Missile Defense Project

Authoritative analysis on missile defense and related issues

The Missile Defense Project at CSIS looks at a wide range of policy, program, and strategic issues related to missile defense. Technological and geopolitical factors have driven increased global supply and demand for high-velocity, unmanned, missile-based weapons and their corresponding counters. Besides more recognized cruise and ballistic missile threats, global missile proliferation now consists of a spectrum including precision-guided rockets, anti-ship missiles, air defenses, hypersonic delivery systems, and counterspace weapons.
