Test question; At first glance what is different about this F-15C from the other Eagle pics I have posted recently?
F-15C-32-MC 81-0055 seen here assigned to the 27 TFS, 1 TFW, based at Langley AFB and seen taxiing out for takeoff at Luke AFB at the conclusion of "Longrifle 87" in March 1987.
This was one of the competition judjes aircraft, since this was an air-to-ground exercise [link]
The unusual thing about this F-15C is that it has Conformal Fuel Tanks or CFT's installed. These were not like the F-15E CFT's, as they did not allow bomb carriage, there were only four AIM-7 launchers installed on the tank.
for another view of this same jet. SSDD!
