AEHF-5 is the fifth satellite to be launched in the US Air Force’s Advanced Extremely High Frequency (AEHF) program. This is a system of satellites dedicated to providing global survivable, secure, protected and jam-resistant communications to the armed forces of the United States and her allies.

AEHF serves to augment the legacy Milstar communications system, a network of satellites deployed from 1994 to 2003 with which it is designed to be backward-compatible, as they approach the end of their service lives. AEHF will eventually replace the Milstar system, ensuring uninterrupted service to its users.
