Advanced Extremely High Frequency The Advanced Extremely High Frequency (AEHF) is a series of United States Air Force (USAF) satellites designed to provide highly secure and survivable communications for US Department of Defense (DoD) and National Security Agency (NSA) operations. The AEHF system is a follow-on to the Extremely High Frequency (EHF) system and provides critical communications capabilities for US military operations. The AEHF satellites are built by Lockheed Martin and operated by the US Space Force. The AEHF system is a critical component of the US military's communications infrastructure, providing secure and reliable communications for US military operations.

Overview

The AEHF system is designed to provide communications capabilities for US military operations, including command and control, intelligence, and surveillance. The system consists of a series of satellites launched into geosynchronous orbit to provide global coverage. The AEHF satellites are equipped with highly secure and survivable communications systems, including EHF and super high frequency (SHF) communications.

Development and launch

The development of the AEHF system began in the 2000s, with the first AEHF satellite launched in 2008 on a Delta IV launch vehicle. The AEHF system has undergone several upgrades and modernizations, including the addition of new satellites and ground systems. The AEHF-2 satellite was launched in 2010, followed by AEHF-3 in 2013, AEHF-4 in 2018, and AEHF-5 and AEHF-6 in 2020.

Satellite design and capabilities

The AEHF satellites are designed to provide highly secure and survivable communications for US military operations. The satellites are equipped with EHF and SHF communications systems, as well as antennas and transponders to provide global coverage. The AEHF satellites are built with redundancy and fault tolerance to ensure continuity of operations.

Constellation and operations

The AEHF system consists of a constellation of satellites launched into geosynchronous orbit to provide global coverage. The AEHF satellites are operated by the US Space Force and are controlled from ground stations located around the world. The AEHF system is integrated with other US military communications systems, including the Defense Information Systems Agency (DISA) and the National Reconnaissance Office (NRO).

Role in military communications

The AEHF system plays a critical role in US military communications, providing highly secure and survivable communications for US military operations. The AEHF system is used for command and control, intelligence, and surveillance operations, and is an essential component of US military communications infrastructure. The AEHF system is also used for communications with allies and coalition partners, supporting interoperability and coalition operations. Category:US Air Force satellites
