WASHINGTON

The Pentagon presented US President Donald Trump with a range of options to develop a “Golden Dome” air and missile defense system that would cost hundreds of billions of dollars, according to a report on Monday.

Trump is set to announce his preferred plan and its price tag in the coming days, a move that will shape how the US proceeds with funding and building the high-tech system over the coming years, CNN reported, citing multiple sources familiar with the plans.

The Department of Defense has already allocated $25 billion in next year’s defense budget, but the Congressional Budget Office estimates the full cost of developing a “viable Golden Dome” could exceed $500 billion over two decades, according to the report.

The system, which draws inspiration from Israel’s Iron Dome, would rely heavily on private contractors, with companies like SpaceX, Anduril, and Palantir already making direct pitches to Defense Secretary Pete Hegseth, the report said.

The Defense Department has confirmed that the agency presented the president with options.

“The Secretary of Defense and other Department leaders have engaged with the President to present options and look forward to announcing the path forward in the coming days,” Pentagon spokesman and senior adviser Sean Parnell was quoted as saying.
