How? They're still perfectly capable of staying out of range.


If the enemy wants to stay at range and come around the asteroid, then they have to make a FAR larger orbit around that same asteroid. Whereas a ships that kissing the steroid surface has to make only minor manouvers to move and stay concealed by the asteroid.

To put it simply, all the speed advantage of the enemy is made null and void, because they need to cover a far greater distance to expose the same 2-3° of fire.

Of course, if the enemy outnumbers you too, that's another kettle of fish. You'd need more asteroids :P

With really big rocks and several such ships, you can practicyl force the Umiak to close - everything else is a collosal waste of ammo and fuel.
You may only have to turn a little bit, but you've got a massive and unwieldy piece of dead weight to move around. Miles thick asteroid? That's a really big weight. I'm not sure Human starship drives are going to keep up with Umiak ones with that kind of handicap at long range.


Why would the humans even try to chase?




Quote:
You also miss out on an important fact. Nothing about this engagement dictates that the Umiak have to charge at the human ships. The Umiak could simply ignore the human ships, and start accelerating towards an inhabitable planet. That dictates that the human ships will either have to make a beeline for the Umiak in pursuit (suicidal), or offer to surrender in exchange for earth/Mars/Alpha.


I there's nothing else in the system?
Of course, this is a rather static/slow type of tactics, so it's not suitable for intercept. IT's very defensive in nature.

Better than that. If there are nothing else in system, there are no need for moving.
Bore hole on the asteroid for powersource and crew and put surface full of guns.
Umiak can come or ignore it on their whim.

You can also put them on angrave points or orbits for planetary defence.

With their weapon range, all the Umiak would have to do is make a flyby, potshotting the human ships on the way to the real target.

They don't need to outnumber you. They need two ships, and not particularly big ones. Or torpedos.

This is a completely worthless tactic...these asteroid-ships are effectively immobile and can easily be taken out from far beyond the effective range of their weaponry. The Umiak would have no reason at all to close within mass driver range. They wouldn't even have reason to engage with such worthless warships unless it was to clear them out from around a more meaningful target, and there's no need for them to close to such extremely short range to do that.

Since we (humanity) currently have bunker busting bombs capable of destroying people hundreds of meters below the surface of the Earth, I believe the Bugmen would have something that could deal with an asteroid base in a fixed position. Frankly, I feel humanity needs to build a bunch of large hadron colliders and create enough black holes to make our territory unattractive xP.

The enemy doesn't need to outnumber you to flank the asteroid ships.

Image
-3 Terran asteroid ships vs 2 Umiak ships. Their rocks provide them protection.


Image
-But despite being outnumbered, the Umiak are STILL able to flank and destroy individual Terran ships.


Image
-The only way having more ships offers additional protection, is if you physically bring your ships together in an asteroid Phalanx.


Image
-But while this provides better coverage, it results in more catastrophic damage should an enemy torpedo get through.

The same could be said for the Umiak. They could simply bombard from a distance, or...
TrashMan wrote:

simple. You would bypass the system. You'd take your fleet, fly away from the Terran asteroid ships, and go to the next system. There isn't actually any pressing reason to engage the Terran ships floating about in an empty system.

The problem with this is that while your guns nestled deep inside the asteroid are secure, they need to expose themselves to fire on the enemy. No it'd certainly be advantageous to only open up when the enemy was in range (neutralizing their ranged advantage), the Umiak have other options.

Namely as you said, they could bypass the defenses if it was placed somewhere irrelevant. Or if it's a major colony (Alpha or Mars) they can fire torpedoes at the colony and when the dug in guns pop out to shoot them down, the Umiak can blast the exposed guns from long range with beam weapons (presuming they can't just target the gunports directly and blast them in. Even if they're deep in enough to not be destroyed, the damage to the gun ports will prevent you from bringing them up to fire ).


This isn't to say that defensive installations can never be useful. It's just if that's the only thing you can bring to the table, any enemy (much less a massively more advanced one) will eventually be able to pick away at them.

"angrave points"?

Anyway... http://img853.imageshack.us/img853/6957 ... 937078.gif
Effective range on Terran mass drivers is <10000 km. Max range of Umiak plasma weapons starts at 7 times that and goes up to just short of 29 times that, and given the relatively weak and immobile nature of these targets may be even higher. To force attacking Umiak vessels to just barely come into mass driver range of any human ship to attack another ship would require a spherical formation 540000 km across (so distance to a ship at the center is Umiak weapon max range + Terran weapon max range, putting Terran ships on the edge of the shell in engagement range of the attacking Umiak), packed so full of human asteroid ships that Umiak can't get in any spaces. And even then, a few Umiak gunboats charging in would rapidly great holes in the formation at little risk, allowing other ships to potshot all the other ships without exposing themselves to return fire.

Volume of a 280000 km radius sphere is 21952 times the volume of a 10000 km sphere. Spheres don't pack perfectly, so there'd be overlap and gaps, and you'd want to pack them tighter so the Umiak can't stay at extreme range, so at a rough estimate, you'd need around 30000 asteroid ships to force the Umiak to enter mass driver range. Again, briefly, until they rip a hole in your formation and start zapping your ships from beyond range of return fire.

You're talking about packing space from Earth to lunar orbit with ships spaced so closely that an Umiak ship can't slip through without getting within 10000 km of one. It's not workable.

And if you want to cut down on the number of ships by making a hollow sphere, an Umiak ship that runs the gauntlet and reaches the center can then target any human ship in the formation, forcing them to turn their vulnerable sides to Umiak vessels that remain outside the formation. And note that ships near the "surface" can still be targeted on opposing sides even with this enormous sphere by Umiak vessels attacking along tangents to the sphere...it's nowhere near big enough to force them to come within mass driver range to do this.

Only of interest for long term orbits and minimal-energy trajectories. Granted, if you're pushing asteroids around, minimizing the energy required will be of interest. A bigger problem is scale...Umiak weapon range is far larger than the useful regions around the Lagrangian points, it's roughly the distance of the Earth-moon L4 and L5 points from Earth and the moon themselves. There's no room for a vast fleet of asteroid ships large enough to force the Umiak to come within mass driver range.

How much do you really expect them to increase the range by doing this? Do you really see this making any sort of difference?

Even 3x range makes some difference. If Umiak will stay out of that, only some of their weapons makes any significant damage.
They may damage satellites on near earth orbit, but no targets on surface. That gives us little or more time to react. Like grovel, shoot missiles or escape.
If they try go between or from the poles, they are in crossfire.
And max range of mass drivers in space are infinite, so we can get some lucky shots and also destroy any ship who has lost its controls.
(Escape velocity from sun system is only 525 km/s)

3x the range makes no significant difference, it's still half the max range of the shortest ranged Umiak weapons, 1/10th that of the longest. The Umiak can still blast the defenses to bits from far beyond mass driver range, it'd still take a completely impractical number of ships to make a formation large enough that the Umiak can't do this. And even if these asteroid ships were somehow protected against Umiak weapons from beyond mass driver range, targets on the ground are not protected at all, unless you think these things can mount enough point defense to stop Umiak torpedos.

Building vast fleets of useless ships on the off chance of getting a lucky hit or two is not a way to survive a war.

I don't know why you think solar escape velocity matters, but your figure is wildly wrong. Solar escape velocity at the distance of Earth and the moon is only 42 km/s.

It's infinite against stationary targets. The problem is that requires the Umiak to not bother moving for an hour after the humans fire at them.

Sacrificing mobility for protection in something specialized as an immobile defense would make sense if you had a weapon with longer range than that of the enemy, but even with major improvements, mass drivers are drastically shorter in range...leading to the enemy bypassing you completely or pounding you into scrap from outside your effective range. Heavily armoring one side doesn't work, the enemy can come at you from multiple directions...putting the ship on the side of an asteroid just doesn't work. A thick rock layer all around the ship/station might offer protection for interior sections against plasma weapons at extreme range, but it does little to prevent your weapons and engines from being taken out...they need to be exposed to enemy fire to do their job. Such an approach just means there might be survivors to helplessly watch the Umiak cruise past after wrecking all opposing weapons and propulsion.

The only variation I can think of that makes any sense at all would be heavily armored, non-maneuvering orbital torpedo launchers. Such a thing might have enough armor to withstand enemy fire at extreme range for a considerable amount of time, while retaining the capability to launch torpedos protected in its interior. Unfortunately, if humans can construct competitive torpedos at all, they can't mass produce them in any useful quantity, and the Loroi don't appear to have a whole lot to spare.

I was talking about 1 vs 1 engagements.

The only way a Umiak ship could expose the defending terran ship is to come in close...very close.
Otherwise...yes, it could stay at range and fire..

but any ship will have a problem with that for 2 reasons:
1) heat managment
2) ammo

Just blasting your way trough such a huge asteroids would take many, many shots, regardless of the weapon you use.

Terrnas would have the same heat problems, but their lasers and mass drivers wouldn't "waste" shots.
IMHO, human laser range has been nerfed for the purposes of the story :ugeek:
We could hit hte moon with the laser in the 1960's (1m end radius)


I would also like to point out that Umiak don't know anything about human tech. They don't know how dangeroud they are or how fast, so they could ill-affor to let them behind their lines.

So they would msot likely do exactly what they did in this comic with the Loroi ships holding a line - charge at it.

The low projectile velocity of their mass drivers means precisely that the vast majority of their shots will be wasted. The only way they can land a single hit at typical Umiak weapon ranges would be sheer luck. The short range of their lasers means that every shot fired will be wasted.

Are you serious? I could hit the moon with a pen laser. It's 385000 km away, but it's 3500 km across! Pointing accuracy of within half a degree is nothing to brag about. The beam from Apache Point is 6.5 km wide when it reaches the moon, and far too dim to see...we can only detect the reflection with photon counters.

Effective range with lasers isn't just a matter of hitting a stationary target anyway. You need optics that maintain their properties while handling very high powers, with large apertures due to diffraction limits, and accurate fire control systems capable of tracking a maneuvering opponent. Bigger optics (lower power density, tighter beam) will not only be more expensive to build, they'll be bigger targets for enemy fire to damage. Terrans don't have these weapons, their ships are designed to engage an enemy at much shorter range, probably an internal threat from a planet they're already orbiting within Terran weapon range of. They might be able to simply scale up existing systems to get something with some degree of effectiveness at longer ranges, but that'll take new tooling and possibly entirely new manufacturing processes, and it'll take time.

Why would the Umiak only send in a single capitol ship to attack humanity? What with their ship building capability and that a single ship wouldn't be able to meaningfully take advantage of the Terran systems once they were militarily defeated. Terran space is big. The Umiak would need at least a task force of vessels to be able to patrol the surrounding systems and the colonies. They'd also need ground troop garrisons on each of the six major worlds to provide first hand control over the population. And that's not even counting all the administration/infrastructure/logistics they'd need to build up in order to have a permenant base of operations in human space.


Regardless, the 1 VS 1 engagement is unrealistic due to the fact that all but the smallest Umiak capitol ships carry Gunboats.*


*There's also the fact that the Umiak could just fire a torpedo rather than risk close combat against railguns.

Human weapons aren't nerfed. They're less advanced than aliens with tech generations ahead of what we have.

It's also not a matter of how far out your laser can hit something. It's how far out it can hit something and do meaningful damage due to defraction of the beam.

Not knowing the enemies capabilities and charging in maniacally aren't' they connected strategies for logical beings like the Umiak. The Umiak charge against the Loroi because the Loroi have weapons with higher effective range. Because they can't survive a standoff fight against them.

The Umiak aren't going to try to dice it up in close qaurters with a good reason (note the encounter between the bell and the UFO). It's dangerious. Unless the humans provide some kind of a threat to draw them in, they're not going to suicidally come charging in.

Moot, as no shots would be fired by hte terran untill the umiak ships is within range. Only then would the ship turn, exposing it'self to Umiak fire and vice-versa.

You assume that Umiak will play nice to your tactics. But they won´t. That´s why your argument doesn´t work.

For clarification, I am talking about non moving gunned asteroids on langrangian points for planetary defence, because starship pushing an asteroid around and using it as shield is just crazy.

My point was that even effective (to hit) range for human weapons are small, they are no less dangerous in longer distances.
If effective range is 30,000 km, any umiak ship coming to 90,000 km from earth is soon destroyed in good hit or from being in crossfire.
Over that range they cant make any damage on ship with any armor close of earth.

I mean that we could shoot at umiak home planet without using solar sling. This still takes millions of years and will probably miss.

Okey. I didn't see that last time.
Max range: range at which weapon may inflict at least 1 point of damage.
My mistake.

H6-Mass driver 6kps

Does that means 6 km per seconds?

The Terran ship will be scrap by then. The other ships will have pulverized it. Or the torpedos.

Just how does that work? If effective range is 30000 km, effective range is 30000 km, Umiak ships aren't going to be reliably destroyed at 3 times the effective range. Earth and the moon (and the reach of the Umiak plasma weapons) are over ten times that distance from the Earth-Moon L3, L4 and L5 points, L2's on the far side of the moon and out of range of it, L1 is slightly better positioned for attacking the moon but still hopeless at defense with such short ranged weaponry.

You mean lead the target? You can only do that if the enemy doesn't change their acceleration during the minutes to hours it takes your projectiles to reach them. And yes, that means 6 km/s, just short of 14 hours to cross 1 light second.

I understood.
But 30000km is nothing for defending the Earth-Moon-System. Distance Earth-Moon ist 380000Km. Lagrange Points are in the planetary plane, and L1 and L2 are 1,5 million Km apart from Earth EACH.
That leaves a huge gap. ;)

So Asteroids are of no use.

Another thing is Moon. Moon has to be armed, otherwise attackers could use it as a shield or even as a base.
