Siloed Thinking: A Closer Look at the Ground-Based Strategic Deterrent

“Siloed Thinking,” authored by Research Associate Matt Korda, reviews the fundamental role of intercontinental ballistic missiles (ICBMs) in US nuclear strategy and examines the Pentagon’s justifications for pursuing an ICBM replacement program.

The report ultimately suggests that these justifications were based on flawed assumptions, and many have since been deprioritized. The report also suggests that the initial outcome favoring a brand-new ICBM replacement program was largely predetermined by arbitrary force requirements and timelines that have little 21st century strategic rationale.

These conclusions suggest that the Pentagon’s case for the ICBM replacement program, known as the Ground-Based Strategic Deterrent (GBSD) needs to be reevaluated in light of cost escalation and surrounding budgetary pressures.
