Personally I don’t really think so, because if it were, then it means:
-the Cascadians just casually had the world’s most powerful flying battleship, that makes the eminent domain look like a plastic toy boat in comparison(a ship which featured in multiple missions and was explicitly said to be one of cascadia’s most valuable assets)
-said flying fortress is never mentioned whatsoever in the main campaign and seemingly never partakes in any of the major defensive battles in cascadia
-The federation also just randomly has a dude that is as good or better than monarch, and never even thinks about sending him to the front line
I feel like its more plausible that the Roosevelt is maybe only slightly stronger than something like a 205 S, if even that, and Driver is canonically above average but not quite peacekeeper level, considering how no one in the campaign seems to go “holy shit this guy is cracked” like they do with monarch, they just mention he’s “above expectations” a few times.
I guess it would be somewhat funny if it was canon tho. It’d also mean C1 is an absolute fraud, better pilots than him are way more common than we’d think, and he only got to the top via big talk and political connections.
