The Zefram Cochrane Space Flight Center was a Starfleet research and flight test facility in northern California in the mid-22nd century. This center included a mission control and a sled-based launch facility. The facility had hangars for prototype craft, such as the NX-Beta.
In the 2140s, when the NX Project was based at this facility, Jonathan Archer and A.G. Robinson were assigned to this center as test pilots. Charles Tucker III was assigned here, as well, as a member of the center's engineering staff. (ENT: "First Flight")
