: It's funny because the largest ship in Halo, which is so much larger that
: it's borderline comical, is just about the size of a super star
: destroyer(19km). Which was used as capital ships and about a dozen were
: fielded all over the empire, which meant it was used in a similar manner
: to the covenant CAS assault carrier. In comparison, the CAS measured only
: 5000m long, so that should give you an idea of the scale comparison
: between Halo and Star Wars. The CSO supercarrier was only seen once and
: apparently were almost exclusively used as capital ships by Hierarchs, so
: if anything it's more like the Death Star(absurd scale, price, and
: destructive potential) than an actual ship.

Well, the largest "normal" ship in Halo. The Forerunner stuff starts getting real huge too, but especially since those are apparently far more automated than your average human or Covenant ship, as well as the fact that their tech is still out of reach for us mere mortals, makes it more forgivable. The only forerunner construct that starts getting really ridiculous is probably Trevelyan (large enough that it swallowed up its sun and planets when it came back to real space!) but things like Mantle's Approach are still huge (300-ish kilometers on its longest axis.)
