A Centaur G-Prime was on display at the U.S. Space & Rocket Center in Huntsville, Alabama, for many years. In 2016, the center decided to move it to make way for a redesigned outdoor display, and it was transferred to NASA's Glenn Research Center (as the Lewis Research Center had been renamed on 1 March 1999). It was officially placed on outdoor display on 6 May 2016 after a ceremony attended by forty retired NASA and contractor staff who had worked on the rocket thirty years before, and by officials including Glenn Director Janet Kavandi, former Glenn Director Lawrence J. Ross, and the USAF's former Titan IV mission manager, Colonel Elena Oberg.
