This chart shows the incredible cost of operating the US Air Force's most expensive planes

The US Air Force's unquestioned aerial dominance does not come cheap. For its 10 most expensive planes, operating costs per hour start at $58,059, and it only climbs from there. The following graphic, based upon the Air Force's cost per hour of flight estimations, lists the 10 most expensive planes to operate in descending order:

The E-4 Nightwatch is the most expensive military plane the Air Force operates. The Nightwatch is a command and control aircraft that's meant to serve as a flying airbase for the US president and cabinet members in case of a national disaster. Designed as a doomsday plane, the Nightwatch is expensive to operate because of its size and technical abilities. The plane is specially designed to survive electromagnetic pulses, with additional thermal and nuclear shielding. It can also refuel aerially and fit up to 112 passengers.

Surprisingly, the much maligned F-35 is only the seventh most expensive plane per hour that the Air Force flies. Its costs are partially due to the lack of an efficient supply chain for the aircraft, something that should be sorted out over the coming years. Among the cheapest aircraft that the Air Force operates are Predator drones and the A-10. These aircraft cost an estimated $1,500 and $11,500 per hour to operate, respectively.

NOW WATCH: This is why US aircraft carriers are a force to be reckoned with
