The NATO phonetic alphabet is a spelling alphabet used by airline pilots, police, the military, and other officials when communicating over radio or telephone. The purpose of the phonetic alphabet is to ensure that letters are clearly understood.
More formally known as the international radiotelephony spelling alphabet, the NATO phonetic alphabet was developed in the 1950s as part of the International Code of Signals (INTERCO), which originally included visual and sound signals.
Here are the phonetic letters in the NATO alphabet:
Alfa (or Alpha)
