Which term corresponds with the letter "S" in the phonetic alphabet?

The term that corresponds with the letter "S" in the phonetic alphabet is "Sierra." The phonetic alphabet, also known as the NATO alphabet or ICAO phonetic alphabet, is used to clearly communicate letters over radio and telephone communications, particularly in aviation and military contexts. Each letter is assigned a specific word to avoid confusion that can arise from similar-sounding letters.

"Sierra" is specifically designated for the letter "S," and its use helps ensure that recipients clearly understand the intended character, especially important in environments where miscommunication could lead to serious errors. The terms "Tango," "Uniform," and "Victor" correspond to "T," "U," and "V," respectively, which, while also part of the phonetic alphabet, do not represent the letter "S." This precision and clarity are crucial in aviation communications for safety and operational efficiency.
