President Trump on Tuesday announced his administration has selected the architectural design for a "Golden Dome" missile defense system to protect the United States from foreign threats. The president also said the budget package Republicans are currently ironing out on Capitol Hill will include an initial $25 billion to begin construction on the missile defense system.

Trump offered new details about his ambitious Golden Dome missile shield project, which he expects to have a price tag of around $175 billion and be completed before the end of his term.

The Congressional Budget Office estimated this month that just the space-based components of the Golden Dome could cost as much as $542 billion over the next 20 years.
