Which term is used to describe the letter 'Z' in the phonetic alphabet?

The term used to describe the letter 'Z' in the phonetic alphabet is 'Zulu.' The phonetic alphabet, often utilized in military and communication contexts, assigns specific words to letters to ensure clarity and understanding over radio or telephone communications, especially in situations where similar-sounding letters can lead to confusion. 'Zulu' is the word chosen to represent 'Z' because it is distinctive and easily understood, even in noisy environments.

Other terms such as 'Zebra,' 'Zenith,' and 'Zipper' are not part of the phonetic alphabet used by the U.S. Navy or other branches of the military. The purpose of the phonetic alphabet is to have universally recognized words that correspond with each letter of the alphabet, and 'Zulu' fulfills this requirement effectively for 'Z.'
