Army Modernization: Better Schedule and Cost Information Needed to Support Scaling Battlefield Network

What GAO Found The Army’s two efforts to modernize its battlefield networks—the nearer-term Command and Control Fix (C2 Fix) and the longer-term Next Generation Command and Control (NGC2)—seek to make command and control more adaptive, survivable, and better suited for modern large-scale combat operations. Representation of Evolution of Battlefield Network Through Next Generation Command and Control (NGC2) The Army’s approach to developing C2 Fix and NGC2 incorporates some key elements of an iterative business case. For example, the Army is using a flexible acquisition approach that collects user feedback and makes changes based on evolving market conditions and product capabilities. However, the Army has not taken important steps to implement other key elements that could position the Army to assess the scalability of these efforts. Specifically: The Army developed short-term schedules for NGC2 through fiscal year 2027 with a tentative goal of fielding NGC2’s full technology stack across 11 divisions and four corps by the end of fiscal year 2032. However, the Army is not well positioned to assess its ability to meet this timeline because it has not developed a detailed schedule that identifies the specific units, by fiscal year, that will receive the modernized capabilities. The Army identified NGC2 costs through fiscal year 2026 in documentation supporting the President’s fiscal year 2026 budget submission totaling approximately $3.3 billion. However, the Army has limited visibility into long-term costs because it has not completed an initial cost estimate for the life cycle of the collective effort. The absence of a detailed schedule and long-term cost data limits the Army’s ability to assess whether it has the time and resources it needs to meet its tentative goal for fielding NGC2 across the service by 2032. This gap risks access to secure and reliable communications that soldiers in the field need for modern large-scale combat operations. This information would also better position the Army and Congress to be able to make informed decisions about how to proceed with this effort. Why GAO Did This Study The Army’s modernization strategy seeks to provide soldiers with network technologies to command and control forces across vast terrain and multiple domains (i.e., land, sea, air, space, and cyberspace). As part of this strategy, the Army is focusing its modernization efforts on developing a mobile system of hardware, software, and infrastructure for reliable and secure communications. Senate Report 118-188 includes a provision for GAO to review the Army’s battlefield network modernization efforts. This report addresses (1) how the Army’s modernization approach for battlefield command, control, and communications networks enables it to meet evolving user needs and clearly specify the product to be provided; and (2) the extent to which the Army assessed its ability to scale NGC2 across the military service. GAO reviewed Department of Defense policy and guidance, requirements and planning documents, and Army budget requests. GAO evaluated if, and how, the Army developed cost and schedule estimates; and compared the Army’s two battlefield network modernization efforts against GAO’s leading practices for innovative product development, specifically the key elements of an iterative business case for target schedule and internal value. GAO also spoke with Army officials.
