Which phonetic alphabet word corresponds to the letter 'U'?

The phonetic alphabet is used to clearly communicate letters over radio and telephone transmissions, especially in environments where clarity is crucial. Each letter of the alphabet is represented by a specific word to prevent confusion. The word that corresponds to the letter 'U' in the phonetic alphabet is "Uniform." This word is specifically chosen for its distinct sound and the fact that it does not sound similar to other letters, which helps avoid miscommunication.

In the context of the phonetic alphabet, words like "Victor," "Whiskey," and "X-ray" represent different letters (V, W, and X, respectively). While they are also part of the phonetic alphabet, they are not associated with the letter 'U'. Therefore, "Uniform" is the correct choice as it directly corresponds to 'U'.
