The White House is seeking funding for the Golden Dome program, with reported requests ranging from $17.5 billion to $18 billion, although the overall cost of the program may be as high as $185 billion. The funding for the program is uncertain and may depend on reconciliation. Lawmakers are seeking more information about the program's costs and details, while the development of space-based interceptors for Golden Dome is ongoing, with 12 companies selected to work on the project.
