Then again, if the Navy is the ‘preferred’ service for long term missions, why does the USAF run the X-37 long term missions?

The Clementine badge - there are a couple of youtube videos exploring the various design parts of the patch and possible meanings and oblique references. (One of them deals with a blurred out section of one image - interesting).

I suspect because the X-37 is unmanned. The relevant Navy experience doesn't apply.
