These are all great. Top work. Love the subtle organic divergences from vanilla style while still looking like they really belong in the 3 design types.
In terms of balance I think the biggest outlier right now is the Burn Reload Driver. It just gives far too much missile sustain on all 3 ships its on. Potentially getting 4 (with expanded racks) or even 6 (with racks and missile skill) Reapers or Hammers from ammo regen between the 2 frontal larges on the Skullbasher every 20 seconds or so is just too much, and on the Fossil getting at least 3 sabots back every burn is exceptionally powerful. Especially since all the ships its on have all that low tech peak performance time to keep up the regeneration. If it had a limit, maybe it can only regen ammo on the first 10 burns in a battle so its still giving potentially 50% total ammo back (like a half effectiveness missile autoforge), it might be much more agreeable. It could also do with a more precise system description explaining the 5% regen each burn with some rounding (like 12 total ammo missiles getting regen but 10 total ammo not getting regen). And if I may, I think a better name for the system could be 'Forge Drive', as its like a combination of Autoforge and Burn Drive.
Catapulting Jets probably gives its +75 speed boost for too long as well, there's only about 3-4 seconds of downtime between the speed boost ending and being able to catapult again.
Given the similarity of the Pegasus to the Fury, and given how the Fury is very strong in this version, it may be slightly undervalued at 24 DP what with its more hefty weapons complement. This one is more vague I think, and since the Fury isn't being nerfed from 15 DP to 20 until next update it may need to stay at 24 for now in order to be competitive.
Abstruseness may also be very slightly DP undervalued. Or, since its similar to the Heron with lower speed, worse system, but with a free Xyphos on top, it may be very slightly overvalued. But I think it sits comfortably in the 25-30 range.
