He forecast that the project would be complete before the end of his term and estimated that the total cost of the project would be $175 billion. He said that an initial $25 billion would be earmarked in a sweeping spending package , which is currently being weighed by Congress. The Golden Dome is similar to Israel’s missile deterrent system, the so-called “Iron Dome,” which has been in use since 2011.
