A highly informative article has been posted at SpaceNews entitled "Space reforms coming: 2018 NDAA drops legislative bombshells on U.S. Air Force."
In the article by Sandra Erwin, the U.S. Air Force is blasted by the National Defense Authorization Act (NDAA) as a "broken national security space enterprise." Military space management for the most part, will now be handled by the Deputy Secretary of Defense, with the House of Representatives insisting that the NDAA being a move toward "fundamental reform of national security space."
