Being an avionics tech for the Air Force currently working on F-15E's, I'm fairly certain that E models use the APG-70 exclusively (at least all the ones here do). I know there are/were plans to upgrade some of them to the newer AESA packages, but to my knowledge it hasn't happened yet outside of testing due to costs. For 15's the APG-63(V)1, 2 and 3 have only been put on the C models. A stationary antenna would make my job a lot easier, removes a lot of the wear and tear on the system when you don't have to worry about hydraulic lines bouncing around during flight, and especially on landings since 'hard' landings can really jack up the antenna.
http://www.f-15e.info/joomla/en/technology/avionics/65-radar-system does a good job explaining a lot of it, though there is some (as of today) incorrect information. Obviously I can't point out what's wrong, but it's close enough. I'd love to post everything I have access to in forms of tech manuals and training guides, but it just ain't legal.
http://sobchak.files.wordpress.com/2009/06/f15e.gif is a good source for pure cosmetics of both internal and external features. http://en.wikipedia.org/wiki/APG-63 as well due to the sole picture on the page.
One thing I'd really love to see modeled properly because it's just such a cool system would be JHMCS, along with the Sniper pod. The latter of which would be nigh impossible since it's still a fairly new piece of technology, along with being highly classified of course.
