what does ncc mean on the starship enterprise
USS Enterprise (NCC-1701) The ship's "NCC-1701" registry number stemmed from "NC" being one of the international aircraft registration codes assigned to the United States; the second "C" was added as Soviet aircraft used "CCCC" and Matt Jeffries combined the two as he believed a venture into space would be a joint operation by the United States and Russia.[10] According to The Making of Star Trek, "NCC" is the Starfleet abbreviation for "Naval Construction Contract", comparable to what the U.S. Navy would call a hull number.[11] The "1701" was chosen to avoid any possible ambiguity; according to Jefferies, the numbers 3, 6, 8, and 9 are "too easily confused".[12] Other sources cite it as a reference to the house across the street from where Roddenberry grew up,[13] while another account gives it as the street address of Linwood Dunn.[14] Jefferies' own sketches provide the explanation that it was his 17th cruiser design with the first serial number of that series: 1701.[15] The Making of Star Trek explains that "USS" should mean "United Space Ship" and that "Enterprise is a member of the Starship Class".[11] The ship's class was officially changed to Constitution Class with the release of the Star Trek Star Fleet Technical Manual in 1975, even though all previous references identify it as Starship Class.[1]
