The USS Enterprise (NCC-1701-D) was a Federation Galaxy-class explorer that was in service with Starfleet in the mid-24th century. This was the fifth Federation starship to bear the name Enterprise. During her career, the Enterprise served as the Federation flagship.
The Enterprise was built at Utopia Planitia Fleet Yards orbiting Mars in the Sol system. Construction was supervised by Commander Orfil Quinteros. Dr. Leah Brahms was responsible for much of the Enterprise's warp propulsion system design. Some of the Enterprise's components were derived from technology originally developed on the USS Pegasus.
On stardate 40759.5, in the year 2363, the Enterprise was launched from Mars. A year later, on stardate 41025.5, the Enterprise was commissioned.
