So, I just got done doing a whole lot of design work with the Lithium propellants that can be found in this thread (credit to Rocket Witch for getting the ball rolling, and someusername6 for figuring out a number of the more complicated bit's of getting Lithium Hydride to work). This is what I came up with. Just a heads-up, it's an imgur album, mostly because I don't feel like fumbling around looking for the spoiler button. Lithium Hydride is OP, Please Don't Nerf

<snip> I don't have a name for it yet, and I'm still min-maxing certain modules, but overall I'm quite happy with the result. This ship started out as a modification of the stock corvette and will feature in an upcoming custom campaign I've been working on. It's main armament is thirteen 37.4 km/s Amorphous Carbon coilguns and two (one on each side) 57.4 km/s coilguns. It also has ten 9.4 km/s point defense railguns. Effective range for the coilguns is well over 1000 km though for now engagement range is limited to around ~250-300 kilometres for stock ships. The ship uses hydrogen deuteride (64 tanks total, including the drop tanks). Long range propulsion is provided by a 83.7 km/s 750 MW MPD thruster giving it up 97 km/s deltaV. The NTRs give it 10.5 km/s delta V and a burn time of 1 minute and 39 seconds (almost 6 Gs of acceleration). It also has three directional resistojets. It doesn't have proper armour as I didn't want to add more layers on top of the decorative layers. But if it did it would use a silver/tin/osmium/fibre/aerogel composite. Right now it's only protection is redundancy: 5 reactors, 6 main thrusters, 9 crew modules, 14 main radiators and the 60 internal fuel tanks. The guns are armoured with over 2 centimeters of basalt fibre. Yup, hands down the best looking ship to date. A labor of love for sure.

So I was testing something yet again. We all know that making drone as small as possible make them super deadly to big ship due to big cross-section. But I recently decided to look into a fun option back again. The fun option of using big ass gun and strap them to big drone. I quit doing this before because I was going in from the wrong perspective. Instead of just making a big gun that shoot big projectile, I should have made a gun that shoot big payload. Which I first tried to experiment with a 50g flak conventional cannon, but unfortunately the projectile was too light to be effective. So I make another version that is much bigger, one that fire 300g flak payload. Which result in this. In less than ten confirmed hits, the ship went from pristine to glowing swiss cheese, ripping everything within and it's all thanks to this custom payload. One thing I discovered about flak is that if you keep fragment weight more than 1 gram, they tends to rip things apart way more effective. That and using multiple of them together always seem to render more fragments at the same time. The drone has nothing special about it. It weighs almost a ton, with decent delta-v and anti-laser armor. But it was the perfect platform to launch flak rounds at the target. I'm going to experiment with slightly smaller version like for example, 100g conventional cannon round or 200g.

Quick question, what do you people use for lightweight anti-laser armor?

Quick question, what do you people use for lightweight anti-laser armor? Aramid Fiber (for low ablation rate, costs about 300c/kg) Nitrile Rubber (for cost effectiveness, ablates twice as fast as Aramid) Thats for single layers, I'm fairly confident there's a carbon heatsink you can use if you connect it to the rubber layer.

jasonvance They said Silica Aerogel ablates as fast as other materials. Is that true?

I use silica gel, you can never go wrong with more silica gel because I'm too lazy to use other stuff.

Just that it's not as good as before, so you need to use centimeters of it for decent protection instead of 500 micrometers of it. Compared to aramid fiber composite armor, it's better and way less complicated. And thanks to its slow ablativeness, it's the best thing against gigawatt laser since everything else will get cut down in seconds while it will lasts more than that. EDIT: Also great, I just found out that flak can explode without a remote control, but a nuclear bomb can't. There goes the mini nuke cannon.

jasonvance They said Silica Aerogel ablates as fast as other materials. Is that true? Short answer: no If you ignore the density on it, yeah SA gets eaten through at a fairly high amount of cm/s. But if you take into account the low density it is still an okay anti-laser material, and has some uses for super light weight somewhat laser resistant armor. It does not share the same burn through rate as say graphite aerogel (the other low density contender). It gets heavily beat by aramid fiber in laser defense and beat by rubber in cost effectiveness, but if you need something light weight that will survive a scratch its still worth while. 100cm Silica aerogel will hold off a single high intensity laser for ~50 seconds 100cm Graphite aerogel will hold off a single high intensity laser for ~3 seconds 10 meters of graphite aerogel will hold off a single high intensity laser for ~20 seconds (this is the mass equivalent of 100cm silica aerogel)
