This aircraft was acquired by the U.S. Air Force in the 1980s and flown by civilian contractors for research projects conducted by the Defense Test and Evaluation Support Agency at Kirtland AFB, Albuquerque, New Mexico. Apparently retired to storage at Davis-Monthan AFB, Arizona around 1990. In July 1992 it was placed on loan to the Pima Air & Space Museum from the National Museum of the United States Air Force.
