...is still flying around the Nellis Range Complex years after its official retirement back in 2008.
...we know that at least one, and reportedly up to six F-117s are still flying,...
...could theoretically be used as something of a flying measuring stick for evaluating a radar systems ability to detect and track low-observable flying objects, or conversely, it could be used as a surrogate to test new radar absorbent materials and coatings applied to its flat, facet like structure that was built originally to accept such applications.
...program managers could have a control variable, in this case the F-117′s well documented radar cross-section and its infra-red and visual signature, and an independent variable for which to test upon, that independent variable being a new radar absorbent material or other experimental signature control component. By doing so testers can leverage highly accurate real-life metrics for which to judge the effectiveness of their new application and then either ditch it or improve upon it, with the goal of eventually migrating it to operational weapon systems.
...it would make total sense for the USAF to field the F-117s as stealth aggressors against American and even friendly foreign platforms and aircrews during military exercises.
