This F-15A last flew with the 318th FIS. It was transferred to Sheppard AFB to serve as a GF-15A ground instructional airframe. It still has the markings it carried at the Sheppard Technical Training Center.

This was the seventh F-15A built. It was assigned to Edwards AFB from 1973 - 1980. In November 1980 it was assigned to Chanute AFB for use as a ground instructional airframe and redesignated a GF-15A. When the base closed it was transferred to the Octave Chanute Air Museum. The museum closed in 2015 and the a/c was relocated to the Saint Louis Science Center in Saint Louis, Missouri.

This was the seventh F-15A to come off the production line and spent its service life as a testbed at Edwards AFB and then Chanute AFB. It had been on display at the Chanute museum since 1993 and is pictured here being dismantled after the museum's closure, on its way to the Saint Louis Science Center. On 20 July 2022 it was transported to the Combat Air Museum in Topeka, Kansas and on display at that facility. On loan from NMUSAF.
