This TF-15A a/c was later redesignated a F-15B. In 1976 this TF-15A was used by McDonnell Douglas for a world wide sales tour, including this visit to Japan. For the tour it was painted in U.S. Bicentennial markings. Later in its career it became the prototype for the F-15E Strike Eagle program. It eventually ended up in Saudi Arabia as an instructional airframe. It currently is located at the RSAF Museum in Riyadh.
