The Kill Chain: Defending America in the Future of High-Tech Warfare

by Christian Brose

Many of the US ships, submarines, fighter jets, bomber aircraft, additional munitions, and other systems that are needed to fight would not be near the war when it started but would be thousands of miles away in the United States. They would come under immediate attack once they began their multiweek mobilization across the planet. Cyberattacks would grind down the logistical movement of US forces into combat. The defenseless cargo ships and aircraft that would ferry much of that force across the Pacific would be attacked every step of the way. Satellites on which US forces depend for intelligence, communications, and global positioning would be blinded by lasers, shut down by high-energy jammers, or shot out of orbit altogether by antisatellite missiles. The command and control networks that manage the flow of critical information to US forces in combat would be broken apart and shattered by electronic attacks, cyberattacks, and missiles. Many US forces would be rendered deaf, dumb, and blind. While these attacks were under way, America’s forward bases in places like Japan and Guam would be inundated with waves of precise ballistic and cruise missiles. The few defenses those bases have would quickly be overwhelmed by the sheer volume of weapons coming at them, with many leaking through. Those bases would have no defense against China’s hypersonic weapons, which can maneuver unpredictably, fly at five times the speed of sound, and strike their targets within minutes of bei...

The kill chain is a process that occurs on the battlefield or wherever militaries compete. It involves three steps: The first is gaining understanding about what is happening. The second is making a decision about what to do. And the third is taking action that creates an effect to achieve an objective.

Specific military systems may be able to work together to facilitate understanding, decisions, and actions for one specific purpose, but they cannot be recomposed in different ways for other unforeseen purposes.

China has rapidly developed arsenals of advanced weapons intended to break apart US battle networks, destroy the US military’s traditional platforms, and shatter its ability to close the kill chain.

The real goal, however, is a more effective kill chain—achieving better understanding, making better decisions, and taking better actions.
