We've already discussed this, it's not Heresy Era, I've said this a number of Times. Also, as you said before, size, in the Warhammer Universe is debatable, as things are constantly being changed. Lexicanum (My go to source for Warhammer knowledge) said that (the same cannons mounted on a ) If so, then a Thunderhawk would have to be pretty fucking huge to carry a generator capable of powering it up a weapon of that magnitude, without losing it's flight capability.And as for the ship... Well, after looking into it, apparently things have got pretty fucked up as far as size goes, apparently, now, the smallest Capital ship that the Imperium fields is the Cobra-class Escort Frigate at 1.5KM. unfortunately, that thing has little to no space for an assault force, built like Defiant from DS9. Plus, of course, dat look... Vengeance is an awesome shape for a ship.Fuck it, Let's say that the Vengeance is 2.5KM and have done with it, Who's gonna complain? Matt Ward? He can blow me.

I have no idea what is going on as I am out of the loop of W40k. However if you are desizing it don't you need to modify troop numbers/weapon placements etc to compensate? Downsize the ship downsize what it has?
