The in-game weapon specs are already quite informative. There are just a few things that are not covered, which would be helpful:
1) Numeric projectile velocity. For missiles this is listed as fast/slow/etc, which is marginally useful. But for guns it's absent, which makes it hard to determine what is useful for point defense, for example.
2) Turret rotation in degrees/sec. Again, this is sort of there, but unquantified. This would also be useful for missiles.
3) Explosion radius, for anything with a radius, like flak and torpedoes (?).
4) Burst duration for burst weapons (not very important).
5) Weapon HP, if it's different for different weapons (?).
6) Whether it will target/prioritize fighters.
7) Whether it will target/prioritize missiles.
If these were programmatically derived, rather than Strings (which seem to be the case for most fields, given the way burst count, damage, and DPS values are displayed very differently in different mods) then it should be pretty easy to include the exact values.
