This is not the first time that Trump has mentioned a specific military branch or "space force" dedicated to space. Trump has previously said that he included a Space Force as part of his national space strategy but also said in March that he not really serious about the idea.
Army, Navy, Air Force, Marines, Coast Guard. and Space Force? It includes protecting the nation's control over "assets" of space, including US control over commercial access, and a series of plans to document debris that could pose a danger to Earth.
Congressional leadership first floated the creation of sixth branch of the armed forces focused on space combat (sadly, not against invading alien insects though) a year ago... and Mattis promptly blasted the idea. However, it is also likely unnecessary, unwise, and runs counter to the recommendation of Trump's own Defense chief.
The president also used the White House event to establish a new policy for reducing satellite clutter in space.
Look out, all you Air Force hotshots.
In a letter to lawmakers previous year, Defense Secretary James Mattis "strongly" urged Congress to reconsider a proposal to establish a separate "Space Corps", saying it was "premature" to set up a new organization "at a time I am trying to reduce overhead".
Dunford appeared to acknowledge the order, responding, "we got it".
The plane's military use is a well-kept secret, but we'll assume it wasn't meant for "space force". "It is not too late to consider a more careful, thoughtful, conditions-based approach to assess if and when an autonomous military space armed force is the best path forward". "The whole point of today's meeting was not about this at all, it was about the space traffic management policy decision", said Brian Weeden, the director of program planning for the Secure World Foundation (which focuses upon space policy). This document concerns monitoring objects in orbit and sharing the information so spacecraft can avoid collisions.
"I said maybe we need a new force; we'll call it a space force".
