Indeed.

I originally enlisted in the Navy as an Aviation Structural Mechanic (AM), and my first command was an F-14 squadron where I was assigned to airframes. On average, we scheduled 40 man hours for each flight hour (sometimes as high as 60). The F/A-18's that eventually replaced the Tomcats took about half that, but for most aircraft you're looking at 10 MMH/FH, at least, for mx alone.

That said, not all aircraft are created equal, and not all those Tomcats required all 40 scheduled man hours. Maintenance manning, at least in the Navy, is largely determined by man hours. So it isn't uncommon for commands to log as many hours as they can to keep billets, and possibly get a few additional ones. Billets are taken away if you show you can operate at fewer man hours.
