So, I fixed Radiator KKVs going after nearby dead comrades. The key is to make a super low output generator with a low output temperature. I picked 100K in is this case, but could easily go lower. Blasts 2-3 meter diameter holes in gunships now with a 2-3Km/s intercept and ~5Km/s impact. Interestingly, I've never seen these missiles make a triangular impact hole. I assume the game converts the missile to an equivalent round flat plate before doing damage calcs. Would you reupload the image for your KKV? The link is broken.

The Key detail is the 100K or colder radiators with a nano-watt generator. Makes the missile a dimmer target than the ship you're aiming for. Also I used three radiators, because the pitch and yaw moment of inertia is almost the same which helps with stability.

Thank you. I will have to try it out some time tomorrow.

(Post 1/2) First post here. I've been lurking a lot, trying out different derivative designs of what is posted here. Anyway, this KKV hasn't really been optimized in any way, so it's more of a proof of concept than anything else. It's a fairly big vehicle, with 7+ kms of delta V, and four launchers carrying ten 1kg Osmium rods each, for a total of 40 small Osmium Impactors. (If it looks poorly designed, it's because it's a copy of a Space Sword derivative from this thread crudely converted into a impactor carrier.) The vehicle is set to homing. At 30 km, the launchers empty their magazines in a little over half a second while the bus goes into it's impact burn. The unpowered impactor rods follow it closely at a slightly lower speed.

The result is pretty promising. A single vehicle oneshots stock Gunships pretty regularly when it hits, which I think is pretty good for a non-optimized weapon weighing and costing only x1.5 that of e.g. a Sword Missile. This is a relatively typical single hit: As you can see, even though the main vehicle appears to have glaced off the armor down by the radiators, the cloud of Impactors has littered the Gunship with holes. Most of these have exit holes as well, and the Gunship has lost its forward fuel tank, as well as all three of its Crew Modules, which are dispersed throughout the craft. This kind of kill is very common. I also tried it on a target station using the last armor layers posted in the Cap Armor thread, and parts of the payload punched through on the other side on this as well. Has anybody tried this before? It has most of the regular drawbacks of KKVs, including following the leader due to heat, but they can often deliver solid hits even after getting killed by lasers.

So a kinetic MIRV? Interesting.
Does those osmium impacter that you throw out is literally just osmium radiation shield?
Would you mind posting us the design for the launcher and projectile because I have been having trouble throwing the kinetic rods at the right time?

Would you mind posting us the design for the launcher and projectile because I have been having trouble throwing the kinetic rods at the right time? Yeah, they are just plain radiation shields. Nothing else. Here's the launcher. I suspect everything can be made a lot better, since it's literally the first thing I threw together. That said, optimal release time will probably always be highly context dependent. Too early, and they won't benefit from the last course corrections, too late and they will be laser food. Well, they will probably always be laser food, but I refuse to let that stop me from trying to make KKVs. All suggestions for improvements are welcome. Is there any way to force drones to have "homing" as their default order instead of broadside?

Well, for one I believe that you can improve your launcher by using iron as stator and zirconium copper for the forcer.
That should cut down the weight of the ridiculously heavy launcher by half or more.
I don't even know why cobalt is used for coilgun round when it's utter crap compared to the cheapest material in the list, iron.
Also there isn't anyway to set drone to homing automatically. Which is why I put a super light gun on my drone so that even if they automatically start as broadside, they will try to get into the firing range and accelerate anyway.
Also making the drone not defensiveness after firing the payload. It has tons of delta-v, might as well use them.

Especially since I have a target launch speed of approximately 1.5 m/s. With the improved performance, I can reduce the size og both the stator and forcer to minimum, saving around 9 kg, as well as reducing power requirements to 1kw, which means smaller reactor and radiators. This means I can triple the number of impactors while retaining the same performance otherwise. The gun-trick didn't work for me, however. I don't quite know why, as I've seen it on other drones.

Hmm, maybe just put a tiny guns anyway so when you home in your MIRV missile, you can shoot enemies in the meantime for more damage to insult them?
EDIT:
Tried out the design, actually works quite decently!
Though I can't test whether the osmium rods might be destroying each other since there's tons of spark, but there's more than enough kinetic rods left to kill off the target.
I had to accelerate to nearly 3 to 4 kilometer per second to make sure the kinetic rods actually hit instead of getting dodged by the enemy warships though.

I had to accelerate to nearly 3 to 4 kilometer per second to make sure the kinetic rods actually hit instead of getting dodged by the enemy warships though. I actually go for suicide burns against the target. The delivery vehicle frequently misses due to the extreme velocity, but the target still gets hit by enough the over 100 impactors going at 7 kms to be destroyed quite regularly. I made two guns to try on the drone at around 2kg. One railgun and one conventional. For some reason, they caused the drone to maneuver too drastically at the terminal phase, resulting in overall less lethality. This kind of last minute maneuvering also seems to increase the impactors colliding with each other. The high velocity option and no gun option seems to offer more effective impactor hits. This is the current version of the delivery vehicle and the launcher. Your suggestions has nearly tripled the amount of impactors without reducing delta V or increasing mass. It seems far more lethal from the early tests, though I'd love to have a slow motion option, or at least a pause button available. Stuff happens awfully fast.

I want to try a design like this. Can you share that engine?

I worked on a design that's basically a version of your missile that weighs less than 250 kg, carry some 60 osmium rods only.
It can one shot most ships, but sometimes only the engine get destroyed, leaving the enemy ship stranded in space.
I can only imagine just how cruel it must have felt when I sent in another missile to rip the enemy ships apart.
It was swiss cheese by the end of it, pretty amazing result compared to normal KKV missile which just make one neat tiny hole through the reactor.
Now I'm hoping to see if other shape of osmium penetrator would do more damage or just looking weird.
I have been wondering if I could make a sword shaped projectiles and throw that into enemy ships...
Oh right, someone did already. Heheheheheheh....
