What is the purpose of the Advanced Extremely High Frequency (AEHF) system?

The Advanced Extremely High Frequency (AEHF) system is designed specifically to provide global, secure communications for military operations. This satellite communication system ensures that military personnel can communicate reliably and securely under a variety of conditions, including in contested environments where traditional communication systems might be compromised.

The AEHF system supports a range of communication needs, including voice, data, and video transmissions, which are crucial for command and control operations. Its enhanced security features protect sensitive information from interception, making it a vital component of modern military communication infrastructure. This capability is essential for maintaining operational effectiveness, coordinating logistics, and executing missions in a secure manner.

In contrast, the other options do not align with the primary purpose of the AEHF system. While navigation, commercial data services, and air traffic control are important functions in their own rights, they fall outside the scope of what AEHF is designed to achieve. Thus, option B correctly identifies the AEHF system’s mission of providing secure communication channels for military applications.
