Be that as it may, the workhorse combat aircraft of most NATO air forces and the USAF itself is the F-16, a single-engine fighter, and its nominal replacement, the F-35 is also single engine. You can try to make your point by comparing those vs the numbers of F-15s, F/A-18s, F-Fs, Rafales, Eurofighters and so on in service vs the F-16 and F-35, but bringing C130s and C17s into it is irrelevant, those are not "combat aircraft".

edit: ah but they are "military aircraft", sure. fine.
