Star Trek Enterprise D Key Chain U.S.S. Enterprise NCC-1701-D Quantum Mechanix Now you can travel with the Federation's 24th century flagship: the U.S.S. Enterprise NCC-1701-D. QMX has taken the sixth starship to be named Enterprise and created a sleek screen-accurate replica in a zinc-steel alloy with a pewter finish. The ship's hefty saucer and proportionally smaller warp nacelles reflect the greater efficiency of the engines compared to the original Enterprise.
