President Donald Trump on December 20 signed into law the US Space Force, the sixth military branch and first devoted to organizing, training, and equipping personnel to use and defend military space assets.
Trump signed a directive organizing the Space Force as part of the Air Force in February. With the 2020 National Defense Authorization Act that Trump signed Friday, US Air Force Space Command becomes Space Force but remains within the Air Force, much like the Marine Corps is a part of the Navy Department.
“Going to be a lot of things happening in space, because space is the world’s newest warfighting domain,” Trump said Friday. “Amid grave threats to our national security, American superiority in space is absolutely vital … The Space Force will help us deter aggression and control the ultimate high ground.”
