Golden Dome cost estimate grows to $185B

Space Force General Michael Guetlein revealed Tuesday that the Golden Dome missile defense system will cost approximately $185 billion, a nearly 50 percent increase from President Trump's initial $125 billion estimate. The system, modeled after Israel's Iron Dome air defense technology, is designed to protect U.S. territory from airborne threats and represents a major investment in space-based defense capabilities. The cost escalation signals potential budget pressures as the Trump administration prioritizes accelerating space defense infrastructure amid evolving global security concerns. Congress will need to approve the increased funding, which represents a significant commitment of defense dollars at a time when lawmakers are scrutinizing major weapons programs. The project reflects the administration's focus on modernizing U.S. missile defenses and expanding operational capabilities in space.
