The Titan II was an American Human-rated expendable rocket that was in service with NASA and the United States Air Force in the mid-20th century. The rocket was used for national defense and space exploration.
Titan II rockets were later used in the mid-21st century, during World War III, as a type of nuclear missile.
One of this type of rocket formed the framework and launch vehicle for Zefram Cochrane's experimental warp ship, the Phoenix. (Star Trek: First Contact)
During the 23rd century, a photo of a Titan II rocket hung on a corridor wall just outside the base commander's office at Starbase 11 in 2267. (TOS: "Court Martial")
The photo appearing in "Court Martial" depicted the Project Gemini capsule on a Titan II rocket. It was one of many photos taken in 1965 and 1966 for public use by NASA.
