pretty self explanatory - can you create a missile capable of at least lets say 1% c and hit a target- you might need to fire from the the opposite side of the solar system.
bonus points granted for acceleration.
im curious to see if something like this could even be usable.

I recall a mention a while ago of someone creating a H-fueled MPD that could drive a ship to 0.02 cee, but the issue was that you'd need several EXAwatts of power (as in more than 100000000 of the most powerful reactors we have available right now) to make it work.

"useable" probably not but this meets your criteria of over 1% c (I just slapped a few 10Mt nukes to the head of my explorer drone)  |

Yeah that was me, the thread on it is here they kind of shut down the idea of taking relativity into account since it isn't practical to power anything close to caring in game, though I have been pushing the bounds of what is practical in game. Without taking relativity into account you could get to 1c with ~400PW off the way MPDs are working. The 303Mm/s exhaust velocity thruster would end up giving the thruster a max velocity around 4-5c (assuming enough fuel was provided). Though it wouldn't really need to go anywhere or any amount of fuel to break physics right away since the hydrogen would be propelled with greater than infinite energy if relativity was taken into account. As soon as it would be turned on physics would be broken.  childrenofadeadearth.boards.net/thread/507/bug-exceed-speed-light-thuster?page=1&scrollTo=6041 |

ok i guess the real question is how much speed can you get in 1 day give or take - that seems like a reasonable time frame.
geting to super high speed in a reasonable time frame might be impossible without an orion drive or a nuclear salt rocket.

i mean 51 years to accelerate 200mt of nukes plus shear kinetic power - i supose you could destroy a moon with that
oh add a few hundred years of coasting out into deep space so that you have a long enough run to accelerate towards the target.

hitting the target part is hard.
missiles keep spawning at 5km when i need them to be like 100km out
also the fact that it wont let me plot fastest intercept right off the bat is annoying im working with 40km/s dv right now geting a fly by or intercept just doesnt work - it simply wont let me plot it accurately - by the time i have the course close enough to tell it to plot fly by it will just miss. fine tuning by hand still cant get it close enough.

By the normal definition of 'relativistic speeds' is usually when relativity starts to kicks in, which is usually about >0.3c, far more than any practical method in Children of a Dead Earth.
The speed in this topic, scientifically, should be called 'fraction of speed of light'. And getting one of these type of things to hit a target is absurdly hard on its own.

hmmmmm stage a high g maneuverable rocket with lets say 20km/s onto a low acceleration carrier? hmmmmm you would need to station the thing out past sedna and 20km/s wont buy you much accuracy at the end......not to mention the months or years needed to get the carrier up to speed. relativistic is probably out.
i realy want to see a single large slug get turned into a ball of plasma that disintegrates a ship on contact but this is getting tricky
need to see if i can get black box weapons working to see how much speed i need to get that effect - probably to much.
i cant even get a hit at 40km/s - although at around 10km/s things are starting to act more like bombs than penetrators ripping out huge chunks of the whipple shield or creating large hot spots on the opposite face of the armor when they break through.
if i could hit at that 40km/s i think it could achieve goal of vaporizing the enemy. - speaking of any one know how big a nuke it takes to vaporize a chunk of a gunship? things seems to be very resistant to geting melted.
slower penetrators are more effective than my attempts to shock large kinetics strait into thermal damage. But science demands i vaporize things.

1g traveling at 3Mm/s would hit with 4.5GJ of energy... the sheer kinetic stress of something like that passing through your ship would shatter everything it hit like glass...
not to mention every pressurised compartment in the ship would burst due to hydrostatic shock .
