The Air Force wants to replace the A-10 ($10,000/hr) with the F-35 ($30,000/hr), to save money. Not sure if they worked the $80,000,000 unit cost in to the F-35 hourly rate.
Manned aircraft are great in technologically asymmetrical warfare, but in a matched all out contest, they lose to robots 100%. They should make do with the manned aircraft they have, and replace them with drones, etc, as needed.
I would imagine our drone capabilities are growing exponentially.
