....as those applied to the Backfire and Fencer? I know of
anti-radiation white applied to the underside of nuclear bombers, but
the reason of white leading edges on the Su-24 escaps me - seems
'anti'camouflage. Perhaps it helps in disguising the shape of the
'incoming' from visible/IR sensors on the ground? Thanks in advance
for any explanation.
