The International Wideband Global SATCOM (WGS) Program
November 28/18: Anti-jam Boeing is being contracted to support the DoD’s Protected Tactical Enterprise Service program. Awarded by the Space and Missile Systems Center, the $383 million contract provides for development of a ground system that protects tactical satellite communications from enemy jamming. The Protected Tactical Enterprise Service (PTES) will be a hub-and-spoke system that reaches out to tactical warfighters and uses the WGS constellation. It will tap the Protected Tactical Waveform (PTW), which the government developed to provide secure communications in a frequency-agnostic format. The US military relies on a complex set of Military Satellite Communication (MILSATCOM) and tactical networks. These networks transport command and control (C2), sensor, and intelligence, surveillance, and reconnaissance (ISR) information to enable timely and decisive operations. As electronic threats against satellite communication are rapidly advancing the US military needs more robust networks that allow its warfighters to securely and effectively communicate in the most congested electronic environments. Work will be performed at Boeing’s facility in El Segundo, California, and is expected to be completed by December 31, 2025.
The US military needs a bigger data firehose. In an era of streaming data from proliferating UAVs and other persistent surveillance platforms, and the need for control of those systems anywhere in the world, bandwidth is almost as important as fuel. Commercial satellite communications (SATCOM) can fill some of the gaps, but it’s expensive, and may not be available when needed. The Wideband Gapfiller SATCOM (now Wideband Global SATCOM) program began as a way to ease these problems in the near term, but went on to become one of the twin pillars of US military communications, alongside the hardened AEHF constellation. Both satellite types expanded their roles after the super-high bandwidth T-SAT program was canceled. Instead, the USA is adding WGS and AEHF satellites in space, even as it makes both programs multi-national efforts here on earth.
WGS is a set of 13-kilowatt spacecraft based on Boeing’s model 702 commercial satellite. These satellites will handle a significant portion of the USA’s warfighting bandwidth requirements, supporting tactical C4ISR(command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. Upon its 2007 launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. WGS F4, launched in January 2012, offers further improvements, as do satellites from WGS F8. The constellation is set to grow to 10, including international participation.
