President Donald Trump has announced the concept he wants for his future Golden Dome missile defense program — a multilayered system that for the first time will put U.S. weapons in space.

President Donald Trump picked a design for his Golden Dome missile defense system and named a leader of the ambitious $175 billion defense program. The program, first ordered by Trump in January, aims to create a network of satellites, perhaps numbering in the hundreds, to detect, track and potentially intercept incoming missiles.
