Scope includes the Life Cycle Sustainment (LCS) of C5ISR systems including in-service and engineering support, Integrated Product Support (IPS), technical data and configuration management, and technical and project management support. Systems consist of, but are not limited to, Radio Frequency (RF) communications systems, antenna systems, baseband audio/video data systems, signal routing/patching/monitoring, Communications and Electronic (C-E) remote control, Information Technology (IT), power/signal distribution, and Audio Video (AV) and Video Teleconference (VTC) systems (referred to as systems/subsystems throughout the remainder of this SOW). This includes legacy, current, and future C5ISR systems and the in-service engineering support, IPS, C-E equipment/systems and subsystems training, and technical data and configuration management support of those systems/subsystems.
