What does NCC-1701 in Star Trek stand for?
For more information, see MemoryAlpha, the Star Trek Wiki. Whilst there is no official standing on the subject – some example (fan) definitions suggest that the CC initials correspond to “Constellation Class”. Of course this must be purely coincidental since the NCC-1701D was a “Galaxy Class” design! The use of “NC” probably dates back to the first aircraft constructed jointly by the US Navy (N) and the Curtiss (C) Company… and the tradition has endured for nearly a century.
