Coilgun launched 10kg frag missile I've been working with this idea as well, but haven't gotten very far due to lack of time to play with the module designer. My thinking was something that has ~1-2km/s of deltaV and a very very high acceleration (like it burns all its fuel in half a second). The idea was that the coilgun is effective even with an unpowered projectile, and aims to hit as if that were the case. If we're still on course in the last few seconds, then great, the engine will add another 2km/s to the impact velocity. If the target has moved while the projectile is approaching (or the guns aim was slightly off), then the projectile has some opportunity to correct with a last second high acceleration burn.

Well its power use is 440 kW and output 275 MW. 624.000 % broken. [bnr] Well damn. I'll have to reoptimise my secondary batteries. Just reduce their rate of fire and you should be fine. Granted, you'll have to reduce it by a lot, but that also means that long-range engagements aren't going to kill your computer from the sheer number of slugs being launched.

my lighter less expensive solution using amorphous carbon armature gets better speed at lower pressure can punch through some really hefty armor but whipple shields counter it decently. not as fast or accurate as first post but relatively affordable

You have to put this in perspective, there is other way to get extremely fast projectile at a much lower cost.
I have drones that pack 8km/s dv, with guns trow 10g projectile at 2.6 km/s. Now, if I intercept at 8km/s and fire, the projectile will hit target at 10.6 km/s. And that's not the top end, I did a 28km/s intercept yesterday... It does not matter if I start firing at 400km, at that speed travel time is so low that bullet dispersion is minimal. A coilgun with the same bullet weight and speed will cost a hell lot more.
For guns, range does not exist in space, only dispersion.

in perspective im testing this against armour that bounces 1kg osmium rods at 5 km/s with no slope 3kg rods can punch through about the same as these 1g projectiles - with slope i still havent found a way to defeat it reliably
so 10g progectiles at even 10 km/s are space dust in comparison
using 2cm osmiom 2 cm vanadium chromium and 30cm uhmwpe which is a tad expensive but decent in weight and dam near invulnerable

We're not flying aircraft, we're riding rocket-bullets along vectors. *I suddenly have the urge to dig up some of my Stinger-derived early conventional cannon designs*

I'm still using the 33mm cannon which I modified to be smaller, lighter and better.
Same drones mounted with are still kicking asses with 150 times cheaper and several dozen times lighter.
It's not awesome, but it is practical.

Of course, the law of conservation of energy will slow down your ship/drone by the same amount, that's one thing that I use to make my drone strafe. I have RCS just on the rear so my drone strafe allot when shooting. Anyways I am side tracking. Trowing off course is a option, focused fire is another, over time a gun can dig trough anything. But the option I prefer is combined strike, you send missile and you shot. That works against the most armored ship. As for armor, I only use Boron for hard fire , Amorphous Carbon for laser and nuke, graphite/silica aerogel because its cheap and light, and finally space, its good between layer and its even better between ship!

the only time i have thrown a ship onto a spin was with nukes and 5 ton projectiles often the fuel tanks being pierced will set a ship to spin though mostly my point was that these hyper velocity rounds are very effective having a variety of weapons is good but i like to test things in worst case scenario a variant of that armor was effectively immune to nukes and could withstand more fire than a fleet of stock ships could pour out and still be practically intact- (explosive penetrator nukes did work sometimes they act strange though) so i found that these hyper velocity rounds were one of the best solutions i am curious as to what kind of max speeds and what materials are good for these. there is a point in scaling where you cant make armor any stronger but its fairly high i suspect that its higher than the max you can get out of any conventional weapon this is where accuracy is important ships have radiators and gun ports that are fairly limited in how much you can armor them which makes lasers practical at that scale - i can have armor thats practically invulnerable but my radiators will get shot out eventually and these high velocity rounds are fairly good at that.
