Overview

  • The Golden Dome initiative aims to create a comprehensive missile defense system capable of neutralizing threats from ballistic, hypersonic, and cruise missiles at all four stages of an attack.
  • The system will integrate existing defense assets like Patriot batteries and surveillance satellites with next-generation space-based sensors and interceptors.
  • Inspired by Israel’s Iron Dome but on a much larger scale, the Golden Dome will include a fleet of satellites designed to intercept missiles shortly after launch.
  • The $175 billion proposal, announced earlier this month, is one of the largest defense projects in decades and faces scrutiny over feasibility, cost, and compliance with international treaties.
  • The Pentagon and US Northern Command are actively drafting an initial capabilities document to define system requirements and guide early development stages.
