;F-15 Streak Eagle (AF Ser. No.72-0119)
:An unpainted F-15A stripped of most avionics demonstrated the fighter's acceleration capabilities. The aircraft broke eight time-to-climb world records between 16 January and 1 February 1975 at [[Grand Forks AFB]], ND. It was delivered to the [[National Museum of the United States Air Force]] in December 1980. The aircraft is currently on display in the museum's Research and Development Hangar.<ref>{{Cite web |title=McDonnell Douglas F-15 Streak Eagle |work=National Museum of the United States Air Force™ |url=https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact-Sheets/Display/Article/197972/mcdonnell-douglas-f-15-streak-eagle/ |url-status=live |archive-url=https://web.archive.org/web/20190813231328/https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact-Sheets/Display/Article/197972/mcdonnell-douglas-f-15-streak-eagle/ |archive-date=13 August 2019 |access-date=13 August 2019}}</ref>
