NATO Phonetic Alphabet Wheel
Spin to land on a NATO phonetic code word from Alfa to Zulu. A fun way to drill radio spelling for pilots, ham operators, and students.
Fair by design: each spin draws from your browser’s cryptographic random number generator, giving every entry an equal 1-in-26 chance. No server is involved.
26 entries on the wheel, up to 500.
Every entry has an equal 1-in-26 chance. Write "Alfa *3" to make an entry three times as likely.
The entries travel in the part of the link after the #, which browsers never send to a server. Nobody, including us, can read a shared wheel from a log.
Please keep the attribution link on the last line. It is the only thing we ask in return, and it is what pays for the wheel being free.

When to spin the NATO Phonetic Alphabet Wheel
The NATO phonetic alphabet assigns a clear code word to each letter so that spelling stays understandable over a noisy radio or phone line. Pilots, air traffic controllers, emergency services, and amateur radio operators use it every day to read out call signs, license plates, and confirmation codes without mix-ups. This wheel turns that drill into a quick game. Spin it and try to recall the word before the pointer lands, or use it to quiz a study partner. Because every one of the 26 slices has equal odds, you get an even mix of letters over a session rather than the same few coming up again. Teachers can put it on a screen for a spelling warm-up, and hobbyists can use it to practice reading back a code word on the spot.
26 slices: odds, streaks and repeats
Each of the 26 slices wins a spin 1 in 26, or 3.8%. That sounds rare, yet repeats arrive early: by spin 7 the chance that some entry has already come up twice passes 50%, the same maths as the birthday problem. Landing on every one of them, from Alfa to Zulu, takes about 100 spins on average, which is why a no-repeat round is the quicker way to work through the whole list.
Tips for spinning it in front of a group
- At 13.8° per slice the labels shrink, so on a projector use Present: the wheel fills the screen and each entry passing under the pointer, Alfa through Zulu, is shown live in large type. Space or Enter spins and Esc returns to the page.
- Tick Remove after pick and each winner leaves the wheel: 26 spins work through all 26 entries with none drawn twice, and Reset round puts Alfa and the rest back.
- To bring one up more often, add a weight to the end of its line, such as "Alfa *2": it then lands 7.4% of the time and every other slice 3.7%.
Frequently asked questions
What is the NATO phonetic alphabet used for?
It spells letters out as clear code words like Alfa, Bravo, and Charlie so they cannot be muddled over a radio or phone line. This wheel holds all 26 of those words, one for every letter of the alphabet.
How can this wheel help me learn or practice the phonetic alphabet?
Spin to land on a random code word, then try to recall the letter it stands for before you check, or work the other way from letter to word. Since there are 26 equal slices, every word from Alfa to Zulu is equally likely to come up.
Why does the wheel say "Alfa" instead of "Alpha"?
The official NATO spelling uses "Alfa" and "Juliett" so speakers of many languages pronounce them correctly. The wheel keeps these standard spellings, though you can retype any entry if you prefer a different form.
