Yes, there are big differences between wartime and peacetime operational tempo and maintenance capacity. I flew and managed maintenance for Black Hawks, and while deployed to Afghanistan or Iraq we flew multiples of the hours that we'd fly at home. While deployed, we ran 24-7 maintenance. We had contract maintenance support to probably triple our organic capacity. We had first priority for getting parts, and we had freedom to stockpile parts or do "controlled exchange" (i.e. cannibalize other aircraft for parts) which we couldn't do at home. One outcome is that we effectively wore out the fleet a decade or two faster than planned.
