Does anyone have a list of the KC-135 that have been upgraded with advanced surveillance capability? I used to have that list but can't find it. Btw, if I remember correctly, the KC-10 also has advanced surveillance capability that can be enhanced with a module that hooks into the avionics system.

Edit: the KC-135s that I'm thinking of were the 4 "Rivit Quick" birds. It looks like they have been retired.
