If you can operate a jet fighter-bomber for less than (say) $200 K an hour* I'd be very surprised. And that doesn't take into account the servicing time on modern 'hangar queens' to get them ready for their next sortie. And what's the cost per hour of operating a carrier??

Try to include ALL your costs in working out the cost-efficiency.

* Let's be really generous and say you get 10,000 hours of service life out of a fighter jet. (The designed service life is only 8,000 hours.) The F-35 costs around 130 million bucks so over 10,000 hours that cost comes out to $13,000 per hour in just amortising the purchase cost, without adding in the operating costs themselves.
