Military Phonetic Alphabet

"Military phonetic alphabet", "NATO alphabet" and "ICAO alphabet" are three names for the exact same list of 26 code words, there is no separate, secret military-only version. The naming confusion is purely historical.

Where the naming confusion comes from

Before 1956, the US and UK armed forces each used phonetic alphabets that differed from one another and from today's, the best known, used throughout World War II, started with "Able, Baker, Charlie, Dog, Easy, Fox..." (the 1941 Joint Army/Navy Phonetic Alphabet). That history is why the current alphabet is still popularly called the "military alphabet", even though it was replaced seven decades ago by a civilian, internationally standardized ICAO version.
The 1956 version (Alfa, Bravo, Charlie...) was adopted by ICAO as the single standard for all of world civil aviation, and NATO forces simply switched to using that same standard instead of keeping a separate code, which is why the "NATO alphabet" nickname stuck harder in popular use than "ICAO alphabet". Today the very same alphabet, with zero variation, is used by militaries across every NATO country, civilian pilots and air traffic controllers, merchant shipping (via the ITU), police forces and call centers, there is no separate "more official" version reserved for military use.

Examples

Spelling the acronym itself

Input: NATO
Expected output: November Alfa Tango Oscar

The organization's own acronym, spelled with the very alphabet that bears its name.

A common military code

Input: SWAT
Expected output: Sierra Whiskey Alfa Tango

The same table used by police and military forces, there is no separate version.

Full tool FAQ

Why are the letters A and J spelled "Alfa" and "Juliett", not "Alpha" and "Juliet"?

Those are deliberate, official ICAO spellings. "Alfa" uses an "f" instead of "ph" so speakers of languages without that convention still pronounce it correctly, and "Juliett" gets a second "t" because, in French, a single trailing "t" tends to go silent. They aren't typos, reverting them to "Alpha"/"Juliet" would defeat the alphabet's whole purpose.

Where did the NATO phonetic alphabet come from, and why does it exist?

Why are some numbers pronounced differently over the radio (Tree, Fower, Fife, Niner)?

Is the phonetic alphabet only used by the military?

How do I spell my name or a code using the phonetic alphabet?

Frequently asked questions

Is there a difference between the "military alphabet" and the "NATO alphabet"?

No. They are different popular names for the same alphabet, standardized by ICAO in 1956 and used unchanged by the military, civil aviation and other sectors.

What alphabet did the military use before this one?

In the US and UK, the one most used during World War II began with "Able, Baker, Charlie, Dog, Easy, Fox...", it was replaced by the current ICAO standard in 1956 specifically to unify international communication.

Do all branches of the armed forces use the same alphabet today?

Yes. Army, navy, air force and other branches across NATO countries use the same list of 26 code words, there are no variations by branch or by country.
