What project C34 buys

Project C34: Army Tac C2 Sys Eng FY 2027 and beyond was realigned to PE 0655333A/C2 Infrastructure, Project C2H, C2 Systems Engineering as part of a new funding structure for the Next Generation Command and Control (NGC2) investment to modernize Command and Control (C2) systems for the Infrastructure Layer. Project C34, Army Tactical Command and Control Systems Engineering supports the Army's Network Modernization Strategy and coordinates technical efforts across and outside of CPE Command, Control, Communications, and Network (C3N) to ensure integration with the current and future Mission Command Network. Project C34 provides technical support to programs, informing design and solutions with specific emphasis on the ability for different program efforts to be integrated and interoperable with one another. Efforts support Army Modernization priorities including Army Unified Network Plan, Multi-Domain Operations, Joint All Domain Command and Control (JADC2), Data Modernization and emerging data-centric requirements. This project provides the CPE C3N System of Systems (SoS) engineering and integration, acquisition management, testing, fielding and sustainment support to ensure interoperability and affordability within the CPE C3N portfolio. The effort focuses on SoS Engineering and Integration for the Mission Command Network with increased emphasis on immediate Warfighter needs as well as leveraging emerging technologies.
