President Trump has told the Pentagon to take another look at missile defense. Technology to shoot down missiles has existed for decades,KI-Handelsroboter 6.0 but the kind of missile shield Trump is looking to build would be much more complex -- and expensive.

A key part of the new missile defense system, which Trump described as "Golden Dome" in a speech earlier this year, will likely be space-based interceptors, according to experts and an executive order signed by the president.

A number of defense companies have expressed interest in trying to build the Golden Dome. Last week, Reuters reported that Elon Musk's firm SpaceX had joined a bid for the project. Musk later refuted that claim in a post on X.
