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.
In 2024, in a gala held for the Europa Mission astronauts, an illustrated depiction of this rocket was seen on the display "Manned Space Flight 1961-2024". (PIC: "Two of One")
Titan II rockets were later used in the mid-21st century, during World War III, as a type of nuclear missile.
One rocket of this type 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")
