Extending CommunicationsAs demonstrated, the SUDS payload significantly enhances the Long Range Strike capability of the TSN in a SATCOM denied environment. In other communications centric missions, the SUDS payload will significantly improve connectivity to warfighting platforms and existing users of 5K and 25K DAMA and dedicated channels in SATCOM denied environments.
The SUDS payload also provides an airborne SubNet Relay (SNR) capability in which it participates as a relay node in SNR networks. This enables beyond line of sight data flow across the battle group without SATCOM, eliminating reliance on satellites and decreasing overall network latency.
The SUDS system is a venture into surrogate satellite operations and its proven success represents the potential for continued communications in SATCOM denied environments.
The SUDS payload is controlled using a standardized airborne gateway control suite and hosts the Gateway Manager application to translate tactical SATCOM data to other data links.

SUDS system integrated into the airborne gateways provides UHF DAMA and dedicated SATCOM services
“Since it would be imprudent to assume US space assets will be spared attack, various airborne sensors and components of battle network systems such as Battlefield Airborne Communi-cations Nodes (BACN) should be deployed to provide supple-mentary capability or, in the event of lost space functional-ity, work-arounds.” AirSea Battle: A Point-of-Departure Opera-tional Concept, 2010, Center for Strategic and Budgetary Assessments www.csbaonline.org
