From the early 1970's, the German Air Force has trained F-4 pilots in the United States through a contract program with the USAF.  This was performed by the 35th Tactical Fighter Wing  at George AFB until 1992 when it was moved to Holloman AFB and placed within the 49th TFW (later simply 49th Fighter Wing).  The German pilots are assigned to the German Air Force Flying Training Center with the actual flying performed by the 20th FS, though for a short time in the early 1990s the 9th FS was also equipped with F-4s.  Most aircraft used are F-4Fs, however the GAF has also contracted the use of F-4Es and owns several very late model F-4Es (serials 75-0628 to 75-0637).
