Golden Dome: A New Frontier in U.S. Missile Defense
The Golden Dome, a multi-layered missile defense system, is being developed by the Trump administration. Comprising four integrated layers, the system faces a 2028 completion deadline and an estimated $175 billion cost. It aims to protect the U.S. from global threats with significant technological and strategic investments.

The Trump administration's ambitious Golden Dome missile defense project aims to bring unprecedented protection to the United States. Comprising four integrated layers, the system will utilize satellite and land-based technologies, aiming for completion by 2028. However, the project faces several challenges, including undefined system architecture and an estimated cost of $175 billion.
Presented to defense contractors in Huntsville, the project's detailed plans reveal a complex architecture. Key components include space-based missile targeting and multiple land-based interceptors, with a new missile field possibly located in the Midwest. The U.S. currently has Ground-Based Midcourse Defense sites in California and Alaska.
Despite significant appropriations, uncertainties about basic configurations persist. The Pentagon is also seeking industry, academic, and government collaboration. Overcoming technical hurdles like communication latency and developing new interceptors remain critical, while Space Force General Michael Guetlein leads the charge to actualize these defense innovations.
