International Signal Code Flags

The alphabet's common name (NATO phonetic alphabet) arose because it appears in Allied Tactical Publication ATP-1, Volume II: Allied Maritime Signal and Maneuvering Book used by all allied navies in NATO, which adopted a modified form of the International Code of Signals. Because the latter allows messages to be spelled via flags or Morse code, it naturally called the code words used to spell out messages by its "phonetic alphabet". The name NATO phonetic alphabet became widespread because the signals used to facilitate the naval communications and tactics of the United States and NATO have become global. However, ATP-1 is marked NATO Confidential (or the lower NATO Restricted) so it is not publicly available. Nevertheless, a NATO unclassified version of the document is provided to foreign, even hostile, military's, even though they are not allowed to make it publicly available. The phonetic alphabet is now also defined in other unclassified international military documents. Source:
