They had to make sure that each chosen word sounded different to the others, and was easily pronounceable by speakers of all the European languages, not just in English. It is called the "NATO" alphabet because it was standardised by the NATO member countries back in the 1950s to allow accurate exchange of radio messages between air, naval and army forces of all the NATO member nations. Numbers are pronounced as normal, except often 9 is pronounced " Niner" so it doesn't get confused with 5. The standard "NATO" phonetic alphabet (actually the International Radio-Telephony Spelling Alphabet) is:Īlfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. The "NATO" / ICAO / ITU Phonetic Alphabet / Army Alphabet / Police Alphabet Using the phonetic alphabet to spell out names, locations and so on makes accurately understanding messages a lot easier, because many letters can be easily confused when heard over a crackly radio link (B, C, D, P, T and M, N and F, S, etc). The International Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, NATO spelling alphabet, ICAO phonetic alphabet or ICAO. The international radiotelephony spelling alphabet registration#When you are spelling out a name, location, code, registration number, postcode etc, over a noisy or faint radio or phone link, it is easy for letters and numbers to be misheard. Nevertheless, a NATO unclassified version of the document is provided to foreign, even hostile, militaries, even though they are not allowed to make it publicly available.Standard Phonetic Alphabets Used For Radio & Telephone Using Phonetic Alphabets Helps Convey Information Accurately Over Walkie-Talkie Radio However, ATP-1 is marked NATO Confidential (or the lower NATO Restricted) so it is not publicly available. 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. The international radiotelephony spelling alphabet code#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 voice its “phonetic alphabet”. 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. NATO uses the normal English numeric words (Zero, One, with some alternative pronunciations), whereas the IMO uses compound numeric words (Nadazero, Unaone). The same alphabetic code words are used by all agencies, but each agency chooses one of two different sets of numeric code words. It is a subset of the much older International Code of Signals (INTERCO), which originally included visual signals by flags or flashing light, sound signals by whistle, siren, foghorn, or bell, as well as one, two, or three letter codes for many phrases. It is used by many national and international organizations, including the International Civil Aviation Organization (ICAO), the International Telecommunication Union (ITU), the International Maritime Organization (IMO), the North Atlantic Treaty Organisation (NATO), the Federal Aviation Administration (FAA), and the American National Standards Institute (ANSI). The paramount reason is to ensure intelligibility of voice signals over radio links. Instead, the NATO alphabet assigns code words to the letters of the English alphabet acrophonically so that critical combinations of letters (and numbers) can be pronounced and understood by those who transmit and receive voice messages by radio or telephone regardless of their native language, especially when the safety of navigation or persons is essential. Though often called “phonetic alphabets”, spelling alphabets have no connection to phonetic transcription systems like the International Phonetic Alphabet. The NATO phonetic alphabet, more formally the international radiotelephony spelling alphabet, is the most widely used spelling alphabet.
