I have to disagree with you entirely on this. The phonetic alphabet is used in many service, such as law enforcement, emergency medical, DOD, etc. Additionally, its not useless. Even under the best of audio clarity and strongest signal strength, many letters sound the same, such as c and d, y and I, m and n, and so on. When you have a critical message and/accuracy of spoken letters matter, the phonetic alphabet is an extremely useful tool. Taking those letters that sound the same and trying to distinguish them when the signal to noise ratio is 0.2:1, and it becomes even more useful.
