The HF-GCS is used by the United States Air Force to send instructions for their operations through messages, and most commonly send Emergency Action Messages (EAMs). The HF-GCS is not exclusive to the USAF, and is used by other countries too, but not as often. They also send higher priority messages known as “Skyking Messages” which will even be read over-top and interrupt an EAM to be read. Both of these messages are time sensitive and are read live in NATO Phonetic letters.
The primary HF-GCS frequency is 11175 kHz, and it transmits 24/7 on that frequency as well as 8992 kHz. The HF-GCS also transmits on 4724, 6712 (Croughton), 6739, 13200, and 15016 during their scheduled times, which is still most of the day.
The High Frequency (HF) Global Communications System (HFGCS) supports war plans and operational requirements for the following organizations: White House Communications Agency (WHCA), Joint Chiefs of Staff (JCS), Air Mobility Command (AMC), Air Combat Command (ACC), AF Air Intelligence Agency (AIA), Air Force Materiel Command (AFMC), Air Force Space Command (AFSPC), United States Air Forces in Europe (USAFE), Pacific Air Forces (PACAF), and Air Weather Service (AWS).
