The NATO phonetic alphabet is a Spelling Alphabet, a set of words used instead of letters in oral communication (i.e. over the phone or military radio). Each word ("code word") stands for its initial letter (alphabetical "symbol"). The 26 code words in the NATO phonetic alphabet are assigned to the 26 letters of the English alphabet in alphabetical order as follows:
Symbol | Code Word | Morse Code |
Phonic (pronunciation) |
---|---|---|---|
A | Alfa/Alpha | ● ▬ | AL FAH |
B | Bravo | ▬ ● ● ● | BRAH VOH |
C | Charlie | ▬ ● ▬ ● | CHAR LEE |
D | Delta | ▬ ● ● | DELL TAH |
E | Echo | .● | ECK OH |
F | Foxtrot | ● ● ▬ ● | FOKS TROT |
G | Golf | ▬ ▬ ● | GOLF |
H | Hotel | ● ● ● ● | HOH TELL |
I | India | ● ● | IN DEE AH |
J | Juliett | ● ▬ ▬ ▬ | JEW LEE ETT |
K | Kilo | ▬ ● ▬ | KEY LOH |

Morse code transmits text through on-off tones, light-flashes or clicks. It was widely used in the 1890s for early radio communication, before it was possible to transmit voice. Because Morse code has a long range, it was also used to transmit the international maritime emergency frequency (500 kHz), which was monitored by NATO ships at sea until the late 1990s. The SOS distress signal (...---...) is probably the best known message in Morse code.
Ships use flags as signals to send out messages to each other. The use of flags, known as flaghoist communication, is a fast and accurate way to send information in daylight. Used individually or in combination, flags can form any sentence. One famous example is "England expects that every man will do his duty", a signal sent by Vice Admiral Horatio Nelson from his flagship during the Battle of Trafalgar in 1805.
Semaphore is a system in which a person sends information at a distance using hand-held flags – depending on the position of the flags, the message will vary. The signaller holds the flag in different positions that represent letters or numbers.
Panels are visual signals for sending simple messages to an aircraft. Using a limited code, ground forces can send messages to pilots, for example to request medical supplies.
