CBAS (Continuous Broadcast Augmenting SATCOM) is a geostationary satellite to provide communications relay capabilities to support senior leaders, combatant commanders, augmenting existing military satcom.
CBAS is managed by the Military Satellite Communications Directorate of the U.S. Air Force’s Space and Missile Systems Center. The mission of CBAS is to augment existing military satellite communications capabilities and broadcast military data continuously through space-based, satellite communications relay links.
The mass of CBAS is estimated to be between 2000 and 3000 kg. The satellites are built by Boeing.
CBAS 1 was launched in 2018 as the prime payload on the AFSPC 11 mission on an Atlas-5(551)¹ rocket directly into geostationary orbit.
CBAS 2 was launched in January 2023 on a Falcon-Heavy (Block 5)(px) on the USSF-67 mission.
