This is a model of unknown scale of the U.S. Air Force Titan II intercontinental ballistic missile deployed from 1962-1987. A two-stage, liquid-fuel missile, it carried a nuclear warhead and had a range of approximately 5,500 nautical miles. Because it was both stored in and fired from underground silos, the Titan II was much less vulnerable to destruction in an attack than its predecessor, the Titan I. John and Cynthia Heyde donated this model to NASM in the late 1980s.
This object is on display in Rockets & Missiles at the Steven F. Udvar-Hazy Center in Chantilly, VA.
