As I recall from AW&ST of the time, the pylons from the 707-700 flight
test aircraft were turned over to the KC-135R project. But I don't
know of any military 707's with CFM56's; were/are there any? Perhaps
our friends at Boeing would know...

Anyway, I think of the E-8 JSTARS aircraft as the latest and best
military 707, but it seems to wear old low-bypass turbofans (see
<> for an in-flight photo). My guess
is that 707's are so rare in the U.S. military compared to KC-135's
that it wasn't worth the trouble to upgrade them.
