R in the Military Alphabet: Romeo
Code word, pronunciation, history, and how to use it when spelling out loud
In the military alphabet, the letter R is Romeo, pronounced ROW-me-oh. It has been the NATO/ICAO code word for R since March 1956, used anywhere a spelled letter has to survive bad audio — cockpits, ship bridges, dispatch nets, phone lines. Radio operators still answer "Roger" for "received," but when spelling a word, R is Romeo.
Why "Romeo"?
Romeo is the Italian given name Shakespeare fixed in the world's memory with Romeo and Juliet; the name itself descends from a medieval word for a pilgrim to Rome. For ICAO's purposes it ticked every box: recognizable across English, French, and Spanish, three clean syllables with the stress up front, and no likely confusion with any other code word. It stood in the 1951 alphabet and was retained unchanged when the final version took effect in 1956.
R Across Spelling Alphabets
| Alphabet | Word for R |
|---|---|
| NATO/ICAO | Romeo |
| LAPD | Robert |
| Western Union | Roger |
| German (Classic) | Richard |
| German (DIN 5009:2022) | Rostock |
| French | Raoul |
| Spanish | Ramón |
| Italian | Roma |
| Able Baker (WWII, historical) | Roger |
| RAF 1924 (historical) | Robert |
The RAF spelled R as Robert from 1924; the 1943 Able Baker alphabet switched it to Roger, which doubled as the procedure word for "message received." Romeo replaced Roger in 1956, but the proword outlived the code word — crews still say "Roger" today.
Romeo in the Field
In the military time-zone system, Romeo marks UTC-5, the offset of US Eastern Standard Time, so an order timed "1400R" is East Coast winter time. The US Navy hoists the Romeo flag during underway replenishment: at the dip while a ship prepares to come alongside, closed up as the approach begins. And in everyday radio work, Romeo turns up constantly in call signs and tail numbers, read out one code word at a time.
"R as in Romeo" on the Phone
The name is Rivera — R as in Romeo, I, V, E, R as in Romeo, A.

ONE TO REMEMBER
Romeo and Juliett are the only two NATO code words that form a matched pair: the alphabet quietly contains Shakespeare's couple, with Juliett spelled double-T so French speakers don't read a silent final T.
Frequently Asked Questions
What is R in the military alphabet?
R is Romeo in the NATO phonetic alphabet, pronounced ROW-me-oh with the stress on the first syllable. It has been the standard code word for R in military, aviation, and marine radio since 1956.
How do you pronounce Romeo?
The ICAO respelling is ROW-me-oh, three syllables with the stress on ROW. All three syllables are spoken clearly rather than compressed.
Why do pilots say Roger instead of Romeo?
Roger was the code word for R in the WWII Able Baker alphabet, and it was adopted as the procedure word meaning "message received." When Romeo replaced Roger as the letter code in 1956, the proword stayed — so Romeo spells the letter, while Roger acknowledges a transmission.
What time zone is Romeo?
In the military's lettered time-zone system, Romeo is UTC-5 — the same offset as US Eastern Standard Time. A timestamp like 0900R means 9:00 a.m. in that zone.
