Overnight US President Donald Trump announced the establishment of a “Space Force” as a separate force of the US military.
Departments in the US military currently include the Air Force, the Army, the Navy, the Marine Corps and the Coast Guard.
The announcement of a Space Force is part of Trump’s increased interest in the space domain, having in 2017 revived the National Space Council, under the leadership of Mike Pence.
Trump had previously flagged the idea of a US Space Force with statements in March and May.
However, with this most recent announcement Trump officially directed the US Department of Defense and the Pentagon to establish the Space Force.
Much more will be needed to actually make this happen. The President cannot simply declare the existence of a new branch of the US armed forces – it would also require, at minimum, an Act of Congress and quite possibly something more. Each branch of the US military has its own unique origins and would require the restructure of the Air Force and other oversight mechanisms in the Pentagon.
Further, there is also the question regarding what such a force could do. Trump’s speech flagged some sort of peacekeeping role.
Whilst much of the reportage of Trump’s speech has focused on the military aspects of his announcement, Trump reminded the audience that the Space Force was not the only space activity planned by his administration. Rather there was a strong emphasis on commercial space industries, observing that “rich guys seem to like rockets.”
US laws relating to commercial space are to be updated to encourage commercial space industries, directing government and the private sector to work cooperatively.
Trump’s proposals – as with any other new outer space settlements – must operate within prohibitions laid out in the Outer Space Treaty. Established in 1967, this document is the framework multilateral treaty that establishes the principal rules regulating the exploration and use of outer space.
Article II of the Outer Space Treaty indicates that “Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.”
That said, US law has been drafted to enable access to, including mining of, space resources, without any claim of sovereignty being made.
With respect to a Space Force, Article IV of the Outer Space Treaty expresses a principle of use of space for “peaceful purposes.” Members of the Outer Space Treaty are forbidden from placing nuclear weapons or weapons of mass destruction in orbit around the Earth, on celestial bodies or stationed in outer space. Military bases, installations and fortifications, weapons testing and conduct of military manouevers on celestial bodies are also forbidden.
Of course, none of this has prevented military personnel being involved in space activities and exploration since the dawn of the space age. Both the early US astronauts and Soviet cosmonauts have been members of their respective countries armed forces. Nor has it prevented the transit of weapons of mass destruction through space. GPS is a development of the US Department of Defense and many satellites, including Australia’s own Optus C1 satellite is a dual use (military and civilian) satellite.
