C/KC-135 engine question

Hello fellow military enthusiasts,

I normally squat in the civil aviation forum but being a 707 lover I’m beginning to study the military versions of it (717-100 that is) more closely.

Does any of you know if there are still any C-135/KC-135s flying with the old turbojet engines, or have they all been re-engined? If so, when was the last re-engined?

Thanks a lot!

Hans J
