The Golden Dome aims to shoot missiles out of the sky before they reach U.S. soil, similar to Israel’s Iron Dome. The push to diversify the project comes as Trump repeatedly threatened to sever all federal ties with SpaceX following his and Musk’s spectacular falling-out.

The new US missile defense system will explore alternatives to Elon Musk's SpaceX, with Amazon. com's Project Kuiper among the main contenders.

Trump has officially iced out Elon Musk’s SpaceX from the heart of his $175 billion Golden Dome missile defense project and is now pulling in Jeff Bezos’ Amazon instead. The decision comes directly from the White House after Trump and Elon’s relationship collapsed publicly on June 5.
