J in the Military Alphabet: Juliett
Code word, pronunciation, history, and how to use it when spelling out loud
In the military alphabet, the letter J is Juliett, pronounced JEW-lee-ett. Note the spelling: ICAO writes it with a double T, not like the English name Juliet, so that French speakers do not read the ending as a silent letter. Juliett has been the code word for J since the 1956 NATO alphabet, having first appeared in ICAO's 1951 list.
The official ICAO spelling is Juliett with a double T — added so French speakers, who might otherwise treat a single final T as silent, will pronounce it.
Why "Juliett"?
Juliett comes from the given name — the same one Shakespeare gave Romeo's counterpart, which means the alphabet quietly contains both halves of the pair, since R is Romeo. Names familiar across many languages made strong candidates under the selection criteria ICAO applied, and Juliet is recognized nearly everywhere. The double-T spelling was a deliberate concession to French, one of ICAO's working languages: "Juliett" forces the final T to be pronounced where "Juliet" would invite a silent ending.

Juliett in the Field
In the military time zone system, each zone carries a letter of the alphabet — and J is the odd one out. "Juliett time" has no fixed offset; it means the observer's local time, while Zulu means UTC. The word also served as a NATO reporting name: the Soviet Project 651 cruise-missile boats were known in the West as the Juliett class. One place you will not find it is US Army and Marine company lettering, which traditionally skips J — a habit dating to the era of handwritten rosters, when I and J were too easy to confuse.

Frequently Asked Questions
What is J in the military alphabet?
J is Juliett, pronounced JEW-lee-ett. It is the tenth code word of the NATO/ICAO phonetic alphabet, and the official spelling uses a double T.
How do you pronounce Juliett?
The ICAO pronunciation is JEW-lee-ett — three syllables, ending in a clearly sounded T. The double-T spelling exists precisely to make sure that final T is spoken.
What was J before it was Juliett?
The RAF's 1924 alphabet used "Johnnie," and the WWII US-UK Able Baker alphabet used "Jig." Juliett took over with the NATO alphabet adopted in March 1956.
Why is Juliett spelled with two Ts?
French was one of ICAO's working languages, and in French a single final T after a vowel is normally silent. Doubling the T signals to French speakers that the letter must be pronounced, so the word sounds the same in every cockpit.
