Don't know about WWII, aka USAAF, but currently all RAF bases, occupied by the USAF are known as RAF xxxx. RAF Mildenhall and RAF Lakenheath are the best known. I believe each has an RAF senior officer on station, also. Last, I was there, they have turned Mildenhall into a prison, for all the security issues, ruined to my mind. Mickey's T-bar for brekkie and the bus to Cambridge or Newmarket; now you have to cab it to Mildenhall village. Bloody shame.
