The 7 E-3 AWACS planes operated by the Royal Air Force as the Sentry
AEW1 have CFM-56s 2A2s, the E-3 being based on a 707 airframe rather
than 717/KC135 types.  Also CFM powered are the five KE-3As operated by
the Royal Saudi Air Force (used as tankers rather than surveillance
aircraft) and presumably (no pictures or other data other than
construction numbers to hand) also the 4 E-3As operated by France. The
18 operated by NATO would appear to be TF33 powered, but these are
older, being built between 1981-84, as opposed to 1989-90 for the RAF
ones. USAF AWACS planes, including E3-Bs, were all built before even the
NATO planes, so all are (AFAIK) TF33 powered.

I also have a picture of a US Navy E-6A with CFCM-56s - these were built
new, but many of the E-8s were built using old civilian 707-300
airframes, so have JT3D/TF33 engines.
