President Donald Trump announced that Gen. Michael Guetlein, the second-highest-ranking Space Force officer, will lead the Pentagon’s development of his Golden Dome air defense system.

One of the president’s first acts in his second term was to sign an executive order calling for the construction of a multilayered aerial defense system, both ground and space-based, to defend the United States against a range of strategic weapons, including ballistic, hypersonic, and advanced cruise missiles fired from different platforms.
