The real fun will come in when different hull parts have different armor ratings and you can apply different materials to them, like building one part out of steel or another out of titanium. That would allow us to build some very literal shield walls.
Also that capital bridge section is massive. Are you quite certain that when you get into the higher part number and size, it won't drag on computers? Just looking at the different sizes between bridges, I can imagine a capital ship being massive and sporting some planetkiller type weapons. And then of course, space stations should be fun.
