President Trump aims to spend around $175 billion on his ambitious new missile-defense system, Golden Dome, before his term ends. The plan would seek to detect and destroy missiles launched from anywhere in the world, but experts say it faces steep technical challenges and budget concerns. The administration wants Golden Dome to combine ground-based interceptors, a network of sensors in orbit, and satellites designed to destroy incoming missiles shortly after launch. Some of the key components, such as ground interceptors and space sensors, already exist but are in very limited supply, while other parts remain experimental. “All of the systems comprising the Golden Dome architecture will need to be seamlessly integrated,” Defense Secretary Pete Hegseth said last week when he named a new director to oversee the project. That integration task will be complex, since US agencies already operate a variety of public and secret satellites that can detect missiles. These satellites would all have to be linked under a unified command, rather than managed separately as they are today. Building a fresh layer of orbital interceptors could take many years and demand billions more. Analysts and former military officers say an effective orbital shield might require thousands of satellites to catch missiles reliably. Those systems would also have to adapt quickly, since potential foes could use decoys or other tricks to hide real warheads. Golden Dome’s total cost remains uncertain President Trump recently said the effort would run about $175 billion over the coming years. The Congressional Budget Office has offered estimates as high as $831 billion, in part by looking at past rocket-launch expenses. And Senator Tim Sheehy of Montana warned that the full project could reach into the trillions over time. Last week, House Republicans approved spending $25 billion as a first installment on the Golden Dome.…
