Didn't notice those, sorry.
I'm doing the assault shuttle design not because I think it'll be incredibly effective, but because I want to see how well it will work. A box launcher size 40 missile design is what I would use otherwise.
As for your design, it has very good offense, but it will die to any sort of fire that can survive it's attacks, or has a longer range. I've made a fleet of 25% size 12 launcher frigates with a 6000 km/s speed meant to dance in and out of their 250 million km range to keep from being targeted, and they'd slaughter you. No offense. You can easily fit in some defensive measures after all, since they're not too expensive.
Just that I noticed that at most, you can kill 36 ships if you expend all of your ammunition and don't have collies, and the remaining assault shuttles will be able to reach you(if I use like fifty of them in a wave) and if they board the sensor ship, you're doomed. If anything kills the sensor ship, you're doomed. Me too, in a way, but most of my small craft have sensors too that I can deploy.
