GCCS is on the third version of its COE, with a goal of providing yearly software releases. The Global Combat Support System, or GCSS, initiative does for combat support what GCCS does for C2. GCSS will permit information flow across defense component combat support systems, and with combat areas. The concept of the GCSS is that mission support computing and communication capabilities will be integrated from the desktop to the mainframe and from the sustaining base to the deployed units. GCSS has a strong mission focus and an effective technical strategy.
Communications is the foundation to successful information flow to the warfighter.
The Defense Information Systems Network, or DISN, is DoD's consolidated worldwide enterprise-level telecommunications infrastructure. It will provide voice, text and imagery transport services when and where needed. Acquisition for support services, switched services and band width management, transmission and video are in progress today. The department continues enhancing tactical communications to provide secure, survivable and interoperable systems for joint and combined operations of conventional forces. Acquisition of new tactical communications systems continues, such as the Single Channel Ground and Airborne Radio System for which DoD has approved a second full-rate production source.
