President Trump announced the chosen design for the $175 billion Golden Dome missile defense shield, aimed at protecting the U.S. from threats posed by China and Russia. The system will use satellites and space-based interceptors to detect and neutralize missiles. Trump appointed Space Force General Michael Guetlein to lead the program, targeting operational status within three years. The project has strong bipartisan support but faces scrutiny over costs, which could reach $831 billion over 20 years. The initiative highlights the administration’s focus on advancing missile defense technology against emerging global threats.
