Answer: United States
Notes: The US President recently announced a 175 billion dollar Golden Dome missile defence shield for the United States. It is a ground and space-based system designed to protect the country from advanced missile threats. Golden Dome will use a network of satellites to detect, track and intercept incoming missiles, including long-range ones from space or other continents. It will integrate with existing US defence systems like Patriot, THAAD (Terminal High Altitude Area Defence), Aegis Ballistic Missile Defence and Ground-based Midcourse Defence (GMD).
