Frequently Asked Questions

What is the NATO phonetic alphabet?

The NATO phonetic alphabet is the spelling alphabet used by NATO, ICAO aviation and most militaries since 1956. It assigns a codeword to each letter — Alfa, Bravo, Charlie through Zulu — so letters cannot be misheard over radio.

Is this reference free to use?

Yes. Every tool — converters, Morse audio, quiz drills — is free, requires no signup, and works offline once loaded. Content is licensed CC BY-NC 4.0.

What is the difference between military time and Zulu time?

Military time is the 24-hour clock (0000–2359) in your local zone. Zulu time is military time fixed to UTC, marked with a Z suffix: 1500Z means 3:00 PM UTC everywhere in the world.
