Has anyone had success in armouring turrets against hypervelocity impacts?
I've got 12km/s and 24km/s railguns and have managed to armour the spacecraft hull reasonably well against them (multiple whipple shields works well), but the turrets for various weapons get vaporized quite quickly. With anything less than ~30cm of turret armour, the 12km/s railgun can usually destroy the turret in a single hit.
Anyone had success here?

What caliber are these railguns?

4mm and 6mm. 1 gram and 5 gram rounds respectively.

And what material are you using for armor?

So, some initial findings ... this game is making me google for various research related documents far too often ...
After seeing the stock 11mm railgun turret take quite a few hits, I found it uses Boron Carbide. Not very impressive tensile strength, but it does have a high speed of sound. This is apparently important for hypervelocity impacts ...

Things I would try:
pure boron--better tensile strength (and speed of sound) than boron carbide.
UHMWPE--best S/W ratio in the game.
Basalt fiber--also seems to be extremely good vs. lasers, the leading cause of turret death in my game.
What material are you using for Whipple shields? (And just putting all layers outside your main armor?)

Anyone armouring turrets with vanadium-chromium steel?

Anyone armouring turrets with vanadium-chromium steel? Yes, this is my go-to turret armor. It's either this or Tungsten Rhenium in some instances. Won't save the turret from concentrated fire, but will survive the stray bullet impacts. |

You probably want to armor your turrets against lasers first and foremost. If you want both, I think basalt fiber is great at both, at a horrendous price. But really, your best defense against kinetics is distance. Losing a gun or two shouldn't be an issue if you have redundancy.
EDIT: Well, your best defense against kinetics is probably sloped armor. I want custom ship shapes, and maybe weapons that aren't turreted, but still can move. Sorta like a Tank Destroyer gun.

So far, I'm putting silica aerogel exclusively for turret armors. Lasers (and nukes) are a problem much sooner than kinetics are (especially if you're diligent at reducing cross-section). Also, the very light weight of silica aerogel helps to cut mass from reaction wheels.

Even on my pocket battleship I go for silica aerogel. I often have 7 turret on the nose so when I does get hit by something else than a laser its not a big deal. Most of the time it does not happen trough.

Sponsons would be great as well. |
