President Trump on Tuesday touted $25 billion in initial funding for the "Golden Dome" and put Space Force Gen. Michael Guetlein in charge of realizing the hemispheric missile shield.
The big picture: Golden Dome — previously dubbed Iron Dome, but separate from Israel's missile defense program — is a mammoth undertaking with enthusiastic backing from the president but many doubters in the national security community.
Trump said the project will cost around $175 billion and be built over the next three years, though those are both just estimates. The initial $25 billion will be included in the "big beautiful bill" working its way through Congress, Trump said.
