I originally just want it to be able to handle a few stray round as it was well, a carrier drone and not a combat drone. I then decided to up its protection to slightly below my old capital ship design which are tough as nail and well... It become a comically tough nut to crack. Whats the old capital ship design thats tough as nails ? whats its armor scheme ?

I then decided to up its protection to slightly below my old capital ship design which are tough as nail and well... It become a comically tough nut to crack. Whats the old capital ship design thats tough as nails ? whats its armor scheme ? Practically the same thing, except the graphite aerogel layer is up to 1.4 meter thick. Now I reduced the thickness of the aerogel layer to 50 meters each, and the sub-capital drone is still able to absorb hits from multiple ships like nothing. Things changed however when I sent it against a stock gunship. While the drone's armor didn't get penetrated, the gunship has so much firepower that all the guns were stripped off and sliced the drone in half just seconds before the drone could correct its course to smash into the gunship. It was a shame really, there's only a distance of 100 meters when the drone hull flew past the gunship. All i can tell from this test is that heavy projectile is crap against it, but repeated gram sized projectiles at the same spot are dangerous as hell.

All i can tell from this test is that heavy projectile is crap against it, but repeated gram sized projectiles at the same spot are dangerous as hell. but in the test vs the gunship, it sounds like it died from the guns being shot off, and then the projectiles going thru the holes where the guns were. if thats the case, then (and correct me if im wrong) my idea was a succesful one, and the reduced gap distance still afforded it adequate protection (like you said "sub-capital drone is still able to absorb hits from multiple ships like nothing"), while reducing mass. The drones death to the gunship in your tests was do to the guns being shot off, which is a totally different prob (not being able to have composite armor on turrets). so it sounds like my idea was a success.

That and some hits for some reason managed to knock the drone onto its vulnerable flat side.
Despite, you know, the drone weighs at nearly 400 tons.
The shots basically penetrated straight through its sides, as well as ripping its guns off and mission-killed it.
Still, it's a tough nail to crack and serve pretty well for its purpose.
Though I most likely will get a lighter armor composite for the other variants of the same carrier drone because the armour increased the weight of the drone from 333 tons to 381 tons.

Please, help. Is it realistic, that 625mg tungsten shrapnel on 35km/s cannot penetrate 3 layers of 0.5mm graphite aerogel with 10m gaps? Is whipple shield so effective, or its simply a bug?

You got something incredibly tiny at high velocity hitting what is something extremely really thin. 10m is something more than enough to disperse the plasma. So yeah looks like the whipple shield should be stopping it.

Also, 10 layers is enough to tank even 5g on 35km/s. Ship looks like a vacuum zepellin, but it not affect anything important, heh) And thanks for answer.

Yeah turn down the speed to like 2km/s and you'll probably see a big difference. For the 5g at least, cant guarantee the 600mg

Something about armor I've been curious about, but have never been able to definitively confirm, is to what extent armor layers interact with each other. For instance, I used to use a thin layer of high-melting point armor backed by graphite aerogel (with its crazy thermal conductivity) to serve both as a heat sink, and a way to "spread" the heat away from the laser spot-point on the external armor. Currently I use an internal layer of silicon aerogel on my missiles to insulate internal components against laser heating. However, I'm not even sure that kind of interaction is modeled.
It gets even more dubious with kinetic effects - for instance, spall liners. Nominally, if the armor and the internal spall liner behind it are directly laid atop one another, the spall liner will enhance the other layer's strength - they'll tend to either resist or fail together under impact stress. I've no idea if that works in-game, though, or if projectiles are simply modeled as encountering one armor layer after another, with shrapnel spread/plasma shock effects applied as necessary for the indicated spacing.
This determines the difference between use of more complex composite armor schemes, or using fewer, thicker layers of armor. My testing so far favors the latter, but I'm not sure if this is because of how the game model works, or because of my own miscalculations.

Composite armor tends to work better in my opinion, but going too complex with your composite armor and you probably can't test what is helping what part already.

Yes they do interact between layers. I coat my armor with 500micron aluminum coat, the same material used in 77nm laser mirrors. It works really well against those extreme UV lasers.
Now, aluminum is a good mirror, but it cannot withstand that much heat. Aluminum alone would melt instantly under such laser. (As proven by stock designs) Graphene and 3d-graphene filler under that aluminum on the other hand have really high spec-heat and thermal conductivity. They absorb the heat from the aluminum layer and spread them all over the hall, making the aluminum last much longer.

Mass also plays an important role.
Its illustrated pretty decently by my graphene armor scheme ( probably broken to begin with ). Top to bottom. 2cm Si-gel. 1mm graphene 1m void 4mm graphene 5cm Al-foam. 2mm graphene.
Is generally quite sturdy. However changing the 4mm graphene layer by a 4mm maraging steel layer led to less leakers.
The physical stats of maraging steel are worse ( very respectable overall ofcourse ) but I think the ~35x sectional density offered by the maraging steel does more to slow down projectiles in combination with the Al-foam and graphene backstop.

Honestly, I just kinda want a good armor composition that's light, and well, don't end up in black.
My armor composition with diamond, amorphous carbon, graphite gel and boron is super good, but it's kinda dull when everything is black...
