U.S. President Donald Trump unveiled a plan for his ambitious "Golden Dome" missile defense shield this week, stating it will cost $175 billion and take about three years to develop — but some experts say the price tag could be many times higher.
The Golden Dome project aims to see the United States design and deploy a next-generation missile defense shield over the entire continental U.S. that will be able to detect, track and intercept hypersonic missiles and other advanced aerial threats. What makes Golden Dome unique is that it will feature space-based interceptors: spacecraft in Earth orbit capable of shooting down missile threats mid-flight.
