What is the code word for the letter D?

• A. Alpha
• B. Bravo
• C. Delta
• D. Echo

Answer: (C)

In radio communications, each letter has a specific code word to prevent mishearing in noisy conditions. For the letter D, the code word is Delta. Using Delta makes it clear when spelling out names or ship designations over the radio, reducing confusion with other letters that can sound similar. This code set—NATO phonetic alphabet—is standard in Coast Guard, aviation, and military operations. The other code words map to the other letters: Alpha for A, Bravo for B, Echo for E.
