This book provides information on the issue of the capabilities and affordability of the FCS program. The Future Combat System (FCS) is the U.S. Army's multi-year, multi-billion dollar program at the heart of the Army's transformation efforts. It is the Army's major research, development, and acquisition program consisting of 14 manned and unmanned systems tied together by an extensive communications and information network. The FCS program exists in a dynamic national security environment which could significantly influence the program's outcome. The primary issues presented to 110th Congress are the capabilities and affordability of the FCS program, and the likelihood, given a myriad of factors, that the Army will be able to field its first FCS-equipped brigade by 2014 and eventually field up to 15 FCS-equipped brigades. This book will address a variety of issues including the program's timeline, budget, program management issues, current program developmental progress and challenges, and FCS's relevance in the current and potential future security environments.
