what does ncc in star trek stand for
USS Enterprise (NCC-1701) The ship's NCC-1701 registry stems from NC being one of the international aircraft registration codes assigned to the United States. The second C was added because Soviet aircraft used Cs, and Jeffries believed a venture into space would be a joint operation by the United States and Russia.[16][17] NCC is the Starfleet abbreviation for "Naval Construction Contract", comparable to what the U.S. Navy would call a hull number.[18] Jeffries rejected 3, 6, 8, and 9 as "too easily confused" on screen;[17] he eventually reasoned the Enterprise was the first vessel of Starfleet's 17th starship design, hence 1701.[19] The Making of Star Trek explains that USS means "United Space Ship" and that "Enterprise is a member of the Starship Class".[18] The ship was changed to Constitution class with the release of Franz Joseph's Star Fleet Technical Manual in 1975.
