What is AEHF?

AEHF (Advanced Extremely High Frequency) is a U.S. military satellite communications system. It provides secure, jam-resistant, and survivable communications for strategic command and control, as well as tactical warfighters operating on land, sea, and air. AEHF satellites operate in the EHF frequency band and are designed to withstand nuclear attacks and other forms of interference, ensuring reliable communication even in contested environments.
