USN AVIATION assets. Not naval assets. It should be clear from context but still, what a typo!
And yes, that IS a straight comparison of airframes, training and munitions, it's more or less meaningless in terms of any strategic calculations, but it's a useful metric on the relative strength of the militaries. Obviously comparing mobile aircraft carriers (which can be concentrated and strongly defended by ships, but limited in fuel, take of weight and other compromises made for sea-borne aviation) and fixed air bases (fixed, vulnerable, spread out, but on the other hand can be heavily hardened, with optimal sortie rates and a much higher fuel and ammo capacity) spread across China has no real direct applicability.
