I'd ask just which ships you are looking at?

The Codex ships aren't exactly consistent with things and that is especially true for naming things as there are plenty of "concussion missiles" on ships that conform to LIGHT CM stats and then you have the 8d10x2 damage instead of 9d10x2.

If the "Super Heavy Missiles" are the 11d10x5 ones they do have a heavy missile launcher in Starships of the Galaxy.  No idea about the "heavy proton torpedoes" although I've considered a version that deals 4d10x5 but has the -20 attack against smaller ships.

The Acclamator II's "heavy proton torpedoes" just look like "Heavy CONCUSSION MISSILES" in much the same way the medium concussion missiles look like proton torpedoes.  Most likely I'd just say they are misnamed/refluffed missiles and treat them as such.

The "Super heavy" Concussion missiles dealing 11d10x5 instead of the normal 9d10x5 for the heavies could be an error they never bothered to correct (figure KotOR and SotG plus some of the other early books were all being worked on at the same time and the left hand didn't always know what the right was doing) but if keeping the 11d10x5 I'd likely be treating things as a refluff of a fire-linked (4) heavy missile system regarding prices and EP requirements.  Either that or the take it out and add a Proton torpedo launcher for more damage but taking up even less space.

And yes I have noticed that the damage stats on ships seem to be off, though it seems that some include fire-linked bonuses, and there's a ship with Heavy Concussion Missiles that has the damage and capacity for medium concussion missiles.

If the "optional firelink" isn't installed then maybe the listed damage would reflect that although it then confuses ammunition when each "shot" needs multiple missiles.  The naming of missile systems is just obscene and I think it's even worse when people go and use that as an excuse to abuse the modification rules.  You wouldn't believe how often I've seen someone say they're going to start with the A-Wing and then Strip off the "Medium Concussion Missile Launcher" for 5EP but then install a light concussion missile launcher for3EP netting them 2 EP in the process but not altering the ships stats one bit otherwise.
