Tranquility Base was a Federation shipyard located near the Sea of Tranquility area of Luna. Among the many Starfleet vessels to be constructed at the yards was the Constitution-class starships USS Defiant and USS Excalibur. (ST reference: Star Charts, ENT episode: "In a Mirror, Darkly", ST reference: Ships of the Line)
- The Starfleet facility is presumably an expansion of the landing site of Apollo 11.
