Wrathmonk - Good point but RCS would be only part of the equation in the successful detection, identification, tracking and prosecution of JSF; many other factors would come into play, some quite sneaky. Moreover, if any conceivable OPFOR manages to acquire radar matching Sampson's sophisticated capability to target multiple supersonic cricket ball-sized objects simultanously, let's hope they don't also have PAAMS' other bells & whistles, nor highly trained, well-led operators, e.g. personnel able to filter and isolate threats like Silkworm missiles out of all the other clutter and not misidentify and shoot down non-threatening objects like airliners (or even cricket balls).
