WASHINGTON - US President Donald Trump on Monday said he was ordering the creation of a sixth branch of the military to focus on space. We must have American dominance in space," Trump said before a meeting of his National Space Council. "We are going to have the Air Force and we're going to have the 'Space Force'. The idea of a space force has been raised before, by Trump and previous administrations, with proponents saying it would make the Pentagon more efficient. Air Force Chief of Staff General David Goldfein told a 2017 congressional hearing that creating a new space branch would "move us in the wrong direction".
