The NATO Phonetic Alphabet
The NATO phonetic alphabet, more formally the international radiotelephony spelling alphabet, is the most widely used spelling alphabet.
The NATO alphabet assigns code words to the letters of the English alphabet acrophonically (Alpha for A, Bravo for B, etc.) so critical combinations of letters can be pronounced and understood by those who transmit and receive voice message by radio or telephone, regardless of their native language. This is especially important when the safety of navigation or persons is essential.
SierraPapa is a simple program to help with learning the NATO phonetic alphabet. In this version, Morse Code has also been provided for the letters & numbers.
