The United States Air Force (USAF) is the aerial warfare service branch of the United States Armed Forces and one of the seven American uniformed services. Their Military Satellite Communications Systems Wing (MCSW) is an organization headquartered at Los Angeles Air Force Base, located in El Segundo, California, a state located in the West Coast of the United States.  The Space & MIssile Systems Center established the MILSATCOM Systems Wing on August 1, 2006. MCSW is previously known as the MILSATCOM Joint Program Office (MJPO).

Air Force Space Command (AFSPC) is a major command of the United States Air Force, with its headquarters at Peter Air Force Base, Colorado. MCSW is one of its several wings and other units that make up its Space and Missile Systems Center (SMC).

MCSW has five groups and one squadron which deliver three primary Satellite Communications (SATCOM) product lines:
The Protected Communications Group Provides the United States Department of Defense (DoD), the US federal department charged with coordinating and supervising all agencies and functions of the government relating directly to national security and the United States armed forces, survivable, global secure, protected, jam-resistant communications for high priority military ground, sea, and air assets. 

They provide operations and sustainment to the on-orbit Milstar Communications satellite constellation in geostationary orbit, originally Military Strategic and Tactical Relay, operated by the United States Air Force, and provide secure and ham resistant worldwide communications to meet the requirements of the Armed Forces of the United States. 

In addition, the group executes the $6.7B Advanced Extremely High Frequency (AEHF), a series of communications satellites operated by the United States Air Force Space Command, and $1.2B Enhanced Polar SATCOM (EPS) programs. Ther user equipment or terminals for the DoD protected communication systems in the currently operational Milstar Command Post Terminal (CPT) and $3.2B Family of Advanced Beyond-Line-of-Sight Terminals (FAB-T) development program.  

The Wideband Communication group provides worldwide, high-volume, voice and data communications to the warfighter. They provide operation and sustainment support for the on-orbit Defense Satellite Communications system (DSCS) constellation, which provides the United States with military communications to support globally distributed military users. 

In addition, the group executes the $1.9B Wideband Global SATCOM system (WGS), a high-capacity satellite communications system planned for use bin partnership by the United States Department of Defense (DoD) and the Australian Department of Defence, and $0.9B Global Broadcast Service (GBS), a combined United States space and Command, control, Communications, and Intelligence (C3I) system, that provides a one-way Wideband/High-Throughput of Information to forces garrisoned, deployed, or on the move. Wideband communication terminals include the Ground Multi-band Terminal (GMT), the High Data Rate - Radio frequency (HDR-RF) ground terminal program which is an evolutionary upgrade to the GMT, and the FAB-T Increment 2.

The Transformational Satellite Communications System (TSAT) program, a United States Department of Defense (DOD) program sponsored by the US Air Force for a secure, high-capacity global communications network serving the Department of Defense, NASA and the US Intelligence Community, was the DoD’s future MILSATCOM System. The $24.0B TSAT system was meant to provide real-time connectivity of all Global Information Grid (GIG) assets; provide Battle Command-On-The-Move capability for Small Mobile Units; worldwide persistent connectivity of high/low resolution Intelligence Surveillance and Reconnaissance; and survivable communications for Strategic Forces. The Global Information Grid (GIG) is an all-encompassing communications project of the United States Department of Defense. The TSAT program office consisted of the TSAT Network Integration Group, the TSAT Space Group and the TSAT Mission Operations Group. This program currently appears to have been cancelled.
