Golden Dome Missile Defense Shield

August 19 , 2025 17 hrs 0 min 14 0
  • Golden Dome (GD) is a U.S. missile defense system designed to protect against enemy intercontinental ballistic missiles (ICBMs).
  • The system aims to intercept missiles in the “boost phase”—just after launch—using a network of space-based satellites, interceptors, and possibly lasers.
  • Golden Dome will have four defense layers:
    • Space-based intercept layer using satellites.
    • Enhanced Ground-Based Midcourse Defense (GMD) system in California and Alaska.
    • Five new land-based launch sites (three in mainland U.S., one in Alaska, one in Hawaii).
    • Limited Area Defense for cities, combining new radars, a common launcher, and systems like the Patriot missile defense.
  • Iron Dome protects small areas from rockets, while GD aspires to nationwide, multi-layered missile interception.
