The Pentagon has increased its estimated cost of the Golden Dome missile defense system by $10 billion. Gen. Michael Guetlein, the Space Force general leading development of Golden Dome, said Tuesday the new $185 billion cost estimate includes $10 billion that would be used to accelerate procurement of satellites and build out a space-based data network. The program remains in early stages, with broad funding and policy direction in place but limited public detail on its final design. Guetlein pushed back against outside estimates that have put the cost of Golden Dome in the trillions, arguing those figures are based on assumptions about architectures that differ from what the Pentagon is pursuing.
