I've been working on a small countermissile and one idea I've had is to slap a launcher and internal magazine onto a drone. Any missile that seeks drones will seek other missiles, so countermissiles could have a dual benefit of both potentially killing other missiles and acting as decoys. ...heck, so far as that goes, is there anything preventing us from mounting flares on missiles? Since radiance is subject to the inverse square law, mounting a long-burning, low-intensity flare on a missile could still foul other missiles' seekers if it gets close enough. ...I'm going to take a look and see what I can do with this when I get home. If nothing else, getting the flares AWAY from your ship is worth a 50kg of fuel and a half-kilo rocket motor. I already looked into this pretty soon after launch, basically the biggest problem is that flare fuses are auto triggering which is dumb. So as soon as you launch the missile from the launcher the flare warhead detonates. Alternatively trying to make a slow burning payload for a missile is infeasible, because missile payloads don't have a retarder mass option. Hypothetically i guess you could mount a flare launcher on a missile, but it is nowhere as efficient mass wise, like installing an entire cigarette lighter into a firework just to light it off. It works, timing is a problem, but not as fatal as it sounds at a first glance. The enemy missiles are wasting Delta V to aim for your flare/missile and when the flare dies, the next is already coming behind it ... usually the third in the row gets them. Even if any of them survive the explosion , they are already on a vector way aside from the ship and usually your point defence gets them. More seconds out of the flare would make all of this more efective for sure, but the missile will be bigger too. Attachments:

Do you have any designs I can use for that? Here we go, the smaller nuke The cheap missile The high dV missile Can I grab a copy of that heavy water rocket design? I'd like to try those missiles out. Thanks!!

Here we go, the smaller nuke The cheap missile The high dV missile 10 of these are almost 8 times cheaper than the 1 GT missile I use at the moment with 3 times more deltaV. They even have more acceleration. Impressive. You could improve it further against lasers by adding a thin sheet of silver, follow by a thin (1cm) layer of diamond (very high thermal conductivity). I tested this and it made missiles difficult to destroy even with dozens of 14mw lasers, and impervious against the AI even with multiple solar lances.

The best laser defense without question is silica aerogel.

My 0.5mm silver/1cm diamond/2cm silica aerogel missile lasts longer than a pure 10cm aerogel missile

Whats the best dissipation-to-weight radiator materials for high-yield stuff like the Doom laserstar?

AFAIK, in-game radiator effectiveness depends on surface area and thermal conductivity from the coolant pipes to the surface (plus some measure of coolant pipe size; I have found 2cm gives near-optimal results, although I am not certain whether it has an interaction with armor thickness). So dissipation/weight depends on how strong you need it. For a given armor thickness (or mass), diamond should give you the best per-area performance, but in my experience the falloff to the ~200W/m^2 materials is very slight (with the further falloff to ~20W/m^2 noticeable but still very small, particularly for radiators without much armor). Amorphous carbon seems a very good choice (particularly for hot reactor radiators, where there are not a lot of other options), although I somewhat wonder if it is more prone to snapping under kinetic fire than less brittle materials. I found that silica aerogel is sufficient in most cases, but silver + diamond as a thin outer layer can improve performance even further. My 0.5mm silver/1cm diamond/2cm silica aerogel missile lasts longer than a pure 10cm aerogel missile Do note that your reflective armor weighs 4.75 times as much as the 10cm aerogel... that sort of substitution is useful if you need to save space (in which case you should also be testing polytetrafluoroethylene, or aramid fiber if you care less about cost), but if you are mass limited (as the rocket equation means you tend to be) aerogel is really hard to beat for small objects.
