Future Combat Systems (FCS) was a program initiated by the U.S. Army aimed at modernizing military capabilities through advanced technology. It focused on developing a networked system of systems that integrated various platforms, including ground vehicles, unmanned systems, and sensors, to enhance situational awareness and combat effectiveness. The program sought to improve the Army's ability to conduct joint operations and respond to diverse threats. However, FCS faced challenges, including budget constraints and technological hurdles, leading to its cancellation in 2009. Despite this, many concepts from FCS influenced future military modernization efforts.
