Germany has both the F-4F and MiG-21MF with AIM-9J and R-60s respectively. (As well as also the F-4F Early if you want to count that).
Italy was given the AIM-9J for its F-104G and 104S based on the fact Turkey and several other nearby European nations did so on their F-104G and S's without modification. Factoring in that without this, Italy would be without any top tier aircraft for some time, it was done for game balance using those grounded factors.
The German F-104G is however not in such a balance situation and not in need of them currently. With Germany already having 2 other (Or 3 for some) top missile jets.
