It's not at all comparable, the Rafale has "on condition" maintenance, there are never factory returns, no major overhaul visits.
Figures are for F-35s which are not in the heavy repair depot. While the Rafale figures take into account all Rafales.
We can measure the difference in the capacity to increase the production of flight hours by the fact that the USAF aims to fly the F-35 for 200 hours per year and does not manage to exceed 150 to 160 hours, while the French Air Force, which flies its 100 Rafales 250 hours per year, sold 12 Rafales to Greece and increased its Rafales to 275 hours per year, then sold 12 to Croatia and plans to increase its Rafale to 300 hours when the sale is effective.
If the Air Force was struggling to produce the flight hours it needs, would it have agreed to resell a quarter of its fleet?
