Overview
- Golden Dome, initiated by President Trump in January 2025, aims to create a U.S.-wide missile defense shield against advanced threats, including hypersonic and cruise missiles.
- Defense officials emphasize the complexity of integrating space-based boost-phase interceptors, a key technical challenge described as unprecedented in scale and difficulty.
- Cost estimates for the initiative remain unsettled, with projections ranging from $500 billion to trillions of dollars due to the program's scope and technological demands.
- Pentagon leaders are coordinating across agencies to unify existing missile defense systems with new technologies, with preliminary funding expected in the FY 2026 budget request.
- The initiative reflects heightened concerns over emerging missile threats from Russia and China, but experts warn of logistical and strategic hurdles in scaling the Iron Dome model to U.S. geography.
