hard sci-fi as only those within the limits of what is know instead of the usual fuzzy definition then it becomes mush more difficult. I think in that kind of situation you would see almost a kind of stalemate – Federation worlds and staging areas nearby (within a few light years) would periodically be hit by strafing raids and infowar attacks, while Federation attacks against the target system would be a cross between Operation Overlord and Stalingrad – attacking ships would deal with infowar and defensive fire to destroy or harry them back, while the invading troops would be doing a variation on city fighting where the terrain is much more hostile due to the nature of the environment and the fact that they are so heavily outnumbered. It would be massive resource sink. But in that time the superior economic and influence power of the opposition would come into play. Just as what happened when Sparta conquered Athens, even if the Federation wins the war they lose their civilization. Their culture, economy, ideas, and way of life would be buried by the sheer volume of competing values from the opposition. The free market of ideas would come into play, and the Federation as it once was would disappear. To me, that would be a win for the opposition. They already have enough people that a change in government would be largely unnoticed, but the Dominion War shows that the same is not true for the Federation.
Pure tripe. A civilization limited to lightspeed communications and travel would be utterly fucked against a civilization with FTL propulsion and communication technology. The very idea of launching attacks against the FTL civilization's planets requires many years of lead-time, not to mention some kind of quasi-magical ability to know where the enemy's attacks are coming from. And once more, you're totally ignoring the fact that every Trekkie wank-tech idea under the Sun might actually be plausible if you give them that kind of time to fuck around.

The missile starts out with a velocity equal to that of the ship plus whatever it got from the initial launch. Any changes to its trajectory from there are limited by the acceleration of the missile. If the target is moving in a diagonal with an acceleration greater than the missile can manage the missile will fly past the target without hitting it.

Seems pretty straightforward to me.

Let's take an example:

Initial velocity of launching ship: .92 c
Initial velocity of target ship: 0 (to keep the calculations simple)
Initial velocity of missile: .92 c
Time to intercept if target remains stationary: 10 seconds

Target ship moves off at 90 degrees at 1000 m/s^2
Missile moves at 90 degrees at 100 m/s^2.

The target is therefore accelerating at 10 m/s^2 relative to the missile. The missile cannot intercept the target, it will fly past it at a distance of 49.5 km. I simply cannot see how it would be otherwise.

I don't know where you're getting your figures from, but the Federation covers a 4000 lightyear radius from Earth. It would take six months at warp nine to bring ships in from those distances assuming all the fleet is deployed out to the far frontiers (which it wouldn't be). In any case, that's far better than the years/decades required for the STL civilisation to get anything toward Earth.

Population. Once they do get there, what is the Federation going to do? I'm hard pressed to think of a hard sci-fi series that has a significant space presence and doesn't have more people in a single system then the Federation has in 10 systems. Most of them have single systems that outnumber the entire Federation by orders of magnitude.

They don't have to exterminate the entire population: they only need to inflict enough destruction to essentially send their civilisation into chaos.
I rather doubt threatening to shoot down space installations will be effective.
If enough of the population are in orbital habitats, this is actually a very effective threat.
One can reasonably expect humans will keep fighting wars in the future and good fences will still make good neighbors, so they would likely already have defenses installed. If not they would certainly do so as soon as they went to war. Phasers would have limited effectiveness against planet, moons, comets and asteroids due to their relatively low power, and space stations would have to defend against weapons of similar levels already.
Warp missiles with 100-2000kg matter/antimatter warheads which can be produced in far larger lots than starships and far more quickly solves this problem for the Trek attacking power. In point of fact, they don't even need to send a single starship into the enemy homesystem.
As for torpedoes, first I would expect that they would already mount extensive point defense in space and missile defense for planets.
All of which were never built to cope with automated weapons not only capable of FTL but high sublight velocities and manoeuvering on impulse drive.
And even if they can fire at them, it won't be very effective against the largest population centers. Wow, you bombed the fuck out of the lunar colony. Too bad it is built completely underground to take advantage of shielding. You didn't do a damn thing.

That is not a winnable situation, particularly when you think about the time and travel bottleneck. How are they going to hold what they take?
The Cardassian warp missile in "Dreadnought" mounted a warhead with a 2000kg matter/antimatter charge. The destructive yield of that warhead lies anywhere from 12,000 to 42,000MT (depending on efficiency). Too bad your moon colony just got caught in a blast large enough to tear out a very big crater. And if the blast didn't catch the colony directly, the seismic effects won't be very good for underground structures.
Sensors. One recurring theme with Star Trek is that the target is using subspace technology, and that is what lets their own subspace sensors spot them. But the opposition doesn't use any subspace. So Trek would be damn near blind, at least until the recalibrate the positronic flux suppressor by 1.21 jiggawatts and discover the telescope. This is a major advantage.

This is closely tied in with the population point – given that one can expect structures in the Oort cloud, the Federation has to find them. Find them and eliminate them before they can spawn daughter colonies.
So what if the opposition doesn't use subspace? The Federation has subspace telescopes capable of bringing in visual resolution of any target you care to name from dozens of lightyears away (the Argus array springs immediately to mind) and they have warp-capable probes able to transmit data over interstellar distances in real-time. More than enough to identify targets for a missile barrage.
Economy. A civilization with sufficient space infrastructure to routinely launch starships and support the expected population it would have by that time has more economic muscle then we have seen from the Federation. It is the same as Coruscant shows that Star Wars could buy and sell the Federation several times over.

It's a pity that economy will be in ruins after a large enough barrage of warp missiles destroys enough manufacturing and population centres to wreck their entire civilisation, even if total annihilation of the population isn't the object of the attack.

Something else has occurred to me. Against a hard SF enemy that fights at high relativistic speeds the Federation would have another major advantage: FTL subspace sensors.

A major problem with combat at high relativistic speeds is that light lag tends to become a significant factor. If a ship is whizzing around at .9 c it only has a window of 2-3 seconds to see the enemy's manuevers in real time. The rest of the time he's looking at images of where the enemy was a couple of seconds ago, and the enemy can easily mess up his intercept course by changing velocity or direction a little (especially if he has a higher max acceleration, as a Fed ship probably would). On the other hand, if the other ship has FTL sensors he can track his enemy's manuevers in real time, and react accordingly. Depending on the nature of the engagement, he may also be able to see the other ship long before the ship with c-limited sensors can see him. This is a significant advantage in the hands of a competent commander.

Hate to have to remind you of this, but it didn't take too much provocation for the Federation to decide to exterminate the Founders with bioweapons during the Dominion War, and less than that for the Cardassians and Romulans to attempt it two years earlier.

Well, an enemy might be able to foul Federation sensors with ECM, but that's pretty much irrelevant if the Feddies choose to target fixed installations and planets/moons. Those things don't change course, so you don't need real-time sensor data ahead of you.

I know this may sound like a silly question, but how exactly do we define 'hard' science fiction? I get it's supposed to conform to the actual laws of physics, but to be honest, some of the stuff I read in hard science fiction is so goddamn nutty that it belies belief. Revelation Space is a big offender; for a supposedly hard sci-fi universe it has stuff which is plain ridiculous. I've not read some of the later book with inertia control and hypometric weapons, but even something as tame as the powers suits capable of morphing particle beams and and lasers and mass drivers capable of tossing slugs at significant portions of cee is pushing it. They can also go from ground to orbit with their utterly tiny antimatter drives.

That's apparently 'hard'. Conjoiner drives alone should disqualify Revelation Space. Or if it isn't disqualified, I might as well say that the fucking Xeelee are hard sci-fi.

That seems to be the definition we're using, though to be honest virtually no remotely space opera-like universe actually strictly conforms to it. The only one I can think of is maybe Harry Turtledove's Worldwar Series, if you discount the human-developed FTL drive in Homeward Bound. Though it has plausibility issues in other areas. The Ekumen might qualify too if you discount their FTL communications ability, although again it has whopping implausibilities in other areas (such as humans not having evolved on Earth).

In this instance, not only are we limiting Hard sci-fi to conforming to the laws of physics, but also realistic applications and engineering. No macroscale quantumn dickery, no force field generation, or anything like that.

And it's comically easy to mess with any laser-pusher system for distributing ships. All the UFP has to do is deposit an asteroid behind or in front of the enemy ship (at their discression) or missile, or if strictly necessary, just build their own solar sail, unfurl it behind, and literally take the wind out of the enemy's sails.


And yes. Wong's right. Sod it.

After one hundred years of being annoyed, the UFP fires off some trilithium weapons on warp-carriages. Anyone got an idea on how to stop that?

Want some real fun? Take out or interfere with the decelerator system on the other end, and watch their transport infrastructure fall apart as sleds either zip by receiving planets into deep space with no hope of retrieval or helplessly slam into celestial objects. Hell, if it's a civilization that spans several star systems, the receiving system probably won't even know they're at war with anyone yet.

It may be theoretically possible to create a large and well-developed infrastructure with realistic technology, given enough time. But everything in it will move in super slow-motion relative to a soft sci-fi civilization, and it will be incredibly easy to disrupt. Just think of how much an enemy could fuck up our technological infrastructure today by simply taking out a few piddly satellites. Graduate to hitting a few pipelines and you've got chaos.

Puh-lease. Even assuming that's legitimate (and that website link gives me a 404 to the page that presumably gives more details on the concept), it's basically a bag of antimatter fuel with a wisp-like structure, traveling in a perfectly straight line.
Sorry, link rot.

Yes, it is a legit starship.
Yes, it is built of gossamer and cobwebs, and pretty much moves in a straight line.

-Okay, so a hard sci-fi civ is utterly fucked due to having it's neck in a physics noose while Trek gets to piss all over physics. There was only thing I could think of that might give a hard sci-fi civ a chance: information warfare. Trek computers have completely pathetic defenses against information warfare. If the hard sci-fi civ could manage to take a single Trek ship largely intact maybe it could leverage the gain to save itself. I like this approach for several reasons:
A. It might be possible actually engage a Trek ship with info. warfare or with a clever trap in one of the initial battles before Trek decides to doomsdays everything from a distance. There is a real chance that a Trek ship can be captured sufficiently intact to study its computer systems.
B. Trek info defense is pathetic and their ships are at the mercy of computer control. This is the type of weakness that could be exploited despite massive disadvantages in speed and real physics.
C. Only one functioning Trek ship would need to captured and "subverted" to exploit its comunications speed and to use in FTL info. warfare attacks against Trek targets.
D. If Trek computer defenses are sufficiently weak (and it appears that they are) and the hard sci-fi civ is good enough at info. warfare Trek could be wiped out by subversion of its own tech.

* I haven't thought about this enough so hopefully others will follow up with good ideas or tell me where this plan goes all wrong.
# The OP isn't clear on captured tech maintainance and use. What about things like replicators? They are designed to make new stuff. Could they be used to build/repair stuff that doesn't work in the world of real physics?

If the Hard-SF civilization is willing to commit genocide right off the bat, it could resort to the use of a solar mirror array. Simply put, it's a honking huge array of mirrors that direct sunlight in the desired direction. Having a significant portion of a star's energy hit your planet would make anyone's day pretty shitty. With data from a captured Fed ship, you could feasibly manage to target every planet with a beam before the civilization is blow up.

None of the individual mirrors need to be able to handle a very high amount of photon flux. It can't really be stopped by the Feds short of evacuating every single planet.

The problem is that the HSF civ will not be able to negotiate before doing this, because it's a relatively simple system to disrupt (though it's a very very large system, which will therefore require quite a bit of time to destroy (on the other hand, it's mostly metal film)). Of course, it also means the UFP destroying the originating system will not stop the attack. The attack has already been launched, and nothing the UFP has can stop trillions of teratons of energy from blasting the target system into a wasteland. A side effect would be that any starships near the target will probably also instantly be vaporized, thereby keeping the UFP from understand who's attacking. Given Warp, UFP ships are unlikely to be far enough away to avoid getting fried while still be close enough to be able to determine that the attack is under way and which direction it came from.

I did mention this is a very large system, right?

Could you actually make the beam tight enough that it would give an appreciable dose of energy to a planet light years away? I'd think beam diffusion would be a huge problem over those kinds of distances.

Getting sufficient pointing accuracy to hit a planet with vast swathes of metal film would be extremely difficult, bordering on impossible, even for the closest systems. I can't see this taking less than several years to construct, in which time the Federation can trivially disrupt it just by ploughing through it at warp repeatedly. They don't even need to fire a shot. Meanwhile even if it did somehow get a shot off, it will cook exactly one planet. The Federation will then warp into the other possible beam trajectories, drop some sensor probes, work out what if any other light pulses are on the way, then take steps to divert them. At minimum they can be blocked with a sufficient area of exactly the same metal film that formed the beam in the first place - which can be arrayed in deep space, without needing to be supported against gravity, without needing any sort of pointing accuracy. But being the Federation they'll probably do something involving more technobabble instead. They've got decades until the pulses reach the nearest systems, hundreds to thousands of years until they reach the further ones, so this should be quite easy for them.
