Overview

• The Golden Dome Act, introduced June 2025 by Senate Republicans with bipartisan backing, authorizes $21–23 billion to begin building a layered homeland defense system modeled on Israel’s Iron Dome
• The plan calls for space-based sensors, missile interceptors, mobile launchers and battle-management systems to detect and defeat ballistic, hypersonic and cruise missile threats
• Lawmakers estimate total program costs at $175–800 billion over 20 years as defense contractors like Lockheed Martin gear up for development and production
• Alaska’s Clear Space Force Base, Fort Greely and Aleutian radar sites will serve as critical nodes in early warning and interceptor deployment
• North Korea and Russia have condemned the initiative as risking a new arms race while supporters argue it is essential to counter threats from Iran, China and other adversaries
