It shows that C-17 cost 1/3 to operate compared to C-5 and almost on par with C-130.
These numbers are just stunning, showing how efficient the C-17 to operate compared to other aircrafts. It's operating cost only about 20% higher than the C-130J while having 2 times the lift capability and faster speed.
I think those figures and the associated graphs are a little simplistic, not taking into account the different missions etc.
C-17 tend to fly longer missions than C-130 so some of the costs, ground crew, infrastructure etc are similar but the C-17 in some ways uses less of those.
C-130 may use X ground crew, Y facilities /mission, Z fuel/hr
C-17 may use ?xX ground crew, ?xY facilities/mission. ?xZ fuel/hr
Depending on the ratios in the above criteria it is plausible that given the longer mission profiles of the C-17 that the statisticians would get those results.
Not agreeing they reflect the real world, just seeing it like an accountant.
The Guam B2 crash putting up the hourly cost of running the fleet, it didn't really, just a beancounters view of the world.
Sure one has to take these things into account but the loss of one frame did not suddenly almost double the cost of a strike mision.

These numbers are cost per flight hour.
One way to very easily almost double the hourly cost is to cut the flight hours in half.
If we saw the average annual number of flight hours per type, then we would be less confused.
These are military planes, not commercial planes designed and made to earn money. In the perfect world they would sit in a hangar all day while the crews would party in the officers' club. The "operating costs" would be ten bucks for a monthly vacuum cleaning of the cockpit. With zero flight hours that would make the hourly cost infinite.
With the wars going on these days especially the C-17 is flying many hours. That reduces the hourly cost. End those wars, and the C-17 hourly cost will skyrocket.
Always keep your number of landings equal to your number of take-offs, Preben Norholm
