: The COS does seem to run up against the size issue of sci-fi that plagues
: things like the Death Star, in that they don't seem possible, let alone
: feasible. The Long Night of Solace is essentially the volume of 148
: already-massive CAS assault carriers, and unlike the Infinity I don't see
: where one giant ship would actually be more effective at the covenant's
: mission than that many smaller ships (and unlike the Long Night of Solace
: the Infinity is basically only larger than most large UNSC ships by a
: factor of three to five.)

: Then there's the question of how you marshall the resources to build
: something like this. The amount of resources involved in making a super
: carrier is essentially that of strip-mining entire moons. But even if you
: get the thing built, how are you going to staff it and fuel it? A
: Nimitz-class aircraft carrier costs around 8.5 billion dollars, and it
: costs roughly a quarter of that cost to substantially refurbish one,
: including refueling its nuclear reactor. I can only imagine when we get
: into ships of that size, especially ones that are designed to be a nucleus
: of the entire fleet, that costs skyrocket vastly, and I don't think
: Engineers could solve that problem. We see in the post-Covenant world that
: it's difficult for anything other than larger Covenant splinter factions
: to be able to field a CAS, which makes me wonder how the Covenant could
: have run it even at full strength, let alone multiples of them.

As Vagueness said it's so big it's silly, and completely impractical.
