Around the time of Desert Shield/Storm, the only active USAF
units flying the F-4 were the 35th TFW at George AFB, the 52nd TFW in Germany, and the 3rd TFW at Clark AB
in the Philippines. It was the George unit that got all the Phantom glory during that time, but it wasn't the only batch of guys flying the types as the 3rd had dets in Turkey during that time.

As Desert Storm arose, the 90th Fighter Squadron (based at Clark AB
after Vietnam) sent six F-4's to Incirlik Air Base, Turkey. The squadron's involvement in Desert Storm gave the 90th the distinction of being the oldest squadron in Pacific Air Force to participate in all five wars. The squadron joined 11th Air Force in 1991 and moved to Elmendorf AFB, AK
. The squadron replaced its F-4's for McDonnell-Douglas F-15E Strike Eagles.
